The analysis of methylation of DNA promoter of SFRP2 gene in patients with hyperplastic processes of the endometrium.

Unlabelled: The hyperplastic processes of the endometrium can arise not only against the background of excessive influence of estrogen, but also against the background of epigenetic damages that affect apoptosis, cell proliferation, differentiation, and adhesion, and DNA reparation. The aim of our study was to investigate and analyze the status of methylation of the promoter of SFRP2 gene in patients with hyperplastic processes of the endometrium.

Materials And Methods: The study groups were the following: I - patients with endometrial hyperplasia (EH, n = 9); II - patients with endometrial intraepithelial neoplasia (EIN, n = 10), III - control groups: 1) with endometrial cancer (EC, n = 4), and 2) healthy women (n = 4).

[Effect of ascorbic acid on the renal transport of endogenous nitrates and nitrites in humans].

Effect of ascorbic acid on the renal excretion of endogenous nitrates and nitrites under aqueous-salt load was studied in practically healthy females. The administration of ascorbic acid in a dose of 10 mg/kg body weight under these conditions favored a decrease in the renal excretion of endogenous nitrates due to modulation of their renal clearance mechanism.
