Web1 de mai. de 2024 · Tumor hypoxia is a common clinical condition caused by inadequate oxygen supply at the tissue level, resulting in altered metabolism and augmented metastatic potential of cancer cells [4].In response to hypoxia, dynamic changes of the tumor microenvironment (TME) allow cancer cells to adapt their growth and metabolism to low … HIF1A is overexpressed in many human cancers. HIF1A overexpression is heavily implicated in promoting tumor growth and metastasis through its role in initiating angiogenesis and regulating cellular metabolism to overcome hypoxia. Hypoxia promotes apoptosis in both normal and tumor cells. However, hypoxic conditions in tumor microenvironment especially, along with accumulation of genetic alternations often contribute to HIF1A overexpression.
