BF did not induce the expression of ABCD3. Induction of this gene was detected in mice treated with fenofibrate, and considered to be the mechanism by which fibrates might be useful in correcting the metabolic defect in X-ALD (Berger et al 1999; Netik et al 1999). This evidence concerns the gene ABCD3 and X-linked adrenoleukodystrophy.
