Cumulative DHEAS production after incubation of HepG2 cells with DHEA only (10−5 mol/L), coincubation of DHEA (10−5 mol/L) with T (10−6 mol/L), DHEA (10−5 mol/L) with DHT (10−6 mol/L), and DHEA (10−5 mol/L) with E2 (10−6 mol/L). As compared with DHEA only at 24 hours, ∗P=.01 and ∗∗P=.08.

Cumulative DHEAS production after incubation of HepG2 cells with DHEA only (10−5 mol/L), coincubation of DHEA (10−5 mol/L) with insulin 100 ng/mL, and DHEA (10−5 mol/L) with insulin 10 ng/mL. INS = insulin.
