Alteration of gene expression in human cumulus cells as a potential indicator of oocyte aneuploidy

Abstract

In the current study, SPSB2 and TP53I3 exhibited highly significant differences in their expression between CCs of normal and chromosomally abnormal oocytes. SPSB2 is involved in intracellular signalling and homeostasis, whereas TP53I3 regulates carbohydrate metabolism and apoptosis. We speculate that both these genes might have the potential to serve as non-invasive markers of oocyte aneuploidy.
