MiR-93 Inhibits Trophoblast Cell Proliferation and Promotes Cell Apoptosis by Targeting BCL2L2 in Recurrent Spontaneous Abortion.

Recurrent spontaneous abortion (RSA) is a common health problem that affects 1-5% of women in reproductive age. Plenty of studies have indicated that microRNAs (miRNAs) are involved in the occurrence of miscarriage. MiR-93 has a wide range of functions in mammalian tissues and plays an important role in many diseases especially for cancers.

[Association study between a polymorphism of aldosterone synthetase gene and the pathogenesis of polycystic ovary syndrome].

Objective: To investigate the relationship between -344T polymorphism in aldosterone synthetase (CYP11B2) gene promoter region and the pathogenesis of polycystic ovary syndrome (PCOS).

Methods: Ninety two patients with PCOS and controls were genotyped according to the fragment length (273 bp and or 202 bp) of CYP11B2 gene promoter by the technique of polymerase chain reaction-restriction fragment length polymorphism. The levels of luteinizing hormone, follicular stimulating hormone, estrodiol, progesterone, prolactin, testosterone, plasma renin activity (PRA), plasma angiotensin II (PANG II) and aldosterone in the basal state were also determined.
