Susceptibility to UPEC UTI in both male and female hosts was potentiated with 5α-dihydrotestosterone, while males with androgen receptor deficiency and androgenized females treated with the androgen receptor antagonist enzalutamide were protected from severe pyelonephritis.
However, in 1 in 10 control NGSF lines androgen receptor activity was at the lower limit of assay sensitivity (1 to 2 fmol/mg protein) demonstrating that NGSF may not be reliable for family studies of androgen receptor deficiency.
Finally, addition of IGF inhibitors successfully masked the AR deficiency-induced Akt activation, and inhibitions of Akt, IGF1, and IGF2 pathways reversed the AR depletion effects on the adipogenesis process.
