Serum levels of appetite-regulating hormones and pro-inflammatory cytokines are ameliorated by a CLA diet and endurance exercise in rats fed a high-fat diet

[Purpose]

This study examined whether conjugated linoleic acid (CLA) supplementation and endurance exercise affect appetite-regulating hormones and pro-inflammatory cytokines in rats.

[Methods]

Seven-week-old male Sprague-Dawley rats were divided randomly into the high-fat diet sedentary group (HS, n=8), the 1.0% CLA supplemented high-fat diet sedentary group (CS, n=8), and the 1.0% CLA supplemented high-fat diet exercise group (CE, n=8). Rats in the CE group swam 60 min/day, 5 days/week for 4 weeks.

[Results]

Leptin and insulin levels in the CS and CE groups were significantly lower than those in the HS group (p<0.001), whereas leptin (p<0.01) and insulin (p<0.05) levels decreased significantly in the CE compared to those in the CS group. Interleukin (IL)-1β (p<0.001) and IL-6 (p<0.01) levels in the CS and CE groups decreased significantly compared to those in the HS group. Leptin (IL-1β: r=0.835, p<0.001), IL-6 (r=0.607, p<0.05), insulin (IL-1β: r=0.797, p<0.01), and IL-6 (r=0.827, p<0.01) levels were positively related with pro-inflammatory cytokine levels.

[Conclusion]

Endurance exercise may play an important role during CLA supplementation of rats on a high-fat diet.     

<Emphasis Type="Italic">Agaricus bisporus</Emphasis> supplementation reduces high-fat diet-induced body weight gain and fatty liver development

Obesity is a global epidemic characterized not only by excessive fat deposition but also by important complications such as nonalcoholic liver steatosis. Beneficial antiobesogenic effects have been described for some mushrooms. The current study aimed to demonstrate the protective effect of Agaricus bisporus (AB) supplementation against the metabolic alterations induced by high-fat-diet (HFD) feeding. Eight-week-old C57BL/6J mice were fed for 10 weeks with one of the following diets: (1) control diet (n?=?7), (2) HFD (n?=?7), (3) HFD supplemented with 5% AB (n?=?9), and (4) HFD supplemented with 10% AB (n?=?9). A pair-fed group was also included for the 10% AB group (n?=?6). The impact of AB supplementation on food intake, body weight gain, and liver and fat pad weights was examined. Biochemical, histological, and molecular parameters were also analyzed. Dietary supplementation with 10% AB reduced the HFD-induced increase in body, epididymal, and mesenteric fat weights (p?<?0.01, p?<?0.05, and p?<?0.05, respectively). Supplementation with AB also reduced liver damage in a dose-dependent manner (p?<?0.01 and p?<?0.001). This effect was confirmed by histological analysis that showed that liver steatosis was markedly reduced in mice fed with AB. The beneficial properties of 10% AB supplementation appear to be mediated through a decrease in food intake and via stimulation of mesenteric and hepatic free-fatty acid beta-oxidation, along with a decrease in epidydimal and hepatic expression of CD36. In conclusion, supplementation with AB prevents excessive body weight gain and liver steatosis induced by HFD consumption.     

Effect of high-intensity interval training on muscle remodeling in rheumatoid arthritis compared to prediabetes

Background

Sarcopenic obesity, associated with greater risk of cardiovascular disease (CVD) and mortality in rheumatoid arthritis (RA), may be related to dysregulated muscle remodeling. To determine whether exercise training could improve remodeling, we measured changes in inter-relationships of plasma galectin-3, skeletal muscle cytokines, and muscle myostatin in patients with RA and prediabetes before and after a high-intensity interval training (HIIT) program.

Methods

Previously sedentary persons with either RA (n = 12) or prediabetes (n = 9) completed a 10-week supervised HIIT program. At baseline and after training, participants underwent body composition (Bod Pod^®) and cardiopulmonary exercise testing, plasma collection, and vastus lateralis biopsies. Plasma galectin-3, muscle cytokines, muscle interleukin-1 beta (mIL-1β), mIL-6, mIL-8, muscle tumor necrosis factor-alpha (mTNF-α), mIL-10, and muscle myostatin were measured via enzyme-linked immunosorbent assays. An independent cohort of patients with RA (n = 47) and age-, gender-, and body mass index (BMI)-matched non-RA controls (n = 23) were used for additional analyses of galectin-3 inter-relationships.

