Opracowanie modelu badawczego in vitro do analiz wpływu stanu ketozy na angiogenezę nowotworową; Miniatura 8 (2024/08/X/NZ3/00599) (dataset)

Abstract

As part of the Miniatura 8 research project, the effect of the ketosis state on tumour-associated angiogenesis was investigated. An in vitro model reflecting the conditions during ketogenic diet was developed, and the effects of glucose deprivation and ketone bodies were compared in tumour (TECs) and normal (NECs) endothelial cells. The studies were performed using the HMEC-1 cell line, in which a tumour endothelial cell model was generated under hypoxic conditions and in the presence of cancer cell-secreted pro-angiogenic factors. The expression of ketone body transporters and ketolytic enzymes was analysed at both the mRNA and protein levels in NECs and TECs, and their ability to metabolise ketone bodies was compared. In further experiments, the effect of ketone bodies on endothelial cell viability and the secretion of pro-angiogenic factors by colorectal cancer cell lines were evaluated.
