Web6 de out. de 2014 · In contrast, we showed that ROS up-regulates HIF-1, which contributes to ROS-induced longevity by amplifying ROS levels through positive feedback. We further demonstrated the functional significance of this feedback regulation in immunity by showing that ROS enhances pathogen resistance in an AMPK- and HIF-1–dependent manner. WebIt is possible to speculate that this ROS action on HIF1α stabilization is related to the antioxidant response (increase on antioxidant defense) after ROS exposure or redox stress. WebTaken together, the results presented in Fig. 5 suggest that increased ROS levels trigger HIF-1 signaling leading to BCSC enrichment. Fig. 5. Paclitaxel-induced ROS is required for HIF-1α expression and BCSC enrichment.
