- Increasing evidence has demonstrated that enhanced PHF20 expression plays a crucial role in cancer development and progression. However, little is known about the prognostic value of PHF20 expression in breast cancer (BRCA). In this study, we attempted to explore the expression pattern of PHF20 and its associations with prognosis and immune status in BRCA. The gene expression data and clinical information of 1109 BRCA samples were downloaded from TCGA database. The expression level of PHF20 protein was determined using UALCAN and HPA database. Kaplan-Meier method and CIBERSORT algorithm were used to analyze the associations of PHF20 expression with overall survival (OS) and immune microenvironment, respectively. Besides, GSEA analysis was conducted to explore potential biological functions and molecular mechanisms of PHF20 in BRCA. Moreover, starBase database was applied to construct a ceRNA nework. PHF20 was highly expressed in BRCA samples both at the transcriptional and protein level, and was strongly correlated with the OS and immune status. Univariable and multivariate Cox regression analyses identified PHF20 as an independent prognostic factor. Additionally, GSEA analysis showed that high PHF20 expression was closely associated with TGF-β signaling pathway, Wnt signaling pathway, and adherens junction. Furthermore, three ceRNA networks (AC037198.1/hsa-miR-223-3p/PHF20, CBR3-AS1/hsa-miR-223-3p/PHF20, and ZNF561-AS1/hsa-miR-223-3p/PHF20) were identified by starBase analysis. Functional experiments validated that PHF20 knockdown inhibited the cell viability and progression in BRCA cells. PHF20 overexpression was significantly associated with poor prognosis and immune status in BRCA, and could act as a potential novel prognostic biomarker for BRCA. - Source: PubMed

Chen ZhiyuanZhong ShanliangZhang ZhengdongTang Jinhai - Hepatocellular carcinoma is a common malignant tumor with high recurrence rate. Long non-coding RNA (lncRNA) ZNF561 antisense RNA 1 (ZNF561-AS1) functions as an oncogenic lncRNA to promote the tumorigenesis of colorectal cancer. The role of ZNF561-AS1 in hepatocellular carcinoma remains unknown. ZNF561-AS1 was elevated in hepatocellular carcinoma tissues and cells. Silence of ZNF561-AS1 reduced cell viability and inhibited the proliferation of hepatocellular carcinoma. The angiogenesis of hepatocellular carcinoma was also suppressed by loss of ZNF561-AS1 with a decrease of angiopoietin 2, fibroblast growth factor 1, and vascular endothelial growth factor. ZNF561-AS1 bind to miR-302a-3p, and decreased expression of miR-302a-3p in hepatocellular carcinoma. Moreover, miR-302a-3p reduced platelet-derived growth factor-D (PDGFD) in hepatocellular carcinoma, and inhibition of miR-302a-3p attenuated ZNF561-AS1 silence-induced decrease of PDGFD. In conclusion, silence of ZNF561-AS1 might inhibit cell proliferation and angiogenesis of hepatocellular carcinoma through downregulation of miR-302a-3p-mediated PDGFD. - Source: PubMed
Zheng JihuGuo ZijianWen ZhanchaoChen Huikang - Long non-coding RNAs (lncRNAs) have been widely recognized as important regulators in myocardial infarction (MI) and other heart diseases. Our study aimed to investigate the mechanism and biological function of an unknown lncRNA zinc finger protein 561 antisense RNA 1 (ZNF561-AS1) in MI. After confirming the MI model was successful, we applied reverse transcription quantitative polymerase chain reaction and Western blot (WB) and found that the expression of NLR family pyrin domain containing 3 (NLRP3), interleukin (IL)-1β, and IL-18 was substantially increased in infarct and border zones of MI mice heart at 24 h and 72 h compared with that in sham-operated models. Moreover, we found that NLRP3 expression was promoted in hypoxia human cardiomyocytes (HCMs). Through cell function assays including CCK-8, 5-Ethynyl-2'-deoxyuridine (EdU), flow cytometry, and TdT-mediated dUTP Nick-End Labeling (TUNEL), supported by WB analysis, we verified that silencing of NLRP3 facilitated proliferation but impeded apoptosis of hypoxia-induced myocardial cell. Moreover, Ago2-RIP and RNA pull-down assays displayed that NLRP3 could combine with miR-223-3p. Luciferase reporter assays further confirmed that NLRP3 was directly targeted by miR-223-3p. Simultaneously, we found that miR-223-3p was the downstream gene of ZNF561-AS1. In addition, we conducted a series of rescue experiments to affirm that ZNF561-AS1 regulated cell proliferation and apoptosis in MI through miR-223-3p/NLRP3 axis. - Source: PubMed

Si ZizhenYu LeiJing HaoyuWu LunWang Xidi - Accumulating evidence indicates that lncRNAs can interact with miRNAs to regulate target mRNAs through competitive interactions. However, this mechanism remains largely unexplored in laryngeal squamous cell carcinoma (LSCC). In this study, transcriptome-wide RNA sequencing was performed on 3 pairs of LSCC tissues and adjacent normal tissues to investigate the expression profiles of lncRNAs, miRNAs and mRNAs, with differential expression of 171 lncRNAs, 36 miRNAs and 1709 mRNAs detected. Seven lncRNAs, eight mRNAs and three miRNAs were identified to be dysregulated in patients' tissues by using qRT-PCR. GO and KEGG pathway enrichment analyses were performed to elucidate the potential functions of these differentially expressed genes in LSCC. Subsequently, a ceRNA (lncRNA-miRNA-mRNA) network including 4631 ceRNA pairs was constructed based on predicted miRNAs shared by lncRNAs and mRNAs. Cis- and transregulatory lncRNAs were analysed by bioinformatics-based methods. Importantly, mRNA-related ceRNA networks (mRCNs) were further obtained based on potential cancer-related coding genes. Coexpression between lncRNAs and downstream mRNAs was used as a criterion for the validation of mRCNs, with the ZNF561-AS1-miR217-WNT5A and SATB1-AS1-miR1299-SAV1/CCNG2/SH3 KBP1/JADE1/HIPK2 ceRNA regulatory interactions determined, followed by experimental validation after siRNA transfection. Moreover, ceRNA activity analysis revealed that different activities of ceRNA modules existing in specific pathological environments may contribute to the tumorigenesis of LSCC. Consistently, both downregulated SATB1-AS1 and ZNF561-AS1 significantly promoted laryngeal cancer cell migration and invasion, indicating their important roles in LSCC via a ceRNA regulatory mechanism. Taken together, the results of this investigation uncovered and systemically characterized a lncRNA-related ceRNA regulatory network that may be valuable for the diagnosis and treatment of LSCC. - Source: PubMed
