Glucagon-like peptide-2 (GLP-2) is secreted from enteroendocrine L-type cells of the gut and also released preproglucagonergic (PPG) neurons in nucleus tractus solitarius (NTS) adjacent medial reticular brain stem. The NTS express GLP-2, send extensive projections to hypothalamus. Recent studies show that intracerebroventricular administration GLP-2 significantly suppresses food intake animals ...

Electroacupuncture (EA) is a modified form of acupuncture that utilizes electrical stimulation. We previously showed that EA stimulated rats were divided into responders that were sensitive to EA and non-responders that were insensitive to EA based on the tail flick latency (TFL) test. The dopamine beta-hydroxylase (DBH) gene was more abundantly expressed in the hypothalamus of responder rats t...

In a previous study, we provided evidence for the presence in hypothalamus and Brockmann bodies (BB) of rainbow trout Oncorhynchus mykiss of sensing systems responding to changes in levels of oleic acid (long-chain fatty acid, LCFA) or octanoic acid (medium-chain fatty acid, MCFA). Since those effects could be attributed to an indirect effect, in the present study, we evaluated in vitro if hypo...

Leptin is a circulating molecule for the regulation of food intake and body weight suggested to be mediated in the hypothalamus via Ob-Rb receptor, which activates Janus kinase-signal transducer and activator of transcription (STAT) pathways. Although leptin receptors exist in many regions of the brain, there have been few in vivo functional studies of leptin's target site other than the hypoth...

The fetal genome regulates maternal physiology and behavior via its placenta, which produces hormones that act on the maternal hypothalamus. At the same time, the fetus itself develops a hypothalamus. In this study we show that many of the genes that regulate placental development also regulate the developing hypothalamus, and in mouse the coexpression of these genes is particularly high on emb...

objective: orexin is a hypothalamic orexigenic neuropeptide, which third cerebral injection of it mainly exerts inhibitory effects on reproductive functions. it increases significantly the aromatase (cyp19) gene expression in the hypothalamus of male rats. aromatase is an enzyme which converts androgens to estradiol in the hypothalamus of rats. prenatal or neonatal exposure of females to testos...