Results

Exercise training did not reduce mean concentration of galectin-3, muscle cytokines, or muscle myostatin in persons with either RA or prediabetes. However, training-induced alterations varied among individuals and were associated with cardiorespiratory fitness and body composition changes. Improved cardiorespiratory fitness (increased absolute peak maximal oxygen consumption, or VO₂) correlated with reductions in galectin-3 (r = ?0.57, P = 0.05 in RA; r = ?0.48, P = 0.23 in prediabetes). Training-induced improvements in body composition were related to reductions in muscle IL-6 and TNF-α (r < ?0.60 and P <0.05 for all). However, the association between increased lean mass and decreased muscle IL-6 association was stronger in prediabetes compared with RA (Fisher r-to-z P = 0.0004); in prediabetes but not RA, lean mass increases occurred in conjunction with reductions in muscle myostatin (r = ?0.92; P <0.05; Fisher r-to-z P = 0.026). Subjects who received TNF inhibitors (n = 4) or hydroxychloroquine (n = 4) did not improve body composition with exercise training.

Conclusion

Exercise responses in muscle myostatin, cytokines, and body composition were significantly greater in prediabetes than in RA, consistent with impaired muscle remodeling in RA. To maximize physiologic improvements with exercise training in RA, a better understanding is needed of skeletal muscle and physiologic responses to exercise training and their modulation by RA disease–specific features or pharmacologic agents or both.

Complete Amino Acid Sequence of a Copper/Zinc-Superoxide Dismutase from Ginger Rhizome

Superoxide dismutase (SOD) is an antioxidant enzyme protecting cells from oxidative stress. Ginger (Zingiber officinale) is known for its antioxidant properties, however, there are no data on SODs from ginger rhizomes. In this study, we purified SOD from the rhizome of Z. officinale (Zo-SOD) and determined its complete amino acid sequence using N terminal sequencing, amino acid analysis, and de novo sequencing by tandem mass spectrometry. Zo-SOD consists of 151 amino acids with two signature Cu/Zn-SOD motifs and has high similarity to other plant Cu/Zn-SODs. Multiple sequence alignment showed that Cu/Zn-binding residues and cysteines forming a disulfide bond, which are highly conserved in Cu/Zn-SODs, are also present in Zo-SOD. Phylogenetic analysis revealed that plant Cu/Zn-SODs clustered into distinct chloroplastic, cytoplasmic, and intermediate groups. Among them, only chloroplastic enzymes carried amino acid substitutions in the region functionally important for enzymatic activity, suggesting that chloroplastic SODs may have a function distinct from those of SODs localized in other subcellular compartments. The nucleotide sequence of the Zo-SOD coding region was obtained by reverse-translation, and the gene was synthesized, cloned, and expressed. The recombinant Zo-SOD demonstrated pH stability in the range of 5–10, which is similar to other reported Cu/Zn-SODs, and thermal stability in the range of 10–60?°C, which is higher than that for most plant Cu/Zn-SODs but lower compared to the enzyme from a Z. officinale relative Curcuma aromatica.     

Is there a relationship between <Emphasis Type="Italic">PPARD</Emphasis> T294C/<Emphasis Type="Italic">PPARGC1A</Emphasis> Gly482Ser variations and physical endurance performance in the Korean population?

The peroxisome proliferator-activated receptor δ (PPARD) and peroxisome proliferator-activated receptor γ coactivator 1α (PPARGC1A) genes recently have been suggested to have an association with athletic performance and physical endurance. These gene products are reported to be crucial components in training-induced muscle adaptation, since they are related with mRNA and/or protein activity in coordinated response to exercise. To assess the possible contribution of the PPARD T294C/PPARGC1A Gly482Ser polymorphism to differences in physical endurance, we performed a population-based study of 111 Korean athletes and 145 healthy controls based on their genotype distribution of the genes. The two loci were found to be not deviated from Hardy–Weinberg equilibrium. There were no differences in genotype distribution of PPARD T294C and PPARGC1A Gly482Ser between the athletic group and controls (p > 0.05). In contrast, we found a significant association between the PPARGC1A Gly482Ser polymorphism and the 20 m shuttle run activity (a measure of endurance performance) in the athletic group (p = 0.003). The result showed a remarkable increase in the numbers of shuttle run ratio from subjects with the PPARGC1A Gly/Gly genotype (85.29 ± 28.80) than those with the Gly/Ser (58.05 ± 32.76) and Ser/Ser (68.38 ± 30.47) genotypes. Thus, our data imply that the PPARGC1A Gly/Gly genotype may provide a beneficial effect on elite-level endurance status, although functional studies with larger sample sizes are necessary to elucidate these findings.     

