In this whole genome expression study on blood cell mRNA from ovarian cancer patients, only six genes, PDIA3, CYP1B1, LYAR, NOP14, NCALD, and MTSS1 showed a statistically significant difference in expression between subjects with tumors that were poorly differentiated vs. those who had moderately to well differentiated tumors. This evidence concerns the gene NOP14 and ovarian carcinoma.
