[PMID: 35736157 PMCID: PMC9228364 DOI: 10.3390/md20060353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 05/19/2022] [Accepted: 05/24/2022] [Indexed: 12/10/2022] Open
Abstract
Tissue factor pathway inhibitor-2 (TFPI-2) is a Kunitz-type serine protease inhibitor. Previous reports have shown that TFPI-2 plays an important role in innate immunity, and the C-terminal region of TFPI-2 proved to be active against a broad-spectrum of microorganisms. In this study, the TFPI-2 homologue (SsTFPI-2) of black rockfish (Sebastods schegelii) was analyzed and characterized, and the biological functions of its C-terminal derived peptide TS40 (FVSRQSCMDVCAKGAKQHTSRGNVRRARRNRKNRITYLQA, corresponding to the amino acid sequence of 187-226) was investigated. The qRT-PCR (quantitative real-time reverse transcription-PCR) analysis showed that the expression of SsTFPI-2 was higher in the spleen and liver. The expression of SsTFPI-2 increased significantly under the stimulation of Listonella anguillarum. TS40 had a strong bactericidal effect on L. anguillarum and Staphylococcus aureus. Further studies found that TS40 can destroy the cell structure and enter the cytoplasm to interact with nucleic acids to exert its antibacterial activity. The in vivo study showed that TS40 treatment could significantly reduce the transmission of L. anguillarum and the viral evasion in fish. Finally, TS40 enhanced the respiratory burst ability, reactive oxygen species production and the expression of immune-related genes in macrophages, as well as promoted the proliferation of peripheral blood leukocytes. These results provide new insights into the role of teleost TFPI-2.

Expression analysis of tissue factor pathway inhibitors TFPI-1 and TFPI-2 in Paralichthys olivaceus and antibacterial and anticancer activity of derived peptides. Vet Res 2021; 52:32. [PMID: 33632337 PMCID: PMC7905887 DOI: 10.1186/s13567-021-00908-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 01/25/2021] [Indexed: 03/09/2023] Open
Abstract
Tissue factor pathway inhibitors (TFPI), including TFPI-1 and TFPI-2, are Kunitz-type serine protease inhibitors that mainly inhibit the blood coagulation induced by tissue factors. Previous reports on teleost proved TFPI play important roles in innate immunity. In this study, two TFPI (PoTFPI-1 and PoTFPI-2) molecules from Japanese flounder (Paralichthys olivaceus) were analyzed and characterized for their expression patterns, antibacterial and anticancer activities of the C-terminal derived peptides. Quantitative real time RT-PCR analysis shows that constitutive PoTFPI-1 expression occurred, in increasing order, in the brain, muscle, spleen, gills, head kidney, blood, intestine, heart, and liver; PoTFPI-2 was expressed, in increasing order, in the brain, gills, head kidney, muscle, intestine, spleen, liver, heart, and blood. Under the stimulation of fish pathogens, both PoTFPI-1 and PoTFPI-2 expressions increased significantly in a manner that depended on the pathogens, tissue type, and infection stage. Furthermore, C-terminal peptides TP25 and TP26, derived from PoTFPI-1 and PoTFPI-2, respectively, were synthesized and proved to be active against Micrococcus luteus (for TP25 and TP26) and Staphylococcus aureus (for TP25) via retardation effects on bacterial nucleic acids. In addition, TP25 and TP26 also displayed significant inhibitory effects on human colon cancer cell line HT-29. These results reveal that both PoTFPI-1 and PoTFPI-2 play important roles in host innate immunity. The antibacterial activity and anticancer cells function of TP25 and TP26 will add new insights into the roles of teleost TFPI.

