Pathol Res Pract 2024; 254:155095. [PMID: 38237399 DOI: 10.1016/j.prp.2024.155095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 09/22/2023] [Accepted: 01/02/2024] [Indexed: 02/12/2024]
Abstract
BACKGROUND To explore the role of Kelch repeat and BTB (POZ) domain containing 2 (KBTBD2) in Gastric cancer(GC) via studying the level of KBTBD2 and its impact on GC cells and mice model. METHODS Expression of KBTBD2 in GC was analyzed by analysis of TCGA data, Western blotting and Real-time quantitative polymerasechain reaction (RT-qPCR). The role of KBTBD2 on GC cells proliferation, viability, invasion, migration and apoptosis in vitro were assessed by using western blotting,RT-qPCR,CCK-8, EDU, Colony Formation Assay, Wound healing assay, Transwell, JC-1 mitochondrial membrane potential and flow cytometry assay, respectively. And levels of Bcl-2, BAX, PARP, E-cadherin, Vimentin, N-cadherin, EGFR, SOS1, NROS, BRAF,ERK1/2 and GAPDH were tested by western blotting. Relation of KBTBD2 and epidermal growth factor receptor (EGFR) was predicted by KEGG analysis. KBTBD2 gene GSEA enrichment was analyzed by using R language. Moreover, CCK-8, western blotting, and wound healing assays were used to verify the correlation of KBTBD2 and EGFR pathway. Finally, tumor growth in mice was also investigated. Cells proliferation, migration and apoptosis were detected by Ki67 staining, Tunnel staining and mouse lung metastasis model. RESULTS KBTBD2 was highly expressed in GC, and was related to poor prognosis. Moreover, silencing KBTBD2 suppressed GC cell proliferation, migration and invasion, while also inhibited the EMT, but promoted apoptosis. At the same time, KBTBD2 overexpression showed opposite results. In addition, KBTBD2 regulated the EGFR pathway. Further, silencing KBTBD2 inhibited tumor growth, cell proliferation and migration but promoted apoptosis in vivo, and KBTBD2 overexpression showed opposite results. CONCLUSIONS KBTBD2 was highly expressed in GC. KBTBD2 promotes the progress of GC by activating EGFR signal pathway. KBTBD2 may thus be a novel target for treating GC.

Down-regulation of HLA-B-associated transcript 3 impairs the tumoricidal effect of natural killer cells through promoting the T cell immunoglobulin and mucin domain-containing-3 signaling in a mouse head and neck squamous cell carcinoma model. Immunobiology 2021; 227:152127. [PMID: 34968777 DOI: 10.1016/j.imbio.2021.152127] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 07/09/2021] [Accepted: 07/25/2021] [Indexed: 11/22/2022]
Abstract
Head and neck squamous cell carcinoma (HNSCC) arises from the malignant mucosal epithelium of the oral cavity, pharynx, and larynx. Natural killer (NK) cells are fundamental immune cells shaping the anti-HNSCC response. Elucidation of the regulatory mechanisms of NK cell activity is crucial for understanding anti-HNSCC immunity. In this study, we characterized the expression and function of HLA-B-associated transcript 3 (Bat3) in NK cells in a mouse HNSCC model. We found that Bat3 expression was down-regulated in HNSCC-infiltrating NK cells. SCC VII, the mouse HNSCC cell line used in this model, induced Bat3 downregulation through direct cell-to-cell contact. By applying lentivirus-mediated silencing of Bat3, we discovered that Bat3 knockdown impaired the tumoricidal effect of NK cells on SCC VII cells and Hepa1-6RAE1, a genetically modified liver cancer cell line. Furthermore, Bat3 knockdown resulted in a significant decrease in perforin, granzyme B, interferon-γ, and tumor necrosis factor-α in NK cells upon co-culture with SCC VII cells. Further investigations revealed that Bat3 knockdown promoted the binding of T cell immunoglobulin and mucin domain-containing-3 (Tim-3) to Fyn and thus activated the Tim-3 signaling. Blockade of Tim-3 with a neutralizing Tim-3 antibody counteracted the effect of Bat3 knockdown on NK cell cytotoxicity. Taken together, our data suggest that HNSCC might down-regulate Bat3 expression to augment Tim-3 signaling and ultimately suppress the tumoricidal activity of NK cells. This study unveils a novel mechanism by which HNSCC evades NK cell killing, and sheds light on designing novel anti-HNSCC immunotherapy targeting Bat3 and Tim-3 signaling.

