Lung cancer is the first cancer-related cause of death worldwide. This is in partially due to therapeutic resistance, which occurs in around 70% of patients, especially those receiving platinum salts, the gold-standard chemotherapy. The massive deregulation of alternative transcript splicing processes observed in many cancers has led to the development of a new class of pharmacological agents aimed at inhibiting the activity of the splicing machinery (spliceosome). The molecular mechanisms by which these inhibitors act remain largely unknown, as do the benefits of using them in combination with other therapies. In this context, our work is focused on an inhibitor of the SRPK1 kinase, a major regulator of the spliceosome.

Osteoporosis is characterized by excessive bone resorption and/or defects in bone formation. Identification of factors promoting osteoblast differentiation may provide potential targets for osteoporosis therapy. Through integral analyses of multiple datasets, NIBAN2 is found to be tightly associated with bone formation and osteoporosis.

To explore the expression of , the subform of protein-based tRNA synthase (), and its prognostic effect on the analysis of gene set enrichment in hepatocellular carcinoma The expressional condition of the gene in tumor tissue samples (374 cases) and adjacent tissue samples (50 cases) of hepatocellular carcinoma patients was compared and recorded by mining the Cancer Genome Atlas database. Hepatocellular carcinoma patients were divided into high expression and low expression groups according to this data. Logistic regression was used to analyze the relationship between and the clinical pathological characteristics of hepatocellular carcinoma patients.

The global dissemination of H5 avian influenza viruses represents a significant threat to both human and animal health. In this study, we conducted a genome-wide siRNA library screening against the highly pathogenic H5N1 influenza virus, leading us to the identification of 457 cellular cofactors (441 proviral factors and 16 antiviral factors) involved in the virus replication cycle. Gene Ontology term enrichment analysis revealed that the candidate gene data sets were enriched in gene categories associated with mRNA splicing via spliceosome in the biological process, integral component of membrane in the cellular component, and protein binding in the molecular function.

The catalytic role of U6 snRNP in pre-mRNA splicing has been well established. In this study, we utilize an antisense morpholino oligonucleotide (AMO) specifically targeting catalytic sites of U6 snRNA to achieve functional knockdown of U6 snRNP in HeLa cells. The data show a significant increase in global intronic premature cleavage and polyadenylation (PCPA) events, similar to those observed with U1 AMO treatment, as demonstrated by mRNA 3'-seq analysis.
