Abstract 5-Methylcytosine (m 5 C) is a posttranscriptional RNA modification participating in many critical bioprocesses, but its functions human cancer remain unclear. Here, by detecting the transcriptome-wide m C profiling esophageal squamous cell carcinoma (ESCC), we showed increased methylation ESCC tumors due to overexpressed methyltransferase NSUN2. Aberrant expression of NSUN2 was positively regulated E2F Transcription Factor 1 (E2F1). High levels predicted poor survival patients....

Background: Our previous study has demonstrated an oncogenic role of PIWI-interacting RNA-54265 (piR-54265) in colorectal cancer (CRC). Here, we investigate whether it can be a blood biomarker for population screening and clinical applications. Methods: Serum piR-54265 levels were determined by digital PCR method 209 cancer-free healthy controls, 725 patients with CRC, 1303 other types digestive 192 benign tumors. A prospective case-control analysis was conducted to assess the predictive...

Pseudogenes may play important roles in cancer. Here, we explore the mechanism and function of a pseudogene WTAPP1 progress pancreatic ductal adenocarcinoma (PDAC). RNA was significantly elevated PDAC associated with poor prognosis patients. Overexpression promoted proliferation invasiveness vitro vivo. Mechanistically, N6-methyladenosine (m6A) modification stabilized via CCHC-type zinc finger nucleic-acid binding protein (CNBP), resulting increased levels cells. Excessive bound its...

The tumorigenic mechanism for pancreatic ductal adenocarcinoma (PDAC) is not clear, although chronic inflammation implicated. Here, we identified an inflammatory cytokine–regulated transfer RNA–derived (tRNA-derived) fragment, tRF-21-VBY9PYKHD (tRF-21), as a tumor suppressor in PDAC progression. We found that the biogenesis of tRF-21 could be inhibited by leukemia inhibitory factor and IL-6 via splicing SRSF5. Reduced promoted AKT2/1-mediated heterogeneous nuclear ribonucleoprotein L (hnRNP...

Abstract The molecular mechanism underlying pancreatic ductal adenocarcinoma (PDAC) malignancy remains unclear. Here, we characterize a long intergenic non-coding RNA LINC00842 that plays role in PDAC progression. expression is upregulated and induced by high concentration of glucose via transcription factor YY1. binds to prevents acetylated PGC-1α from deacetylation deacetylase SIRT1 form PGC-1α, an important co-factor regulating cellular metabolism. overexpression causes metabolic switch...

Thiol groups on cysteines can undergo multiple post-translational modifications (PTMs), acting as a molecular switch to maintain redox homeostasis and regulating series of cell signaling transductions. Identification sophistical protein cysteine is crucial for dissecting its underlying regulatory mechanism. Instead time-consuming labor-intensive experimental method, various computational methods have attracted intense research interest due their convenience low cost. Here, we developed the...

N6-methyladenosine (m6A) is the most prevalent RNA modification, and effect of its dysregulation on esophageal squamous cell carcinoma (ESCC) development remains unclear. Here, by performing transcriptome-wide m6A sequencing in 16 ESCC tissue samples, we identified key roles TNFRSF1A (also known as TNFR1)-mediated MAPK NF-κB activation ESCC. Mechanistically, a functional protein involved methylation, ATXN2, that augments translation binding to m6A-modified mRNA. Upregulation level, vital...

Abstract In recent years, long noncoding RNAs (lncRNAs) have been demonstrated to be important tumor‐associated regulatory factors. LncRNA growth arrest‐specific transcript 5 (Gas5) acts as an anti‐oncogene in most cancers. Whether Gas5 oncogene or hepatocellular carcinoma (HCC) remains unclear. the present study, expression and role of HCC were investigated vitro vivo. Lower levels determined tissues cells by quantitative reverse transcription‐polymerase chain reaction. Overexpressed Gas...

In this study, we aimed to expand the current miRNA data bank of Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) regarding its potential value for further genetic and genomic use in species. High-throughput small RNA sequencing successfully captured 140 miRNAs from a selfing family harboring vigor depressed progeny. Strikingly, 75.7% (n = 106) these have not been documented previously, most 105) them belong novel set with 6858 putative target genes. The new datasets were then integrated...