Courtship behavior,communicative sound production and resistance to stress in Drosophila mutants with defective <Emphasis Type="Italic">agnostic</Emphasis> gene coding for LIMK1

To elucidate the role of one of the main elements of signal cascade of actin remodeling—LIM-kinase 1 (LIMK1)—in the control of animal behavior we have studied the characteristics of courtship behavior, parameters of acoustic communicative signals and their resistance to heat shock (HS, 37°C, 30 min) in Drosophila melanogaster males with the agn ^ts3 mutation in the agnostic locus which contains CG1848 gene for LIMK1. The data obtained were compared with the results of our previous similar investigation on wild type CS males [1]. Flies were divided into 4 groups. The males of control groups were not subjected to heat shock. Other groups were comprised of males subjected to heat shock either at the beginning of larval development when the mushroom body neuroblasts are predominantly dividing (groups HS1), or at the prepupal stage when the brain central complex is developing (groups HS2), or at the imago stage 1 hour before the test (groups HS). All males were tested at the age of 5 days. Virgin and fertilized CS females were used as courtship objects. Comparison of control groups of the wild type (CS) and mutant strains has shown that the mutation agn ^ts3 does not affect the main parameters of courtship behavior (courtship latency, the rapidity of achieving copulation, courtship efficiency) but leads to: a decrease in sexual activity, an increase in duration of sound trains in the songs and to a slight increase in the rate and stability of singing pacemakers. When compared to wild type, the agn ^ts3 males are more resistant to HS given 1 hour before the test. After HS their courtship intensity does not decrease and the main parameters of their courtship behavior and communicative sound signals either do not change, or appear to be even better stabilized. The frequency of distorted sound pulses (an indicator of frequency of impairments in the activity pattern of neuro-motor circuits of the singing center) decreases, and the working rate and stability of pacemakers of the pulse and the sine songs increases. Therefore, although the sharply elevated LIMK1 and p-cofilin levels detected by immunofluorescent techniques in the cells of agn ^ts3 mutants can lead to dramatic defects in learning and memory [2] accompanied by a decline of motivation of males, they do not appreciably affect the neuro-motor coordination during singing. The higher resistance of characteristics of the mutant behavior and communicative sound signals to heat shock is in agreement with the fact that the extremely high LIMK1 and P-cofilin levels fall down to normal values after HS and both the learning acquisition and memory formation are restored.     

Chromosomes of Ichneumonidae (Hymenoptera): New results and conclusions

New data were obtained on the karyotypes of 12 parasitic wasp species of the family Ichneumonidae: Scambus detritus (2n = 28), S. vesicarius (2n = 28), Pimpla contemplator (2n = 36), Theronia atalantae (2n = 24), Stenomacrus sp. 2 (n = 18, 2n = 36), Phygadeuon sp. 3 (2n = 32), Ichneumon memorator (2n = 24), I. vorax (2n = 22), Lymantrichneumon disparis (2n = 26), Orthopelma mediator (n = 15, 2n = 30), Lissonota buccator (2n = 22), and Trichionotus flexorius (2n = 16). Chromosomes of Anomaloninae were studied for the first time. The data on the karyotype structure of the subfamily Orthopelmatinae were revised. Various aspects of chromosome variability in Ichneumonidae are discussed.     

New data on chromosomes of parasitic wasps of the subfamily Ichneumoninae (Hymenoptera,Ichneumonidae)

Some aspects of the chromosomal variability of Ichneumoninae are discussed.     

Exome sequencing confirms molecular diagnoses in 38 Chinese families with hereditary spherocytosis

Hereditary spherocytosis(HS), the most common cause of congenital hemolytic anemia, is caused by deficiency of the erythrocyte membrane proteins. Five causative genes(ANK1, SPTB, SPTA1, SLC4 A1, and EPB42) have been identified. To date,molecular genetic studies have been performed in different populations, including the American, European, Brazilian, Japanese and Korean populations, whereas only a few studies have been described in the Chinese population. Here, by reanalysis of the exome data, we revealed causative mutations and established a definitive diagnosis of HS in all 38 Chinese families. We found 34 novel mutations and four reported mutations in three known HS-causing genes—17 in ANK1, 17 in SPTB and four in SLC4 A1,suggesting that ANK1 and SPTB are the major genes in Chinese patients with HS. All of the ANK1 or SPTB mutations, scattered throughout the entire genes, are non-recurrent; and most of them are null mutations, which might cause HS via a haploinsufficiency mechanism. De novo mutations in ANK1 or SPTB often occur with an unexpected high frequency(87.5% and64.2%, respectively). Our study updates our knowledge about the genetic profile of HS in Chinese and shows that family-based,especially parent-offspring trio, sequencing analysis can help to increase the diagnostic power and improve diagnostic efficiency.     

