TUMOR NECROSIS FACTOR-α REPRESSES ANDROGEN SENSITIVITY IN THE LNCaP PROSTATE CANCER CELL LINE

Abstract

TNFalpha is present and inducible in prostate cancer cells and short-term TNFalpha diminishes androgen-sensitivity in LNCaP cells through down-regulation of AR protein and mRNA levels. These results suggest that TNFalpha may play a role in the initiation of an androgen-independent state in prostate cancer through its ability to inhibit AR sensitivity in prostate cancer.
