Diagnostic utility of trefoil factor families for the early detection of lung cancer and their correlation with tissue expression. Oncol Lett 2023; 25:139. [PMID: 36909373 PMCID: PMC9996639 DOI: 10.3892/ol.2023.13725] [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: 07/27/2022] [Accepted: 12/22/2022] [Indexed: 02/23/2023] Open
Abstract
Trefoil factors (TFFs) are upregulated in numerous types of cancer, including those of the breast, the colon, the lung and the pancreas, suggesting their potential utility as biomarkers for screening. In the present study, the clinical relevance of serum or urinary TFFs as biomarkers were comprehensively evaluated and the correlation with TFF expression levels in lung cancer tissue was examined. Serum and urine were collected from 199 patients with lung cancer and 198 healthy individuals. Concentrations of serum and urinary TFF1, TFF2 and TFF3 were measured using ELISA and the potential of TFF levels to discriminate between cancer and non-cancer samples was evaluated. In 100 of the cancer cases, expression of TFF1-3 was analyzed using immunohistochemical staining of paraffin sections. Furthermore, the relationship between TFF levels and clinicopathological factors among these cancer cases was analyzed using immunohistochemistry of tissue specimens, quantified and statistically analyzed. While serum levels of all TFFs measured using ELISA were significantly higher in patients with lung cancer compared with those in healthy individuals, urinary TFFs were lower. Areas under the curve (AUC) of the receiver operating characteristic curves for serum/urinary TFF1, TFF2 and TFF3 were 0.709/0.594, 0.722/0.501 and 0.663/0.665, respectively. Furthermore, the combination of serum TFF1, TFF2, TFF3 and urinary TFF1 and TFF3 demonstrated the highest AUC (0.826). In the clinicopathological analysis, serum TFF1 was higher in the early pathological T-stage (pTis/1/2) compared with the later stage (pT3/4) and TFF2 was higher in the pN0/1 than the pN2 group. With regards to the histological types, urinary TFF1 was higher in squamous cell carcinoma than adenocarcinoma (AC), but TFF2 tended to be higher in AC. Using immunohistochemical analysis, although TFF1 and TFF3 expression showed positive correlation with serum concentrations, TFF2 was inversely correlated. In conclusion, serum and urinary TFF levels are promising predictive biomarkers, and their measurements provide a useful in vivo and non-invasive diagnostic screening tool. In particular, TFF1 and TFF3 could be surrogate markers of clinicopathological profiles of human lung cancer.

Abstract
Trefoil factor 3 (TFF3, also known as intestinal trefoil factor) is a small-molecule peptide containing a typical trefoil structure. TFF3 has several biological effects, such as wound healing, immune regulation, neuroprotection, and cell migration and proliferation promotion. Although TFF3 binding sites were identified in rat kidneys more than a decade ago, the specific effects of this small-molecule peptide on kidneys remain unclear. Until recently, much of the research on TFF3 in the kidney field has focused exclusively on its role as a biomarker. Notably, a large prospective randomized study of patients with 29 common clinical diseases revealed that chronic kidney disease (CKD) was associated with the highest serum TFF3 levels, which were 3-fold higher than in acute gastroenteritis, which had the second-highest levels. Examination of each stage of CKD revealed that urine and serum TFF3 levels significantly increased with the progression of CKD. These results suggest that the role of TFF3 in CKD needs further research. The present review summarizes the renal physiological expression, biological functions, and downstream signaling of TFF3, as well as the upstream events that lead to high expression of TFF3 in CKD.

