Melanocortin-4 receptor (MC4R) is one of five G-protein-coupled receptors binding melanocortins that is implicated in the
control of feeding behavior and energy homeostasis. Six cattle populations (n = 594), including four Chinese indigenous breeds, Chinese Holstein, and a meat type breed (Angus), were used to detect single
nucleotide polymorphisms in 5′-untranslated region of MC4R gene by means of PCR–SSCP and DNA sequencing. Four linked SNPs (g.[−293C>G; −193A>T; −192T>G; −129A>G]) were identified.
The g.−293C>G and g.−129A>G could be genotyped with a PCR–RFLP using TaiI in three combined genotypes (AA, AB and BB). The two linked SNPs were associated with body weight and daily gain in Nanyang
aged 6 months (P < 0.05), but they had no significant effect on body weight and daily gain in Nanyang aged 24 months (P > 0.05). 相似文献

Transgenically expressed Syndecan-1 was found in the hypothalamic nuclei that control energy balance, and was associated with
maturity-onset obesity, while ghrelin has been shown to play important roles in the control of food intake, gastric acid secretion,
energy homeostasis, and glucose and lipid metabolism. However, the roles of genetic variations of Syndecan-1 and ghrelin on
growth trait have few been reported in cattle. Herein, five Chinese cattle breeds were analyzed by PCR–SSCP and DNA sequencing
methods. The bovine ghrelin gene showed eleven SNPs g.[267G>A, 271G>A, 290C>T, 326A>G, 327T>C, 420C>A, 569A>G, 945C>T, 993C>T,
4491A>G, 4644G>A] and three SNPs g.[420C>A, 569 A>G, 945C>T] were firstly detected in cattle. The bovine Syndecan-1 gene showed
two SNPs. One SNP showed a transition C>G at position 21514, resulting in a synonymous mutation p.G(GGC)169G(GGG) and another
showed a transversion C>T at position 22591, resulting in a synonymous mutation p.D(GAC)283D(GAT). In ghrelin gene, no significant
associations were revealed between any variant sites and body weight, average daily gain, body sizes for different growth
periods (6, 12, 18, and 24 months old), as well as for the milk yield at 305 days, milk protein rate and milk fat percentage.
However, the polymorphism of Syndecan-1 gene was significantly associated with bovine birth weight and body length. Hence,
we first suggested that Syndecan-1 gene could be regarded as molecular marker for superior birth weight and body length. 相似文献

The peroxisome proliferator-activated receptor γ (PPARγ) is a nuclear hormone receptor that regulates adipogenesis and many other biological processes. In the present study, we
carried out PCR–SSCP and DNA sequencing analyses to examine SNPs in coding region of the PPARγ gene. A total of 660 individuals from five Chinese cattle breeds were genotyped. We identified three SNPs and their associations
with meat quality traits were analyzed in 108 Qinchuan cattle. Two missense mutations and one synonymous mutation were found:
200 A > G (genotypes AA, AB and BB) resulting in D7G change, the silent substitution 42895 C > T (genotypes JJ and JI) and
72472 G > T (genotypes CC, DC and DD) producing Q448H change, respectively. The frequencies of PPARγ-A allele were 0.86, 0.83, 0.80, 0.72 and 0.87 for Qinchuan, Nanyang, Jiaxian, Luxi and Xianan populations, respectively.
The frequencies of PPARγ-J allele varied from 0.87 to 0.96 in the five populations. In the 72472 G > T locus, the frequencies of PPARγ-C allele were higher than PPARγ-D allele in the five populations, and ranged from 0.58 to 0.82. Least squares analysis revealed that in 42895 C > T locus,
there was a significant effect on tenderness in 18-20 months Qinchuan cattle (P < 0.01), and in the 72472 G > T locus, animals with the genotype DC had lower mean values than these with genotype CC (P < 0.01) for back fat thickness in 18–20 months, and animals with the genotype DD had lower mean values than these with genotypes
CC and DC (P < 0.01) for water holding capacity in 21–24 months (P < 0.01). The SNPs we have identified may contribute to establishing a more efficient selection program for improving of genetic
characteristics in indigenous Chinese cattle 相似文献

