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

Project description: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 .

Expression of tRF & tiRNA in cholangiocarcinoma by RNA sequencing

Project description:The rapid development of high-throughput sequencing is conducive to the discovery of many new theories. The purpose of this study is to explore the differentially expressed of tRF & tiRNA in cholangiocarcinoma by high-throughput sequencing technology. We collected cholangiocarcinoma and adjacent normal tissues from three patients. After RNA extraction and RNA library preparation, we determined the raw data of tRF & tiRNA in cholangiocarcinoma and adjacent normal tissues by high-throughput RNA sequencing. Raw data were generated after sequencing,image analysis,basecalling and quality filtering on lllumina sequencer.Firstly,Q30 was used to perform quality control.The adaptor sequences were trimmed and the adaptor-trimmed-reads(>=16nt) were left by cut adapt software(v1.9.3).Then,the raw counts of each tRF&tiRNA(MINTbasev2.0) was calculated for all samples,defined as the raw expression level soft.The results showed that a total of 20102 tsRNA were detected in the two groups, 9616tsRNA were upregulated and 10486 were downregulated. There were 535 differentially expressed tsRNA in cholangiocarcinoma after edger standardization, of which 241 were upregulated and 294 were downregulated (| log2 (foldchange) | = 1andpvalue < 0.05). This study shows that high-throughput sequencing technology is helpful for us to determine the expression of tRF & tiRNA in cholangiocarcinoma, and to screen out differentially expressed tRF & tiRNA, and further to explore the factors that affect the progress of cholangiocarcinoma.

tRF&tiRNA sequencing of human PTC tissues and corresponding paracancer tissues

Project description:Purpose: To study the expression and potential significance of tRF and tiRNA in PTC (Papillary thyroid carcinoma) by sequencing tRF and tiRNA in PTC tissues and corresponding paracancer tissues of thyroid cancer patients. Methods: Four pairs of PTC tissues and paracancer tissues were collected. Small RNA sequencing was performed on Illumina NexSeq instrument. Results: If P ≤ 0.05, fold change > 1.5 as the cutoff, there were 27 up-regulated tRFs & tiRNAs and 20 down-regulated tRFs & tiRNAs. Conclusions: Among the differentially expressed tRFs & tiRNAs, tiRNA-1:34-Lys-CTT-2 and tRF-1:30-Gly-CCC-3 may be the potential novel regulatory factors.

tRF and tiRNA profiles in lung adenocarcinoma.

Project description:We investigate tRF and tiRNA profiles in lung adenocarcinoma and adjacent tissues using a NextSeq system. Total RNA was extracted from tissues and pretreated to remove the RNA modifications. In patients with lung adenocarcinoma, 338 types of tRFs and tiRNAs were detected via sequencing, 284 of which were not previously reported. Compared with the adjacent tissues, 17 types of tRFs and tiRNAs comprising 34 subtypes were found to be abnormally expressed in lung adenocarcinoma tissues, 20 of which were upregulated and 14 of which were downregulated. Finally, we show that tRF and tiRNA profiles in lung adenocarcinoma and adjacent tissues and identify several dysregulated tRFs and tiRNAs.

Differences in the tRF & tiRNA Profiles of Sperm after Neonatal Sevoflurane Exposure

Project description:The ncRNAs derived from transfer RNAs (tRNAs), such as tRFs (tRNA-derived fragments) and tiRNAs (tRNA halves), play crucial roles in sperm development, maturation, and function, ultimately affecting the health of offspring. To further elucidate the changes in sperm tRF & tiRNA profiles induced by neonatal sevoflurane exposure, we collected sperm from the caudal epididymis of rats and isolated total RNA for tRF & tiRNA sequencing.

High-throughput tRF&tiRNA realtime PCR Array for 10 paired gastric cancer tissues and matched noncancerous tissues

Project description:Total RNA was isolated from ten pairs of matched gastric cancer tissues and non-cancerous tissues. RNAs were then pretreated with rtStar™ tRF&tiRNA Pretreatment Kit (Cat# AS-FS-005, Arraystar) and reverse-transcribed with rtStar™ First-Strand cDNA Synthesis Kit. The synthesed cDNA was used for realtime PCR to detect the differential expression of 353 tRF&tiRNA.
