we properly deliver C6 ceramide within low hazardous nanoliposomal supplements to the drug-resistant PANC 1 human pancreatic cancer model. The professional apoptotic sphingolipid metabolite, ceramide, is endogenously produced by chemo or radio solutions, and exogenous short chain ceramide has demonstrated an ability to heat shock protein inhibitor enhance chemotherapy-induced cytotoxicity. Among the exciting aspects of as a chemotherapeutic using ceramide is the selectivity for inducing apoptosis in cancer cells. For example, we previously demonstrated that nanoliposomal C6 ceramide induces cell growth arrest and apoptosis in breast cancer cells and melanomas, but not non transformed mammary gland epithelial cells or melanocytes. Mechanisms underlying these observations aren’t fully understood, but might reveal decreased metabolic process of the supplements in cancer cells and/ or superior promitogenic signaling in transformed cells. Specific promitogenic Akt and signaling cascades such carcinoid tumor as protein kinase C, Erk, are activated or overexpressed in numerous cancers. Mechanistically, ceramide forms structured membrane microdomains, recruiting PKC to pre formed Aktsignalsomes. Ceramide destined PKC inactivates pro success Akt via phosphorylation at 34. In an identical situation, we’ve shown that ceramide inhibits PKC/Erk connections. 17 Regardless of the increased solubility of short-chain ceramide, its therapeutic effectiveness is bound because of its impermeability and to its inclination to precipitate in biological fluids. To improve solubility and to protect from metabolic rate, systemic delivery for ceramide has accepted nano options. Recent reports have established the utility of ceramide delivery in nanoliposomes for your therapy of hepatocellular carcinoma, breast cancer, large granular lymphocytic leukemia and melanoma animal models. The Nano-technology Characterization Laboratory of the National Fingolimod supplier Cancer Institute has recently reported the lack of toxicology, and the pharmacokinetic profile, of ceramide enriched nanoliposomes. Further restrictions of as an anticancer healing ceramide arises from metabolism into pro mitogenic phosphorylated derivatives, that have been implicated in multidrug resistant cellular phenotypes. Recently, we’ve shown that the fate of exogenously shipped C6 ceramide is cell type dependent and concentration dependent. 23 Like, in PANC 1 cells, higher concentrations of C6 ceramide were preferentially metabolized to glucosylceramide, a lipid connected to multidrug resistant phenotypes. Thus, development of glucosylceramide synthase inhibitors can improve the therapeutic efficacy of nanoliposomal ceramide. Multiple labs, including our very own, have reported that the PANC 1 cell line is more chemoresistant than other cell lines, often exhibiting higher IC50 values.
