Compared to the non-cancerous ovary, PGRMC1 was present in greater abundance in clear cell carcinoma (Figure 1A), endometroid carcinoma (Figure 1B), and papillary serous cystadenocarcinomas with increasing staining intensity as these cancers progress from stage IIB (Figure 1C) to stage IIIC (Figure 1D) [41]. This evidence concerns the gene PGRMC1 and cancer.