Abstract
BACKGROUND & AIMS Distal cholangiocarcinoma (dCCA) are a group of epithelial cell malignancies that occurs at the distal common bile duct, and account for approximately 40% of all cholangiocarcinoma cases. dCCA remains a highly lethal disease as it typically features remarkable cellular heterogeneity. A comprehensive exploration of cellular diversity and the tumor microenvironment is essential to depict the mechanisms driving dCCA progression. METHODS Single-cell RNA sequencing was used here to dissect the heterogeneity landscape and tumor microenvironment composition of human dCCAs. Seven human dCCAs and adjacent normal bile duct samples were included in the current study for single-cell RNA sequencing and subsequent validation approaches. Additionally, the results of the analyses were compared with bulk transcriptomic datasets from extrahepatic cholangiocarcinoma and single-cell RNA data from intrahepatic cholangiocarcinoma. RESULTS We sequenced a total of 49,717 single cells derived from human dCCAs and adjacent tissues, identifying 11 distinct cell types. Malignant cells displayed remarkable inter- and intra-tumor heterogeneity with 5 distinct subsets were defined in tumor samples. The malignant cells displayed variable degree of aneuploidy, which can be classified into low- and high-copy number variation groups based on either amplification or deletion of chr17q12 - chr17q21.2. Additionally, we identified 4 distinct T lymphocytes subsets, of which cytotoxic CD8+ T cells predominated as effectors in tumor tissues, whereas tumor infiltrating FOXP3+ CD4+ regulatory T cells exhibited highly immunosuppressive characteristics. CONCLUSION Our single-cell transcriptomic dataset depicts the inter- and intra-tumor heterogeneity of human dCCAs at the expression level.

Abstract
OBJECTIVE To assess the diagnostic value of Trefoil factor 3 (TFF3) and the correlation between TFF3 expression and clinicopathological features in patients with gastric cancer (GC). METHODS PubMed, The Cochrane, EMbase, and Web of Science were retrieved comprehensively to collect relevant literature. The search ended on 31 May 2020. All data were analyzed using PubMed, The Cochrane, EMbase, and Web of Science were retrieved to collect relevant articles. All data from the included studies were subjected to meta-analysis using Stata 12.0 software. RESULTS Seventeen studies involved 4654 subjects were included. For the diagnostic value of TFF3 for GC, the sensitivity, specificity, and AUC were 0.71, 0.80, and 0.80, respectively. For the clinicopathological value of TFF3, tissue TFF3 expression showed a higher risk of lymph node metastasis (OR 2.20, 95% CI 1.75-2.78, p < 0.001) and muscularis propria invasion (≥T2) (1.51, 1.13-2.03, p = 0.006), as well as worse TNM stage (2.26, 1.63-3.12, p < 0.001) and histological type (1.72, 1.34-2.20, p < 0.001), while no apparent relationship was found for serous membrane invasion (T4), venous invasion, and peritoneal metastasis. CONCLUSION TFF3 may be a promising biomarker for GC, and the TFF3 expression is likely to be involved in the invasion, metastasis, and differentiation of GC.

Abstract
Trefoil factor family peptides (TFF1, TFF2, and TFF3) are key players in protecting, maintaining, and repairing the gastrointestinal tract. Accordingly, they have the therapeutic potential to treat and prevent a variety of gastrointestinal disorders associated with mucosal damage. TFF peptides share a conserved motif, including three disulfide bonds that stabilize a well-defined three-loop-structure reminiscent of a trefoil. Although multiple functions have been described for TFF peptides, their mechanisms at the molecular level remain poorly understood. This review presents the status quo of TFF research relating to gastrointestinal disorders. Putative TFF receptors and protein partners are described and critically evaluated. The therapeutic potential of these peptides in gastrointestinal disorders where altered mucosal biology plays a crucial role in the underlying etiology is discussed. Finally, areas of investigation that require further research are addressed. Thus, this review provides a comprehensive update on TFF literature as well as guidance toward future research to better understand this peptide family and its therapeutic potential for the treatment of gastrointestinal disorders.

