1 Dihydrotestosterone differentially modulates the mitogen-activated protein kinase and the phosphoinositide 3-kinase/Akt pathways through the nuclear and novel membrane androgen receptor in C6 cells. Dihydrotestosterone AKT serine/threonine kinase 1 Homo sapiens
2 In this study, using a glial cell model (C6 cells) that we found to express the AR, we identified that DHT increased the phosphorylation of both ERK and Akt, key effectors of the neuroprotection-associated MAPK and phosphoinositide 3-kinase signaling pathways, respectively, and ERK phosphorylation was blocked by the AR antagonist, flutamide. Dihydrotestosterone AKT serine/threonine kinase 1 Homo sapiens
3 In contrast, the membrane-impermeable, BSA-conjugated androgen (DHT-BSA) caused a dose-dependent suppression of ERK and Akt phosphorylation, suggesting the existence of a novel membrane-associated AR that mediates this opposite effect on neuroprotective signaling. Dihydrotestosterone AKT serine/threonine kinase 1 Homo sapiens
