ABSTRACT
OBJECTIVE:
To evaluate the impact of GOLPH3 expression in cumulus granulosa cells on the outcomes of intracytoplasmic sperm injection (ICSI).METHODS:
A total of 119 women receiving ICSI due to male infertility at our center between April, 2012 and June, 2014 were enrolled in the study. Cumulus granulosa cells were collected from the women for detection of GOLPH3 expressions using immunocytochemistry, Western blotting, and real-time PCR. GOLPH3 expression rate was compared between women with and without clinical pregnancy following ICSI, and the associations of GOLPH3 expression with the laboratory indicators of ICSI outcomes were assessed.RESULTS:
Immunocytochemistry showed that GOLPH3 expression was located mainly in in the plasma of the cumulus granulosa cells. The rate and intensity of GOLPH3 expression in the cumulus granulosa cells differed significantly between women with and without clinical pregnancy following ICSI (P<0.05). GOLPH3 expression was found to positively correlate with the numbers of punctured follicles, grade III oocyte cumulus complex, ICSI oocytes, fertilized oocytes, cleavage, high quality embryos, blastocysts, high quality blastocysts, and frozen embryos (all P<0.01). The results of RTPCR and Western blotting revealed significant differences in GOLPH3 expressions at both the mRNA and protein levels in the cumulus granulosa cells between the pregnant and non-pregnant groups after ICSI (t=14.560, P=0.000). Western blot analysis revealed significant difference of GOLPH3 protein expression in cumulus granulosa cells between women with and without clinical pregnancy following ICSI.CONCLUSION:
GOLPH3 expression in the cumulus granulosa cells plays an important role in the development of oocytes and promotion of conception to affect the outcomes of ICSI.
