Figure 4. Effects of nicotine (N), and glutathione (G) on the metabolism of 14C-4-androstenedione in HGF.

Figure 4

The yields of Diol, DHT and androstanedione (A) are shown for the control (C) and in response to testing agents. Means from 6 human gingival fibroblast (HGF) cell-line incubations are shown, for the substrate 14C-4-androstenedione. N = 250 μg/ml; G1–4: 1–4 μg/ml.
