Article Abstract
Background: Aberrant splicing has been closely associated with human cancer, though the precise underlying mechanisms linking the two remain not fully understood. Investigating the role of splicing factors in cancer progression may aid in the development of targeted therapies for dysregulated splicing, thereby opening up new avenues for cancer treatment. RNA-binding motif 4 (RBM4) has been identified as a critical participant in the condensin II complex, which is involved in chromosome condensation and stabilization during mitosis. Its significance in tumors is currently gaining attention. The genetic characteristics of RBM4 suggest its potential to elucidate the malignant progression of tumors in a broader context, encompassing various types of cancer, known as pan-cancer.
Methods: This study aims to comprehensively explore the potential function of RBM4 in pan-cancer by leveraging existing databases such as The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx).
Results: RBM4 is found to be overexpressed in almost all tumors and exhibits significant prognostic and diagnostic efficacy. The correlation between RBM4 and immune signatures, including immune cell infiltration and immune checkpoint genes, indicates that RBM4 could serve as a guiding factor for immunotherapy.
Conclusions: As a member of the pan-oncogene, RBM4 has the potential to become a biomarker and therapeutic target for various malignant tumors, offering novel possibilities for precision medicine.

Background: This study investigates the shared genetic architecture between anxiety disorders (ADs) and ten autoimmune diseases: rheumatoid arthritis (RA), Crohn's disease (CD), ulcerative colitis (UC), psoriasis (PsO), mixed connective tissue disease (MCTD), graves' disease (GD), ankylosing spondylitis (AS), Sjögren's syndrome (SS), multiple sclerosis (MS), and systemic lupus erythematosus (SLE). It aims to identify shared risk loci, key immune traits, and genetic mechanisms contributing to the pathophysiology of these conditions.
Methods: Utilizing GWAS summary data from IEU Open GWAS and Finngen R11, we identified significant genetic correlations between ADs and autoimmune diseases.

Emerging evidence demonstrates that cryptic translation from RNAs previously annotated as noncoding might generate microproteins with oncogenic functions. However, the importance and underlying mechanisms of these microproteins in alternative splicing-driven tumor progression have rarely been studied. Here, we show that the novel protein TPM3P9, encoded by the lncRNA tropomyosin 3 pseudogene 9, exhibits oncogenic activity in clear cell renal cell carcinoma (ccRCC) by enhancing oncogenic RNA splicing.

Brain-derived neurotrophic factor (BDNF) plays important roles in brain development and neural function. Constitutive knockout of the splicing regulator RBM4 reduces BDNF expression in the developing brain and causes cerebellar hypoplasia, an autism-like feature. Here, we show that Rbm4 knockout induced intron 6 retention of Hsf1, leading to downregulation of HSF1 protein and its downstream target BDNF.

Hypoxia is a critical microenvironmental factor that induces tumorigenesis and cancer progression, including metastasis. The highly dynamic nature of the extracellular matrix (ECM) plays a crucial role in metastasis. Collagens are the predominant component of structural proteins embedded within the ECM.
