摘要
Cholesterol is one of the major lipids of plasma membranes. Recently, we have shown that cholesterol depletion by methyl-beta-cyclodextrin (M beta CD) induces the activation of the Wnt/beta-catenin pathway and enhances myogenic differentiation. Here, we show that M beta CD-conditioned media accelerates myogenesis in a similar way as M beta CD does, suggesting that the effects induced by M beta CD could be caused by soluble factors present in the culture medium. Soluble Wnt-3 protein is significantly enhanced in M beta CD-conditioned medium. Wnt-3a-enriched media induces myogenesis as much as M beta CD does, whereas Wnt-5a-enriched media inhibits. We suggest that Wnt-3a is involved in the myogenic induction observed after cholesterol depletion.