Elemental Analysis of Whole and Protein Separated Blood Serum of Patients with Systemic Lupus Erythematosus and Sjögren’s Syndrome

Data on the effects of selenium supplementation on clinical signs and metabolic profiles in women at risk for intrauterine growth restriction (IUGR) are scarce. This study was designed to assess the effects of selenium supplementation on clinical signs and metabolic status in pregnant women at risk for IUGR. This randomized double-blind placebo-controlled clinical trial was performed among 60 women at risk for IUGR according to abnormal uterine artery Doppler waveform. Participants were randomly assigned to intake either 100 μg selenium supplements as tablet (n = 30) or placebo (n = 30) for 10 weeks between 17 and 27 weeks of gestation. After 10 weeks of selenium administration, a higher percentage of women in the selenium group had pulsatility index (PI) of <1.45) (P = 0.002) than of those in the placebo group. In addition, changes in plasma levels of total antioxidant capacity (TAC) (P < 0.001), glutathione (GSH) (P = 0.008), and high-sensitivity C-reactive protein (hs-CRP) (P = 0.004) in the selenium group were significant compared with the placebo group. Additionally, selenium supplementation significantly decreased serum insulin (P = 0.02), homeostasis model of assessment-estimated insulin resistance (HOMA-IR) (P = 0.02), and homeostatic model assessment for B-cell function (HOMA-B) (P = 0.02) and significantly increased quantitative insulin sensitivity check index (QUICKI) (P = 0.04) and HDL-C levels (P = 0.02) compared with the placebo. We did not find any significant effect of selenium administration on malondialdehyde (MDA), nitric oxide (NO), fasting plasma glucose (FPG), and other lipid profiles. Overall, selenium supplementation in pregnant women at risk for IUGR resulted in improved PI, TAC, GSH, hs-CRP, and markers of insulin metabolism and HDL-C levels, but it did not affect MDA, NO, FPG, and other lipid profiles.Clinical trial registration number http://www.irct.ir: IRCT201601045623N64.     

Feasibility and relevance of compound strain imaging in non-stenotic arteries: comparison between individuals with cardiovascular diseases and healthy controls

Background

Compound strain imaging is a novel method to noninvasively evaluate arterial wall deformation which has recently shown to enable differentiation between fibrous and (fibro-)atheromatous plaques in patients with severe stenosis. We tested the hypothesis that compound strain imaging is feasible in non-stenotic arteries and provides incremental discriminative power to traditional measures of vascular health (i.e., distensibility coefficient (DC), central pulse wave velocity [cPWV], and intima-media thickness [IMT]) for differentiating between participants with and without a history of cardiovascular diseases (CVD).

Methods

Seventy two participants (60 ± 7 years) with non-stenotic arteries (IMT < 1.1 mm) were categorized in healthy participants (CON, n = 36) and CVD patients (n = 36) based on CVD history. Participants underwent standardised ultrasound-based assessment (DC, cPWV, and IMT) and compound strain imaging (radial [RS] and circumferential [CS] strain) in left common carotid artery. Area under receiver operating characteristics (AROC)-curve was used to determine the discriminatory power between CVD and CON of the various measures.

Results

CON had a significantly (P < 0.05) smaller carotid IMT (0.68 [0.58 to 0.76] mm) than CVD patients (0.76 [0.68 to 0.80] mm). DC, cPWV, RS, and CS did not significantly differ between groups (P > 0.05). A higher CS or RS was associated with a higher DC (CS: r = ?0.32;p < 0.05 and RS: r = 0.24;p < 0.05) and lower cPWV (CS: r = 0.24;p < 0.05 and RS: r = ?0.25;p < 0.05). IMT could identify CVD (AROC: 0.66, 95%-CI: 0.53 to 0.79), whilst the other measurements, alone or in combination, did not significantly increase the discriminatory power compared to IMT.

Conclusions

In non-stenotic arteries, compound strain imaging is feasible, but does not seem to provide incremental discriminative power to traditional measures of vascular health for differentiation between individuals with and without a history of CVD.

