Tissue expression of miR-449a as risk factor for occult neck metastasis in patients with cT3-T4 N0 laryngeal cancer. A pilot study. Eur Arch Otorhinolaryngol 2024:10.1007/s00405-024-08743-5. [PMID: 38771342 DOI: 10.1007/s00405-024-08743-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 05/16/2024] [Indexed: 05/22/2024]
Abstract
OBJECTIVE To explore the potential role of miR-449a as biomarker for laryngeal squamous cell carcinoma (LSCC), especially in the decision strategy of neck dissection (ND). METHODS Each patient underwent total laryngectomy and bilateral ND (levels II-IV); during surgery, tissue samples of around 1 × 0.5 cm were extracted from both healthy tissue adjacent to the tumor and the visibly affected tumor tissue. The extraction of total RNA, encompassing miRNA, was performed using a mirVana PARIS kit. To detect miR449a, cDNA was synthesized from 200 ng of RNA using a TaqMan miRNA reverse transcription kit. RESULTS The study group was formed of 66 patients (62 males, and 4 females) with LSCC, aged between 39 and 77 years (mean 60 + 14.56 yr). MiR-449a was up-regulated in twenty-eight tumors (42%), while it was down-regulated in 38 samples (58%). In the present study, there was a statistical relevance for miR-449a tissue expression for pN staging (p = 0.017), and PNI (p = 0.005). Eight tumors (12%) cN0 became pN + showing occult cervical lymph node metastases at the final histopathological examination, and all of these patients showed miR-449a downregulation. CONCLUSION Super-selective ND (sparing the sub evels IIb and IV) might be the approach to cT3-T4 N0 LSCCs with upregulation of miR-449a; on the other hand, to ensure and effective control of occult neck metastases it would be appropriate to reserve elective ND (including sublevels IIb and IV) for cT3-T4 N0 LSCCs with miR-449a downregulation. Although promising, due to the small size of the cohort, the results of this work can be considered preliminary and need to be confirmed by prospective and larger studies.

The Biomarker Like the Correlation between Vasculogenic Mimicry, Vascular Endothelial Cadherin, Sex-DeterminingRegion on Y-Box Transcription Factor 17, and Cyclin D1 in Oesophageal Squamous Cell Carcinoma. JOURNAL OF ONCOLOGY 2022; 2022:8915503. [PMID: 36072972 PMCID: PMC9444392 DOI: 10.1155/2022/8915503] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Accepted: 07/22/2022] [Indexed: 12/24/2022]
Abstract
Background This study aimed to explore the relationships between the sex-determining region on Y (SRY) box transcription factor 17 (SOX17), Cyclin D1, vascular endothelial cadherin (VE-cadherin), and vasculogenic mimicry (VM) in the occurrence and development of esophageal squamous cell carcinoma (ESCC). Methods The expressions of SOX17, Cyclin D1, and VE-cadherin, as well as VM, in tissues, were determined using immunohistochemistry. SOX17, Cyclin D1, and VE-cadherin mRNA in ESCC and their corresponding adjacent normal tissues were quantified using quantitative reverse transcription polymerase chain reaction analysis. Cell invasion, migration, and proliferation were determined after the silencing of VE-cadherin. SOX17, Cyclin D1, and VE-cadherin protein were quantified using Western blotting. Results The expression levels of SOX17, Cyclin D1, and VE-cadherin significantly correlated with the clinical characteristics of ESCC. After the VE-cadherin silencing, cell invasion, migration, and proliferation decreased, along with the Cyclin D1 levels, while the SOX17 levels increased. Conclusion SOX17, Cyclin D1, and VE-cadherin are involved in the development of ESCC.

Emerging Role of Non-Coding RNAs in Esophageal Squamous Cell Carcinoma. Int J Mol Sci 2019; 21:ijms21010258. [PMID: 31905958 PMCID: PMC6982002 DOI: 10.3390/ijms21010258] [Citation(s) in RCA: 49] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Revised: 12/04/2019] [Accepted: 12/14/2019] [Indexed: 12/14/2022] Open
Abstract
Esophageal squamous cell carcinoma (ESCC) is a highly prevalent tumor and is associated with ethnicity, genetics, and dietary intake. Non-coding RNAs (ncRNAs), specifically microRNAs (miRNAs), long ncRNAs (lncRNAs), and circular RNAs (circRNAs) have been reported as functional regulatory molecules involved in the development of many human cancers, including ESCC. Recently, several ncRNAs have been detected as oncogenes or tumor suppressors in ESCC progression. These ncRNAs influence the expression of specific genes or their associated signaling pathways. Moreover, interactions of ncRNAs are evident in ESCC, as miRNAs regulate the expression of lncRNAs, and further, lncRNAs and circRNAs function as miRNA sponges to compete with the endogenous RNAs. Here, we discuss and summarize the findings of recent investigations into the role of ncRNAs (miRNAs, lncRNAs, and circRNAs) in the development and progression of ESCC and how their interactions regulate ESCC development.

Abstract
INTRODUCTION Cervical cancer is one of the most common malignant tumors among women in the world. MicroRNA-449a (miR-449a) has been identified as a tumor suppressor gene in various cancers. Our present study aimed to explore the biological role of miR-449a in cervical cancer. METHODS The expression of miR-449a in cervical cancer tissues and cell lines was detected using real-time quantitative PCR. Kaplan-Meier survival analysis and a Cox regression assay were used to identify the prognostic significance of miR-449a in cervical cancer. A CCK-8 assay and a Transwell assay were performed to determine the impact of miR-449a on the proliferation, migration, and invasion of cervical cancer cells. RESULTS The expression of miR-449a was decreased in both cervical cancer tissues and cell lines. The decreased expression of miR-449a was significantly associated with lymph node metastasis, differentiation, and FIGO stage, as well as with poor survival. In vitro, transfection of miR-449a mimic into cervical cancer cells inhibited cell proliferation, migration, and invasion. CONCLUSION All of the results revealed that miR-449a functions as a suppressor gene and inhibits cell proliferation, migration, and invasion in cervical cancer. In addition, it may serve as a prognostic biomarker for cervical cancer.
