Abstract
Increasing evidence shows that microRNAs (miRNAs) contribute vital roles in papillary thyroid carcinoma (PTC) carcinogenesis, proliferation, invasion, and so on. As the most common endocrine malignancy, there still have largely unknown molecular events. First, our analysis and open access database information indicates that the downregulation of let-7a-5p accelerates PTC progression. Next, lentivirus mediates the overexpression of let-7a-5p PTC cells, and found let-7a-5p suppressed cancer cells proliferation and invasion. Interestingly, bioinformatics analysis hints NR6A1 is the potential target gene of let-7a-5p. The regulation was validated by luciferase and quantitative reverse transcription polymerase chain reaction (qRT-PCR) in PTC tissue and the clinic tumors. Moreover, let-7a-5p regulated NR6A1 involved in PTC cells lipogensis in vitro and in vivo. Finally, let-7a-5p abrogates PCT xenograft tumors growth, NR6A1 expression and lipogenesis. Taken together, our data indicates that let-7a-5p suppresses PCT progression through decreased lipogenesis, the related let-7a-5p/NR6A1axis might be promising candidate targets for PTC treatment.

Abstract
Metastasis is a major cause of treatment failure and poor outcomes in cancer patients. The data used in the current study was downloaded from TCGA and GEO databases. Differentially expressed metastasis-related genes were identified and the biological functions were implemented. Kaplan-Meier analysis univariate, and, multivariate Cox regression analyses were performed to identify robust prognostic biomarkers, followed by construction of the risk model and nomogram. Gene set enrichment analysis was performed to identify pathways enriched in low- and high-risk groups. POLR2J3 and MYH11 were treated as prognostic biomarkers in LSCC and the risk model was constructed. Receiver operating characteristic curves revealed the good performance of the risk model. A nomogram with high accuracy was constructed, as evidenced by calibration and decision curves. Moreover, we found that the expressions of POLR2J3 and MYH11 was significantly higher in metastasis tissues compared with those in non-metastasis tissues by RT-qPCR and IHC. Our study identified novel metastasis-related prognostic biomarkers in LSCC and constructed a unique nomogram for predicting the prognosis of LSCC patients. Moreover, we explored the related mechanisms of metastasis-related genes in regulating LSCC.

Pharmacol Res 2023; 190:106732. [PMID: 36931542 DOI: 10.1016/j.phrs.2023.106732] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/25/2022] [Revised: 03/13/2023] [Accepted: 03/14/2023] [Indexed: 03/17/2023]
Abstract
High mobility group A 2 (HMGA2) is a protein that modulates the structure of chromatin in the nucleus. Importantly, aberrant expression of HMGA2 occurs during carcinogenesis, and this protein is an upstream mediator of cancer hallmarks including evasion of apoptosis, proliferation, invasion, metastasis, and therapy resistance. HMGA2 targets critical signaling pathways such as Wnt/β-catenin and mTOR in cancer cells. Therefore, suppression of HMGA2 function notably decreases cancer progression and improves outcome in patients. As HMGA2 is mainly oncogenic, targeting expression by non-coding RNAs (ncRNAs) is crucial to take into consideration since it affects HMGA2 function. MicroRNAs (miRNAs) belong to ncRNAs and are master regulators of vital cell processes, which affect all aspects of cancer hallmarks. Long ncRNAs (lncRNAs) and circular RNAs (circRNAs), other members of ncRNAs, are upstream mediators of miRNAs. The current review intends to discuss the importance of the miRNA/HMGA2 axis in modulation of various types of cancer, and mentions lncRNAs and circRNAs, which regulate this axis as upstream mediators. Finally, we discuss the effect of miRNAs and HMGA2 interactions on the response of cancer cells to therapy. Regarding the critical role of HMGA2 in regulation of critical signaling pathways in cancer cells, and considering the confirmed interaction between HMGA2 and one of the master regulators of cancer, miRNAs, targeting miRNA/HMGA2 axis in cancer therapy is promising and this could be the subject of future clinical trial experiments.

Chen F, Lao Z, Zhang H, Wang J, Wang S. Knockdown of circ_0001883 may inhibit epithelial-mesenchymal transition in laryngeal squamous cell carcinoma via the miR-125-5p/PI3K/AKT axis. Exp Ther Med 2021; 22:1007. [PMID: 34345289 PMCID: PMC8311254 DOI: 10.3892/etm.2021.10440] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 06/09/2021] [Indexed: 12/27/2022] Open
Abstract
Laryngeal squamous cell carcinoma (LSCC) is a malignant tumor with increasing incidence and poor prognosis. Circular RNAs (circRNAs) are known to modulate tumorigenesis and cancer development that may function through microRNAs (miRs). The aim of the present study was to investigate the functional roles of circ_0001883 in LSCC and the underlying molecular mechanism. The expression of circ_0001883 was upregulated and measured using reverse transcription-quantitative PCR (RT-qPCR) and RNase R. miR-125b-5p expression was downregulated in LSCC tissues and cells as determined using RT-qPCR. Subsequently, knockdown of circ_0001883 inhibited LSCC cell migration, invasion and epithelial-mesenchymal transition (EMT), which were tested by wound healing assays, Transwell assays and western blotting, respectively. Bioinformatics analysis predicted that circ_0001883 was a sponge of miR-125b-5p, which was verified using a dual-luciferase reporter assay. Knockdown of circ_0001883 played a functional role by sponging miR-125b-5p. Additionally, circ_0001883 and miR-125b-5p influenced phosphorylation of PI3K and AKT, detected via western blotting. In an in vivo study, knockdown of circ_0001883 reduced tumor volume and weight in mice, along with enhanced miR-125b-5p and E-cadherin expression levels, and decreased N-cadherin, phosphorylated (p)-PI3K/PI3K and p-AKT/AKT ratios. In conclusion, knockdown of circ_0001883 inhibited cell migration, invasion and EMT of LSCC by sponging miR-125b-5p. This is hypothesized to be via the PI3K/AKT signaling pathway, which suggested that circ_0001883 has potential for LSCC therapy.
