[PMID: 36737402 PMCID: PMC10040281 DOI: 10.1111/1759-7714.14812] [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: 11/30/2022] [Revised: 01/13/2023] [Accepted: 01/16/2023] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Esophageal cancer is a malignant tumor with a poor prognosis and high incidence. Circular RNAs (circRNAs) have been shown to be involved in the pathogenesis of cancers, including esophageal cancer. Here, we explored the precise role of circ_0003340 in esophageal cancer development. METHODS The expression levels of circ_0003340, miR-874-3p and enabled homolog (ENAH) were detected by quantitative real-time polymerase chain reaction and western blot. Subcellular localization and RNase R assays were used to characterize circ_0003340. Cell Counting Kit 8, flow cytometry, transwell assays were used to analyze cell proliferation, apoptosis, migration and invasion. The effect of circ_0003340 on tumor growth was assessed by tumor experiments in vivo. Dual-luciferase reporter assay was used to analyze the relationship between miR-874-3p and circ_0003340 or ENAH. RESULTS Circ_0003340 was mainly located in the cytoplasm and was upregulated in esophageal cancer tissues and cells. Circ_0003340 knockdown inhibited cell proliferation, migration, invasion, glucose consumption, and lactate production and induced cell apoptosis in esophageal cancer cells. Moreover, circ_0003340 knockdown suppressed tumor growth in vivo. MiR-874-3p was reduced in esophageal cancer tissues and cells, and it was a molecular mediator of circ_0003340 function in esophageal cancer cells. ENAH was identified as a direct and functional target of miR-874-3p in esophageal cancer cells. The promotion effect of circ_0003340 on ENAH was ameliorated by miR-874-3p. CONCLUSION The data demonstrated that circ_0003340 promoted the progression of esophageal cancer through miR-874-3p/ENAH axis, which might provide novel therapeutic targets for esophageal cancer intervention.

Int J Mol Sci 2022; 23:ijms231810952.

Abstract
Esophageal cancer (EC), an aggressive and poorly understood disease, is one of the top causes of cancer-related fatalities. GLOBOCAN 2020 reports that there are 544,076 deaths and 604,100 new cases expected worldwide. Even though there are various advancements in treatment procedures, this cancer has been reported as one of the most difficult cancers to cure, and to increase patient survival; treatment targets still need to be established. Nuclear receptors (NRs) are a type of transcription factor, which has a key role in several biological processes such as reproduction, development, cellular differentiation, stress response, immunity, metabolism, lipids, and drugs, and are essential regulators of several diseases, including cancer. Numerous studies have demonstrated the importance of NRs in tumor immunology and proved the well-known roles of multiple NRs in modulating proliferation, differentiation, and apoptosis. There are surplus of studies conducted on NRs and their implications in EC, but only a few studies have demonstrated the diagnostic and prognostic potential of NRs. Therefore, there is still a paucity of the role of NRs and different ways to target them in EC cells to stop them from spreading malignancy. This review emphasizes the significance of NRs in EC by discussing their diverse agonists as well as antagonists and their response to tumor progression. Additionally, we emphasize NRs’ potential to serve as a novel therapeutic target and their capacity to treat and prevent EC.

Abstract
PURPOSE AND OBJECTIVES To report survival and morbidity of a large homogeneous cohort of patients with a locally advanced esophageal or cardia carcinoma and put in evidence predictive factors of locoregional control and survival. PATIENTS AND METHODS Hundred and two patients were treated at the university hospital of Tours between 1990 and 2010 and received neo-adjuvant chemoradiation therapy with external irradiation (40Gy-44Gy) and two courses of chemotherapy (5-fluoro-uracile and cisplatine). Esophagectomy associated with lymph node dissection was performed about ten weeks after the end of chemoradiation therapy. RESULTS The median follow-up was 22.4 months [6-185 months]. The overall survival rates at 2 and 5years were 53% and 27%, respectively. The median overall survival was estimated at 27months. The overall 2-year survival between patients "responders" and patients "non-responders" was 67% vs 26%, respectively (P<0.0001). In case of histological response, there was a benefit in terms of overall survival (P<0.0001), locoregional control (P<0.0036) and disease-free survival (P<0.001). Overall survival at 2years was 64% for ypN0 group vs 32% for ypN1 group (P<0.0001). The median survival was estimated at 37months against 15months in the absence of lymph node involvement (P<0.0001). CONCLUSION Our results in terms of survival, tolerance and morbidity and mortality were comparable to those in the literature. Complete histological response of lymph node was associated with an improvement of local control, disease-free survival and overall survival.
