The depolymerized products and oligosaccharide fractions from sea cucumber fucosylated glycosaminoglycans (FGs) are promising anticoagulant candidates, and more novel FG-derived oligosaccharides from low-priced sea cucumbers are expected to be obtained. This study isolated 5-12 oligomers (OF1-OF3) with unusual branches from β-eliminative depolymerized products of FG (CqFG). Detailed NMR analyses showed that OF1-OF3 consisted of a chondroitin 4,6-sulfates backbone and some sulfated fucosyl branches (FucS), including monosaccharides (α-l-Fuc, α-l-Fuc, α-l-Fuc, α-l-Fuc, and α-l-Fuc) and a disaccharide D-Gal-α1,3-l-Fuc with the ratio of ~36:35:10:7:3:9, attached to the C-3 position of β-d-GlcA or its derivatives, such as α-l-Δ4,5GlcA and β-d-GlcA-ol.

Estimating the post mortem interval (PMI) is a crucial and contentious issue in forensic research, particularly in criminal cases. Traditional methods for PMI estimation are limited by constraints and inaccuracies. Circular RNA (circRNA), formed through exon or intron looping to create a complete circular structure without a 5' end cap and a 3' poly(A) tail, exhibits exceptional stability, abundance, and tissue-specific characteristics that make it potentially valuable for PMI estimation.

A disintegrin and metalloproteinase domain 10 (ADAM10), a member of the ADAM family, is a cellular surface protein with potential adhesion and protease/convertase functions. The expression regulations in cancers by natural products [adenosine (AD) and its analogs, cordycepin (CD), and N6, N6-dimethyladenosine (m A)], and immune regulation are unclear. As results, AD, CD, and m A inhibited ADAM10 expression in various cancer cell lines, indicating their roles in anti-cancer agents.

Article Synopsis
  • - Breast cancer is the most common cancer in women, and the protein TRIM28 (RNF96) has various important roles in cancer biology, including DNA repair and supporting cancer progression, but its specific effects on breast cancer are not well understood.
  • - In a study using multiple analysis methods, researchers found that TRIM28 is overexpressed in breast invasive carcinoma (BRCA) tissues compared to normal tissues, indicating a link to the disease's aggressiveness and potential as a long-term survival predictor for severe types of breast cancer.
  • - The study also showed that cordycepin (CD) can reduce TRIM28 levels and inhibit breast cancer progression in mice, suggesting that TRIM28 could be a target for developing new

Nonsyndromic hearing loss (NSHL) is a genetically diverse, highly heterogeneous condition characterised by deafness, and Gasdermin E (GSDME) variants have been identified as directly inducing autosomal dominant NSHL. While many NSHL cases associated with GSDME involve the skipping of exon 8, there is another, less understood pathogenic insertion variant specifically found in Chinese pedigrees that causes deafness, known as autosomal dominant 5 (DFNA5) hearing loss. In this study, we recruited a large Chinese pedigree, conducted whole-exome and Sanger sequencing to serve as a comprehensive clinical examination, and extracted genomic DNA samples for co-segregation analysis of the members.