Abstract
Macrophage-based immune dysregulation plays a critical role in development of delayed gastric emptying in diabetic mice. Loss of anti-inflammatory macrophages and increased expression of genes associated with pro-inflammatory macrophages has been reported in full-thickness gastric biopsies from gastroparesis patients. We aimed to determine broader protein expression (proteomics) and protein-based signaling pathways in gastric biopsies of diabetic (DG) and idiopathic gastroparesis (IG) patients. Additionally, we determined correlations between protein expressions, gastric emptying, and symptoms. Full-thickness gastric antrum biopsies were obtained from nine DG patients, seven IG patients, and five nondiabetic controls. Aptamer-based SomaLogic tissue scan that quantitatively identifies 1,305 human proteins was used. Protein fold changes were computed, and differential expressions were calculated using Limma. Ingenuity pathway analysis and correlations were carried out. Multiple-testing corrected P < 0.05 was considered statistically significant. Seventy-three proteins were differentially expressed in DG, 132 proteins were differentially expressed in IG, and 40 proteins were common to DG and IG. In both DG and IG, "Role of Macrophages, Fibroblasts and Endothelial Cells" was the most statistically significant altered pathway [DG false discovery rate (FDR) = 7.9 × 10-9; IG FDR = 6.3 × 10-12]. In DG, properdin expression correlated with GCSI bloating (r = -0.99, FDR = 0.02) and expressions of prostaglandin G/H synthase 2, protein kinase C-ζ type, and complement C2 correlated with 4 h gastric retention (r = -0.97, FDR = 0.03 for all). No correlations were found between proteins and symptoms or gastric emptying in IG. Protein expression changes suggest a central role of macrophage-driven immune dysregulation in gastroparesis, specifically, complement activation in diabetic gastroparesis.NEW & NOTEWORTHY This study uses SOMAscan, a novel proteomics assay for determination of altered proteins and associated molecular pathways in human gastroparesis. Seventy-three proteins were changed in diabetic gastroparesis, 132 in idiopathic gastroparesis compared with controls. Forty proteins were common in both. Macrophage-based immune dysregulation pathway was most significantly affected in both diabetic and idiopathic gastroparesis. Proteins involved in the complement and prostaglandin synthesis pathway were associated with symptoms and gastric emptying delay in diabetic gastroparesis.

Abstract
High salt (HS) dietary intake leads to impaired vascular endothelium-dependent responses to various physiological stimuli, some of which are mediated by arachidonic acid (AA) metabolites. Transgenic Tff3−/− gene knockout mice (Tff3−/−/C57BL/6N) have changes in lipid metabolism which may affect vascular function and outcomes of stroke. We aimed to study the effects of one week of HS diet (4% NaCl) on vascular function and stroke induced by transient occlusion of middle cerebral artery in Tff3−/− and wild type (WT/C57BL/6N) mice. Flow-induced dilation (FID) of carotid artery was reduced in WT-HS mice, but not affected in Tff3−/−-HS mice. Nitric oxide (NO) mediated FID. NO production was decreased with HS diet. On the contrary, acetylcholine-induced dilation was significantly decreased in Tff3−/− mice on both diets and WT-HS mice. HS intake and Tff3 gene depletion affected the structural components of the vessels. Proteomic analysis revealed a significant effect of Tff3 gene deficiency on HS diet-induced changes in neuronal structural proteins and acute innate immune response proteins’ expression and Tff3 depletion, but HS diet did not increase the stroke volume, which is related to proteome modification and upregulation of genes involved mainly in cellular antioxidative defense. In conclusion, Tff3 depletion seems to partially impair vascular function and worsen the outcomes of stroke, which is moderately affected by HS diet.

TFF3 and TFF1 expression levels are elevated in colorectal cancer and promote the malignant behavior of colon cancer by activating the EMT process. Int J Oncol 2019; 55:789-804. [PMID: 31432157 PMCID: PMC6741840 DOI: 10.3892/ijo.2019.4854] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Accepted: 06/27/2019] [Indexed: 12/19/2022] Open
Abstract
Reports on the roles of the secreted trefoil factor (TFF)1 and 3 in colorectal cancer (CRC) and their underlying mechanisms of action in tumorigenesis are not common and are controversial. In the present study, the mRNA expression and promoter methylation of TFF1 and TFF3 in cancer and adjacent normal tissues were investigated, and their association with other clinical factors and patient prognosis were evaluated. Moreover, the association between TFF3 and epithelial mesenchymal transition (EMT) was explored by overexpressing or inhibiting TFF3 expression. The results revealed that the mRNA level of TFF1 and TFF3 in the cancer tissues was significantly higher than that in the matched adjacent normal tissues (P=0.034 and P=0.007, respectively), and a higher expression of TFF3, but not TFF1, was predominantly associated with clinicopathological factors and a poorer prognosis. No correlation was observed between promoter methylation and the expression of TFF1 or TFF3. The overexpression of TFF3 promoted the proliferation, migration and invasiveness of HT29 cells, and induced an increase in the expression of Twist1, Snail and Vimentin, while causing a decrease in E-cadherin expression. On the contrary, the knockdown of TFF3 resulted in opposite effects in the LoVo cells. On the whole, the findings of this study indicate that TFF3 may be a promising new factor for the estimation of the survival of patients with CRC, and may promote the malignant progression of CRC by activating the EMT process. Therefore, TFF3 may be a future potential therapeutic target for CRC.

