Phenotype disruption of umbilical cord derived MSC by cyclic mechanical stretch and hyperoxia mediated by p21

本研究探讨了脐带来源的间充质干细胞(UC-MSC)在机械拉伸(CMS)和高氧(HOX)条件下的表型变化及其对细胞生存的影响。结果显示,CMS和HOX导致UC-MSC的增殖和细胞活力下降,且p21的积累在细胞衰老中起到关键作用。研究表明,虽然这些表型变化在一定条件下是可逆的,但长时间的强刺激会导致不可逆的生长抑制。这些发现为UC-MSC在临床应用中的潜力提供了新的见解,并强调了未来研究的必要性。

Aloesin activates Nrf2 signaling to attenuate obesity-associated oxidative stress and hepatic steatosis in high-fat diet-fed rats

Aloesin, a compound derived from Aloe vera, has shown promising hepatoprotective effects against non-alcoholic fatty liver disease (NAFLD) in a rat model induced by a high-fat diet. The study highlights its ability to activate Nrf2 signaling, which mitigates oxidative stress and inflammation, leading to improved metabolic parameters and liver health. These findings suggest that aloesin could be a valuable therapeutic agent for NAFLD, warranting further exploration in clinical settings.
