The effect of 3-methylcholanthrene on postlanosterol cholesterol biosynthetic pathways in mouse skin.


Repeated topical application of 3-methylcholanthrene to the backs of BALB/c mice lowered the tissue levels of lathosterol and provitamin D3, intermediates in one of the cholesterol biosynthetic pathways (the delta 7 pathway), though the activities of lathosterol 5-desaturase and provitamin D3 7-reductase were similar to those of control animals. These… (More)