[PMID: 33859498 PMCID: PMC8043788 DOI: 10.2147/cmar.s301844] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 03/22/2021] [Indexed: 02/05/2023] Open
Abstract
PURPOSE This study aimed to explore the function and clinical significance of AVL9 in colorectal cancer (CRC). MATERIALS AND METHODS The GEO, TCGA, and GEPIA databases were searched to evaluate the expression level of AVL9, while the SurvExpress online tool was used to explore its related clinical survival prognosis. The cBioPortal and LinkedOmics databases were used to identify AVL9 expression-related genes. Protein-protein interaction (PPI) networks were analyzed using Cytoscape 3.7.1 and DAVID6.8, which was used to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genome (KEGG) signal pathway enrichment. The immunohistochemistry of AVL9 in CRC was detected using an online tool protein atlas. RNA isolation and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) assays were used to detect AVL9 expression in tissue and plasma samples. RESULTS Our study confirmed that AVL9 was highly expressed in CRC lesions versus the adjacent normal tissues (P < 0.001). High AVL9 expression was negatively associated with survival outcomes (P < 0.05). GO analysis showed that AVL9 expression-related genes were enriched in single organismal cell-cell adhesion, post-transcriptional regulation of gene expression, and negative regulation of the vascular endothelial growth factor receptor signaling pathway (P < 0.05). On a KEGG pathway analysis, these genes were mainly involved in progesterone-mediated oocyte maturation, axon guidance, the insulin signaling pathway, and the ubiquitin-mediated proteolysis signaling pathways (P < 0.05). In the PPI analysis, the KBTBD2, KIAA1147, EPDR1, and RNF216 genes interacted with AVL9, and GEPIA predicted that their expression levels were all positively correlated with AVL9. Furthermore, a clinicopathological parameter analysis found that high AVL9 expression was positively correlated with differentiation and TNM stage. RT-qPCR analysis further showed that plasma AVL9 expression was upregulated in CRC patients versus healthy controls. CONCLUSION AVL9 could serve as a potential biomarker and therapeutic target for CRC.

Abstract
NK-92 cell line has been used as anti-tumor cytotoxic effector cells in immunotherapy. Leucine-rich repeats and calponin homology domain containing 1 (LRCH1) is a novel gene of which the function is unclear. In the present study, we investigated the role of LRCH1 in NK-92 cell cytotoxicity. LRCH1 was ablated in NK-92 cells through CRISP-Cas9-mediated knockout. LRCH1 knockout did not influence the basal behavior of NK-92 cells such as cell survival, expression of natural cytotoxicity receptors, and proliferation. However, upon the contact with tumor cells, LRCH1 knockout promoted NK-92 cell cytotoxicity to tumor cells. Besides, LRCH1 knockout increased the production of cytotoxic mediators such as IFN-γ, TNF-α, IL-2, and granzyme B in NK-92 cells after tumor cell contact. Similarly, LRCH1 knockout increased the production of cytokines and granzyme B upon NKp30 engagement. Further experiments revealed that LRCH1 knockout enhanced the activation of Src and Lck kinase which are important for natural killer cell cytotoxicity. The in vivo assay confirmed the up-regulation of the tumoricidal activity of LRCH1-/- NK-92 cells, as demonstrated by more robust tumor cell killing. Importantly, human primary natural killer cells exhibited a similar increase in the production of IFN-γ and TNF-α when LRCH1 was knocked out. In conclusion, our study revealed the role of LRCH1 as a negative regulator of NK-92 cell cytotoxicity.

Abstract
Hepatocellular carcinoma (HCC) is the third most lethal cancer in the world. Natural killer (NK) cell-mediated immunity is crucial for tumor surveillance and therapy. Characterization of the regulatory mechanisms of NK cell function is important for developing novel immunotherapies against HCC. In this study, we used a chemical-induced mouse HCC model to identify the upregulation of Sirtuin2 (SIRT2) in liver NK cells. In particular, SIRT2 was predominantly expressed in liver CD94+ NK cells. The HCC liver microenvironment induced SIRT2 expression in NK cells. In addition, overexpression of exogenous SIRT2 significantly upregulated the production of cytokines and cytotoxic mediators in activated NK cells. Consistently, SIRT2-overexpressing NK cells showed a stronger tumoricidal effect on hepatoma cells. Moreover, SIRT2 remarkably promoted the phosphorylation of Extracellular-signal-regulated kinase 1/2 (Erk1/2) and p38 Mitogen-activated protein kinases (MAPK) in activated NK cells. SIRT2 knockdown in liver CD94+ NK cells impaired their cytotoxic effect on hepatoma cells. Our study indicates that SIRT2 enhances the tumoricidal activity of liver NK cells in HCC.

Exp Ther Med 2018; 16:83-92. [PMID: 29977357 PMCID: PMC6030861 DOI: 10.3892/etm.2018.6140] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2017] [Accepted: 03/05/2018] [Indexed: 12/16/2022] Open
Abstract
Postoperative immunosuppression is associated with the recurrence and metastasis of esophageal squamous cell carcinoma (ESCC). Propofol is a commonly used intravenous anesthetic and has been reported to be associated with immunosuppression; however, little is known about its effect on innate immune cells during the postoperative period in patients with ESCC. The aim of the present study was to investigate the effects of propofol on the phenotype and cytotoxicity of natural killer (NK) cells derived from the peripheral blood of patients with ESCC. The percentage, phenotype and function of NK cells were compared between patients with ESCC and healthy volunteers using flow cytometry. NK cells were negatively sorted using magnetic beads and cocultured with propofol to assess changes in phenotype and function. The results revealed that the percentage of NK cells was significantly increased in the peripheral blood of patients with ESCC, while their activity and cytotoxicity were impaired. NK cells were successfully separated from peripheral blood in vitro and it was demonstrated that propofol enhanced their activity by influencing the expression of activating or inhibitory receptors. Furthermore, propofol was able to increase the cytotoxicity of NK cells from the peripheral blood of patients with ESCC. These results suggest that propofol is able to improve the function of NK cells in patients with ESCC and may therefore be an appropriate anesthetic for ESCC surgery.
