Tens of thousands of internal mRNA m7G sites have been identified within mammalian transcriptomes, and a single resource to best share, annotate and analyze the massive m7G data generated recently is sorely needed. RESULTS We report here m7GHub, a comprehensive online platform for deciphering the location, regulation and pathogenesis of internal mRNA N7-methylguanosine. The m7GHub consists of four main components, including the first internal mRNA m7G database containing 44,058 experimentally-validated internal mRNA m7G sites, a sequence-based high-accuracy predictor, the first web server for assessing the impact of mutations on m7G status, and the first database recording 1,218 disease-associated genetic mutations that may function through regulation of m7G methylation. Together, m7GHub will serve as a useful resource for research on internal mRNA m7G modification. AVAILABILITY m7GHub is freely accessible online at www.xjtlu.edu.cn/biologicalsciences/m7ghub.

One important quantitative property is differential usage of Ig genes between biological conditions. Yet, most analyses for differential Ig gene usage are performed qualitatively or with inadequate statistical methods. Here we introduce IgGeneUsage, a computational tool for the analysis of differential Ig gene usage. IgGeneUsage employs Bayesian inference with hierarchical models to analyze complex gene usage data from high-throughput sequencing experiments
