GREM1, HAS2 and PTGS2 Gene Expression Following the in Vitro Maturation (IVM)

In this study, we will follow up the normal and POR women. The discarded product - cumulus cell will be used in this study for evaluation following the standard IVF cumulus-oocyte-complex denudation. We will develop the In-Vitro Model to assess the expression of GREM1, HAS2, and PTGS2 in normal and POR women first. Subsequently, these gene expressions will be reassessed again via clinical model using IVF-IVM cumulus cell comparing the both groups to elucidate the modifying of oocytes quality following IVM. The cumulus cell RNA will be extracted,and the cDNA will be synthesized and quantitated. The RT-PCR standard curves will be produced, and the concentration range of these genes will be generated and quantified. The OQ, embryo morphology scoring, fertilization rates, and live birth rates will be recorded and compared. We anticipate a higher gene expression associated with good OQ thus better fertilization and live birth rate. Therefore, this research will understand the impact of IVM in oocytes competency, aiming to improve the fertility rate among POR women in Malaysia.
