A gonadotropin-releasing hormone-II antagonist induces autophagy of prostate cancer cells.
Gonadotropin-releasing hormone-I (GnRH-I) is known to directly regulate prostate cancer cell proliferation. However, the role of GnRH-II in prostate cancer is unclear. Here, we investigated the effect of the GnRH-II antagonist trptorelix-1 (Trp-1) on growth of PC3 prostate cancer cells. Trp-1 induced growth inhibition of PC3 cells in vitro and inhibited growth of PC3 cells xenografted into nude...
متن کاملApoptotic Death of Prostate Cancer Cells by a Gonadotropin-Releasing Hormone-II Antagonist
Gonadotropin-releasing hormone-I (GnRH-I) has attracted strong attention as a hormonal therapeutic tool, particularly for androgen-dependent prostate cancer patients. However, the androgen-independency of the cancer in advanced stages has spurred researchers to look for new medical treatments. In previous reports, we developed the GnRH-II antagonist Trp-1 to inhibit proliferation and stimulate ...
متن کاملLuteinizing hormone-releasing hormone induces nuclear factor kappaB-activation and inhibits apoptosis in ovarian cancer cells.
More than 80% of human ovarian cancers express LHRH and its receptor as part of a negative autocrine mechanism of growth control. This study was conducted to investigate whether LHRH affects apoptosis in ovarian cancer. EFO-21 and EFO-27 ovarian cancer cells were treated with LHRH agonist Triptorelin or with cytotoxic agent Doxorubicin in the absence or presence of Triptorelin. Apoptotic cells ...
متن کاملGonadotropin-releasing hormone induces apoptosis of prostate cancer cells: role of c-Jun NH2-terminal kinase, protein kinase B, and extracellular signal-regulated kinase pathways.
A standard therapy used today for prostate cancer is androgen ablation by gonadotropin-releasing hormone analogs (GnRH-a). Although most patients respond to androgen ablation as an initial systemic therapy, nearly all cases will develop androgen resistance, the management of which is still a major challenge. Here, we report that GnRH-a can directly induce apoptosis of the androgen-independent p...
متن کاملGonadotropin-releasing hormone agonist use in men without a cancer registry diagnosis of prostate cancer
BACKGROUND Use of gonadotropin-releasing hormone (GnRH) agonists has become popular for virtually all stages of prostate cancer. We hypothesized that some men receive these agents after only a limited work-up for their cancer. Such cases may be missed by tumor registries, leading to underestimates of the total extent of GnRH agonist use. METHODS We used linked Surveillance, Epidemiology and E...
