Mitochondrial ceramide-rich macrodomains functionalize Bax upon irradiation. [PDF]

PLoS ONE, 2011
BACKGROUND:Evidence indicates that Bax functions as a "lipidic" pore to regulate mitochondrial outer membrane permeabilization (MOMP), the apoptosis commitment step, through unknown membrane elements.

Lycoperoside H, a Tomato Seed Saponin, Improves Epidermal Dehydration by Increasing Ceramide in the Stratum Corneum and Steroidal Anti-Inflammatory Effect

Molecules, 2021
Tomatoes are widely consumed, however, studies on tomato seeds are limited. In this study, we isolated 11 compounds including saponins and flavonol glycosides from tomato seeds and evaluated their effects on epidermal hydration.

AMPK inhibitor Compound C stimulates ceramide production and promotes Bax redistribution and apoptosis in MCF7 breast carcinoma cells

Journal of Lipid Research, 2009
Compound C is commonly used as an inhibitor of AMP-activated protein kinase (AMPK), which serves as a key energy sensor in cells. In this study, we found that Compound C treatment of MCF7 cells led to Bax redistribution from the cytoplasm to mitochondria

Ceramide mediates radiation-induced germ cell apoptosis via regulating mitochondria function and MAPK factors in Caenorhabditis elegans

Ecotoxicology and Environmental Safety, 2021
Studies about radiation damage in vivo are very significant for healthy risk assessment as well as cancer radiotherapy. Ceramide as a second messenger has been found to be related to radiation-induced apoptosis. However, the detailed mechanisms in living

All members in the sphingomyelin synthase gene family have ceramide phosphoethanolamine synthase activity[S]

Journal of Lipid Research, 2015
Sphingomyelin synthase-related protein (SMSr) synthesizes the sphingomyelin analog ceramide phosphoethanolamine (CPE) in cells. Previous cell studies indicated that SMSr is involved in ceramide homeostasis and is crucial for cell function.

Genetic Determinants of Circulating Sphingolipid Concentrations in European Populations [PDF]

, 2009
Sphingolipids have essential roles as structural components of cell membranes and in cell signalling, and disruption of their metabolism causes several diseases, with diverse neurological, psychiatric, and metabolic consequences.

Synthesis of Cyclopropene‐Modified Fatty Acids Allows Single‐Cell Quantification of Uptake by Immune Cells

Angewandte Chemie, EarlyView.
Cyclopropene fatty acids have been made that allow the study of fatty acid uptake in complex mixtures of immune cells with single cell resolution and combined with metabolic and proteomic analysis so that for the first time nutrient uptake can be correlated to the phenotype of single immune cell.

Sphingomyelin synthase-related protein generates diacylglycerol via the hydrolysis of glycerophospholipids in the absence of ceramide

Journal of Biological Chemistry, 2021
Diacylglycerol (DG) is a well-established lipid second messenger. Sphingomyelin synthase (SMS)-related protein (SMSr) produces DG and ceramide phosphoethanolamine (CPE) by the transfer of phosphoethanolamine from phosphatidylethanolamine (PE) to ceramide.
