Abstract

Cisplatin, a DNA crosslinking agent, is widely used for the treatment of a variety of solid tumors. Numerous studies have demonstrated that sphingolipid metabolism, which acts as a target for cisplatin treatment, is a highly complex network that consists of sphingolipid signaling molecules and related catalytic enzymes. Ceramide (Cer), which is the central molecule of this network, has been established to induce apoptosis. However, another molecule, sphingosine-1-phosphate (S1P), exerts the opposite function, i.e., serves as a regulator of pro-survival. Other sphingolipid molecules, including dihydroceramide, ceramide-1-phosphate, glucosylceramide (GluCer), and sphingosine (Sph), or sphingolipid catalytic enzymes such as Sph kinase (SphK), Cer synthase (CerS), and S1P lyase, have also attracted considerable attention, particularly Cer, GluCer, SphK, CerS, and S1P lyase, which have been implicated in cisplatin resistance. This review summarizes specific molecules involved in sphingolipid metabolism and related catalytic enzymes affecting the anticancer effect of cisplatin, particularly in relation to induction of apoptosis and drug resistance.

Keywords: Apoptosis, Sphingolipid metabolism, Drug resistance, Cisplatin, Anticancer

Core tip: Cisplatin classifies as a classical anticancer drug and DNA is identified as the most important target of cisplatin. However, increasing evidences have testified that sphingolipid metabolism is associated with the anticancer effect of cisplatin. In this mini-review, we discussed sphingolipid signaling molecules and/or related enzymes affected the anticancer effect of cisplatin, particularly in cisplatin-induced cancer cell apoptosis and drug resistance. Targeting these sphingolipid molecules and enzymes might contribute to the development of novel anticancer strategies or to increase the sensitivity of currently used drugs.