     

Three <Emphasis Type="Italic">P5CS</Emphasis> genes including a novel one from <Emphasis Type="Italic">Lilium regale</Emphasis> play distinct roles in osmotic,drought and salt stress tolerance

Proline accumulations in abiotically stressed plants is generally considered to benefit their stress tolerance. The Δ¹-Pyrroline-5-carboxylate synthetase (P5CS) gene family, which encodes the rate-limiting enzyme in proline biosynthesis pathway, usually contains two duplicated genes in most plants. However, three P5CS genes including LrP5CS1, LrP5CS2 as well as a third one, LrP5CS3, were isolated from Lilium regale. LrP5CS3 is highly identical to LrP5CS1 in amino acid sequences, indicating they could come from a paralogous duplication. The phylogenetic tree suggested that the duplication of LrP5CS occurred independently after the divergence of Liliales and commelinoids. The expression of LrP5CS1 was strongly induced in leaves and roots both under drought and salinity, while that of LrP5CS3 was upregulated more moderately. LrP5CS2 stayed almost constitutive under stress. LrP5CS1 exhibited the highest activity after expressed in E. coli. Overexpression of LrP5CS genes conferred enhanced osmotic, drought and salt tolerance on transgenic Arabidopsis without negative effects in unstressed condition. Under salt stress, lines LrP5CS2 accumulated fewer proline than others, and lines LrP5CS1 grew better in root elongation. The roots of lines LrP5CS3 grew better than all others under unstressed condition and osmotic stress. Our study suggests that the three LrP5CS genes play distinct roles respectively in proline accumulation and abiotic stress tolerance.     

The origin of the North Indian sugarcanes

The “North Indian sugarcanes”, cultivated by Indian peasants during many centuries, have been studied morphologically very exactly byC. A. Barber from 1910 to 1920. They were named “Saccharum Barberi” byJeswiet. Barber distinguished four groups. In 1931 the present author found the following chromosome numbers in these groups: 2n=116 and 2n=82 in the Sunnabile group; 2n=82 in the Mungo group; 2n=124 and 2n=107 in the Nargori group and about 91 in the Saretha group. The first three groups are sterile, the last is fertile. It is shown that the North Indian sugarcanes are hybrids between ancient indigenous sugar canes with a basic number of 17 chromosomes, and forms ofS. spontaneum withn=40,n=48 andn=56 respectively. Differences in the numbers of chromosomes contributed by the mother type may in part have their origin in endo-duplication, as commonly observed inSaccharum hybrids. Details are presented in Table 2. The differences found between different forms of IndianS. spontaneum in respect to chromosome number, sugar content and mosaic resistance may be attributed to intercrossing with canes of the fertile Saretha group.     

Dependence of endurance performance on <Emphasis Type="Italic">ACE</Emphasis> gene polymorphism in athletes

A group of elite 400-m distance runners carrying different alleles of the polymorphic angiotensinconverting enzyme (ACE) gene participated in an experiment that included aerobic exercise accompanied by measurement of the heart rate (HR) before, during, and after the exercise. Upon determination of the genotype for the ACE gene, the athletes were divided into three subgroups, carrying the II, ID, and DD alleles of the ACE gene. All athletes performed the same exercise: 25 min of running at an HR of 165–170 beats/min. The runners with the II genotype ran a significantly (p < 0.01) longer distance than the runners with the ID and DD genotypes. After the exercise, the HR recovery was the fastest in the runners with the II genotype.     

Bacterial metabolites from intra- and inter-species influencing thermotolerance: the case of <Emphasis Type="Italic">Bacillus cereus</Emphasis> and <Emphasis Type="Italic">Geobacillus stearothermophilus</Emphasis>

