Abstract
Disulfidptosis is a newly discovered form of cell death. Not yet clearly classified as programmed cell death or accidental cell death. This study aimed to create a novel disulfidptosis-related lncRNA index (DLI) that can be used to predict survival and chemotherapy drugs sensitivity in patients with cervical cancer. First of all, we found lncRNAs associated with disulfidptosis between cervical cancer tissues and normal tissues. By LASSO-Cox analysis, overlapping lncRNAs were then used to construct lncRNA index associated with disulfidptosis, which can be served to predict the prognosis of patients with CC, especially the chemotherapy drugs sensitivity. ROC curves and PCA based on DLI and clinical signatures were developed and demonstrated to have good predictive potential. In addition, differences in immune cell subset infiltration and differences in immune checkpoint expression between high-DLI and low-DLI groups were analyzed, and we investigated the relationship between the DLI and tumor mutation burden (TMB). In summary, we constructed a lncRNA prediction index associated with disulfidptosis. This has important clinical implications, including improving the predictive value of cervical cancer patients and providing a biomarker for cervical cancer guiding individualized treatment.

Comprehensive analysis of cuproptosis-related long noncoding RNA for predicting prognostic and diagnostic value and immune landscape in colorectal adenocarcinoma. Hum Genomics 2023; 17:22. [PMID: 36915193 PMCID: PMC10009981 DOI: 10.1186/s40246-023-00469-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Accepted: 03/04/2023] [Indexed: 03/16/2023] Open
Abstract
BACKGROUND Cuproptosis, as a copper-induced mitochondrial cell death, has attracted extensive attention recently, especially in cancer. Although some key regulatory genes have been identified in cuproptosis, the related lncRNAs have not been further studied. Exploring the prognostic and diagnostic value of cuproptosis-related lncRNAs (CRLs) in colon adenocarcinoma and providing guidance for individualized immunotherapy for patients are of great significance. RESULTS A total of 2003 lncRNAs were correlated with cuproptosis genes and considered as CRLs. We screened 33 survival-associated CRLs and established a prognostic signature base on 7 CRLs in the training group. The patients in the low-risk group had better outcomes in both training group (P < 0.001) and test group (P = 0.016). More exciting, our model showed good prognosis prediction in both stage I-II (P = 0.020) and stage III-IV (P = 0.001). The nomogram model could further improve the accuracy of prognosis prediction. Interestingly, glucose-related metabolic pathways, which were closely related to cuproptosis, were enriched in the low-risk group. Meanwhile, the immune infiltration scores were lower in the high-risk group. The high-risk group was more sensitive to OSI.906 and ABT.888, while low-risk group was more sensitive to Sorafenib. Three lncRNAs, FALEC, AC083967.1 and AC010997.4, were highly expressed in serum of COAD patients, and the AUC was 0.772, 0.726 and 0.714, respectively, indicating their valuable diagnostic value. CONCLUSIONS Our research constructed a prognostic signature based on 7 CRLs and found three promising diagnostic markers for COAD patients. Our results provided a reference to the personalized immunotherapy strategies.

Abstract
Deregulation of long non-coding RNAs (lncRNAs) has been implicated in tumorigenesis. FALEC is a lncRNA upregulated in multiple cancer types. FALEC functions as an oncogene through various mechanisms, such as competitively binding miRNAs and regulation of PI3K/AKT, Tp53 and phosphatase and tensin homolog signaling pathways. Pertinent to clinical practice, the use of FALEC as a putative biomarker has been identified. These findings suggested that FALEC might play a pivotal role in human cancers. Further studies are warranted to examine the diagnostic and prognostic performance of FALEC as a noninvasive biomarker in liquid biopsy samples and promote its development to be a clinically utilizable prognostic cancer biomarker and molecular therapeutic target.

