1 RESULTS: CCND1, c-Fos and c-Jun mRNA levels were all significantly increased by treatment with progesterone in QGP-1 cells with PRB expression compared with PRA-transfected cells (p = 0.02, p = 0.007 and p = 0.001, respectively). Progesterone RB transcriptional corepressor 1 Homo sapiens
2 The proliferative activity of QGP-1 cells with PRB expression was also significantly stimulated by the administration of progesterone (p = 0.008). Progesterone RB transcriptional corepressor 1 Homo sapiens
3 CONCLUSION: The results of the present study demonstrate that PRA could play an inhibitory role in the cell proliferation of PNETs, possibly by inhibiting PRB-mediated signals in the presence of progesterone, which could result in decreased CCND1 expression. Progesterone RB transcriptional corepressor 1 Homo sapiens
