Quantitative analysis of the expression of ACAT 1 genes in human tissues by real-time PCR2

Journal of Lipid Research, 2004
ACAT (also called sterol o-acyltransferase) catalyzes the esterification of cholesterol by reaction with long-chain acyl-CoA derivatives and plays a pivotal role in the regulation of cholesterol homeostasis.

The birth and life of lipid droplets: learning from the hepatitis C virus.: Lipid droplets in HCV infection [PDF]

, 2011
International audienceLDs (lipid droplets) are probably the least well-characterized cellular organelles. Having long been considered simple lipid storage depots, they are now considered to be dynamic organelles involved in many biological processes ...

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.

Sphingolipid desaturase DEGS1 is essential for mitochondria-associated membrane integrity

The Journal of Clinical Investigation, 2023
Sphingolipids function as membrane constituents and signaling molecules, with crucial roles in human diseases, from neurodevelopmental disorders to cancer, best exemplified in the inborn errors of sphingolipid metabolism in lysosomes. The dihydroceramide

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Cholesterol feeding strongly reduces hepatic VLDL-triglyceride production in mice lacking the liver X receptor alpha [PDF]

, 2007
The oxysterol-activated nuclear receptor liver X receptor alpha (LXR alpha) has been implicated in the control of both cholesterol and fatty acid metabolism.

Reprogramming SREBP1‐dependent lipogenesis and inflammation in high‐risk breast with licochalcone A: A novel path to cancer prevention

International Journal of Cancer, Volume 158, Issue 7, Page 1927-1940, 1 April 2026.
What's new? Endocrine drugs repurposed from treatment protocols are the primary medications available for breast cancer (BC) prevention in at‐risk women. Adverse effects, however, significantly minimize uptake and prevention impact. Here, the authors investigated licochalcone A (LicA), a non‐endocrine anti‐inflammatory agent with reported hematologic ...

Impaired Adipose Anabolism in Pancreatic Cancer Cachexia Is Reversed by HuR Inhibition

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.
ABSTRACT Background Cachexia is defined by chronic loss of fat and muscle, is a frequent complication of pancreatic ductal adenocarcinoma (PDAC) and negatively impacts patient outcomes. Nutritional supplementation cannot fully reverse tissue wasting, and the mechanisms underlying this phenotype are unclear.
