The same authors reported that PAR/JTB expression was upregulated in all studied prostatic carcinoma cell lines compared with normal prostatic tissue, in androgen-resistant prostate cancer cell lines in comparison with androgen-sensitive prostate cells, in MCF7 and T47D BC cell lines, as well as in all the primary breast tumors studied compared to their normal counterparts. The gene discussed is JTB; the disease is prostate carcinoma.
