Testosterone 8-20 androgen receptor Homo sapiens 123-125 15472231-3 2004 AR expression was evaluated by immunohistochemical staining, confocal immunofluorescence, and immunoelectron microscopy in sections of vastus lateralis from healthy men before and after treatment with a supraphysiological dose of testosterone enanthate. Testosterone 230-242 androgen receptor Homo sapiens 0-2 15472231-9 2004 Immunoelectron microscopy revealed aggregation of immunogold particles in nucleoli of satellite cells and myonuclei; testosterone treatment increased nucleolar AR density. Testosterone 117-129 androgen receptor Homo sapiens 160-162 15472231-12 2004 Incubation of satellite cell cultures with supraphysiological testosterone and dihydrotestosterone concentrations (100 nm testosterone and 30 nm dihydrotestosterone) modestly increased AR protein levels. Testosterone 62-74 androgen receptor Homo sapiens 185-187 15472231-12 2004 Incubation of satellite cell cultures with supraphysiological testosterone and dihydrotestosterone concentrations (100 nm testosterone and 30 nm dihydrotestosterone) modestly increased AR protein levels. Testosterone 86-98 androgen receptor Homo sapiens 185-187
