Project Summary Dynamic mRNA modi¿cations, such as the m6A-dependent regulation at the mRNA level, add a critical new dimension to post-transcriptional regulation of gene expression. The rapid development of sequencing technologies has transformed the ¿eld of epitranscriptomics studies by resulting in the successful pro¿ling transcriptome-wide RNA modi¿cations under different states and conditions. They hold the promise to reveal regulatory machinery of RNA modi¿cations, which contributes to almost every phase of mRNA metabolism and function, thereby impacting diverse biological processes. How- ever, analytical developments in epitranscriptomics lag far behind the pace of technological discovery, and the bioinformatic infrastructure available for epitranscriptomic studies remains limited. The overar- ching goal of this proposal is to address three most pressing challenges facing pro¿ling and interpreting epitranscriptomics. Speci¿cally, we will achieve the following aims: Aim1. Develop statistical methods for RNA modi¿cation detection at single nucleotide resolution. Aim 2. Develop computational meth- ods for cell type-speci¿c methylation analysis. Aim 3. Develop web servers that enable integrating RNA modi¿cation with a rich catalog of genomics features. All the methods will be implemented in user-friendly software and disseminated to the scienti¿c community. Successful achievement of all aims will dramatically increase the power of epitranscriptomes analysis, leading to better understand- ing of regulatory mechanisms in RNA modi¿cations and their implications in phenotypes and human diseases.
