Alternative splicing (AS) is a crucial mechanism to regulate gene expression and protein complexity. RNA-binding proteins (RBPs) play an important role in regulating abnormal alternative splicing in cancers. However, few resources are available to identify specific RBPs responsible for regulating individual AS event. We have developed the OncoSplicing database for integrative analysis of clinically relevant alternative splicing events in TCGA cancers. Here, we further updated the OncoSplicing database by performing correlation analysis between the splicing and mRNA expression data from the TCGA cancers or GTEx tissues, mapping known RNA-binding motifs and eCLIP-seq peaks to all AS events, conducting splicing analysis for RNA-seq data from RBP perturbation experiments in the ENCODE project, and integrating exon and intron sequences for each AS event. With this updated database, users can easily identify potential RBPs responsible for the queried AS event and obtain sequences to design AS-specific primers and minigene constructs for experiment validation. Overall, compared to the previous version, the substantially updated OncoSplicing database (www.oncosplicing.com) offers a more valuable resource for users to identify RBPs responsible for regulating alternative splicing events in cancers.

RNA-protein interactions orchestrate hundreds of pathways in homeostatic and stressed cells. We applied an RNA-protein interactome capture method called protein cross-linked RNA extraction (XRNAX) to shed light on the RNA-bound proteome in dysmyelination. We found sets of canonical RNA-binding proteins (RBPs) regulating alternative splicing and engaged in the cytoplasmic granules to be perturbed at the level of their RNA interactome.

Post-transcriptional regulation of behavior plasticity in social insects.

Curr Opin Insect Sci

December 2024

Department of Entomology, College of Plant Protection, China Agricultural University, Beijing, China. Electronic address:

Social insects often show remarkable behavioral plasticity, which is closely associated with their respective castes. The underpinnings of this plasticity are complex, involving genetic differences among individuals within a colony and regulation of gene expression at multiple levels. Post-transcriptional regulation, which increases the complexity of the transcriptome, plays a crucial role in the multilayer regulatory network that influences social insect behavior.

Heat stress affects various components of photosynthetic machinery of which Rubisco activation inhibition due to heat sensitive Rubisco activase (RCA) is the most prominent. Detailed comparison of RCA coding genes identified a tandem duplication event in the grass family lineage where the duplicated genes showed very different evolutionary pattern. One of the two genes showed high level of sequence conservation whereas the second copy, although present only 1.

Validation and in silico function prediction of circtial1 as a novel marker of abnormal lung development in nitrofen-induced congenital diaphragmatic hernia (CDH).

Pediatr Surg Int

December 2024

Division of Pediatric Surgery, Department of Surgery, Max Rady College of Medicine, University of Manitoba, and Children's Hospital Research Institute of Manitoba, AE402-820 Sherbrook Street, Winnipeg, MB, R3A 1S1, Canada.

Purpose: Circular RNAs (circRNAs) are stable, non-coding RNAs with tissue- and developmental-specific expression making them suitable biomarkers for congenital anomalies. Current circRNA discovery pipelines have focused on human and mouse. We aim to bridge this gap by combining bioinformatics resources and used circtial1 as a model candidate in the nitrofen rat model of congenital diaphragmatic hernia (CDH).
