Core Tip
Core Tip: Neoadjuvant chemoradiotherapy (nCRT) is the standard of care for the management of locally advanced rectal cancer; however, chemoresistance remains a life-threatening problem in patients with colorectal cancer. In this study, we used RNA sequencing to identify the expression profiles of plasma exosomal microRNAs (miRNAs) in two dimensions, according to treatment response (poor/good responders) and treatment course (pre/post-nCRT). Exosome hsa-miR-483-5p was upregulated in good responders post-nCRT and was chosen for further analysis. A network of hsa-miR-483-5p/MAPK3/RNF 165/ZNF417 was constructed using bioinformatic analysis in terms of survival, stage, and drug sensitivity. This study provides insights into the mechanism of chemoresistance in terms of exosomal miRNAs. However, further research is required within the framework of our established miRNA-mRNA network.
