ATP6V1B1 and ovarian carcinoma: We assessed the ovarian cancer enrichment and overall expression level in TCGA OV HiSeq versus PANCAN normalized expression plots and observed generally high expression of transcripts encoding the identified MAPs and several ovary-enriched genes (PANCAN Expresson > 0) including MSLN, MUC16, PAX8, KLK8, and ATP6V1B1 (Fig. 5b left side plots, red symbols).