PCR-SSCP and DNA sequencing methods were employed to screen the genetic variation of VEGF gene in 671 individuals belonging to three Chinese indigenous cattle breeds including Nanyang, Jiaxian Red and Qinchuan.
Three haplotypes (A, B and C), four observed genotypes (AA, AB, BB and AC) and three new SNPs (6765T>C ss130456744, 6860A>G
ss130456745, 6893T>C ss130456746) were detected. The analysis suggested that one SNP (ss130456744) in the bovine VEGF gene had significant effects on birth weight, body weight and heart girth at 6 months old in the Nanyang breed (P < 0.05). The results showed that the SNP (ss130456744) in intron 2 of the VEGF gene is associated with early development and growth of Chinese cattle. These findings raise hope that this polymorphism
can be a molecular breeding marker in breeding strategies through marker assisted selection (MAS) in Chinese domestic cattle. 相似文献

In this study, polymorphism in the exon 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 of bovine NUCB2 gene was detected by PCR-SSCP and DNA sequencing methods in 686 individuals from three Chinese cattle breeds. Two haplotypes
(M and N), three observed genotypes (MM, MN and NN) and two SNPs (NC_007313: g. 27451G>A, NC_007313: g. 27472T>C) were detected. The frequencies of haplotypes M and N in inland
Chinese three breeds were 0.531–0.721 and 0.279–0.469 respectively. The studied showed that Nanyang, Jiaxian Red and Qinchuan
cattle populations were in Hardy–Weinberg equilibrium at SNPs locus of NUCB2 gene (P > 0.05). Polymorphism of the NUCB2 gene was shown to be associated with growth traits in Qingchuan and Nanyang cattle breed. The linkage of two mutant sites
in the bovine NUCB2 gene had significant effects on body length, body weight, heart girth, and average daily gain at 24 months (P < 0.05). Results of this study suggested that the NUCB2-gene-specific SNP may be a useful marker for growth traits in future marker-assisted selection programmes in inland Chinese
cattle. 相似文献

Transmembrane protein 18 (TMEM18) gene is expressed in the central nervous system that has recently been linked to human obesity and body mass index (BMI) in genome wide association studies (GWAS). In this study, two novel single nucleotide polymorphisms (SNPs), g.3835 G > A (aa. Gly > Ser) and g.3865 A > G were detected in cattle TMEM18 gene by DNA sequencing. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and forced PCR-RFLP methods were used to genotype the two SNPs in 1218 Chinese native cattle individuals. The association between novel SNPs and growth traits (especially on body weight and body height) in Nanyang cattle showed that individuals with GG genotype was higher than those with AA genotype at g.3835G>A locus (P < 0.05) in Nanyang cattle. Significant association also revealed that individuals of AA genotype at g. 3865 A>G locus were higher in terms of body weight, average daily gain, chest circunmference, body length (P < 0.05), body height and hucklebone width (P < 0.01) than GG genotypes in Nanyang cattle. Moreover, the effect of XspI-MluI combinations with growth traits in Nanyang cattle revealed that AAGG type had higher body weight, body length, chest circumference and average daily gain (P < 0.05) than GGAG in Nanyang cattle aged at 6 months. 相似文献

The objectives of this study were to identify single nucleotide polymorphisms (SNPs) in the promoter I (PI) region of the bovine acetyl‐CoA carboxylase‐α (ACACA) gene and to evaluate the extent to which they were associated with lipid‐related traits. Eight novel SNPs were identified, which were AJ276223:g.2064T>A (SNP1), g.2155C>T (SNP2), g.2203G>T (SNP3), g.2268T>C (SNP4), g.2274G>A (SNP5), g.2340A>G (SNP6), g.2350T>C (SNP7) and g.2370A>G (SNP8). Complete linkage disequilibrium was observed among SNP1, 2, 4, 5, 6 and 8. Phenotypic data were collected from 573 cross‐bred steers with six sire breeds, including Hereford, Angus, Brangus, Beefmaster, Bonsmara and Romosinuano. The genotypes of SNP1/2/4/5/6/8 were significantly associated with adjusted backfat thickness. The genotypes of SNP3 were significantly associated with triacylglycerol (TAG) content and fatty acid composition of longissimus dorsi muscle (LM) in Brangus‐, Romosinuano‐ and Bonsmara‐sired cattle. Cattle with g.2203GG genotype had greater concentrations of TAG, total lipid, total saturated fatty acid and total monounsaturated fatty acid than did cattle with g.2203GT genotype. The genotypes of SNP7 were significantly associated with fatty acid composition of LM. Cattle with genotype g.2350TC had greater amounts of several fatty acids in LM than did cattle with genotype g.2350CC. Our results suggested that the SNPs in the PI region of ACACA gene are associated with variations in the fatty acid contents in LM. 相似文献

