Representative picture of a Northern blot analysis showing the effects of different concentrations of dihydrotestosterone on TNFα-induced VCAM-1 and GAPDH mRNA expression (A) and quantitation by PhosphorImager (B). Quantitation is expressed as means ± SEM of arbitrary densitometric units obtained from three separate experiments. GAPDH was used as an internal control. No significant difference (P < 0.05) from TNFα-only treated cells was found.
