Skin β-Endorphin Mediates Addiction to UV Light
UV light is an established carcinogen, yet evidence suggests that UV-seeking behavior has addictive features. Following UV exposure, epidermal keratinocytes synthesize proopiomelanocortin (POMC) that is processed to melanocyte-stimulating hormone, inducing tanning. We show that, in rodents, another POMC-derived peptide, β-endorphin, is coordinately synthesized in skin, elevating plasma levels a...
متن کاملβ-endorphin neuron transplantation
We summarize here our new discovery that the endogenous opioid peptide β-endorphin (BEP), by virtue of reducing body stress and maintaining active immune system, as well as, balancing the levels of pro-inflammatory and anti-inflammatory cytokines, destroys tumor cells and stops them from being transformed into metastatic cancer cells.

The physiological role of β-endorphin in porcine ovarian follicles
β-Endorphin-like immunoreactivity (β-END-LI) was measured by radioimmunoassay in porcine ovarian follicular fluid (FF) from small, medium and large follicles throughout the oestrous cycle. The concentration of β-END-LI in FF from small follicles collected on days 1–5 of the cycle was at least tenfold higher than in the fluid from any other follicles independently from their size and the period ...
متن کاملInfluence of training and competitive sessions on peripheral β-endorphin levels in training show jumping horses
AIM To investigate the effects of training sessions on circulating β-endorphin changes in sport horses before and after competition and to ascertain whether competition would affect this response. MATERIALS AND METHODS A total of 24 trained jumping horses were randomly assigned to one of two training groups: Group A (competing) and Group B (not competing). To determined plasma β-endorphin con...
