Impact of Ashwagandha Extracts and Purified Withanolides on Hypoxia and Autophagy Oxidative anxiety in skeletal muscle has been shown to regulate muscle differentiation and functional traits. With low to moderate levels of oxidative pressure, p53 is involved in activating pathways that prolong the time for cells to repair by activating cell cycle arrest and autophagy and enhancing cell survival. Having said that, with greater levels of anxiety intensity and duration (such as irradiation, hypoxia, and oxidizing agents) it causes apoptosis, and hence, p53 acts as a threshold regulator of cellular homeostasis . Hypoxia-inducible transcription element (HIF-1) is definitely the master regulator of hypoxia signaling. Deregulated HIF-1 signaling has been associated with numerous pathological conditions such as cancers and brain- and muscle-disorders. Whereas under normoxia conditions, HIF-1 undergoes hydroxylation and degradation by the proteasome-mediated degradation pathway, hypoxia prevents HIF-1 hydroxylation and degradation . Because of this, HIF-1 accumulates, translocates in to the nucleus, dimerizes with HIF-1, and transactivates numerous effector proteins involved in cancer cell migration and angiogenesis. We investigated the effect of Ashwagandha extracts along with the purified withanolides on hypoxia responsive element (HRE)-luciferase activity. Cells transfected with plasmid expressing HRE-driven luciferase have been subjected to control and Ashwagandha extracts/bioactive compounds-supplemented medium. As shown in Figure 7A, HRE promoterdriven luciferase assay showed a stronger boost in cells treated with extracts #3, #7, and #11, which contained a relatively high content of Wi-A as in comparison to other extracts and Wi-N. This result was in line with all the data obtained from the recovery of heat-induced folding of luciferase. Detection of HIF-1 protein by Western blotting utilizing anti-HIF-1 antibody also exhibited an in.
