X-Adrenoleukodystrophy (X-ALD) is a peroxisomal disorder associated with the abnormal accumulation of very long chain fatty acids (VLCFA) in plasma and tissues. We have demonstrated that the androgen dihydrotestosterone (DHT) and 5 alpha-androstan-3 alpha,17 beta-diol (3 alpha-diol) have favorable effect on VLCFA metabolism. We have investigated the effect of androgens on peroxisomal beta-oxidation, the incorporation of labelled lignoceric acid into cholesterol esters and VLCFA elongation, in cultured skin-fibroblasts from control and X-ALD patients. The androgens significantly increased peroxisomal beta-oxidation in X-ALD fibroblasts although VLCFA levels were not normalized. The major effect was on the incorporation of labelled lignoceric acid into cholesterol esters, since the enhanced lignoceric acid incorporation into cholesterol ester fraction, which occurred in X-ALD fibroblasts, was reduced towards normal values. In contrast, the androgens had no effect on the elongation pathway.
