ADAR1 expression in different cancer cell lines and its change under heat shock.

Adenosine deaminase acting on RNA 1 (ADAR1) plays an essential role in the development of malignancies by modifying the expression of different oncogenes. ADAR1 presents three distinct activities: adenosine-to-inosine RNA editing, modulating IFN pathways, and response to cellular stress factors. Following stressors such as heat shock, ADAR1p110 isoform relocates from the nucleus to the cytoplasm, where it suppresses RNA degradation which leads to the arrest of apoptosis and cell survival.

The GG genotype of the -152 G/A vascular endothelial growth factor (VEGF) polymorphism predisposes to hypertension-related chronic kidney disease.

Our purpose was to determine whether the VEGF -152 G/A polymorphism could be associated with chronic kidney disease and endothelial dysfunction in hypertensive patients. There were 100 healthy volunteers enrolled into the control group. The group of patients was constituted by 99 consecutively admitted hypertensive patients referred to our Institution by their general practitioner.

Vascular endothelial growth factor polymorphism (-460 T/C) is related to hypertension-associated chronic kidney disease.

Our aim was to characterize the endothelial progenitor cells (EPCs) in normotensive controls and treated hypertensive individuals within the vascular endothelial growth factor (VEGF) -460 C/T polymorphism as well as to investigate whether this polymorphism predisposes to hypertension-related chronic kidney disease. The hypertensive patients bearing the TT genotype had the highest levels of immature EPC with the following phenotypes: CD34(+), CD34(+)CD45(dim), CD34(+)CD133(+)CD45(dim). The study showed the estimated glomerular filtration rate values significantly lower and creatinine and BUN parameters higher among the TT hypertensive patients.

The GA genotype of the -1154 G/A (rs1570360) vascular endothelial growth factor (VEGF) is protective against hypertension-related chronic kidney disease incidence.

Vascular endothelial growth factor (VEGF) is a highly specific mitogen with angiogenic and vascular permeability activities for endothelial cells. VEGF participates in maintaining the renal vasculature integrity. There is no doubt that hypertension accelerates progression to renal dysfunction, resulting in chronic kidney disease (CKD).
