VEGFA and ovarian carcinoma: Our previous studies have indicated that the loss of expression of miR-126 contributes to the abnormal VEGF-A accumulation and subsequent unchecked cell invasion and cell proliferation in epithelial ovarian cancer.[15] Interesting, in this study, we found that miR-126 was upregulated in the patients with resistant or refractory relapse (PFI < 6 months) compare to patients with partially sensitive or sensitive relapse (PFI > 6 months).
