ABSTRACT Nanozymes have attracted considerable attention in cancer therapy due to their adjustable enzyme activity and high catalytic efficiency. However, they still face a major challenge from tumor metastasis. In this work, endogenous/exogenous dual‐responsive bimetallic hollow PdRu (termed HPdRu) nanozymes were prepared.

The association between the antioxidant property and ROS system in murine corneal epithelial progenitor cells [PDF]
目的:活性氧(ROS)是体内产生的一种高活性分子,低浓度可以调节细胞代谢,基因转录和磷酸酶的活性,高浓度则会导致氧化损伤。目前,有关干细胞自身特性的研究越来越受到学者们的重视,但既往文献中关于干细胞对氧化应激反应以及应激条件下细胞内相关酶活性的变化规律却很少报道。本课题聚焦于,在过氧化氢(H2O2)诱导的氧化应激条件下,活性氧生成关键因子NOX4和抗氧化酶核转录因子NRF2在小鼠角膜上皮祖细胞(TKE2)和成熟的小鼠角膜上皮细胞(MCE)中的不同作用及相关机制。 方法:利用小鼠角膜上皮祖细胞(TKE2 ...
