In this study we aimed toassess expression of four CTAs, namely [acrosinbinding protein (ACRBP), outer dense fiber4 (ODF4), Rhox homeobox family member 2(RHOXF2) and spermatogenesis associated 19(SPATA19)] in two breast cancer cell lines, 40invasive ductal carcinoma samples and theiradjacent normal tissues as well as fibroadenomasamples. The gene discussed is SPATA19; the disease is breast cancer.
