Oxidative stress, redox signaling, and autophagy: cell death versus survival.
SIGNIFICANCE The molecular machinery regulating autophagy has started becoming elucidated, and a number of studies have undertaken the task to determine the role of autophagy in cell fate determination within the context of human disease progression. Oxidative stress and redox signaling are also largely involved in the etiology of human diseases, where both survival and cell death signaling cas...
متن کاملHypoxia-induced autophagy promotes tumor cell survival and adaptation to antiangiogenic treatment in glioblastoma.
Antiangiogenic therapy leads to devascularization that limits tumor growth. However, the benefits of angiogenesis inhibitors are typically transient and resistance often develops. In this study, we explored the hypothesis that hypoxia caused by antiangiogenic therapy induces tumor cell autophagy as a cytoprotective adaptive response, thereby promoting treatment resistance. Hypoxia-induced autop...
متن کاملLyn Facilitates Glioblastoma Cell Survival under Conditions of Nutrient Deprivation by Promoting Autophagy
Members of the Src family kinases (SFK) can modulate diverse cellular processes, including division, death and survival, but their role in autophagy has been minimally explored. Here, we investigated the roles of Lyn, a SFK, in promoting the survival of human glioblastoma tumor (GBM) cells in vitro and in vivo using lentiviral vector-mediated expression of constitutively-active Lyn (CA-Lyn) or ...
متن کاملCell-mediated autophagy promotes cancer cell survival.
Immune effector cells integrate signals that define the nature and magnitude of the subsequent response. Experimental measures for immune cell-mediated lysis of tumors or virally infected targets rely on average responses of permeability or apoptotic changes within a population of targets. Here, we examined individual target cells following interaction with lymphoid effectors. We found that hum...
متن کاملMitochondrial dysfunction activates the AMPK signaling and autophagy to promote cell survival
Autophagy is a cellular self-eating process essential for stress response and maintaining tissue homeostasis by lysosomal degradation of unwanted or damaged proteins and organelles. Here, we show that cells with defective mitochondria induce autophagy to promote cell survival through activating the AMPK pathway. Loss of mitochondrial complex III protein cytochrome b activates the AMPK signaling...
