MOLECULAR CHARACTERIZATION OF UTERINE LEIOMYOMA ACCORDINGTO EXPRESSION OF GENES OF STEROID RECEPTORS, STS, SULT AND PTEN
Leiomyoma is one of the most common benign tumors of the female reproductive system. As this pathology in most cases is hormone
dependent, we determined the level of gene expression of steroid receptors ERs, PR, estrogen sulfotransferase SULT1E1, STS steroid
sulphatase and tyrosine phosphatase PTEN in myoma nodes in 33 women using Real-time RT-PCR. A significant increase in the level of
mRNA of the ERα, ERβ, PgR, and the PTEN gene in samples from proliferative and non-proliferative uterine leiomyoma, as well as the
decrease in the expression of genes STS, PTEN and PgR in samples of myoma associated with hyperplasia and malignant uterine have been
identified.
