Regulating Tumor Metabolic Reprogramming with Biomimetic Co‐Delivery of Simvastatin and Kynureninase for Immunotherapy

Advanced Science, EarlyView.
After the intravenous injection of biomimetic and pH/ROS‐responsive PTSK@CRM, the nanoparticles can be accumulated in tumors and release Sim and KYNase to inhibit the tumor growth, regulate the metabolism of cholesterol and Kyn, and reverse the immunosuppressive tumor microenvironment.

Bacterial DNA Methylation and Methylomes.

Advances in Experimental Medicine and Biology, 2016
Formation of C5-methylcytosine, N4-methylcytosine, and N6-methyladenine in bacterial genomes is postreplicative and involves transfer of a methyl group from S-adenosyl-methionine to a base embedded in a specific DNA sequence context. Most bacterial DNA methyltransferases belong to restriction-modification systems; in addition, "solitary" or "orphan ...

Preparing Bacterial Genomic DNA

Cold Spring Harbor Protocols, 2022
We describe two alternative procedures for purifying bacterial chromosomal DNA. The first procedure incorporates the use of a commercial kit based on silica membrane technology. This approach relies on the selective binding of DNA to a silica-based column in the presence of chaotropic salts (guanidine salts).

Chloramphenicol damages bacterial DNA

Biochemical and Biophysical Research Communications, 1977
L(+)-threo-chloramphenicol induces reversion of His−Salmonella typhimurium strains TA100 and TA1535 in the conventional Ames' assay without microsomal activation. Any mutagenicity of D(−)-threo-chloramphenicol was masked by toxicity. Similarly, a sensitive fluctuation test showed mutagenesis with L(+)-threo-chloramphenicol at concentrations of 0.5 μM ...
