Web29 de nov. de 2013 · As a major transcriptional activator responsible for cellular response to hypoxia, the hypoxia-inducible factor (HIF)-1 is a heterodimer composed of HIF-1α and HIF-1β subunits. HIF-1β is constitutively expressed in the nucleus and its levels are unaffected by oxygenation conditions, whereas HIF-1α is tightly regulated by O 2 tension [21].

Web23 de abr. de 2015 · We therefore proposed that mTORC1 drives HIF-1α synthesis in a multifaceted manner through 4E-BP1/eIF4E, S6K1 and STAT3. Interestingly, we … Web6 de fev. de 2015 · We found that T2A inhibited angiogenesis and tumor growth through repression of HIF-1α at the translation level. Inhibition of the transcriptional activity of HIF-1 led to the down-regulation of VEGF. We further showed that the interruption of mTOR/p70S6K/4E-BP1 signaling pathway was involved in the inhibition of HIF-1a … Web28 de nov. de 2024 · TME中基质细胞的代谢产物无论作用于肿瘤还是其他基质细胞都能影响肿瘤发展,这提示我们在肿瘤治疗过程中需要留意到除肿瘤和免疫细胞之外的细胞群。. 在致癌因素影响下,肿瘤微环境(TME)中各类细胞发生代谢改变,为肿瘤发生发展创造有利条件。. 不仅是 ... immortals fenyx rising family emergency guide
