Glucolipotoxicity impairs ceramide flow from the endoplasmic reticulum to the Golgi apparatus in INS-1 β-cells. [PDF]
PLoS ONE, 2014 Accumulating evidence suggests that glucolipotoxicity, arising from the combined actions of elevated glucose and free fatty acid levels, acts as a key pathogenic component in type II diabetes, contributing to β-cell dysfunction and death.

Advanced Science, EarlyView.ABSTRACT High‐fat diet (HFD)‐induced hepatic injury represents a pathology observed across vertebrates, yet the underlying mechanisms remain incompletely understood. Herein, the present study identifies phosphatidylethanolamine methyltransferase (Pemt), a key enzyme in phosphatidylcholine synthesis, as a critical regulator of mitochondrial homeostasis ...

Ceramide Mediates Acute Oxygen Sensing in Vascular Tissues [PDF]
, 2014 Aims: A variety of vessels, such as resistance pulmonary arteries (PA) and fetoplacental arteries and the ductus arteriosus (DA) are specialized in sensing and responding to changes in oxygen tension. Despite opposite stimuli, normoxic DA contraction and

Journal of Lipid Research, 1972 Methylation analysis of ceramide tetrasaccharide isolated from human erythrocytes gave acetates of 2,3,6-tri-O-methylgalactitol and 2,4,6-tri-O-methylgalactitol in a ratio of 1 : 1, and about 50% of the galactose was oxidized by periodate.

Adipocyte Myoglobin Is a Determinant of Energy Expenditure and a Potential Target to Limit Obesity
Advanced Science, EarlyView.Myoglobin, known as a muscle oxygen‐carrying protein, is shown to play a key role in fat cells that burn energy. Loss of myoglobin reduces the body's ability to generate heat and increases obesity risk, while restoring it improves metabolism. The study identifies myoglobin as a regulator of fat burning and a potential target to enhance energy ...

C6-ceramide Inhibits the Motility of Anaplastic Thyroid Carcinoma Cells [PDF]
Background: Anaplastic thyroid carcinoma (ATC) is an aggressive type of thyroid cancer, and its metastasis requires cell motility. Ceramide is involved in a variety of biological processes, including inflammation, cell signaling, cell motility, and ...

Advanced Science, EarlyView.RLIM‐mediated SLC7A11 polyubiquitination is required for SPTBN2‐mediated trafficking and membrane localization of SLC7A11, which enables oligodendrocyte precursor cells to be resistant to ferroptosis and safeguards oligodendrocyte lineage progression and thus myelination.

Chemical structure of ceramide species. [PDF]
, 2018 In this study, we evaluated the effect of SSE and its major component, tiliroside, on ceramide content in the SC and the expression of ceramide synthesis-related enzymes in a new reconstructed human epidermal keratinization model (3DHEEs), which we ...

Ceramide signaling in apoptosis [PDF]
British Medical Bulletin, 1997 The sphingomyelin pathway is a ubiquitous, evolutionarily conserved signaling system initiated by hydrolysis of the plasma membrane phospholipid sphingomyelin to generate ceramide. Ceramide acts as a second messenger in activating the apoptotic cascade. Diverse cytokine receptors and environmental stresses utilize ceramide to signal apoptosis.

Advanced Science, EarlyView.Intermittent fasting reshapes the gut microbiota in diabetic cardiomyopathy, restoring Akkermansia muciniphila and the microbiota‐associated metabolite 1‐methyl‐L‐histidine. This shift is linked to improved cardiac lipid homeostasis, reduced lipid peroxidation, and attenuated myocardial injury, highlighting a gut microbiota–metabolite–lipid axis in ...