Prolactin (PRL) plays a crucial role in the initiation and maintenance of lactation in mammals. In this study, seven PCR fragments
representing most important functional domains of PRL gene were screened for single nucleotide polymorphisms (SNPs) in Chinese Holsteins by single-strand conformation polymorphisms
and amplicons sequencing, and their genetic effects on milk production traits were evaluated. A total of four SNPs, including
two in the promoter (−1043A>G and −402A>G), one in intron 1 (+2723C>T) and one in exon 4 (+8398G>A) were identified in PRL gene. Statistical results showed significant associations between the promoter genotypes and the milk performance traits
in Chinese Holsteins. Cows with genotype P1-GG showed higher milk yields (P < 0.01), while cows with genotype P1-AA showed higher fat contents (P < 0.01). Haplotype analysis of two SNPs in promoter region revealed that the Hap(AG) was significantly associated with increased milk yields and Hap(AA) was associated with increased fat contents (P < 0.01). This is the second study reporting SNPs in the 5′-regulatory region of PRL gene, which interfere with milk production traits. 相似文献

PCR–SSCP and DNA sequencing methods were employed to screen the genetic variation of vascular endothelial growth factor (VEGF) gene in 675 individuals belonging to three Chinese indigenous cattle breeds including Qinchuan (QC), Jiaxian Red (JX) and
Nanyang (NY) breed. Three new single nucleotide polymorphisms (SNPs) (g.6765T > C ss130456744, g.6860A > G ss130456745, g.6893T > C
ss130456746) were found. One SNP (g.6765T > C) was detected in intron II of VEGF gene in all three breeds and the other two SNPs (g.6860A > G, g.6893T > C) were in exon III of VEGF gene only in NY breed. Among them, two synonymous mutations of exon III were identified: CCA (Pro) > CCG (Pro) at position
65th amino acid (aa) and TGT (Cys) > TGC (Cys) at position 76th aa of VEGF(190aa) in NY breed. Our study revealed that NY breed exhibited the most abundant genetic diversity in VEGF gene within the three cattle breeds. Furthermore, JX cattle breed was more similar to QC breed than to NY breed. Our genetic
data in the present study supported the hypothesis that the distribution pattern of Chinese indigenous cattle breeds was closely
related to the geographical and climatic background again. 相似文献

Myogenic factor 5 plays actively roles in the regulation of myogenesis. The aims of this study are to identify the evolution information of MYF5 protein among 10 domestic and mammalian animals, to uncover the expression patterns of MYF5 gene in calves and adults of Qinchuan cattle, and to expose the genetic variants of the MYF5 gene and explore its effect on cattle growth traits and beef quality traits in Qinchuan cattle. The bioinformatics results showed that the MYF5 proteins highly conserved in different mammalian or domestic animals apart from chicken. The expression level of MYF5 gene in the heart, muscle, lung, large intestine and liver was greater than that of other tissues. PCR amplicons sequencing identified four novel SNPs at g.5738A>G, g.5785C>T and g.5816A>G in the 3rd exon region and g.6535A>G in the 3’ UTR. Genotypic frequencies of g.5785C>T was harshly deviated from the HWE (P < .05). Genetic diversity was low or intermediate for the four SNPs and those SNPs were in the weak linkage disequilibrium. Association analysis results indicated g.5785C>T, g.5816A>G and g.6535A>G significant effect on growth performance and beef quality traits of Qinchuan cattle. H1H3 diplotype had greater body size and better beef quality. All the results implicate that the MYF5 gene might be applied as a promising candidate gene in Qinchuan cattle breeding. 相似文献

This study was designed to screen the crossbred pigs for SNPs in five candidate genes, associated with pork quality traits and to differentiate their genotypes by PCR–RFLP. The results indicated that genotypes of crossbred pigs were NN (90%) and Nn (10%) for RYR1; RR (83%) and QR (17%) for PRKAG3; HH (98%), Hh (1%) and hh (1%) for HFABP; DD (99%) and CD (1%) for MYF-5; and AG (57%), GG (26%) and AA (17%) for MC4R SNPs, respectively. Allelic frequencies for five SNPs {RYR1 (1843C>T), PRKAG3 (c.599G>A), HFABP (c.1322C>T), MYF-5 (c.1205A>C) and MC4R (c.1426A>G)} were 0.95 and 0.05 (N/n), 0.08 and 0.92 (Q/R), 0.99 and 0.01 (H/h), 0.00 and 1.00 (C/D) and 0.45 and 0.55 (A/G), respectively. The effect of RYR1 (1843C>T) SNP was significant on pH45 (P?<?0.05), pH24 (P?<?0.05) and protein % (P?<?0.05). The PRKAG3 (c.599G>A) and MC4R (c.1426A>G) SNP had significant association with dressing percentages. The results revealed that RYR1, PRKAG3 and MC4R SNPs may be used in marker associated selection for pork quality traits in crossbred pigs. 相似文献