Abstract
Long non-coding RNAs (lncRNAs) and microRNAs (miRs) have critical roles in the progression of various diseases. The present study aimed to investigate the levels and clinical significance of lncRNA taurine upregulated gene 1 (TUG1) and miR-145-5p in patients with chronic heart failure (CHF) and explore their indicative value regarding disease severity. TUG1 and miR-145-5p levels were detected by reverse-transcription quantitative PCR. Correlations were examined using Pearson's correlation analysis. Receiver operating characteristic analysis was used to evaluate the diagnostic value of TUG1, miR-145-5p and brain natriuretic peptide (BNP). Survival analysis was performed by the Kaplan-Meier method. Cox regression analysis was used to evaluate the prognostic value of TUG1 and miR-145-5p. The levels of interleukin-6 and tumor necrosis factor-α in serum were detected by ELISA. The results indicated that TUG1 was upregulated and miR-145-5p was downregulated in patients with CHF and they were negatively correlated. TUG1 and miR-145-5p were associated with the left ventricle ejection fraction and were able to indicate the severity of CHF. Serum TUG1 and miR-145-5p had a certain diagnostic value and the combination of BNP, TUG1 and miR-145-5p had high diagnostic accuracy. TUG1 and miR-145-5p were closely associated with overall survival and may function as independent prognostic biomarkers for patients with CHF. In addition, TUG1 and miR-145-5p levels were markedly correlated with inflammation in CHF. Upregulated TUG1 and downregulated miR-145-5p may indicate the severity of CHF, may serve as diagnostic and prognostic biomarkers and may be involved in CHF progression by regulating inflammatory responses.

Abstract
Circulating cell-free nucleic acids recently became attractive targets to develop non-invasive diagnostic tools for cancer detection. Along with DNA and mRNAs, transcripts lacking coding potential (non-coding RNAs, ncRNAs) directly involved in the process of tumor pathogenesis have been recently detected in liquid biopsies. Interestingly, circulating ncRNAs exhibit specific expression patterns associated with cancer and suggest their role as novel biomarkers. However, the potential of circulating long ncRNAs (c-lncRNAs) to be markers in osteosarcoma (OS) is still elusive. In this study we performed a systematic review to identify thirteen c-lncRNAs whose altered expression in blood associate with OS. We herein discuss the potential impact that these c-lncRNAs may have on clinical decision-making in the management of OS. Overall, we aimed to provide novel insights that can contribute to the development of future precision medicine in oncology.

Abstract
The functions of a large number of non-coding genes in human DNA have yet to be accurately identified. Long non-coding RNA (lncRNA) measuring 10 kb or less in length regulates transcription or post-transcriptional events. The lncRNAs have attracted increased attention of researchers in recent years. In this review, we summarize the recently published lncRNAs which are known to influence cancer development and progression. We also discuss recent studies investigating tumor-specific lncRNA expression. These lncRNAs provide very useful information that allows prediction of the degree of malignancy and a survival rate in cancer patients as clinically relevant biomarkers. Because symptoms and progression of cancer differ from onset to death between males and females, it is important to consider the gender of the patient when diagnosing cancer and predicting the progression. Considering the importance of gender difference, we also examine the influence of sex hormones involved in the expression and regulation of lncRNAs as biomarkers. Many of the lncRNAs examined in this review have been studied in cancers occurring in the female or male reproductive organs, but the association between lncRNAs and sex hormones has also been reported in common organs such as the lung, renal and colon. Although lncRNAs have not yet been widely used as definitive cancer indicators, recent studies have demonstrated the potential role of lncRNAs as biomarkers and therapeutic targets reflecting sex-specificity in a number of different cancers.

Abstract
Chronic heart failure (CHF) is the leading cause of death worldwide. The regulatory interactions of long non-coding RNA (lncRNAs) and microRNAs (miRs) have important roles in multiple diseases. However, the clinical significance of the nuclear-enriched abundant transcript 1 (NEAT1)/miR-129-5p axis in CHF has remained elusive. The present study explored whether the NEAT1/miR-129-5p axis may be a suitable diagnostic and prognostic marker for CHF. The expression of lncRNA NEAT1 and miR-129-5p in the serum of patients with CHF was analyzed by reverse transcription-quantitative PCR. Furthermore, inter-indicator correlations were assessed by Pearson correlation coefficient analysis. Receiver operating characteristic (ROC) curves were generated to evaluate the ability of NEAT1, miR-129-5p and brain natriuretic peptide (BNP) to identify patients with CHF. The prognostic value of the NEAT1/miR-129-5p axis was analyzed by drawing Kaplan-Meier survival curves and by Cox logistic regression analysis. Baseline data were not significantly different between CHF (n=70) and control subjects (n=62). The serum level of NEAT1 was increased and the expression level of miR-129-5p was decreased in patients with CHF (all P<0.001). The ROC curves suggested that serum NEAT1 and miR-129-5p were of diagnostic value in patients with CHF and the combined diagnostic accuracy of NEAT1, miR-129-5p and BNP was significantly improved. Kaplan-Meier and multivariate Cox regression analysis suggested that low NEAT1 and high miR-129-5p were able to predict overall survival of patients with CHF (all P<0.01). In conclusion, the present study indicated that patients with CHF had increased NEAT1 and decreased miR-129-5p expression. The deregulated NEAT1/miR-129-5p axis may provide novel non-invasive biomarkers for the diagnosis and prognosis of CHF.

