Biochem/physiol Actions

KC7F2 is a cell permeable potent HIF-1 pathway inhibitor. KC7F2 inhibits the activation of HIF-target genes such as carbonic anhydrase IX, matrix metalloproteinase 2 (MMP2), enolase 1, and endothelin 1. KC7F2 suppresses the protein accumulation of HIF-1? in cancer cell lines by inhibition of its protein synthesis at the translation level. KC7F2 is preferentially cytotoxicity to cancer cells, an effect that is increased in hypoxia.

Angiogenesis is an essential process involved in various physiological, including placentation, and pathological, including cancer and endometriosis, processes. Melatonin (MLT), a well‑known natural hormone secreted primarily in the pineal gland, is involved in regulating neoangiogenesis and inhibiting the development of

High-glucose level exerts deleterious effects on pancreatic β cells, but the mechanisms remain unclear. Calcium/calmodulin-dependent serine protein kinase (CASK) plays a vital role in neural development and release of neurotransmitters, and probably plays a role in the anchoring of insulin

Tumor hypoxia induces hypoxia-inducible factor-1α (HIF1α), which can influence tumorigenesis and metastasis. We evaluated the expression of HIF1α and the effect of HIF1α inhibitors in adenoid cystic carcinoma (ACC). HIF1α expression was demonstrated in ACC cell lines (ACC2 and ACCM).

The aim of this study was to observe the effects of HIF-1α activation on myocardial I/R in diabetes. Diabetes was induced in an experimental rat model, and regulators of HIF-1α including KC7F2, deferoxamine and ginsenoside Rg1 were administered to observe

Endometrial cancer stem cells (ECSCs) are stem-like cells endowed with self-renewal and differentiation abilities, and these cells are essential for cancer progression in endometrial cancer (EC). As hallmarks of the tumour microenvironment (TME), hypoxia and hypoxia-inducing factors (HIFs) give rise
