Hypothalamic leptin signaling plays a central role in maintaining body weight homeostasis. Here, we show that clusterin/ApoJ, recently identified as an anorexigenic neuropeptide, is an important regulator in the hypothalamic leptin signaling pathway. Coadministration of clusterin potentiates the anorexigenic effect

Autophagy, an innate cellular destructive mechanism, plays crucial roles in plant development and responses to stress. Autophagy is known to be stimulated or suppressed by multiple molecular processes, but the role of phytohormone signaling in autophagy is unclear. Here, we

We have previously shown that in neonatal rats subjected to hypoxia-ischemia (HI) rapamycin administration increases autophagy, decreases apoptosis and significantly reduces brain damage. After HI, when autophagy is blocked neuronal cells rapidly progress toward necrotic cell death. The present study