Abstract
BACKGROUND Colorectal cancer (CRC) is one of the most common digestive malignant tumors globally. Focally amplified lncRNA on chromosome 1 (FALEC) is a novel lncRNA that has been reported to be involved in many biological processes during carcinogenesis. However, its role in CRC remains poorly understood. METHODS Gene expression at mRNA or protein level was measured by qRT-PCR or western blot, respectively. In vitro experiments including EdU, colony formation, flow cytometry, wound-healing and transwell assays, as well as in vivo xenograft experiment, were utilized to determine the functional role of FALEC in CRC. Relevant mechanical assays were performed to investigate the underlying molecular mechanism. RESULTS FALEC was aberrantly up-regulated in CRC. FALEC knockdown could impair CRC cell proliferation, migration and invasion, whereas facilitate cell apoptosis. MiR-2116-3p was revealed to be sponged by FALEC. PIWIL1 was identified as the target of miR-2116-3p. Mechanically, FALEC restored the expression of PIWIL1 via absorbing miR-2116-3p. MiR-2116-3p inhibition and PIWIL1 enrichment could counteract the anti-tumor impact induced by silenced FALEC on the oncogenic behaviors of CRC cells. CONCLUSION Our study revealed that FALEC promoted CRC progression via restoring the expression of miR-2116-3p-targeted PIWIL1, suggesting the potential application of targeting FALEC in the treatment of CRC.

Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) remains the most common cause of human cancer-related death worldwide, and the present study aims to explore the roles of long non-coding (lnc)RNA ZEB2-AS1 in NSCLC and the related mechanism. METHODS Quantitative real-time-polymerase chain reaction was performed to compare the expressions of ZEB2-AS1 in NSCLC cancer tissue and the adjacent non-tumorous tissues. The diagnostic and prognostic roles of ZEB2-AS1 in NSCLC were also evaluated by the receiver operating characteristic curve and the Kaplan-Meier survival analysis. NSCLC cell line A549 cells were transfected with ZEB2-AS1 siRNA, and the cell viability, migration, invasion, and epithelial-mesenchymal transition (EMT) of the ZEB2-AS1 siRNA group and control group were compared. RESULTS ZEB2-AS1 was significantly increased in NSCLC tissues. The knockdown of ZEB2-AS1 markedly inhibited the cell viability, migration, invasion, and EMT of A549 cells in vitro. CONCLUSION ZEB2-AS1 was up-regulated in NSCLC, and it may serve as a potential target for the diagnosis, prognosis, and treatment of NSCLC.

Abstract
Accumulating evidence has supported the concept that long noncoding RNAs (lncRNAs) participate in the initiation and progression of human cervical cancer (CC). The long intergenic nonprotein-coding RNA 173 (LINC00173) is a recently identified cancer-associated factor. However, the expression and biological role of LINC00173 in CC are poorly understood. Here, for the first time, we found that the expression of LINC00173 was decreased in CC tissues compared with that in nontumor tissues. Data from The Cancer Genome Atlas (TCGA) further revealed that the downregulated expression of LINC00173 in CC tissues was correlated with poor survival. Functionally, LINC00173 overexpression suppressed HeLa cell proliferation via induction of G0/G1 phase arrest. Ectopic expression of LINC00173 also repressed the invasiveness of HeLa cells. Conversely, LINC00173 depletion resulted in the enhanced proliferation and invasiveness of C33A cells. Mechanistically, LINC00173 functioned as a molecular sponge for miR-182-5p and inversely regulated the miR-182-5p level in CC cells. F-box and WD repeat domain-containing 7 (FBXW7) was identified as the target of miR-182-5p. LINC00173 overexpression enhanced the FBXW7 level via regulation of miR-182-5p in HeLa Cells. More importantly, the inhibitory effects of LINC00173 on HeLa cell proliferation and invasiveness were reversed by FBXW7 silencing. Taken together, the results indicate that the LINC00173/miR-182-5p/FBXW7 axis is critical for CC progression, which might offer new insights into effective therapy for CC.

