Mechanisms involved in cellular ceramide homeostasis

Nutrition & Metabolism, 2012
Sphingolipids are ubiquitous and critical components of biological membranes. Their biosynthesis starts with soluble precursors in the endoplasmic reticulum and culminates in the Golgi complex and plasma membrane. Ceramides are important intermediates in

Association Between the Root Canal Microbiome and Apical Lesion Size: An Observational Shotgun Metagenomic Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim The aim was to characterize the taxonomic and functional composition of the microbiome involved in primary endodontic infections and to evaluate their association with the periapical lesion size using shotgun metagenomic sequencing. Methodology Samples from primary root canal infections diagnosed with apical periodontitis were analysed ...

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.

Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola

Insect Molecular Biology, EarlyView.
Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

High cholesterol absorption efficiency enhances proatherogenic properties of low-density lipoprotein particles. [PDF]

J Intern Med
Abstract Background and Aims High cholesterol absorption efficiency is determined by genetic variation in small intestinal sterol transporters and affects one‐third of individuals. Their risk for atherosclerotic cardiovascular disease (ASCVD) is increased compared with low cholesterol absorbers, despite similar serum lipid concentrations.

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.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

A Quarter Century of EHD Protein Research: From Endosomal Recycling to Ciliopathies

Traffic, Volume 27, Issue 3, September 2026.
Human EHD protein subcellular localization. ABSTRACT Eps15 homology domain‐containing proteins comprise a conserved family of membrane‐remodeling ATPases that regulate endocytic trafficking, membrane fission, receptor recycling, primary ciliogenesis and membrane dynamics across eukaryotes. Since the initial identification of EHD1 and its Caenorhabditis

Immune, molecular and genetic profiles of gastric signet ring cell carcinoma: Recent progress and future challenges

International Journal of Cancer, Volume 159, Issue 1, Page 11-29, 1 July 2026.
Abstract Gastric signet ring cell carcinoma (GSRCC) is a special type of gastric cancer common in young women. Diffuse gastric cancer (DGC) begins with intramucosal lesions comprising differentiated GSRCC cells. Genetically, GSRCC and DGC are clonally identical, with their morphology influenced by extracellular Wnt signaling.

A Step‐by‐Step Protocol From METASPACE to Biological Interpretation

Journal of Mass Spectrometry, Volume 61, Issue 7, July 2026.
ABSTRACT Mass spectrometry imaging (MSI) represents an exceptional tool for exploring complex biological systems spatially at the molecular level. However, its multidimensional nature and large data outputs make it challenging to extract meaningful biological insights. Advancements such as the METASPACE platform allow researchers to efficiently process,
