Abstract
Rutin is a natural flavonoid compound that is widely found in a variety of plants and has a variety of biological effects, including anti-inflammatory, antioxidant, and anti-tumor effects. Rutin has been shown to have anti-tumor effects in a variety of cancers, but its effects on gastric cancer need to be further explored. The aim of this study was to explore the effects of Rutin on gastric cancer cells and the potential molecular regulatory mechanisms. Gastric cancer cells (AGS and MGC803) were treated with different concentrations of Rutin. Cell proliferation, apoptosis, migration, and invasion were determined by MTT, flow cytometry, scratch assay, and Transwell analysis, respectively. Cell epithelial mesenchymal transition (EMT) markers and Wnt/β-catenin pathway were analyzed by RT-qPCR and western blot assay. The results showed that Rutin significantly inhibited the proliferation, migration and invasion ability of gastric cancer cells, induced apoptosis, and suppressed the EMT process. Further experiments revealed that Rutin achieved the effect of inhibiting the biological behavior of gastric cancer cells by suppressing the activation of the Wnt/β-catenin pathway. Therefore, Rutin may become a potential therapeutic candidate for gastric cancer.

Abstract
The increased expression of Copine 1 (CPNE1) has been observed in various cancers, which promotes cell proliferation, apoptosis, and radio resistance. However, the potential mechanism of CPNE1 in nasopharyngeal carcinoma (NPC) remains elusive. Consequently, our objective was to investigate the role of CPNE1 in regulating proliferation and radio resistance of NPC. CPNE1 expression in NPC and normal patients were obtained from Cancer Genome Atlas (TCGA) database. An elevated CPNE1 was observed in NPC patients and cells (C666-1, SUNE-1, and HNE-1). Then, C666-1 and SUNE-1 cells were subjected to si-CPNE1 under different radiations (0-8 Gy). Cell growth and proliferation were measured by CCK8 and EDU assays, which demonstrated si-CPNE1 suppressed proliferation. Colony formation was performed to detect cell viability under different radiation therapy and survival curve of cell was plotted, which indicated that CPNE1 knockdown improved cell radiosensitivity. Additionally, flow cytometry showed silence of CPNE1 enhanced apoptosis rate in radiated cells. To further investigate the mechanisms of CPNE1 regulating NPC, the expression of activated phosphate Akt (p-Akt) was assessed through western blotting. We observed elevated p-Akt in si-CPNE1 transfected C666-1 and SUNE-1 cells. In conclusion, these results demonstrated that CPNE1 expression is elevated in nasopharyngeal carcinoma cells, and its silencing could attenuate nasopharyngeal carcinoma advancement and improve radiosensitivity to radiation therapy by controlling Akt activation.

[PMID: 37747823 PMCID: PMC10773812 DOI: 10.1093/carcin/bgad067] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Revised: 09/05/2023] [Accepted: 09/22/2023] [Indexed: 09/27/2023] Open
Abstract
OBJECTIVE Copine 1 (CPNE1), a membrane-binding protein, influences the prognosis of various cancers. According to cBioPortal, CPNE1 amplification is a prevalent genetic mutation in ovarian cancer but with unknown oncogenic mechanism. METHODS This study analysed the CPNE1 expression in ovarian cancer using online datasets, as validated by immunohistochemistry (IHC), quantitative polymerase chain reaction (qPCR) and western blotting. Concurrently, the prognostic value of CPNE1 was accessed. Cell Counting Kit-8, colony formation, transwells and xenograft experiments were performed to evaluate the functions of CPNE1 during ovarian cancer carcinogenesis. CPNE1 and its related genes were analysed by g:Profiler and Tumour Immune Estimation Resource. Furthermore, human monocytic THP-1 cells were co-cultured with ES2 cells to investigate the effect of CPNE1 on macrophage polarization. RESULTS The results of bioinformatic analysis, IHC, qPCR and western blotting indicated a higher CPNE1 in ovarian cancer. CPNE1 overexpression demonstrated an association with a poor prognosis of ovarian cancer. Functionally, CPNE1 overexpression increased ES2 and SKOV3 cell proliferation, invasion and migration in vitro and promoted ovarian tumour xenograft growth in vivo, while CPNE1 knockdown led to opposite effects. Additionally, CPNE1 expression demonstrated an association with immune cell infiltration in ovarian cancer, especially macrophage. CPNE1 promoted protumour M2 macrophage polarization by upregulating cluster of differentiation 163 (CD163), CD206 and interleukin-10. CONCLUSIONS Our study revealed that CPNE1 mediated M2 macrophage polarization and provided a therapeutic target for ovarian cancer.

Front Cell Dev Biol 2023; 11:1157269. [PMID: 37077419 PMCID: PMC10106647 DOI: 10.3389/fcell.2023.1157269] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Accepted: 03/20/2023] [Indexed: 04/05/2023] Open
Abstract
Background: Elevated expression of Copine-1 (CPNE1) has been proved in various cancers; however, the underlying mechanisms by which it affects clear cell renal cell carcinoma (ccRCC) are unclear.Methods: In this study, we applied multiple bioinformatic databases to analyze the expression and clinical significance of CPNE1 in ccRCC. Co-expression analysis and functional enrichment analysis were investigated by LinkedOmics, cBioPortal and Metascape. The relationships between CPNE1 and tumor immunology were explored using ESTIMATE and CIBERSORT method. In vitro experiments, CCK-8, wound healing, transwell assays and western blotting were conducted to investigate the effects of gain- or loss-of-function of CPNE1 in ccRCC cells.Results: The expression of CPNE1 was notably elevated in ccRCC tissues and cells, and significantly correlated with grade, invasion range, stage and distant metastasis. Kaplan–Meier and Cox regression analysis displayed that CPNE1 expression was an independent prognostic factor for ccRCC patients. Functional enrichment analysis revealed that CPNE1 and its co-expressed genes mainly regulated cancer-related and immune-related pathways. Immune correlation analysis showed that CPNE1 expression was significantly related to immune and estimate scores. CPNE1 expression was positively related to higher infiltrations of immune cells, such as CD8+ T cells, plasma cells and regulatory T cells, exhibited lower infiltrations of neutrophils. Meanwhile, elevated expression of CPNE1 was characterized by high immune infiltration levels, increased expression levels of CD8+ T cell exhaustion markers (CTLA4, PDCD1 and LAG3) and worse response to immunotherapy. In vitro functional studies demonstrated that CPNE1 promoted proliferation, migration and invasion of ccRCC cells through EGFR/STAT3 pathway.Conclusion: CPNE1 is a reliable clinical predictor for the prognosis of ccRCC and promotes proliferation and migration by activating EGFR/STAT3 signaling. Moreover, CPNE1 significantly correlates with immune infiltration in ccRCC.
