RNA-binding proteins (RBPs) are key regulators of posttranscriptional processes such as RNA maturation, localization, turnover and translation. Despite their dysregulation in various diseases including cancer, the landscape of RBP expression in human cancer has not been well elucidated. Here, we built a comprehensive expression landscape of 1504 RBPs across 16 human cancer types, which revealed that RBPs are predominantly upregulated in tumours and this phenomenon is affected by the tumour immune subtypes and microenvironment. Across different cancer types, 109 RBPs are consistently upregulated while 41 RBPs are consistently downregulated. These up-regulated and down-regulated RBPs show distinct molecular characteristics and prognostic effects, whereas their dysregulation is mediated by distinct cis/trans-regulatory mechanisms. Finally, we validated one candidate PABPC1L that might promote colon tumorigenesis by regulating mRNA splicing. In summary, we built a comprehensive expression landscape of RBPs across different cancer types and identified consistently dysregulated RBPs which could be novel targets for developing broad-spectrum anticancer agents.

Database of manually annotated protein complexes from mammalian organisms. Annotation includes protein complex function, localization, subunit composition, literature references and more. All information is obtained from individual experiments published in scientific articles, but data from high-throughput experiments is excluded.
The majority of protein complexes in CORUM originates from man (65%), followed by mouse (14%) and rat (14%).
Database of known and predicted protein interactions. The interactions include direct (physical) and indirect (functional) associations and are derived from four sources: Genomic Context, High-throughput experiments, (Conserved) Coexpression, and previous knowledge. STRING quantitatively integrates interaction data from these sources for a large number of organisms, and transfers information between these organisms where applicable. The database currently covers 5''214''234 proteins from 1133 organisms. (2013)

View all literature mentionsIntegrated database resource consisting of 16 main databases, broadly categorized into systems information, genomic information, and chemical information. In particular, gene catalogs in completely sequenced genomes are linked to higher-level systemic functions of cell, organism, and ecosystem. Analysis tools are also available. KEGG may be used as reference knowledge base for biological interpretation of large-scale datasets generated by sequencing and other high-throughput experimental technologies.
