Abstract excerpt
T5-PRF cells are insensitive to the growth-stimulatory effects of estrogen while still retaining expression of estrogen receptor-alpha (ER-alpha). In the apparent absence of ligand, T5-PRF cells have a 3. 6+/-0.5 (s.e.m.)-fold increased basal ER-alpha activity and elevated basal progesterone receptor levels compared with the parent, estrogen-sensitive, T5 cells. Long-range ER-alpha reverse transcription-PCR was...
