β-Sitosterol 3-O-D-glucoside increases ceramide levels in the stratum corneum via the up-regulated expression of ceramide synthase-3 and glucosylceramide synthase in a reconstructed human epidermal keratinization model.

open access: yesPLoS ONE, 2021
β-Sitosterol 3-O-d-glucoside (BSG) is known to act as an agonist by binding to estrogen receptors, and estrogen has been reported to enhance the activity of β-glucocerebrosidase, an epidermal ceramide metabolizing enzyme.

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

open access: yes, 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.

Roles of Ceramide Synthase and Ceramide Clearence Genes in Nilotinib-Induced Cell Death in Chronic Myeloidleukemia Cells [PDF]

open access: yes, 2011
In this study, we aimed to increase the sensitivity of human K562 and Meg-01 chronic myeloid leukemia (CML) cells to nilotinib by targeting bioactive sphingolipids, in addition to investigating the roles of ceramide metabolizing genes in nilotinib ...

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

open access: yesJournal 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.

Lactosylceramide contributes to mitochondrial dysfunction in diabetes

open access: yesJournal of Lipid Research, 2016
Sphingolipids have been implicated as key mediators of cell-stress responses and effectors of mitochondrial function. To investigate potential mechanisms underlying mitochondrial dysfunction, an important contributor to diabetic cardiomyopathy, we ...

Ceramide-1-Phosphate Is Involved in Therapy-Induced Senescence

open access: yes, 2022
Sphingolipids are key signaling lipids and their dysregulation has been associated with various cellular processes. We have previously shown significant changes in sphingolipids in therapy-induced senescence, a state of cell cycle arrest as a response to

Ceramide Synthase 6 Is a Novel Target of Methotrexate Mediating Its Antiproliferative Effect in a p53-Dependent Manner. [PDF]

open access: yesPLoS ONE, 2016
We previously reported that ceramide synthase 6 (CerS6) is elevated in response to folate stress in cancer cells, leading to enhanced production of C16-ceramide and apoptosis. Antifolate methotrexate (MTX), a drug commonly used in chemotherapy of several
