Abstract:Multidrug resistance (MDR) in cancer manifests due to cross-resistance to chemotherapeutic drugs with neither structural nor functional relationship, markedly by increased expression and activity of ABC superfamily transporters. Evidences indicate sphingolipids as substrates to ABC proteins in processes such as cell signaling, membrane biosynthesis and inflammation, and products of its biosynthetic route were shown to favor cancer progression. Glucosylceramide (GlcCer) is a ubiquitous glycosphingolipid (GSL) g… Show more