Abstract
Cervical cancer (CC) is a malignant tumor that could seriously endanger women's life and health, of which cervical squamous cell carcinoma (CESC) accounts for more than 80%. High-risk human papillomavirus (HR-HPV) infection is the primary cause of CC. The 5-year survival rate is low due to poor prognosis. We need to explore the pathogenesis of CC and seek effective biomarkers to improve prognosis. The purpose of this research is to construct an HR-HPV-related long non-coding RNA (lncRNA) signature for predicting the survival and finding the biomarkers related to CC prognosis. First, we downloaded the CESC data from The Cancer Genome Atlas (TCGA) database to find HR-HPV-related lncRNAs in CC. Then, the differentially expressed lncRNAs were analyzed by univariate and multivariate Cox regression. Six lncRNAs were found to be associated with the prognosis and can be used as independent prognostic factors. Next, based on these prognostic genes, we established a risk score model, which showed that patients with higher score had poorer prognosis and higher mortality. Moreover, the Kaplan-Meier curve of the model indicated that the model was statistically significant (p < 0.05). The survival-receiver operating characteristic curve showed that the model could also predict the survival of CC patients (the area under the curve, AUC = 0.65). More importantly, nomogram was drawn with clinical features and risk score, which verified the above conclusion, and its calibration curve and c-index index fully demonstrated that the prediction model could predict the progress of CC. We also validated the risk score model in head and neck cancer, and the results indicated that the model had obvious prognostic ability. Finally, we analyzed the correlation between clinical features and survival, and found that neoplasm cancer (p < 0.000) and risk score (p < 0.000) were independent prognostic factors for CC. In conclusion, the study established HR-HPV-related lncRNA signature, which provided a reliable prognostic tool, and was of great significance for finding the biomarkers related to HR-HPV infection in CC.

Abstract
Long noncoding RNAs (lncRNAs) are characterized as a group of endogenous RNAs that are more than 200 nucleotides in length and have no protein-encoding function. More and more evidence indicates that lncRNAs play vital roles in various human diseases, especially in tumorigenesis. Focally amplified lncRNA on chromosome 1 (FAL1), a novel lncRNA with enhancer-like activity, has been identified as an oncogene in multiple cancers and high expression level of FAL1 is usually associated with poor prognosis. Dysregulation of FAL1 has been shown to promote the proliferation and metastasis of cancer cells. In the present review, we summarized and illustrated the functions and underlying molecular mechanisms of FAL1 in the occurrence and development of different cancers and other diseases. FAL1 has the potential to appear as a feasible diagnostic and prognostic tool and new therapeutic target for cancer patients though further investigation is needed so as to accelerate clinical application.

[PMID: 31416190 PMCID: PMC6721601 DOI: 10.3390/cancers11081170] [Citation(s) in RCA: 116] [Impact Index Per Article: 23.2] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2019] [Revised: 08/04/2019] [Accepted: 08/10/2019] [Indexed: 02/06/2023] Open
Abstract
The last two decades of cancer research have been devoted in two directions: (1) understanding the mechanism of carcinogenesis for an effective treatment, and (2) improving cancer prevention and screening for early detection of the disease. This last aspect has been developed, especially for certain types of cancers, thanks also to the introduction of new concepts such as liquid biopsies and precision medicine. In this context, there is a growing interest in the application of alternative and noninvasive methodologies to search for cancer biomarkers. The new frontiers of the research lead to a search for RNA molecules circulating in body fluids. Searching for biomarkers in extracellular body fluids represents a better option for patients because they are easier to access, less painful, and potentially more economical. Moreover, the possibility for these types of samples to be taken repeatedly, allows a better monitoring of the disease progression or treatment efficacy for a better intervention and dynamic treatment of the patient, which is the fundamental basis of personalized medicine. RNA molecules, freely circulating in body fluids or packed in microvesicles, have all the characteristics of the ideal biomarkers owing to their high stability under storage and handling conditions and being able to be sampled several times for monitoring. Moreover, as demonstrated for many cancers, their plasma/serum levels mirror those in the primary tumor. There are a large variety of RNA species noncoding for proteins that could be used as cancer biomarkers in liquid biopsies. Among them, the most studied are microRNAs, but recently the attention of the researcher has been also directed towards Piwi-interacting RNAs, circular RNAs, and other small noncoding RNAs. Another class of RNA species, the long noncoding RNAs, is larger than microRNAs and represents a very versatile and promising group of molecules which, apart from their use as biomarkers, have also a possible therapeutic role. In this review, we will give an overview of the most common noncoding RNA species detectable in extracellular fluids and will provide an update concerning the situation of the research on these molecules as cancer biomarkers.
