Humanin (HN) is a natural short mitochondrial polypeptide with antiapoptotic and neuroprotective effects[2]. Humanin protect cells against various diseases, including oxidative stress and cytotoxicity induced by various stimuli[3] with broad-spectrum activity on pancreas, brain, testis, and heart[4]. Humanin and its analogs could be used as good therapeutic targets against neuroprotective and neurodegenerative diseases[1].
Humanin increased cell viability. HN decreased the percentage of hypodiploid KGN cells as well as the percentage of apoptotic KGN cells. Humanin could be considered a pro-survival factor in this tumor cell line[5]. Humanin may be involved in the response of HLECs to oxidative stress, and that HN expression was significantly upregulated under oxidative stress conditions. Furthermore, exogenous HN reduced intracellular ROS content and mitochondrial damage, and enhanced mitochondrial biosynthesis; however, this protection was lost in an endogenous Humanin knockdown cell model[6]. The interaction of Humanin and its receptors (CNTFR, WSX-1, and gp130) could activate the STAT3 signaling pathway via an increase in STAT3 expression and consequently lead to the increase of beta cell survival in the pancreas[9].
Humanin administration has neuroprotective effects in vitro in human cell culture models and is sufficient to improve cognition in vivo in aged mice[8]. To understand the effects of Humanin on brain function, The effect of S14G-HN on diazepam (DZP)-induced memory impairment and anxiety in mice using the object recognition test and zero-maze test. Intraperitoneal injection of S14G-HN reversed the DZP-induced memory deficit, whereas no significant change was observed in behavioral markers of anxiety. S14G- Humanin had no effect on locomotor activity in either test, indicating that S14G-HN did not affect physical functioning or motivation[7].
