Web1 de mar. de 2001 · Abstract. Hypoxia inducible factor 1a and 2a (HIF-1a and HIF-2a) are key proteins regulating cellular response to hypoxia. Because the efficacy of photodynamic therapy (PDT) is dependent on the presence of oxygen, the assessment of HIF-1a and HIF-2a expression may be of value in predicting clinical response to PDT. Using recently … Web22 de jan. de 2024 · HIF is a transcription factor which regulates the expression of genes involved in adjusting mechanisms to hypoxia such as angiogenesis or apoptosis as well as tumor growth, invasion, and met … The HIF signaling pathway is activated by tumor-induced hypoxia or by inactivating mutations of the VHL gene.
