Myricanol improves metabolic profiles in dexamethasone induced lipid and protein metabolism disorders in mice
This study for the first time applied widely targeted metabolomics to investigate the beneficial effects of MY on glucose, lipids, and protein metabolism in DEX-induced metabolic abnormality in mice. The results showed that MY significantly reversed DEX-induced soleus and gastrocnemius muscle weight loss, muscle fiber damage, and muscle strength loss. MY alleviated DEX-induced metabolic disorders by increasing SIRT1 and glucose transporter type 4 (GLUT4) expressions. Additionally, myricanol prevented muscle cell apoptosis and atrophy by inhibiting caspase 3 cleavages and muscle ring-finger protein-1 (MuRF1) expression. Met...

pH-dependent regulation of an acidophilic < em > O < /em > -acetylhomoserine sulfhydrylase from < em > Lactobacillus plantarum < /em >
Appl Environ Microbiol. 2024 Apr 3:e0011824. doi: 10.1128/aem.00118-24. Online ahead of print.ABSTRACTBacteria have two routes for the l-methionine biosynthesis. In one route called the direct sulfuration pathway, acetylated l-homoserine is directly converted into l-homocysteine. The reaction using H2S as the second substrate is catalyzed by a pyridoxal 5'-phosphate-dependent enzyme, O-acetylhomoserine sulfhydrylase (OAHS). In the present study, we determined the enzymatic functions and the structures of OAHS from Lactobacillus plantarum (LpOAHS). The LpOAHS enzyme exhibited the highest catalytic activity under the weak ac...

Biochemical and structural impact of two novel missense mutations in cystathionine beta-synthase gene associated with homocystinuria
In this study, we present the clinical and biochemical characterization of two novel CBS missense mutations that do not respond to pyridoxine treatment, namely c.689T>A (L230Q) and 215A>T (K72I), identified in a Chinese patient. We observed that the disease-associated K72I genetic variant had no apparent effects on the spectroscopic and catalytic properties of the full-length enzyme. In contrast, the L230Q variant expressed in E. coli did not fully retain heme and when compared to the wild-type enzyme, it exhibited more significant impairments in both the canonical cystathionine-synthesis and the alternative H2S-prod...

Multivitamins co-intake can reduce the prevalence of kidney stones: a large-scale cross-sectional study
ConclusionsOur research revealed that high levels of vitamin B6 and vitamin D intake were linked to a lower prevalence of kidney stone. With the gradual increase intake of vitamin C, the prevalence of kidney calculi decreased first and then increased. In addition, the co-exposure of nine vitamins is a protective factor for kidney stone disease. (Source: International Urology and Nephrology)

Causal Relationships Between Gut Microbiota, Inflammatory Cells/Proteins, and Subarachnoid Hemorrhage: A Multi-omics Bidirectional Mendelian Randomization Study and Meta-analysis
This study combined various omics approaches with Mendelian randomization analysis, including MR-IVW, MR Egger, MR weight median, and MR weight mode, to generate preliminary results. It also employed reverse Mendelian randomization, treating SAH as the exposure. Finally, a meta -analysis was conducted to summarize these findings. The study found positive correlations between SAH and both GBPA-Pyridoxal 5 phosphate biosynthesis I (OR=1.48, 95% CI, 1.04–2.12) and GBPA-glucose biosynthesis I (OR=0.68, 95% CI, 0.52–0.90). Increased levels of urokinase-type plasma activator were also associated with SAH (OR=1.17, 95% CI, 1....

Biosynthesis of Strained Amino Acids by a PLP-Dependent Enzyme through Cryptic Halogenation
Angew Chem Int Ed Engl. 2024 Mar 22:e202319344. doi: 10.1002/anie.202319344. Online ahead of print.ABSTRACTAmino acids (AAs) are modular building blocks which nature uses to synthesize both macromolecules, such as proteins, and small molecule natural products, such as alkaloids and non-ribosomal peptides. While the 20 main proteinogenic AAs display relatively limited side chain diversity, a wide range of non-canonical amino acids (ncAAs) exist that are not used by the ribosome for protein synthesis, but contain a broad array of structural features and functional groups. In this communication, we report the discovery of the...

Metabolic and physiological adaptations of microalgal growth-promoting bacterium Azospirillum brasilense growing under biogas atmosphere: a microarray-based transcriptome analysis
Arch Microbiol. 2024 Mar 16;206(4):173. doi: 10.1007/s00203-024-03890-z.ABSTRACTUsing microalgal growth-promoting bacteria (MGPB) to improve the cultured microalga metabolism during biotechnological processes is one of the most promising strategies to enhance their benefits. Nonetheless, the culture condition effect used during the biotechnological process on MGPB growth and metabolism is key to ensure the expected positive bacterium growth and metabolism of microalgae. In this sense, the present research study investigated the effect of the synthetic biogas atmosphere (75% CH4-25% CO2) on metabolic and physiological adapt...