β-lactoglobulin (β-LG) is the major whey protein in the milk. In order to investigate the polymorphism of β-LG variant B precursor
(β-LG B*: GenBank accession no. DQ489319) gene and its effects on the milk traits, the single-strand conformation polymorphism
method (PCR-SSCP) were adopted to analyze polymorphism between 5229th and 5476th bp in the β-LG B* gene in Chinese Holstein.
Four genotypes were found (AA, AB, AC and ABC) and 3 single nucleotide polymorphisms (SNPs) were detected (g.5239C>A, g.5240A>C,
g.5305C>T and mix type g.5305C/T) in the exon 4 of β-LG B* gene. It was also found that the protein contents of AB, AC and
ABC dairy cows were higher than AA (P < 0.05), and AC cows were the highest among them. Three SNPs (g.5239C>A, g.5240A>C and g.5305C>T) might affect the milk trait
and all of them were high polymorphism (0.5 < PIC < 1.0). In further researches, the three SNPs also caused amino acid change
(Asp>Glu, Thr>Pro and Ala>Val) respectively, and the spatial secondary and tertiary structure forecasting result also showed
that single amino acid change influence protein spatial structure change in Chinese Holstein. Taken together, it is suggested
that these SNPs change β-LG B* gene structure and expression. The polymorphism possibly holds the secret of milk protein and
fat contents in the milk of Chinese Holstein. 相似文献

MC4R belongs to a seven-transmembrane G-protein-coupled receptor which may regulate body composition and insulin action. Many
mutations in the MC4R gene are associated with obesity, energy expenditure and serum triglyceride levels in human and animals. Six mutations in
the MC4R gene were identified in our study (-293C>G, -193A>T, -192T>G, -129A>G, -84T>C and 1,069C>G). The -129A>G was significantly
associated with live weight (LW) (P < 0.05), Cattle with the genotypes AG and GG had higher LW than genotype AA. The 1,069C>G was significantly associated with
LW, carcass weight (CW), backfat thickness and marbling score (MS). Cattle with the genotype GG had higher LW, CW and MS than
genotype CC; Cattle with the genotypes GG and CG had higher MS than CC. The results suggested that -129A>G and 1,069C>G SNP
of the MC4R gene may be useful as a genetic marker for carcass and meat quality traits in Qinchuan cattle. 相似文献

Quantitative trait loci for fat deposition and carcass traits have been identified in the vicinity of the gene encoding phosphodiesterase 1B (PDE1B) on bovine chromosome 5. Therefore, the PDE1B gene can be considered as a positional and functional candidate gene
for carcass traits in beef cattle. This study aimed to identify single nucleotide polymorphisms (SNPs) in the PDE1B gene and
to evaluate their associations with carcass traits in Korean cattle. Eight SNPs, g.440T>G, g.17122A>G, g.17507A>C, g.17575A>G,
g.17607T>C, g.17609C>A, g.17692C>T, and g.17707C>G, were identified in the region ranged from exon 1 to intron 6. Five of
them were used for association analysis because of their availability of restriction fragment length polymorphisms. As a result,
g.17122A>G in intron 3 was significantly associated with backfat thickness (BFT), and g.17507A>C in exon 5 was associated
with longissimus dorsi muscle area (LMA, P < 0.05). Animals with the AG genotype of g.17122 had thicker BFT than those with the AA genotype. Animals with the AA or
AC genotype of g.17507A>C had larger LMA than those with the CC genotype. We suggested the PDE1B gene as a candidate gene
for carcass traits of beef cattle. Fine mapping would be required for application to marker-assisted selection. 相似文献

This study was aimed to search new genetic variants in the bovine FABP4 gene as molecular markers for meat quality and carcass traits. PCR–RFLP analysis revealed that three SNPs located at nucleotide
positions g.2834C>G, g.3533T>A, and g.3691G>A were identified based on a GenBank accession number (NC_007312.4). Sequence
analysis revealed that SNPs were located in intron 1 (g.2834C>G) and 2 (g.3533T>A), and an exon 3 (g.3691G>A), showing allele
frequencies as 0.592, 0.579, and 0.789, respectively. Genetic variabilities of heterozygosity (He) and polymorphic information
contents (PIC) were estimated for g.2834C>G (0.608 and 0.531), g.3533T>A (0.615 and 0.539), and g.3691G>A (0.498 and 0.401)
loci, respectively. A SNP located in the exon 3 of FABP4 was characterized and associated with desirable increases of MS (marbling scores) and MG (meat quality grades) in Hanwoo.
The statistical analysis revealed that additive effects by GG genotypes in g.3691G>A SNP were significantly greater than AA
genotypes in MS and MG traits. These findings suggest that the FABP4g.3691G>A SNP will be a useful candidate locus to maximize economic benefits for cattle populations. 相似文献

