Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...

The effect of amino acid enantiomers on activity of selected enzymes in soil
This work was aimed to test the effect of selected amino acid enantiomers on activity of casein-protease and acid phosphomonoesterase in soil. Casein-protease was selected due to its key role in nitrogen mineralization and acid phosphomonoesterase due to

Regulation of System x\u3csub\u3ec\u3c/sub\u3e\u3csup\u3e-\u3c/sup\u3e by Pharmacological Manipulation of Cellular Thiols [PDF]
The cystine/glutamate exchanger (system xc-) mediates the transport of cystine into the cell in exchange for glutamate. By releasing glutamate, system xc- can potentially cause excitotoxicity.

Slc7a11-Mediated Cystine/Glutamate Antiport Reprograms Macrophage Polarization and Ameliorates Atherosclerosis. [PDF]
Slc7a11‐mediated cystine uptake and glutathione synthesis inhibits M1 macrophage polarization by reducing Stat1 phosphorylation and markers expressions and promotes M2 macrophage polarization by enhancing Stat6 phosphorylation and markers expressions.

Objective Beyond its role as a ribosome‐targeting antibiotic, linezolid was recently shown to modulate immune responses by inhibiting mitochondrial translation. Because mitochondrial dysfunction is implicated in various fibrotic diseases, including systemic sclerosis (SSc), this study aimed to evaluate the antifibrotic potential of linezolid and ...

Sulfur Amino Acids in Diet-induced Fatty Liver: A New Perspective Based on Recent Findings
The relationship of sulfur amino acids to diet-induced fatty liver was established 80 years ago, with cystine promoting the condition and methionine preventing it.
