Expression of H19 imprinted genes in the villus tissues of women with spontaneous abortion / 西安交通大学学报(医学版)

ABSTRACT

Objective To investigate the expression of H19 imprinted genes in the villus tissues of women with spontaneous abortion.Methods Reverse transcription-polymerse chain reaction method(RT-PCR) was employed to detect H19 imprinted genes allele-specific expression levels of the villus tissues extracted from 45 cases of spontaneous abortion and 30 cases of normal pregnancy.Results Nineteen cases of 21 heterozygous cases in spontaneous abortion samples showed billelic expression of H19(19/21),whereas no billelic expression was found in the normal pregnancy samples(0/13)(P
