Artificial Receptor in Synthetic Cells Performs Transmembrane Activation of Proteolysis

Advanced Biology, EarlyView.
Transmembrane signaling is the hallmark of living cells and is among the highest challenges for the design of synthetic cells. Herein, an artificial receptor based on the chemistry of self‐immolative linkers is used to communicate information across the lipid bilayer, for transmembrane activation of enzymatic activity. Abstract The design of artificial,

Fatty acid flux suppresses fatty acid synthesis in hamster intestine independently of SREBP-1 expression

Journal of Lipid Research, 2003
Hamsters were fed a control diet or diets containing palm, olive, safflower, or fish oil for 2 weeks. In villus cell populations from duodenum, jejunum, and ileum, rates of intestinal fatty acid and cholesterol synthesis were estimated, as were sterol ...

Control of Fatty Acid Synthesis in Bacteria [PDF]

Journal of Bacteriology, 1972
When glycerol-requiring auxotrophs of Bacillus subtilis are deprived of glycerol, the synthesis of fatty acids continues at an apparent rate of 20 to 50% that of supplemented cultures. The newly synthesized fatty acids are not incorporated into phospholipid and accumulate as free fatty acids. These molecules undergo

Murine Models and Human Cell Line Models to Study Altered Dynamics of Ovarian Follicles in Polycystic Ovary Syndrome

Advanced Biology, EarlyView.
The manuscript examines preclinical murine and human models to study polycystic ovary syndrome (PCOS), delving into the cellular and molecular mechanisms underlying altered ovarian follicular dynamics. It explores the cellular interactions involved in normal and PCOS ovaries and outlines the current and novel strategies in the search for preclinical ...

Observation of Cholesterol Dissolved in Microscopic Deposits of Free Fatty Acids in the Lumen of an Aorta of a Mouse Model for Human Atherosclerosis [PDF]

SPIE 7 5321A-11 (2004), 2008
The Raman spectrum of microscopic droplets of lipid material on the lumen of the aorta of an apolipoprotein E knock-out mouse were reported in the proceedings of an SPIE conference. Based on the absence of the carbonyl band in the spectrum, at that time it was determined that the spectrum represents free fatty acids rather than triglycerides.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Post-heparin phospholipase and fatty acid transesterification in human plasma

Journal of Lipid Research, 1965
The incubation of post-heparin plasma and egg phosphatidyl ethanolamine in the presence of methanol, ethanol, or glycerol resulted in the synthesis of fatty acid esters of these alcohols.
