Simultaneous determination of the monosaccharide types and their absolute configurations in polysaccharides based on UPLC-MS/MS.

Analysing monosaccharide composition is an essential step in deciphering polysaccharide structures. However, it presents significant challenges due to the pronounced hydrophilicity and the vast array of monosaccharide isomers. Gas/liquid chromatography, coupled with an aldononitrile acetate derivatisation, has been widely used for monosaccharide composition analysis.

Loss of Cpt1a results in elevated glucose-fueled mitochondrial oxidative phosphorylation and defective hematopoietic stem cells.

Hematopoietic stem cells (HSCs) rely on self-renewal to sustain stem cell potential and undergo differentiation to generate mature blood cells. Mitochondrial fatty acid β-oxidation (FAO) is essential for HSC maintenance. However, the role of Carnitine palmitoyl transferase 1a (CPT1A), a key enzyme in FAO, remains unclear in HSCs.

PRMT5-Mediated ALKBH5 Methylation Promotes Colorectal Cancer Immune Evasion via Increasing CD276 Expression.

Numerous diseases have been connected to protein arginine methylations mediated by protein arginine methyltransferase 5 (PRMT5). Clinical investigations of the PRMT5-specific inhibitor GSK3326595 are currently being conducted, and the results are promising for preventing cancers. However, the detailed mechanism of PRMT5 promoting colorectal cancer (CRC) malignant progression remains unclear.

Impact of Boron Nitride on the Thermoelectric Properties and Service Stability of CuSe.

Improving the thermoelectric performance and service stability is essential for the effective use of cuprous selenide (CuSe). In this study, hexagonal boron nitride (h-BN) was incorporated into nano-CuSe, with the goal of enhancing thermoelectric performance and service stability. It was found that CuSe-0.

HnRNPM modulates alternative splicing in germ cells by recruiting PTBP1.

Background: Heterogeneous nuclear ribonucleoprotein M (HnRNPM) is a key splicing factor involved in various biological processes, including the epithelial‒mesenchymal transition and cancer development. Alternative splicing is widely involved in the process of spermatogenesis. However, the function of hnRNPM as a splicing factor during spermatogenesis remains unknown.
