Human (visceral) obesity is associated with alterations hypothalamus-pituitary-adrenal (HPA) axis functioning. It is however not completely clear whether the HPA axis is causally or co-incidentally related to (visceral) obesity. This review summarizes supporting data of an involvement of the HPA axis in the development of (visceral) obesity. First, several DNA polymorphisms related to HPA axis ...

PURPOSE OF REVIEW Past studies in humans and animals have shown that low blood glucose concentrations due to fasting negatively interfere with the ability to mount a hypothalamus-pituitary-adrenal (HPA) axis response to psychological stress or to pharmacological activation, respectively. This contradicts the classical view of the proposed primary glucocorticoid function of providing the individ...

Burnout is presumed to be the result of chronic stress, and chronic stress is known to affect the HPA-axis. To date, studies on HPA-axis functioning in burnout have showed inconsistent results. In the present study, a large sample (n=74) of clinically diagnosed burnout individuals, mostly on sick-leave, were included and compared with 35 healthy controls. Salivary cortisol was sampled on 2 days...

Limited digestion of superhelical (form I) PM2 DNA by venom phosphodiesterase yields unit length linear (form III) molecules plus a series of discrete fragments. The positions of eight of these fragments on the genome map were determined with the use of restriction endonucleases Hpa II and HindIII. These positions were compared with the locations of the eight early denaturation regions in form ...

More than 50% of mammalian genes are associated with CpG islands and thus they serve as a good gene marker. We have devised a simple method to scan large pieces of native or cloned genomic DNA for CpG islands. The method is based on the presence of multiple Hpa II and Hha I sites in CpG islands, at a frequency 30 times higher than in the rest of the genome. The steps include complete digestion ...

In the present work we have studied the effects of exogenously applied methyl ester of jasmonic acid (MeJA) and benzyladenine (BA) on rRNA gene expression in the model system of excised marrow cotyledons (Cucurbita pepo L. zucchini). Treatment of cotyledons with BA or MeJA resulted in a 2-fold increase and a 25–30% decrease in the endogenous nuclear RNA polymerase I activity, respectively. The ...

DNA methylation as epigenetic mark plays a key role in normal differential and developmental processes as well as in dynamic gene regulation at the genomic level. To assess DNA methylation pattern in different developmental stages of Aeluropus littoralis, methylation sensitive amplified polymorphism (MSAP) was used. Methylation and demethylation status at the CCGG recognition site were...

introduction: different mechanisms are involved in stress induced analgesia (sia) and hyperalgesia (sih). repeated stress induces development of tolerance to sia. the role of hpa axis and gs signaling pathway in these effects are investigated in the current study. methods: forced swim stress (5 min/day) in water (20±1 ºc) was employed to adult male wistar rats (200-250 g). the nociceptive thres...

objective(s) the mechanism(s) by which antidepressants regulate the hypothalamic-pituitary-adrenal (hpa) axis remain elusive. the endocannabinoid system (ecbs) which exhibits antidepressant potential, appears to regulate the hpa axis activity. therefore, we aimed to investigate the role of the ecbs in the action of doxepin including its effect on the hpa axis. materials and methods male wistar ...

Platelets share antigens with other cells such as ABH and HLA class I antigens, but also express specific antigens. Platelet specific antigens are identified according to a nomenclature devised by the International Society of Blood Transfusion and are referred to as Human Platelet Antigens (HPA). These include glycoproteins expressed on platelet surfaces such as GPIIb/IIIa, the von Willebrand f...
