2025年5月19日 · While this study provides valuable insights into the role of gut microbiota in NAC permeability using rat models, it is important to recognize the compositional differences between rat …

2024年1月5日 · Gut microbiome composition and expression of stem cell markers did not change on the low cystine diet. Remarkably, stem cell markers, as well as the proliferation marker Ki67, were …

2022年3月8日 · These results suggested that the protective effect of cystine is gut microbiota dependent, that is, gut microbial metabolites from cystine, such as RSS, might play a protective role …

2024年10月28日 · We demonstrate a dual-pathway mechanism for methionine biosynthesis: one directly utilizing cysteine (trans-sulfurylation pathway) and another utilizing H 2 S derived from cysteine …

“With our high-cysteine diet, the gut is the first place that sees a high amount of cysteine,” Chi says. Cysteine has been previously shown to have antioxidant effects, which are also beneficial, but this …

2024年10月31日 · Sulfur, a critical element for bacterial growth, is not directly utilized by bifidobacteria, rendering the sulfur-containing amino acid biosynthesis pathway, particularly for cysteine and …

2022年8月5日 · Cystine is the dipeptide of cysteine, and it seems that most parts of cysteine may be transported across the cell membrane as cystine, mainly mediated by xCT, a glutamate/cystine …

2021年3月24日 · 218 revealed that putative cysteine-degrading bacteria are ubiquitous inhabitants of the human gut 219 microbiome and have significant higher relative abundance than sulfate-reducing …

There are two major sources for H 2 S production in the human gut microbiota, dissimilatory sulfate reduction (DSR) and the degradation of the sulfur-containing amino acids cysteine and methionine …

2024年12月20日 · Hydrogen sulfide (H 2 S) is produced in the gut from cysteine by epithelial cells and by the intestinal microbiota. Initially considered as a toxic gas, the pleiotropic effects of H 2 S are …