Abstract
Diagnostic markers facilitate more selective screening and treatment strategies for ulcerative colitis (UC)-associated cancer (UCAC). The expression of trefoil factor-3 (TFF3), which is involved in mucosal protection and repair in the gastrointestinal tract, was analyzed and its significance for UCAC was evaluated. A total of 145 patients with UC who underwent proctocolectomies were enrolled, including 15 patients (10.8%) with UCAC. TFF3 expression in the rectal mucosa and in cancer cells was assessed using immunohistochemistry, and the expression in UCAC and sporadic colorectal cancer was compared. Analyzing the mucinous granules of goblet cells located in crypts revealed that the non-cancerous rectal mucosa of patients with UCAC had significantly lower mean TFF3 staining scores compared with patients with UC without UCAC or patients with sporadic cancer. TFF3 staining score was revealed to be an independent predictor of UCAC development. These results indicated that low TFF3 expression in the rectal mucosa was associated with the development of UCAC. Thus, TFF3 expression in the rectal mucosa may be a useful biomarker for monitoring patients with UC.

Screening Biomarker as an Alternative to Endoscopy for the Detection of Early Gastric Cancer: The Combination of Serum Trefoil Factor Family 3 and Pepsinogen. Gastroenterol Res Pract 2018; 2018:1024074. [PMID: 29977284 PMCID: PMC5994275 DOI: 10.1155/2018/1024074] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2017] [Accepted: 04/03/2018] [Indexed: 12/12/2022] Open
Abstract
Objective The serum pepsinogen test has limitation in its predictive power as a noninvasive biomarker for gastric cancer screening. We aimed to investigate whether the combination of TFF3 and pepsinogen could be an effective biomarker for the detection of gastric cancer even in the early stages. Methods In total, 281 patients with early gastric cancer (EGC), who underwent endoscopic submucosal dissection in Korea, and 708 healthy individuals from Japan were enrolled in the derivation cohort. The validation cohort included 30 Korean patients with EGC and 30 Korean healthy control blood donors. Serum TFF3 levels were examined using enzyme-linked immunosorbent assay. Results Using a cutoff of 6.73 ng/mL in the derivation cohort, the sensitivity of the combination of tests for EGC detection was superior (87.5%) to that of TFF3 (80.4%) or pepsinogen test alone (39.5%). Similarly, in the validation cohort, the sensitivity of TFF3 plus pepsinogen was higher (90.4%) than that of TFF3 (80.0%) or pepsinogen test alone (33.3%). Conclusion The combination of serum TFF3 and pepsinogen is a more effective noninvasive biomarker for gastric cancer detection compared with pepsinogen or TFF3 alone, even in EGC. This trial is registered with NCT03046745.

Abstract
AIM To detect the expression of trefoil factors (TFFs) and TWIST1 in colorectal cancer (CRC) and analyze their correlation with metastasis and survival.
METHODS This study examined the expression of TFF1, TFF3 and TWIST1 in a total of 75 tumor samples, 47 matched normal samples (15 cm from the lesion margin), 30 metastatic lymph nodes, and 10 liver metastatic cancer samples from patients with CRC. The relationship was then analyzed between the protein expression and different clinical records. TFF1, TFF3, TWIST1,E-cadherin, vimentin and β-catenin mRNA and protein expression levels were measured in colon cancer cell lines with different metastatic potentials (HIEC, HT29, SW620, and LoVo cells), and the correlation of the expression levels with epithelial-mesenchymal transition (EMT) was discussed.
RESULTS It was found that 66.7% (50/75), 78.7% (59/75) and 54.7% (41/75) of tumor tissue samples exhibited positive staining for TFF1, TFF3 and TWIST1 and so did 27.3% (13/47), 100% (47/47) and 17% (8/47) of adjacent normal colorectal tissues. Compared with adjacent normal tissues, significant differences were found in the expression of all three proteins in different cancerous tissues (P < 0.05). Higher expression of TFF3 and TWIST1 was significantly correlated with lymph node metastasis (P = 0.034, P = 0.000), advanced stage (P = 0.031, P = 0.003), and poorer survival (P = 0.042 for the TFF3 group, P = 0.003 for the TWIST1 group). The expression of TFF3 and TWIST1 in cancer cell lines was higher than that in HIEC (a normal human intestinal epithelial cell line)(P < 0.05), and the expression intensity demonstrated a tendency to rise with increased metastatic potential both at the protein and mRNA levels. However, TFF1 expression demonstrated the opposite tendency. It was also observed that the expression of E-cadherin and β-catenin tended to decrease while that of vimentin, TWIST1 and Snail tended to rise with the increase in metastatic potential.
CONCLUSION The expression of TFF3 and TWIST1 might be associated with the survival of patients with CRC after curative resection and might be pivotal predictors of disease progression. TFF3 may be correlated to the invasiveness of CRC.

