“…Few studies have reported the role of GUSBP11 and CTDHUT in cancer. Recently, Cao et al [36] reported that GUSBP11 was significantly associated with survival of patients with head and neck squamous cell carcinoma. We then chose FAM49B-AS to explore its cytological function according to the coding ability, transcript properties of candidate lncR-NAs, and the capability of tracking disease.…”

Background Although long non-coding RNAs (lncRNAs) are regarded as useful plasma-based biomarkers for cancer detection, the potential diagnostic value of lncRNAs in gastric cancer (GC) remains unclear. Methods To screen promising lncRNAs biomarkers for GC, we performed genome-wide lncRNA microarray assay between five GC cases plasma and matched healthy controls plasma. The expression of candidate plasma-related lncRNAs were validated in two-phase validation of 446 subjects. The receiver operating characteristic curve was constructed for evaluating diagnostic accuracy. We also determined the origin and stability of plasma lncRNAs, and investigated biological effects of candidate lncRNAs on cellular phenotypes. Results A total of 3878 lncRNAs were expressed differentially in GC plasma, among which the top 10 up-regulated lncRNAs were selected for further validation. A two-stage validation revealed that plasma levels of three lncRNAs (FAM49B-AS, GUSBP11, and CTDHUT) were significantly higher in GC plasma as compared with healthy controls (P < 0.05), and the combined area under curve of these lncRNAs was 0.818 (95% CI 0.772-0.864). Moreover, these lncRNAs were stable and detectable in human plasma, and also enriched in extracellular fluid. The expression levels of all three lncRNAs dropped significantly on day 10 after radical surgery compared with preoperative levels (P < 0.05). Also, lncRNA FAM49B-AS significantly promoted GC cell viability and invasion. Conclusions Plasma lncRNA FAM49B-AS, GUSBP11 and CTDHUT have a strong potential to serve as noninvasive biomarkers for GC diagnosis.

“…LncRNAs also have significant biological functions in modulating gene at transcriptional, post-transcriptional and chromosomal levels [8]. LncRNAs participate in physiological processes of cell-type determination and tissue homeostasis, and it has been proved that LINC00963 was involved in the prostate cancer transition from androgen-dependent to androgen-independent and metastasis via the epidermal growth factor receptor (EGFR) signaling pathway [9].…”

Background/Aims: Chronic renal failure (CRF) is usually associated with chronic diseases such as congestive heart failure and diabetes mellitus, the prevalence of which is increased with age. This study is designed to investigate the role of long intergenic non-coding RNA (lincRNA) LINC00963 in renal interstitial fibrosis (RIF) and oxidative stress (OS) of CRF via the forkhead box O (FoxO) signaling pathway. Methods: Microarray data and annotated probe files related to CRF were downloaded by retrieving Gene Expression Omnibus (GEO) database to screen differentially expressed lncRNA. Multi Experiment Matrix (MEM) website and dual-luciferase reporter gene assay were used to predict and verify the target gene of LINC00963, and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis to identify the major signaling pathways involved. A total of 60 Wistar male rats were randomly selected and divided into the sham (n = 10) and model (n = 50) groups. Five rats in the sham group and thirty rats in the model group were sub-categorized into the control, blank, negative control (NC), LINC00963 vector, si-LINC00963, si-FoxO3, and si-LINC00963 + si-FoxO3 groups (n = 5). Reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blot analysis were performed to evaluate the expressions of LINC00963, FoxO3a, TGF-β1, FN, GSH-PX, Bax, and Bcl-2. Measurement of changes in OS indexes including BUN, MDA, GSH-Px, SOD, and Na⁺-K⁺-ATP were conducted. Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of inflammatory factors including TNF-α, IL-6, ICAM-1 and FN. TUNEL staining was performed to evaluate cell apoptosis. Results: LINC00963 was highly expressed in CRF rats and FoxO3 was predicted and then verified as a target gene of LINC00963. FoxO3 gene participated in the FOXO signaling pathway. Compared with the blank and NC groups, there were significantly decreased expressions of LINC00963, TGF-β1, FN, and Bax in the si-LINC00963 group, while increased expressions of GSH-PX, FoxO3a, and Bcl-2. The vitality values of BUN and MDA in the si-LINC00963 group declined, while enzymatic activities of GSH-Px, SOD and Na⁺-K⁺-ATP elevated in comparison to the blank and NC groups. The levels of TNF-α, IL-6, ICAM-1 and FN, and cell apoptosis rate in the si-LINC00963 group decreased in comparison to the blank and NC groups. All the results in the si-LINC00963 group were opposite in the LINC00963 vector and si-FoxO3 groups. Conclusion: Taken together, we conclude that down-regulation of LINC00963 suppresses RIF and OS of CRF by activating the FoxO signaling pathway.

