产品描述 Description

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].

Humanin (HN) 是一种天然的短线粒体多肽，具有抗细胞凋亡和神经保护作用[2]。 Humanin 保护细胞免受各种疾病的侵害，包括氧化应激和各种刺激引起的细胞毒性[3]，对胰腺、大脑、睾丸和心脏具有广谱活性[4] . Humanin 及其类似物可作为神经保护和神经退行性疾病的良好治疗靶点[1]。

Humanin 可提高细胞活力。 HN 降低了亚二倍体 KGN 细胞的百分比以及凋亡 KGN 细胞的百分比。 Humanin 可被视为该肿瘤细胞系的促存活因子[5]。 Humanin 可能参与 HLEC 对氧化应激的反应，并且 HN 表达在氧化应激条件下显着上调。此外，外源性 HN 可降低细胞内 ROS 含量和线粒体损伤，并增强线粒体生物合成；然而，这种保护在内源性 Humanin 敲低细胞模型中丢失了[6]。 Humanin 与其受体（CNTFR、WSX-1 和 gp130）的相互作用可通过增加 STAT3 表达激活 STAT3 信号通路，从而导致胰腺中 β 细胞存活率增加[9].

Humanin 在体外人类细胞培养模型中具有神经保护作用，足以改善老年小鼠体内的认知能力[8]。为了解 Humanin 对脑功能的影响，S14G-HN 对地西泮 (DZP) 诱导的小鼠记忆障碍和焦虑的影响使用物体识别测试和零迷宫测试。腹膜内注射 S14G-HN 可逆转 DZP 诱导的记忆缺陷，而在焦虑的行为标志物中未观察到显着变化。在这两项测试中，S14G-护脑素对运动活动均无影响，表明 S14G-HN 不影响身体机能或动机[7]。
