Summary: Diabetic retinopathy (DR) is a major complication of diabetes mellitus, and anti-vascular endothelial growth factor (VEGF) therapy is commonly used for treatment. However, many DR patients do not respond well to this treatment. This study used proteome profiling to identify dysregulations in metabolic, signaling, and immune networks in the vitreous humor of PDR patients. The impaired ADAM10-AXL axis was proposed as a driver of retinal angiogenesis, and restoring aberrant ectodomain shedding was suggested as a potential treatment strategy for PDR.

Summary: The engineered obligate anaerobic Salmonella typhimurium strain YB1 has the potential to repress tumor growth and metastasis, with a distinct immune response identified through temporal proteome profiling. This includes the activation of innate immune responses, phagocytosis, and recruitment of T cells leading to tumor shrinkage. Temporal proteome profiling can systematically reveal the YB1 induced immune responses in tumors, showing great promise for elucidating the mechanism of bacteria-mediated cancer immunotherapy.

Summary: O-GlcNAcylation, a simple but essential protein post-translational modification, plays critical roles in cellular processes and is closely associated with various diseases. However, the low stoichiometry and reversibility properties of O-GlcNAcylation pose challenges for system-wide research. In this study, a novel method combining multi-comparative thermal proteome profiling was developed for O-GlcNAc transferase (OGT) substrate discovery. By profiling and comparing the melting curves of proteins under different treatments, proteins with significantly altered stabilities induced by OGT and uridine-5'-diphosphate N-acetylglucosamine were identified and new O-GlcNAcylated proteins were uncovered.

Summary: Chronic BK polyomavirus (BKPyV) infection is considered a potential oncogenic factor for urothelial carcinoma (UC) in renal transplant recipients. Integration sites between human and BKPyV genomes were enriched with microhomologies, and viral insertional integration led to fusion sequences of 75 human genes, with 15 genes showing statistical association with UC based on expression analysis. These findings suggest a potential mechanism of viral-driven carcinogenesis in BKPyV-related UC.

Summary: To ensure genetic stability, cells must duplicate their complement of chromosomes prior to cell division. This process involves replicating chromosomal DNA and re-establishing the chromatin environment. The duplication of chromatid pairs must remain coupled until cell division to ensure equal segregation of genetic material. Cyclin-dependent kinases (CDK) control the regulation of chromosome duplication. CDK also activates Dbf4-dependent kinase (DDK), which facilitates DNA replication activation and coordination with chromatin re-establishment and chromatid coupling. This review discusses the outsourcing of these activities by CDK to DDK to ensure chromosome maintenance during cell division.

Summary: The RNA-binding ARS2 protein is involved in both early RNA polymerase II (RNAPII) transcription termination and transcript decay. It binds to ZC3H4 to recruit it to chromatin for RNAPII termination and forms a direct connection to the NEXT complex for rapid degradation of the RNA. ARS2 functions differently at CPA-instructed termination sites.

Summary: Cilia are important cellular organelles for signaling and motility and are constructed via intraflagellar transport (IFT). RabL2 localizes to the basal body of cilia via an interaction with CEP19 before downstream association with the IFT machinery. Reconstituted pentameric IFT complex containing IFT81/74 enhances the GTP hydrolysis rate of RabL2. Structural models of RabL2-containing IFT complexes validate the architectural understanding of RabL2 incorporation into the IFT complex.

Summary: The RNA exosome is a versatile ribonuclease that functions in the nucleoplasm of mammalian cells. It is assisted by the nuclear exosome targeting (NEXT) complex and the poly(A) exosome targeting (PAXT) connection. The PAXT pathway targets short adenylated RNAs through the ZFC3H1 component, which interacts directly with ARS2. In addition, ZC3H18 competes with PAXT and antagonizes its activity.