Yang Y, Zhang C, Li S, Liu J, Qin Y, Ge A. Tissue factor pathway inhibitor 2 suppresses the growth of thyroid cancer cells through by induction of apoptosis. Asia Pac J Clin Oncol 2020; 17:e48-e56. [PMID: 32043798 DOI: 10.1111/ajco.13298] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2018] [Accepted: 11/25/2019] [Indexed: 01/13/2023]
Abstract
BACKGROUND Tissue factor pathway inhibitor 2 (TFPI-2) has been recently identified as a tumor suppressor gene in several human cancers, whereas its role in thyroid cancer has been unclear. METHODS The TFPI-2 protein level in thyroid cancer tissues and cell lines (8305C and B-CPAP) were examined using immunohistochemistry and immunoblotting. The TFPI-2 promoter methylation was examined using methylation-specific polymerase chain reaction (MSP). Lentivirus containing TFPI-2 cDNA (Lenti-TFPI-2) was constructed to elevate TFPI-2 expression in 8305C and B-CPAP cells. The effects of Lenti-TFPI-2 on cell proliferation in vitro and in vivo were evaluated by MTT assay and mouse xenograft model. Annexin V/PI double staining assay was performed to detect the effect of Lenti-TFPI-2 on cell apoptosis. RESULTS TFPI-2 protein level were decreased in cancer tissues and lymph node metastasis, and TFPI-2 protein level is positively associated with survival time. The promoter of TFPI-2 is hypermethylated in cancer tissues. TFPI-2 mRNA and protein levels were abundant in normal human thyroid follicular cell line Nthy-ori 3-1 cells, whereas they were decreased in 8305C and B-CPAP cells. pcDNA-TFPI-2 elevated TFPI-2 mRNA and protein in 8305C and B-CPAP cells. TFPI-2 overexpression suppressed proliferation and induced apoptosis of 8305C and B-CPAP cells. CONCLUSIONS TFPI-2 inactivation may play a role in thyroid cancer tumorigenesis and development. TFPI-2 overexpression suppressed cell proliferation through induction of cell apoptosis, suggesting that TFPI-2 may serve as a novel and effective target for thyroid cancer therapy.

Integrin α9 Suppresses Hepatocellular Carcinoma Metastasis by Rho GTPase Signaling. J Immunol Res 2018; 2018:4602570.

Abstract
Integrin subunit alpha 9 (ITGA9) mediates cell-cell and cell-matrix adhesion, cell migration, and invasion through binding different kinds of extracellular matrix (ECM) components. However, its potential role and underlying molecular mechanisms remain unclear in hepatocellular carcinoma (HCC). Here, we found that ITGA9 expression was obviously decreased in patients with HCC, which was negatively correlated with HCC growth and metastasis. ITGA9 overexpression significantly inhibited cell proliferation and migration in vitro as well as tumor growth and metastasis in vivo. Our data demonstrated that the inhibitory effect of ITGA9 on HCC cell motility was associated with reduced phosphorylation of focal adhesion kinase (FAK) and c-Src tyrosine kinase (Src), disrupted focal adhesion reorganization, and decreased Rac1 and RhoA activity. Our data suggest ITGA9, as a suppressor of HCC, prevents tumor cell migration and invasiveness through FAK/Src-Rac1/RhoA signaling.

Conditional knockout of tissue factor pathway inhibitor 2 in vascular endothelial cells accelerates atherosclerotic plaque development in mice. Thromb Res 2015; 137:148-156. [PMID: 26603320 DOI: 10.1016/j.thromres.2015.11.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2015] [Revised: 11/02/2015] [Accepted: 11/06/2015] [Indexed: 01/12/2023]
Abstract
BACKGROUND Tissue factor pathway inhibitor-2 (TFPI-2) regulates matrix metalloproteinases activation and extracellular matrix degradation. Over-expression of TFPI-2 enhances atherosclerotic plaque stability. The aim of this study is to investigate the effect of conditional knockout (KO) of TFPI-2 in vascular endothelial cells on the initiation and development of atherosclerotic plaque. METHODS A Cre/mloxP conditional KO system and Tek-Cre mice were used to generate offsprings with monoallelic deletion of the TFPI-2 gene in endothelial cells. TFPI-2(fl/+)/Tek-Cre mice, TFPI-2(fl/+) mice and ApoE(-/-) mice (n=6 for each group) were included. Arteries were obtained. HE, EVG and anti-α-SMA staining were used to examine the morphology of vessel and plaque. Protein expression and phosphorylation were detected by Western blot or immunohistochemistry. RESULTS TFPI-2(fl/+)/Tek-Cre mice were generated. TFPI-2 level decreased to 40.68% in TFPI-2(fl/+)/Tek-Cre group. TFPI-2(fl/+)/Tek-Cre developed plaques when no plaque was found in TFPI-2(fl/+) mice. Compared with ApoE(-/-) group, TFPI-2(fl/+)/Tek-Cre group has smaller plaque area, decreased lipid content and less buried fibrous cap layers. MMP-2 and MMP-9 in TFPI-2(fl/+)/Tek-Cre group was higher than in TFPI-2(fl/+)group. The phosphorylation of PPAR-α and PPAR-γ was decreased in TFPI-2(fl/+)/Tek-Cre group. CONCLUSIONS A novel mouse model is presented and can be used to investigate the role of TFPI-2 in the process of atherosclerosis. Our findings suggest that monoallelic deletion of TFPI-2 gene in vascular endothelial cells leads to significant downregulation of TFPI-2. TFPI-2 deficiency may accelerate initiation of atherosclerotic lesion in mice. Elevated MMP-2 and 9 and decreased phosphorylation of PPAR-α and PPAR-γ may contribute to this phenotype.
