Among these mechanisms, small non-coding RNAs (sRNAs) play essential roles in regulating post-transcriptional pathways that may aid in stress adaptation in mycobacteria.

Transcriptomic analyses revealed that overexpression of ncBCG427 substantially altered gene expression profiles in these three stress environments, with differentially expressed genes (DEGs) in the same pathways enriched for different stressors. Notably, we identified 22 DEGs that responded to two or three stress conditions, implicating their involvement in pathways related to the sulfur relay system, ribosome function, folate biosynthesis, and the biosynthesis of cofactors.

Research suggests that the initiation and progression of CVDs are associated with antibiotic-induced gut dysbiosis. Antibiotics are primarily intended to be used to treat bacterial infections, which can alter gut microbiota (GM) composition, by lowering the abundance of beneficial bacteria, like Firmicutes, Bacteroidetes, and increasing the profusion of Enterobacteriaceae, leading to harm on gut health. Additionally, it reduces short-chain fatty acids (SCFAs) and bile acid metabolism, increases trimethylamine N-oxide (TMAO) production, intestinal permeability allowing lipopolysaccharide (LPS) and TMAO into systemic circulation. SCFAs play a key role in lipid metabolism, inflammation, and strengthening of the intestinal barrier, and participate in CVDs through FFAR2 and FFAR3 receptors, whereas dysbiosis reduces SCFAs levels and worsens these effects. TMAO enhances oxidative stress, inflammation, endothelial dysfunction, and cholesterol dysregulation, thus worsening CVDs. Furthermore, LPS develops systemic inflammation, insulin resistance, and endothelial dysfunction by activating the NF-κB pathway.
