Analysis of exosomal miRNAs upon irradiation in pancreatic cancer cells

We used miRNA-seq and bioinformatics to analyze and annotate the expression profiles exosomal miRNAs in pancreatic cancer cells after radiation, compared with the unirradiated cells. A total of 481 miRNAs were identified, and 284 miRNAs were annotated in miRBase. There were 22 filtered differentially expressed miRNAs (9 for up-regulated and 13 for down-regulated, fold change > 2, p-value < 0.05). This study provides the results of exosomal miRNA change in pancreatic cancer cells after radiation. Examination of small RNA profiles of pancreatic cells-derived exosomes by NGS
