In GPL570 platform of GSE131978, by comparing RNA expression level between platinum "resistant" (PFI < 6 months) and platinum "sensitive" (PFI > 12 months) patients of high-grade serous ovarian carcinoma, CALD1 expression was up-regulated in platinum "resistant" and statistically significant (P = 0.03) (Fig. 14A). This evidence concerns the gene CALD1 and ovarian serous carcinoma.