“…Long noncoding RNAs (lncRNAs) represent a group of nonprotein-coding transcripts with nucleotides lengths of 200 or more that have been widely reported to have crucial roles in both tumor development and progression (10). lncRNAs have notable roles in the modulation of genes at transcriptional, posttranscriptional, and chromosomal levels, in addition to other various vital biologic functions (11). Studies have indicated that lncRNAs modulate gene expression by binding to chromatin regulators and interfering RNAs, by which they are able to exert their effects on cellular responses (12).…”

Long noncoding RNA LINC00261 induces chemosensitization to 5‐fluorouracil by mediating methylation‐dependent repression of DPYD in human esophageal cancer

Approximately 85% of a single administered dose of 5-fluorouracil (5-FU) will be degraded by dihydropyrimidine dehydrogenase (DYPD). Studies have highlighted a link between the complete or partial loss of DYPD function and clinical responses to 5-FU; however, the underlying molecular basis of DPD deficiency remains poorly understood. Hence, the aim of the present study was to evaluate the prevailing hypothesis which suggests that overexpression of LINC00261 possesses the ability to modulate the methylation-dependent repression of DPYD, ultimately resulting in an elevation of the sensitivity of human esophageal cancer cells to 5-FU. LINC00261 levels were initially quantified, followed by analysis of DYPD methylation within the cancerous tissues collected from 75 patients diagnosed with esophageal cancer undergoing 5-FU-based adjuvant chemotherapy. In an attempt to determine the levels of LINC00261 related to the esophageal cancer cell resistance to 5-FU and to identify the interaction between the levels of LINC00261 and methylation of the DYPD promoter, esophageal cancer cells TE-1 and -5 were prepared, in which LINC00261 and the 5-FU-resistant TE-1 and -5 cells were overexpressed. The levels of LINC00261 were reduced among the cancerous tissues obtained from patients exhibiting resistance to 5-FU. Overexpression of LINC00261 was determined to dramatically inhibit proliferation and resistance to apoptosis among 5-FU-resistant TE-1 and -5 cells, whereas silencing of LINC00261 was determined to enhance proliferation and resistance to apoptosis among the TE-1 and -5 cells. DPYD, a confirmed target of LINC00261, displayed a greater incidence of DNA methylation among patient's sensitive to 5-FU. A key finding revealed that overexpressed LINC00261 could increase the methylation of the DPYD promoter through the recruitment of DNA methyltransferase (DNMT), which, in turn, acts to decrease DPYD activity in 5-FU-resistant TE-1 cells, whereas a reversible change was recorded once the demethylation reagent 5-aza-2'-deoxyctidine was employed to treat the 5-FU-resistant TE-1 cells. Taken together, the results of the study provided evidence emphasizing the distinct antitumor ability of LINC00261 in cases of esophageal cancer, which was manifested by overexpression of LINC00261 detected to increase the sensitivity of human esophageal cancer cells to 5-FU by mediating methylation-dependent repression of DPYD. Our study highlighted the potential of LINC00261 as a novel target capable of improving the chemotherapeutic response and survival of patients with esophageal cancer.-Lin, K., Jiang, H., Zhuang, S.-S., Qin, Y.-S., Qiu, G.-D., She, Y.-Q., Zheng, J.-T., Chen, C., Fang, L., Zhang, S.-Y.
