Here, we show that the ERα-expressing breast cancer cells MCF-7, CAMA-1, and T47D are less sensitive to antiestrogens when hypoxic. Furthermore, protein and mRNA levels of HIF2α/HIF2A were increased in a panel of antiestrogenresistant

Web6 de mar. de 2024 · HIF1-α and HIF2-α are proposed to contribute to the functions of osteoblasts and osteoclasts in bone homeostasis [97,98], which can potentially be attributed to the hypoxic condition in bone microenvironments, such as the endosteal areas of bone medullary cavity and the epiphyseal growth plate . WebLoss of pVHL leads the inappropriate accumulation of active HIF1 and HIF2. HIF2 drives clear cell renal carcinogenesis, and drugs that inhibit the HIF2-responsive gene product VEGF are now cornerstones of kidney cancer therapy.

Web50 used to assess whether HIF2 inhibition improves response to immune checkpoint 51 blockade. 52 53 Results. CAF-specific deletion of HIF2, but not HIF1, suppressed PDAC tumor 54 progression and growth, and improved survival of mice by 50% (n = 21-23 55 mice/group, Log-rank P = 0.0009). Deletion of CAF-HIF2 modestly reduced WebHIF2, but not HIF1, is both necessary and sufficient to prevent radiation-induced GI toxicity and death. Increased vascular endothelial growth factor (VEGF) expression contributes to the protective effects of HIF2, because inhibition of VEGF function reversed the radioprotection and radiomitigation afforded by DMOG.
