Exposure of rat epididymal adipose tissue to insulin leads to a 2-fold increase in incorporation of [32P]phosphate into ATP citrate lyase and a cytoplasmic protein of Mr 22000. A smaller increase and decrease in incorporation into cytoplasmic proteins of Mr 63000 and 20000 respectively were also observed. Subsequent addition of anti-insulin serum largely reversed these changes within 15 min, indicating that the alterations in 32P incorporation represented changes in net phosphate content of the proteins.

Activation of CD8+ T cells necessitates rapid metabolic reprogramming to fulfill the substantial biosynthetic demands of effector functions. However, the posttranscriptional mechanisms underpinning this process remain obscure. The transfer RNA (tRNA) N1-methyladenine (m1A) modification, essential for tRNA stability and protein translation, has an undefined physiological function in CD8+ T cells, particularly in antitumor responses.

Short-term blockade of the protein S100A9 improves cardiac performance in mice after myocardial infarction (MI). The implications upon ATP production during this process are not known.

Background/objectives: Chronic gut dysbiosis due to a high-fat diet (HFD) instigates cardiac remodeling and heart failure with preserved ejection fraction (HFpEF), in particular, kidney/volume-dependent HFpEF. Studies report that although mitochondrial ATP citrate lyase (ACLY) supports cardiac function, it decreases more in human HFpEF than HFrEF. Interestingly, ACLY synthesizes lipids and creates hyperlipidemia.

Melatonin (Mel) is a tryptophan-derived (N-acetyl-5-methoxytryptamine) molecule. In the present study, role of Mel in the regulation of various anaplerotic enzymes is discussed in relation to N metabolism and H-ATPase activity in mung bean under Cd stress. The application of Mel to the Cd-stressed mung bean seedlings was remarkable in improving the activity of hexokinase (35.

Background/objectives: Hyperlipidemia is a serious risk factor for cardiovascular diseases and liver steatosis. In this work, we explored the effect of an herbal formula (CBF) containing immature pods and extracts on lipid metabolism disorders and lipoprotein-rich plasma (LRP) oxidation in mice.
Methods: The phenolic composition was determined using HPLC-DAD analysis.