Soybean cyst nematode (SCN; Heterodera glycines Ichinohe) is one of the most destructive pests in the cultivation of soybean (Glycine max (L.) Merr.) worldwide. Markers based on the SCN resistance gene will enable efficient marker-assisted selection (MAS). We
sequenced the candidate gene rhg1 in six resistant and two susceptible soybean genotypes and identified 37 SNPs (single nucleotide polymorphisms) among the
sequences, of which 11 were in the coding region. Seven of these 11 SNPs led to changes in the amino acid sequence of the
gene. The amino acid sequence we obtained differs from the previously published one by a stretch of 26–27 amino acids. Six
codominant allele-specific SNP markers based on agarose gel detection were developed and tested in 70 genotypes, among which
occurred only nine different haplotypes. Two neutrality tests (Tajima’s D and Fu and Li’s F) were significant for the six SNP loci in the 70 genotypes, which is consistent with intensive directional selection. A strong
LD pattern was detected among five SNPs except 2868T > C. Two SNPs (689C > A and 757C > T) formed one haplotype (689C-757C)
that was perfectly associated with SCN resistance. The new allele-specific PCR markers located in the alleged sequence of
the rhg1 candidate gene, combined with the microsatellite marker BACR-Satt309, will significantly improve the efficiency of MAS during
the development of SCN-resistant cultivars. 相似文献

This study was designed to investigate the candidate single nucleotide polymorphisms (SNPs) in the exon’s region of bovine diacylglycerol O-acyltransferase (DGAT1) gene using bioinformatics and experimental methods. A total of 17 SNPs were screened from public data resources and DNA sequencing. Three SNPs (c.572A>G, c.1241C>T and c.1416T>G) of these candidate SNPs were genotyped by created restriction site-polymerase chain reaction (CRS-PCR) methods. The gene-specific SNP markers and their effects on meat and carcass fatness quality traits were evaluated in Chinese commercial cattle. The c.572A>G and c.1416T>G significantly effected on backfat thickness, longissimus muscle area, marbling score, fat color and Warner-Bratzler shear force. No significant association was detected between the c.1241C>T and measured traits. Results from this study suggested that the SNP markers may be effective for the marker-assisted selection of meat and carcass fatness quality traits, and added new evidence that DGAT1 gene is an important candidate gene for the improvement of meat and carcass fatness quality in beef cattle industry. 相似文献

The relation of Two single nucleotide polymorphisms (SNPs) at the adiponectin locus (+45T/G and +276G/T) with coronary artery
disease (CAD) is controversial. The aim of the present study was to evaluate the genetic influence of the adiponectin gene
polymorphisms in the development of CAD among patients with Type 2 diabetes (T2D). The adiponectin genotypes were detected
by polymerase chain reaction and restriction analysis (PCR-RFLP) in our patients. Two adiponectin gene (ADIPOQ) SNPs (i.e.
SNPs +45T>G and +276G>T) were genotyped in 114 Type 2 diabetic subjects with CAD, and 127 Type 2 diabetic patients without
CAD. Demographic and anthropometric data along with plasma biochemistry including lipids, glycemic indices, and adiponectin
were collected. There was a significant difference in the distribution of genotypes of +45T/G and +276G/T between CAD and
non-CAD individuals (P < 0.05). Based on our results SNP+276G>T is associated with decreased risk of CAD after adjustment for potential confounding
factors [adjusted OR = 0.39 (95%CI: 0.22–0.68); P = 0.001]. Similar findings were not observed for the +45T>G SNP. Two haplotypes 45T-276T and 45G-276T were associated with
a decreased risk of CAD [adjusted OR = 0.47 (95% CI: 0.32–0.94); P = 0.03 and adjusted OR = 0.33 (95% CI: 0.13–0.83); P = 0.02 respectively]. No significant difference was observed between HOMA-IR, BMI, waist circumference, history of hypertension,
HbA1C, and lipid concentrations regarding the two SNPs. In conclusion, these findings suggest that T allele of +276G>T SNP
is significantly associated with decreased risk of CAD in T2D Patients. Also Haplotype analysis showed that two haplotypes
45T-276T and 45G-276T were associated with a decreased risk of CAD. 相似文献
