tRF & tiRNA sequencing of intestinal biopsies from IBS-D patients

Purposes: To investigate the epigenetic mechanism of IBS-D(Irritable Bowel Syndrome with Diarrhea) by tRF & tiRNA sequencing in intestinal biopsies of IBS-D patients and healthy volunteers Methods: Five IBS-D and five healthy volunteers were screened, and biopsies were taken under colonoscopy. Small RNA sequencing was performed on Illumina NexSeq instrument Results:If P < 0.05, fold change > 1.5 as the cutoff, there were 14 up-regulated tRFs & tiRNAs and 14 down-regulated tRFs & tiRNAs. Conclusions:There were 14 up-regulated tRFs & tiRNAs and 14 down-regulated tRFs & tiRNAs in intestinal tissues of IBS-D . Overall design: tRF & tiRNA sequencing of intestinal biopsies from five IBS-D patients and five healthy volunteers