Bacterial metabolites with communicative functions could provide protection against stress conditions to members of the same species. Yet, information remains limited about protection provided by metabolites in Bacillus cereus and inter-species. This study investigated the effect of extracellular compounds derived from heat shocked (HS) and non-HS cultures of B. cereus and Geobacillus stearothermophilus on the thermotolerance of non-HS vegetative and sporulating B. cereus. Cultures of B. cereus and G. stearothermophilus were subjected to HS (42 or 65 °C respectively for 30 min) or non-HS treatments. Cells and supernatants were separated, mixed in a combined array, and then exposed to 50 °C for 60 min and viable cells determined. For spores, D values (85 and 95 °C) were evaluated after 120 h. In most cases, supernatants from HS B. cereus cultures added to non-HS B. cereus cells caused their thermotolerance to increase (D ₅₀ 12.2–51.9) when compared to supernatants from non-HS cultures (D ₅₀ 7.4–21.7). While the addition of supernatants from HS and non-HS G. stearothermophilus cultures caused the thermotolerance of non-HS cells from B. cereus to decrease initially (D ₅₀ 3.7–7.1), a subsequent increase was detected in most cases (D ₅₀ 18–97.7). In most cases, supernatants from sporulating G. stearothermophilus added to sporulating cells of B. cereus caused the thermotolerance of B. cereus 4810 spores to decline, whereas that of B. cereus 14579 increased. This study clearly shows that metabolites in supernatants from either the same or different species (such as G. stearothermophilus) influence the thermotolerance of B. cereus.     

Influence of climatic factors on tree growth in riparian forests in the humid and dry savannas of the Volta basin,Ghana

Key message

The paper demonstrates the prospects and applications of dendrochronology for understanding climate change effects on riparian forests in the savanna landscape. 

Abstract

Riparian trees in savannas have a potential for dendro-climatic studies, but have been neglected hitherto. We examined ring-width series of Afzelia africana (evergreen) and Anogeissus leiocarpus (deciduous) to study the influence of climatic factors on the growth of riparian trees in the humid (HS) and dry (DS) savanna zones of the Volta basin in Ghana. A total of 31 stem discs belonging to A. africana and A. leiocarpus were selected from HS and DS to establish species-specific local chronologies of tree growth. Each individual of A. africana and A. leiocarpus from the two savanna sites showed distinct growth rings. Cross-dating of individual tree-ring patterns was successful using standard dendrochronological techniques. The mean annual growth rates of A. africana in the HS (1.38 ± 0.09) and DS (1.34 ± 0.08) were not statistically different. Furthermore, mean annual growth rate of A. leiocarpus in the DS (3.75 ± 0.27) was higher than in the HS (2.83 ± 0.16) suggesting that species in drier environment can have higher growth rates when sufficient soil moisture is available. The growth rates of both species at the same sites were different, which might indicate different water use strategies. High correlations of individual tree-ring series of A. africana and A. leiocarpus trees at HS and DS suggest a strong climatic forcing controlled by the seasonal movement of the inter-tropical convergence zone. The annual growth of A. africana and A. leiocarpus at both the HS and DS was significantly correlated with local temperature and precipitation. The negative correlations of the growth of the two tree species to global sea surface temperatures were however, indications that the growth of riparian forests can be impacted during El Niño-Southern Oscillation years. The result of our study shows that riparian trees in the humid and dry savanna zones of West Africa can be successfully used for dendrochronological studies.

     

Cell culture system versus adventitious root culture system in Asian and American ginseng: a collation

Panax ginseng and Panax quinquefolius of Panax genus are valuable as health foods as well as pharmaceuticals for the treatment of cancer, diabetes and ageing as these plants possess saponins. In the current study, Cell and adventitious root cultures of P. ginseng and P. quinquefolius were investigated for the biomass, cell division, saponin content and ginsenosides profile from four lines namely P. quinquefolius (AM), P. ginseng mountain (Mt.) Baekdu line, P. ginseng Cheong-sol line (CS) and P. ginseng CBN line (CBN) with the objective of comparing cell and adventitious root systems to check their efficacy for the production of ginseng saponins. Additionally, genes related to ginsenoside biosynthesis were also analyzed concerning to cell and adventitious root lines. The results indicated that various cell lines were better in multiplication and growth compared to adventitious root lines. However, adventitious root lines showed higher accumulation of dry biomass (1.5–2 fold) than that of cell lines. CS adventitious root line showed higher saponin content and ginsenoside productivity (10.48 mg·g^?1 DW, 12.88 mg·L^?1, respectively) than that of CS cell line (9.50 mg·g^?1 DW, 2.39 mg·L^?1, respectively). Especially, Rd ginsenoside productivity of CS adventitious root line recorded fourfold higher than CS cell line. Genes which are related to ginsenoside biosynthesis such as P. ginseng squalene synthase (PgSS2), P. ginseng squalene epoxidase (PgSE2), P. ginseng protopanaxadial synthase (PgPPDS) and P. ginseng protopanaxatriol synthase (PgPPTS) were analyzed by real time quantitative polymerase chain reaction to support ginsenoside production. The adventitious root culture system described in this study is useful system for biomass and ginsenoside production.
