BOP1 and cancer: Among them, several ERGs were repeatedly up- or down-regulated in several cancer types; the primary genes were CHRAC1, PHC3, and BOP1, which were among the top 10 most up-regulated ERGs recurrently observed in 18, 9, and 7, respectively, out of 33 cancer types (Fig. 3A, only the top 5 ERGs are shown; see Supplemental Table S3 for the top 10 ERGs).
