LncRNAs serve as crucial regulators in the survival and proliferation of tumors. This study is dedicated to exploring functional significance lncRNA PGM5-AS1 breast cancer (BRCA). First, expression level BRCA patients its diagnostic ability for were analyzed by RT-qPCR Receiver Operating Characteristic curve. Subsequently, LnCAR database was used preliminarily explore relationship between prognosis. Moreover, we investigated effects on proliferation, apoptosis, migration cells MTT assay, flow cytometry, Transwell assay. More importantly, regulation effect downstream target miR-182-5p verified dual luciferase reporting experiment, role further explored vitro experiments. significantly decreased both cell lines. In diagnosis BRCA, sensitivity specificity 81.5% 78.5%. Furthermore, lower levels are associated with a poor prognosis affected patients. studies demonstrate that upregulation confers protective against markedly inhibiting viability migratory capacity tumor cells. overexpression inhibited high fact, inhibition detrimental vitro. has potential marker acts an inhibitor BRCA. It inhibits metastasis targeting miR-182-5p.

Lung cancer is the most common malignancy, being a serious threat of human lives. The incidence and mortality lung has been increasing rapidly in past decades. Although development new therapeutic modes, such as target therapy, overall survival rate remains low. It urgent to advance understanding molecular oncology find novel biomarkers targets for early diagnosis, treatment, prognostic prediction cancer. Long non-coding RNAs (lncRNAs) are non-protein coding RNA transcripts that more than 200 nucleotides length. LncRNAs exert diverse biological functions by regulating gene expressions at transcriptional, translational, post-translational levels. In decade, it shown lncRNAs extensively involved pathogenesis various diseases, including this review, we highlighted characterized discussed their translational potential clinics.

Identification and Validation of a Three Pyroptosis-Related lncRNA Signature for Prognosis Prediction in Lung Adenocarcinoma

Frontiers in Genetics, Год журнала: 2022, Номер 13

Pyroptosis, defined as programmed cell death, results in the release of inflammatory mediators. Recent studies have revealed that pyroptosis plays essential roles antitumor immunity and immunotherapy efficacy. Long noncoding RNAs (lncRNAs) are involved a variety biological behaviors tumor cells, although mechanisms lncRNAs rarely studied. Our study aimed to establish novel pyroptosis-related lncRNA signature forecasting tool for predicting prognosis ascertaining immune value. Based on lung adenocarcinoma (LUAD) patients from The Cancer Genome Atlas (TCGA), we performed Pearson's correlation analysis identify lncRNAs. After differentially expressed gene univariate Cox regression analysis, selected prognosis-related Finally, multivariate three signature. Kaplan-Meier (KM) survival analyses receiver operating characteristic (ROC) curves indicated excellent performance LUAD patients. At same time, applied multidimensional approaches further explore functional enrichment, microenvironment (TME) landscape, efficacy among different risk groups. A nomogram was constructed by integrating scores clinical characteristics, which validated using calibrations ROC curves. Three lncRNAs, namely, AC090559.1, AC034102.8, AC026355.2, were this used classify into low- high-risk Overall time (OS) higher low-risk group than group, also our cohort Shandong Provincial Hospital. TME landscape abundance infiltrating cells greater prevalence immune-related events existed group. Meanwhile, expression checkpoint (ICP) genes, immunophenoscore (IPSs), T dysfunction demonstrated better response Combined with predictions Tumor Immune Dysfunction Exclusion (TIDE) website, found significantly benefited death 1 (PD-1) cytotoxic T-lymphocyte-associated protein 4 (CTLA4) blockade (ICB) therapy compared those Furthermore, drug susceptibility identified potential sensitive chemotherapeutic drugs each In study, constructed, could accurately predict

Function of the Long Noncoding RNAs in Hepatocellular Carcinoma: Classification, Molecular Mechanisms, and Significant Therapeutic Potentials

Bioengineering, Год журнала: 2022, Номер 9(8), С. 406 - 406

Опубликована: Авг. 21, 2022

Hepatocellular carcinoma (HCC) is the most common and serious type of primary liver cancer. HCC patients have a high death rate poor prognosis due to lack clear signs inadequate treatment interventions. However, molecular pathways that underpin pathogenesis remain unclear. Long non-coding RNAs (lncRNAs), new RNAs, been found play important roles in HCC. LncRNAs ability influence gene expression protein activity. Dysregulation lncRNAs has linked growing number disorders, including As result, improved understanding could lead insights into etiology, as well approaches for early detection The latest results with respect role controlling multiple were summarized this study. processes by which advancement interacting chromatin, proteins at epigenetic, transcriptional, post-transcriptional levels examined. This critical review also highlights recent breakthroughs lncRNA signaling progression, shedding light on potential applications diagnosis therapy.
