Huang JN, Zhang HM, Cai JD, Wang WL, Wang P. Long noncoding RNA DSCR8 promotes the proliferation of liver cancer cells and inhibits apoptosis via the miR-22-3p/ARPC5 Axis. J Cancer 2023; 14:35-49. [PMID: 36605483 PMCID: PMC9809336 DOI: 10.7150/jca.79475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Accepted: 11/07/2022] [Indexed: 01/04/2023] Open
Abstract
Emerging evidence shows that long noncoding RNAs (lncRNAs) play a vital role in the tumorigenesis and development of cancer, implying that some lncRNAs could be potential therapeutic targets. In this study, we employed Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases to construct a ceRNA network by bioinformatic analysis, and the Down syndrome critical region 8 (lncRNA_DSCR8)/miR-22-3p/actin-related protein 2/3 complex subunit 5 (ARPC5) axis was identified as a potential target in liver cancer (LC). Next, we found that DSCR8 is highly expressed in LC cell lines Hep3B and Huh7. In addition, sh-DSCR8 inhibits cell proliferation and promotes cell apoptosis. Furthermore, we certified that DSCR8 serves as function as a sponge for miR-22-3p, while ARPC5 is a target gene of miR-22-3p, and the functions of DSCR8 promoting LC cell proliferation could be rescued by miR-22-3p. This study suggests that lncRNA_DSCR8 promotes LC progression and inhibits its apoptosis by regulating the miR-22-3p/ARPC5 axis, signifying that DSCR8 could be a novel therapeutic target for LC.

Wu Q, Wang L, Tsui SKW. Mutational signatures representative transcriptomic perturbations in hepatocellular carcinoma. Front Genet 2022; 13:970907. [PMID: 36081995 PMCID: PMC9445436 DOI: 10.3389/fgene.2022.970907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Accepted: 07/27/2022] [Indexed: 11/17/2022] Open
Abstract
Hepatocellular carcinoma (HCC) is a primary malignancy with increasing incidence and poor prognosis. Heterogeneity originating from genomic instability is one of the critical reasons of poor outcomes. However, the studies of underlying mechanisms and pathways affected by mutations are still not intelligible. Currently, integrative molecular-level studies using multiomics approaches enable comprehensive analysis for cancers, which is pivotal for personalized therapy and mortality reduction. In this study, genomic and transcriptomic data of HCC are obtained from The Cancer Genome Atlas (TCGA) to investigate the affected coding and non-coding RNAs, as well as their regulatory network due to certain mutational signatures of HCC. Different types of RNAs have their specific enriched biological functions in mutational signature-specific HCCs, upregulated coding RNAs are predominantly associated with lipid metabolism-related pathways, and downregulated coding RNAs are enriched in axonogenesis for tumor microenvironment generation. Additionally, differentially expressed miRNAs are inclined to concentrate in cancer-related signaling pathways. Some of these RNAs also serve as prognostic factors that help predict the survival outcome of HCCs with certain mutational signatures. Furthermore, deregulation of competing endogenous RNA (ceRNA) regulatory network is identified, which suggests a potential therapy via interference of miRNA activity for mutational signature-specific HCC. This study proposes a projection approach to reduce therapeutic complexity from genomic mutations to transcriptomic alterations. Through this method, we identify genes and pathways critical for mutational signature-specific HCC and further discover a series of prognostic markers indicating patient survival outcome.

CTHRC1 expression is a novel shared diagnostic and prognostic biomarker of survival in six different human cancer subtypes. Sci Rep 2021; 11:19873. [PMID: 34615943 PMCID: PMC8494806 DOI: 10.1038/s41598-021-99321-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 09/14/2021] [Indexed: 02/08/2023] Open
Abstract
According to the previous reports, the collagen triple helix repeat containing 1 (CTHRC1) causes tumorigenesis by modulating the tumor microenvironment, however, the evidence is limited to a few human cancer subtypes. In the current study, we analyzed and validated the CTHRC1 expression variations in 24 different human cancer tissues paired with normal tissues using publically available databases. We observed that CTHRC1 was overexpressed in all the 24 major subtypes of human cancers and its overexpression was significantly associated with the reduced overall survival (OS) duration of head and neck squamous cell carcinoma (HNSC), kidney renal clear cell carcinoma (KIRC), liver hepatocellular carcinoma (LIHC), Lung adenocarcinoma (LUAD), stomach adenocarcinoma (STAD), and Uterine corpus endometrial carcinoma (UCEC). This implies that CTHRC1 plays a significant role in the development and progression of these cancers. We further noticed that CTHRC1 was also overexpressed in HNSC, KIRC, LIHC, LUAD, STAD, and UCEC patients of different clinicopathological features. Pathways enrichment analysis revealed the involvement of CTHRC1 associated genes in seven diverse pathways. We also explored few interesting correlations between CTHRC1 expression and promoter methylation, genetic alterations, CNVs, CD8+ T immune cells infiltration, and tumor purity. In conclusion, CTHRC1 can serve as a shared diagnostic and prognostic biomarker in HNSC, KIRC, LIHC, LUAD, STAD, and UCEC patients of different clinicopathological features.
