Loss of STARD7 Triggers Metabolic Reprogramming and Cell Cycle Arrest in Breast Cancer

Advanced Science, EarlyView.
Breast cancer cells undergo metabolic and transcriptomic reprogramming to support aberrant cell proliferation. Their mitochondria rely on the transfer of phosphatidylcholine from the endoplasmic reticulum to their membranes by STARD7, a candidate upregulated in breast cancer, to be functional.

Contribution of the precursors and interplay of the pathways in the phospholipid metabolism of the malaria parasite

Journal of Lipid Research, 2018
The malaria parasite, Plasmodium falciparum, develops and multiplies in the human erythrocyte. It needs to synthesize considerable amounts of phospholipids (PLs), principally phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylserine

Multi‐Omics and ‐Organ Insights into Energy Metabolic Adaptations in Early Sepsis Onset

Advanced Science, EarlyView.
This study shows that patients at risk of sepsis have a distinct metabolite and lipid signature, including serine and aminoadipic acid, in their serum before clinical diagnosis. A mouse model of sepsis with a compatible serum signature reveals underlying metabolic changes, including mitochondrial adaptation, altered serine‐dependent purine metabolism ...

Localization of the PE methylation pathway and SR-BI to the canalicular membrane

Journal of Lipid Research, 2003
To better understand the regulation of biliary phospholipid and cholesterol excretion, canalicular membranes were isolated from the livers of C57BL/6J mice and abundant proteins separated by SDS-PAGE and identified by matrix-assisted laser desorption ...

KRAS/ABHD17C/ALOX15B Axis Promotes Pancreatic Cancer Progression via Ferroptosis Evasion

Advanced Science, EarlyView.
Phosphorylation of ABHD17C induced by KRASmut/ERK signaling facilitates ALOX15B depalmitoylation and degradation via the CUL4/DDB1/DCAF10 complex, thereby enabling KRASmut‐PDAC cell to evade ferroptosis. Methyl protodioscin inhibits KRASmut‐PDAC progression by disrupting the ABHD17C/ALOX15B interaction and inducing ferroptosis, which represents a ...

Gut Parabacteroides distasonis‐derived Indole‐3‐Acetic Acid Promotes Phospholipid Remodeling and Enhances Ferroptosis Sensitivity via the AhR‐FASN Axis in Bladder Cancer

Advanced Science, EarlyView.
Indole‐3‐acetic acid (3‐IAA) derived from gut P. distasonis binds to AhR in bladder cancer cells and downregulates FASN transcription, thereby increasing sensitivity to ferroptosis and suppressing the development of bladder tumors. Specifically, 3‐IAA treatment leads to an increase in the proportion of PC/PE‐PUFAs and a decrease in the proportions of ...

Serum phospholipids during aging: A comprehensive systematic review of cross-sectional and case-control studies [PDF]

Health Promotion Perspectives
Background: The lipidome, as a subset of metabolomics, can undergo significant variations due to several factors, including the aging process. Therefore, this study aims to summarize the relationship between aging and alterations in plasma phospholipids.

Covalent Organic Frameworks‐Delivered Reuterin Drives Trained Immunity in Tumor‐Associated Macrophages to Enhance Melanoma Immunotherapy via Glycerophospholipid Metabolism

Advanced Science, EarlyView.
Covalent organic framework (COF)‐reuterin induces trained immunity in tumor‐associated macrophages, promoting the generation of nitric oxide and reactive oxygen species, thereby enhancing the antitumor immune response. Additionally, COF‐Reuterin directly kills tumor cells while simultaneously eradicating pathogenic intratumoural bacteria.
