Inhibitory Effect and Mechanism of the Down-Regulation of TRIM32 in Colorectal Cancer.

TRIM32 protein represents a crucial member of TRIM family that is highly expressed in numerous human cancers, and is associated with a poor prognosis. However, the mechanism of TRIM32 in colorectal cancer (CRC) is unclear. The expression of TRIM32 and its prognostic value in CRC were analyzed using The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database.

Hydrogen Incorporation Selectively Modulates the Catalytic Performance of Pd Nanozymes for Cascade-Catalytic Tumor Therapy.

Pd-based nanozymes have emerged as promising alternatives to natural enzymes, but their application is still constrained due to suboptimal activity and poor specificity. As efficient hydrogen storage nanomaterials, the specific implications of implanted hydrogen on the enzyme-mimicking activity of Pd-based nanomaterials remain largely uninvestigated. In this study, we discovered that hydrogenation process significantly enhances the enzyme-like activity of Pd-based nanomaterials, although reaction specificity varies in dependence on the synthetic route of Pd hydrides.

Production of Phenyldiazene Derivatives Using the Biosynthetic Pathway of an Aromatic Diazo Group-Containing Natural Product from an Actinomycete.

The diazo group is an important functional group in organic synthesis because it confers high reactivity to the compounds and has been applied in various chemical reactions, such as the Sandmeyer reaction, Wolff rearrangement, cyclopropanation, and C-N bond formation with active methylene compounds. Previously, we revealed that 3-diazoavenalumic acid (3-DAA), which is potentially produced by several actinomycete species and contains an aromatic diazo group, is a biosynthetic intermediate of avenalumic acid. In this study, we aimed to construct a production system for phenyldiazene derivatives by adding several active methylene compounds to the culture of a 3-DAA-producing recombinant actinomycete.

Effects of fecal microbiota transplantation combined with selenium on intestinal microbiota in mice with colorectal cancer.

Colorectal cancer (CRC) is the third most common cancer in the world. With the development of high-throughput gene sequencing technology, homeostasis imbalance of the intestinal microbiota has been proven to play a key role in the pathogenesis of CRC. Furthermore, fecal bacteria transplantation (FMT) has been shown to alter the intestinal microecology, and is potentially an effective treatment for CRC.

Research on the Effect and Mechanism of Selenium on Colorectal Cancer Through TRIM32.

The intake of selenium (Se) in the human body is negatively correlated with the risk of colorectal cancer (CRC), but its mechanism in the occurrence and development of CRC is not clear. This study aimed to evaluate the therapeutic effect of Se on CRC, and explore the anti-tumor effect of Se supplementation on CRC and its molecular mechanism. In this study, we utilized colony formation assay, cell scratch test, Transwell migration, and flow cytometry to assess cell proliferation, migration, and apoptosis.
