Cholesterol 107-118 progesterone receptor Rattus norvegicus 40-61 17342739-2 2007 The mechanisms involved are unclear but progesterone receptor (PGR) antagonists have been shown to inhibit cholesterol synthesis and induce apoptosis. Cholesterol 107-118 progesterone receptor Rattus norvegicus 63-66 17342739-5 2007 It has been suggested that PGR antagonists in a similar manner induce apoptosis by decreasing cholesterol synthesis and thereby protein isoprenylation. Cholesterol 94-105 progesterone receptor Rattus norvegicus 27-30 17342739-6 2007 In this study we hypothesized that the mechanism by which the nuclear PGR antagonist Org 31,710 induces apoptosis in rat periovulatory granulosa cells, is by decreasing cholesterol synthesis and thereby general cell protein isoprenylation. Cholesterol 169-180 progesterone receptor Rattus norvegicus 70-73 17342739-12 2007 In conclusion, we demonstrate that the PGR antagonist inhibits cholesterol synthesis in granulosa cells but reduced protein isoprenylation is not the mediating mechanism of increased apoptosis as previously hypothesized. Cholesterol 63-74 progesterone receptor Rattus norvegicus 39-42 15385411-0 2005 Progesterone-receptor antagonists and statins decrease de novo cholesterol synthesis and increase apoptosis in rat and human periovulatory granulosa cells in vitro. Cholesterol 63-74 progesterone receptor Rattus norvegicus 0-21 15385411-8 2005 These results show that PR antagonists reduce cholesterol synthesis in periovulatory granulosa cells and that cholesterol synthesis is important for granulosa cell survival.
