Background:
Vascular growth is a prerequisite for adipose tissue (AT) development and expansion. Some AT cytokines and hormones have effects on vascular development, like vascular endothelial growth factor (VEGF‐A), angiopoietin (ANG‐1), ANG‐2 and angiopoietin‐like protein‐4 (ANGPTL‐4).Methods:
In this study, the independent and combined effects of diet‐induced weight loss and exercise on AT gene expression and proteins levels of those angiogenic factors were investigated. Seventy‐nine obese males and females were randomized to: 1. Exercise‐only (EXO; 12‐weeks exercise without diet‐restriction), 2. Hypocaloric diet (DIO; 8‐weeks very low energy diet (VLED) + 4‐weeks weight maintenance diet) and 3. Hypocaloric diet and exercise (DEX; 8‐weeks VLED + 4‐weeks weight maintenance diet combined with exercise throughout the 12 weeks). Blood samples and fat biopsies were taken before and after the intervention.Results:
Weight loss was 3.5 kg in the EXO group and 12.3 kg in the DIO and DEX groups. VEGF‐A protein was non‐significantly reduced in the weight loss groups. ANG‐1 protein levels were significantly reduced 22‐25% after all three interventions (P < 0.01). The ANG‐1/ANG‐2 ratio was also decreased in all three groups (P < 0.05) by 27‐38%. ANGPTL‐4 was increased in the EXO group (15%, P < 0.05) and 9% (P < 0.05) in the DIO group. VEGF‐A, ANG‐1, and ANGPTL‐4 were all expressed in human AT, but only ANGPTL‐4 was influenced by the interventions.Conclusions:
Our data show that serum VEGF‐A, ANG‐1, ANG‐2, and ANGPTL‐4 levels are influenced by weight changes, indicating the involvement of these factors in the obese state. Moreover, it was found that weight loss generally was associated with a reduced angiogenic activity in the circulation. 相似文献3.

A possibility of the long-term modification of inborn behavioral features of different mice genotypes (C57B1/6 and BALB/c) by active immunization with dopamine-bovine serum albumin conjugate was investigated. Significant interstrain differences were found in the effects of dopamine antibodies on the open-field behavior and the content of neurotransmitters in the brain cortex and striatum. It was shown that the active immunization of mice to dopamine produces an increase in the functional activity of brain dopamine receptors. The extent, to which this increase is pronounced, is genotype-dependent. 相似文献

Dopaminergic brain system plays an important role in regulation of pain sensitivity. However, the data on participation of antidopamine antibodies in the development of neurogenic pain are absent. This work was aimed at the study of the role of antidopamine antibodies in the development of pain syndrome induced by the injury of nn. ischiadic and saphenous in rats. It was shown that after the nerve injury, the behavioral reaction such as autotomy (self-injury) appeared as a feature of the experimental neuropathic pain syndrome. It was originally established that the development of neuropathic pain syndrome induced by the injury of peripheral nerves was accompanied by induction of dopamine autoantibodies. It was also shown that immunization of the animals with conjugated dopamine-protein autigen resulted in aninerease of autidopamine antibody level and an amplification of the experimental neuropathic pain syndrome, i.e., decrease in the latency of the first autotomy, increase in expression of autotomies, and increase in the number of animals with late autotomies. 相似文献

Active immunization with dopamine conjugated with bovine serum albumin (DA-BSA) or BSA with complete Freund's adjuvant (CFA) partly suppressed the development of the MPTP-induced depressive syndrome in rats preventing the appearance of "behavioral despair" symptoms: increase in immobility time and higher index of depression in forced-swim test. In DA-BSA-immunized rats the content of DOPA, DA, HVA, NA, and 5-HN in caudate putamen and that of NA in the frontal cortex was increased, while in BSA-immunized rats the content of 5-HT in both brain areas and that of DOPAC in the frontal cortex was decreased both in rats with reduced depressive syndrome and in saline control as compared with intact animals a day after the last drug injection. In DA-BSA-immunized rats with reduced depressive syndrome the increase in DA and 5-HT content in caudate putamen was less expressed and DOPAC content was lower than in saline control. In BSA-immunized depressive rats DA content in the frontal cortex was also reduced as compared to control. 相似文献

Experiments on rabbits demonstrated that local electrocoagulation of the dorsal hyppocampus portions by means of the implanted electrodes caused reduction of the complementary and lysozyme activity of the blood serum, inhibited the development of Arthus' skin allergic-reaction, decreased the intensity of systemic anaphylaxis to the blood serum antigens, this being accompanied by a relative fall of the precipitating antibodies titres and a reduction of the vagus response of the heart to adrenaline. 相似文献

The final stage of endocytosis is fission of a thin membrane neck, or nanotube (NT), connecting cell membrane with a forming vesicle. We studied this process using a model system consisting of NT pulled out from a flat bilayer lipid membrane. Fission of NT was induced by an increase of osmotic pressure created by local application of a concentrated salt solution in the vicinity of NT. Superfusion of NT with distilled water instead of the concentrated salt solution led to the NT expansion. This observation demonstrates the reversibility of the NT expansion-compression process under the osmotic pressure. The overall picture of fission is similar to that described earlier for the NT fission with participation of dynamin GTPase. In both cases, in order for fission to occur, it is necessary to compress the NT to a critical radius. The critical radius estimated for the osmotic pressure-induced fission exceeds the value obtained for the fission occurring in the presence of the protein. Fission under osmotic pressure, akin the dynamin-promoted fission, proceeds without leaky defects. 相似文献

We combined three modern technologies of single base polymorphism detection in human genome: ligase detection reaction, rolling circle amplification and IMAGE hydro-gel microarrays. Polymorphism in target DNA was tested by selective ligation on microarray. Product of the ligase reaction was determined in microarray gel pads by rolling circle amplification. Two different methods were compared. In first, selective ligation of short oligonucleotides immobilized on microarray was used with subsequent amplification on preformed circle probe ("common circle"). The circle probe was designed especially for human genome research. In second variant, allele-specific padlock probes that may be circularized by selective ligation were immobilized on microarray. Polymorphism of codon 72 in human p53 gene was used as a biological model. It was shown that LDR/RCA on microarray is a quantitative reaction and gives high discrimination of alleles. Principles and perspectives of selective ligation and rolling circle amplification are being discussed. 相似文献
