Sphingomyelin and ceramide-phosphoethanolamine synthesis by microsomes and plasma membranes from rat liver and brain.

Journal of Lipid Research, 1987
Pulse-chase experiments showed that phosphatidylethanolamine (PE) was the direct precursor for ceramide-phosphoethanolamine, a sphingomyelin analogue, in the same way as phosphatidylcholine was for sphingomyelin.

Opposing roles of DGAT‐mediated lipid droplet biogenesis in the regulation of ferroptosis sensitivity

The FEBS Journal, EarlyView.
Ferroptosis is driven by unrestricted peroxidation of polyunsaturated fatty acyl (PUFA) chains in membrane phospholipids. In triple‐negative breast cancer cells, lipid droplets (LDs) sequester dietary PUFAs, limiting their incorporation into membrane phospholipids, preventing mitochondrial damage, and reducing lipid peroxidation and ferroptosis.

TaRIP2 Positively Regulates Wheat Pollen Wall Formation Through MYB80‐Controlled Lipid Metabolism

Plant Biotechnology Journal, EarlyView.
ABSTRACT Male‐sterile genes and mutants are critical for hybrid seed production in monocotyledonous crops. Lipids are essential structural components of male reproductive organs, such as the anther and pollen. Here, we show that the pollen‐preferential gene TaRIP2 is essential for wheat anther development and pollen formation. RT‐qPCR analysis revealed

Developing giant plasma membrane vesicles from Leishmania cells to investigate the role of membrane proteins in photodynamic inactivation

Photochemistry and Photobiology, EarlyView.
In this study, we developed giant plasma membrane vesicles (GPMVs) from Leishmania amazonensis promastigote membranes to investigate the role of protein‐embedded membranes in methylene blue (MB) photooxidation. Upon MB photoactivation in model lipid membranes (giant unilamellar vesicles, GUVs), a distinct photooxidation effect was observed, marked by ...

Immunomodulatory effects of photodynamic therapy for skin cancer: Potential strategies to improve treatment efficacy and tolerability

Photochemistry and Photobiology, EarlyView.
Photodynamic therapy (PDT) is a nonscarring treatment modality that is widely used for skin cancers and early squamous precursor lesions. PDT was previously thought to work primarily by killing cancer cells directly (via apoptosis or necrosis). However, more recent work indicates that a significant mechanism for PDT is the stimulation of anti‐cancer ...

Longitudinal metabolomics study of phosphate‐adenine‐guanosine‐glucose‐saline‐mannitol stored red blood cells

Transfusion, EarlyView.
Abstract Background The storage of red blood cells (RBCs) is essential for transfusion but leads to storage lesions that compromise RBC quality and increase the risk of transfusion‐related adverse effects, including allergic transfusion reactions (ATRs). Understanding storage‐induced metabolic change is crucial for enhancing transfusion safety.

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

Experimental Physiology, EarlyView.
Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Effects of a Combined Dietary and Physical Activity Intervention on Bone Density, Lean Mass and Fat Mass in Adults: The GOTO Trial

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.
ABSTRACT Background Nutritional weight‐loss interventions are known to reduce bone mineral density (BMD), which can be prevented by adding (resistance) exercise training. However, this combined effect is not well studied in non‐obese adults. In addition, the association between biomarkers and metabolite‐based composite health markers with changes in ...

Circulating Lipoprotein Sphingolipids in Chronic Kidney Disease with and without Diabetes

Biomedicines
Abnormalities of sphingolipid metabolism play an important role in diabetes. We compared sphingolipid levels in plasma and in isolated lipoproteins between healthy control subjects and two groups of patients, one with chronic kidney disease without ...

ORMDL Proteins Turnover via Proteasome and Autophagy Is Cell‐Type Dependent and Tied to Ceramide Homeostasis

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
ORMDL proteins in the endoplasmic reticulum (ER) negatively regulate serine palmitoyltransferase (SPT) activity in response to the rate of de novo sphingolipid synthesis. Disruption of ceramide homeostasis by myriocin or fumonisin B1 (FB1) appears to destabilize the ORMDL‐SPT complex, leading to ORMDL degradation as a feedback mechanism.
