WebHypoxia-inducible factor. Hypoxia-inducible factors ( HIFs) are transcription factors that respond to decreases in available oxygen in the cellular environment, or hypoxia. [1] [2] They are only present in parahoxozoan animals. [3] Web1 de jun. de 2024 · Background Although many studies have revealed essential roles of HIF1A (hypoxia inducible factor 1 subunit alpha) in regulating various pathways associated with cancer development, a systematic investigation of associations of HIF1A expression with tumor immunity, the tumor microenvironment and other tumor phenotypes in pan …

Web2 de out. de 2024 · Interestingly, TAMs within the microenvironment of breast cancers upregulate aerobic glycolysis of tumour cells through shuttling of extracellular vesicles containing lncRNA HIF-1α-stabilising non-coding RNA (HISLA), which promotes HIF-1α stabilisation by preventing the interaction between HIF-1α and the PHD enzymes (Chen … Web1 de nov. de 2024 · Methods. We performed studies with Kras LSL-G12D/+;Trp53 LSL-R172H/+;Pdx1-Cre (KPC) mice, KPC mice with labeled pancreatic epithelial cells (EKPC), and EKPC mice with pancreas-specific depletion of HIF1A.Pancreatic and other tissues were collected and analyzed by histology and immunohistochemistry.

Loss of HIF1A From Pancreatic Cancer Cells Increases Expression of ...
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.
