Project description:tRNA-derived fragments (tRFs) are new noncoding RNAs, and recent studies have shown that tRNAs and tRFs have important functions in cell metabolism via posttranscriptional regulation of gene expression. However, whether tRFs regulate cellular metabolism of the anterior cruciate ligament (ACL) remains elusive. The aim of this study was to investigate the role and action mechanism of tRFs in ACL cell metabolism. Arraystar_tRF&tiRNA was used to determine tRFs and tiRNA expression profiles in human OA ACL cells and NA ACL cells。

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.

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.

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 .

Project description:Purposes: To investigate the biological function of tRF in breast cancer by tRF and tiRNA sequencing Methods: Breast cancer tissue samples and matched non-tumor adjacent tissues were obtained from five patients. Small RNA sequencing was performed on Illumina NexSeq instrument Results: If P ≤ 0.05, fold change ≥ 2 as the cut off, there were 3 up-regulated tRFs & tiRNAs and 13 down-regulated tRFs & tiRNAs. Conclusions:There were 3 up-regulated tRFs & tiRNAs and 13 down-regulated tRFs & tiRNAs in breast cancer tissue samples and matching adjacent tissue samples

Project description:Purpose: To explore the expression and biological functions of tRFs & tiRNAs in BALB/c mice with AD. Method: tRFs/tiRNAs profiles of control mice skin and 2,4-dinitrochlorobenzene(DNCB)- induced mice skin were generated by the Arraystar Mouse Small RNA Arrays. qRT–PCR validation was performed using SYBR Green assays. Results: There were 676 tRFs/tiRNAs that were aberrantly expressed in BALB/c mice with AD; 298 were upregulated and 378 were downregulated. tRF5-20-GluCTC-1, 5'tiRNA-33-ProTGG-4, 5'tRF-GluTTC, and mt-tRF3a-ProTGG were significantly expressed and confirmed with qRT–PCR, demonstrating the high degree of sensitivity of the Small RNA microarray technology. Conclusion: The pathogenesis of AD may be related with the differential expression of tRFs/tiRNAs. These findings may provide new perspectives for elucidating the molecular mechanisms and future treatments for AD.
