PTPRC and ovarian cancer: On the other side, the correlation analysis of multigene-derived data sets across ovarian cancer tissues revealed strong positive association between PTPRC/CD45, the classical immune cell marker, and APOBEC3 subfamily members such as A3C, A3D, A3H, and the prognostically relevant A3G as well as AID. Furthermore, although weaker, a positive association was observed with PAX5, the B-cell transcription factor.
