• RNF114, PARP1 Trapping, and BRCA Synthetic Lethality

  2026-08-13

  Li et al. identified RNF114 as a PARylation-dependent E3 ubiquitin ligase that regulates PARP1 removal from DNA lesions. Their work shows that nimbolide inhibits this pathway, intensifies PARP1 trapping, selectively kills BRCA-mutated cancer cells, and can overcome both intrinsic and acquired resistance to PARP inhibitors.

• Gut Dysbiosis and Docetaxel Resistance in Prostate Cancer

  2026-08-08

  Zhong et al. connect antibiotic-associated gut dysbiosis with prostate cancer progression and reduced Docetaxel sensitivity through increased gut permeability, intratumoral lipopolysaccharide, and activation of the NF-κB–IL6–STAT3 axis. The study combines mouse models, fecal microbiota transplantation, 16S rRNA profiling, mechanistic assays, and patient samples to identify Proteobacteria enrichment as a candidate marker of advanced disease.

• Penicillin G Sodium: Applied Research Workflows

  2026-08-07

  Penicillin G Sodium is a natural penicillin antibiotic for controlled Gram-positive selection, infection-model benchmarking, and contamination management—not a universal cell-culture additive.
