Web16 nov. 2008 · Likewise, mTOR inhibition by RAD001 completely blocked HIF-1α and pAKT in REH cells. Importantly, REH cells co-cultured with MSC under hypoxia/high glucose environment exhibited significantly lower apoptotic rates (p=0.02) and growth inhibition (p=0.002) in response to vincristine, and these effects were reversed by mTOR blockade … REDD1 is required for inhibition of mTORC1 activity under hypoxia. …

Web13 iun. 2024 · It is known that PI3K/Akt/mTOR signalling axis is activated under hypoxic condition, and its activation is required for the hypoxic stabilization of HIF-1α . PI3K is an important upstream regulator of hypoxia-induced Akt activation. WebThe reduction in phospho-p70S6K levels and elevation of HIF-1α, Slug and LDHA levels represent the molecular changes induced by hypoxic stress. 42–45 Accordingly, we …
WebIt was observed that bcr-abl translation was severely halted in hypoxia, rendering TKIs ineffective. We found that the mechanism by which bcr-abl protein levels were being suppressed in hypoxia was through the mTOR pathway, specifically via ribosomal protein S6 (RPS6). This information is vital to the improvement of CML treatments, as it can be ... Web9 ian. 2024 · Earlier studies found that hypoxia activated mTOR signaling and resulted in HIF-1α stabilization , angiogenesis , and proliferation , meanwhile hypoxia appeared to inhibit mTOR signaling pathway, as demonstrated by inactivation of the S6K1 and 4E-BP1 . The disruption of skin integrity with the loss of epithelial cells continuity results in the ...
Web1 feb. 2016 · Using HepG2 cells as a model for fetal hepatocytes (16, 32– 35), we tested the hypothesis that IGFBP-1 hyperphosphorylation in response to hypoxia is mediated by mTOR inhibition ().We applied pharmacological and RNA interference (RNAi) approaches to inhibit and/or activate mTORC1/mTORC2 in HepG2 cells cultured under normoxic and … Web7 sept. 2024 · Obviously, mTOR is a part of the phosphatidylinositol 3-kinase/Akt/mTOR signaling pathway and is also related to tumor angiogenesis. This pathway is also becoming a key regulator of hypoxia and growth factor-mediated tumor hypoxia-induced expression. In addition, mTOR is very conserved and widely expressed, including in endothelial cells.
WebPrevious studies have shown that HIF-1α is subjected to regulation by the PI3K/Akt/mTOR ( 20, 25 ) and PI3K/Akt/FRAP ( 26) signaling pathways. The p-Akt and HIF-1α protein levels were shown to increase in response to hypoxia in human mesenchymal stem cells. Moreover, p-Akt expression peaked earlier than that of HIF-1α.
WebThe development of hypoxia-targeting nanomaterials – aimed at enhancing the effect of radiotherapy by electrical or heat effects and at modulating hypoxia in the tumor microenvironment – is a promising strategy to address this issue. ...
