Article Title: Chemotherapeutic agents-induced ceramide-rich platforms (CRPs) in endothelial cells and their modulation
Abstract: The prevailing mechanism of action of chemotherapeutic drugs has been challenged by the role of ceramide, a second messenger, shown to induce apoptosis, differentiation, growth arrest, senescence, and autophagy in different cells (Chabner BA, Roberts TG Jr, Nat Rev Cancer 5:65–72, 2005; Jacobi J et al, Cell Signal 29:52–61, 2017; Rotolo J et al, J Clin Invest 122:1786–1790, 2012; Truman JP et al, PLoS One 5:e12310, 2010). Certain chemotherapeutic drugs activate the acid sphingomyelinase (ASMase)/ceramide pathway, generating ceramide in the tumor endothelium and this microvascular dysfunction is crucial for the tumor response. Ceramide has fusigenic properties and as such, when generated within the plasma membrane, initiates the oligomerization of ceramide-and cholesterol-rich domains in the outer leaflet of the plasma membrane, leading to the formation of ceramide-rich microdomains/platforms (CRP) (Jacobi J et al, Cell Signal 29:52–61, 2017; Truman JP et al, PLoS One 5:e12310, 2010; van Hell AJ et al, Cell Signal 34:86–91, 2017; Hajj C, Haimovitz-Friedman A, Handb Exp Pharmacol 216:115–130, 2013) known as “signaling platform.” This chapter will discuss the generation, detection, and quantitation of CRP and their possible modulation in endothelial cells, in vitro and in vivo in response to certain chemotherapeutic drugs. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.
