Enrichment of mRNA and Bisulfite-mRNA Library Preparation for Next-Generation Sequencing

This research aims to study the role of RNA methylation, specifically 5-methylcytosine modification, in pancreatic cancer. The questions we want to answer are how upregulation or downregulation of certain RNA methyltransferase affects cancer cell phenotypes and also, through which RNA substrates. This study provides the comprehensive RNA m5C landscape at a single-base resolution with standardized equipment.

From this study using bisulfite RNA seq, the results links the association of RNA m5C modification with poor differentiation of cancer cells. This should pave the way for future studies in discerning passenger versus disease driver effects of specific m5C in the RNA transcripts. With this technique, we can identify the set of differentially-methylated RNAs that may participate in tumor progression.

Further, single molecule base experiments can provide a more detailed regulatory role of specific RNA m5C.