Abstract
Emerging data show that serum trefoil factor 3 (TFF3) alone and combined with the serum pepsinogen (PG) test can increase the diagnostic yield of gastric cancer. We aimed to evaluate the diagnostic value of serum TFF3 for the screening of gastric cancer in Korean patients, especially for the screening of the diffuse type of gastric cancer, and compared TFF3 to the serum PG test. We enrolled 25 healthy controls and 79 subjects with gastric cancer who underwent endoscopic resection or surgery from June 2006 to June 2015. Data about age, sex, histological type according to the Lauren classification, stage of gastric cancer, and status of H. pylori were collected. Serum levels of PG I and PG II were measured by the latex-enhanced turbidimetric immunoassay, and serum TFF3 levels were measured by enzyme-linked immunosorbent assay. The optimal cutoff value of serum TFF3 was ≥8.9 ng/mL to diagnose gastric cancer, with 73.4 % sensitivity and 92.0 % specificity, which were higher than those of the serum PG I/II ratio, with 69.6 % sensitivity and 68.0 % specificity. The optimal sensitivity and specificity of serum TFF3 for the diagnosis of diffuse-type gastric cancer were 68.0 and 92.0 %, respectively, which were lower than those for the diagnosis of intestinal-type gastric cancer (75.6 and 100 %, respectively). Serum TFF3 is a more stable and useful marker than the serum PG test for the screening of gastric cancer in Korean patients. Serum TFF3 showed good diagnostic power in detecting both intestinal- and diffuse-type gastric cancer although it showed decreased power in diffuse type.

Abstract
OBJECTIVE Very little is known about the role of trefoil factors (TFFs) in salivary gland tumors, and TFF immunoexpression has never been investigated in such tumors. The aim of this study was to evaluate TFF immunoexpression in benign and malignant salivary gland tumors. MATERIALS AND METHODS Benign (n = 25) and malignant (n = 25) salivary gland tumor specimens were included in this study, using mucocele (n = 25) specimens as a control group. Immunohistochemical staining was performed to evaluate the expression of TFFs (TFF1, TFF2, and TFF3) by semiquantitative means. RESULTS Expression of TFF1, TFF2, and TFF3 was significantly increased in benign (p = 0.001, p = 0.005, p < 0.001, respectively) and malignant (p < 0.001, p < 0.001, p < 0.001, respectively) groups as compared with the control group. Patterns of co-expression between TFF1/TFF2, TFF2/TFF3, and TFF1/TFF3 were different among the three groups. CONCLUSIONS The present study provided new information showing that all TFFs were significantly increased in benign and malignant salivary gland tumors, and overexpression of TFFs could be associated with neoplastic transformation in salivary gland tissues. CLINICAL RELEVANCE Overexpression of TFFs may be useful as biomarkers in terms of differential diagnosis between salivary gland tumors and other oral neoplasms for which clinical manifestations are indistinguishable.

Abstract
Mammary carcinoma cells produce pro-angiogenic factors to stimulate angiogenesis and tumor growth. Trefoil factor-3 (TFF3) is an oncogene secreted from mammary carcinoma cells and associated with poor prognosis. Herein, we demonstrate that TFF3 produced in mammary carcinoma cells functions as a promoter of tumor angiogenesis. Forced expression of TFF3 in mammary carcinoma cells promoted proliferation, survival, invasion and in vitro tubule formation of human umbilical vein endothelial cells (HUVEC). MCF7-TFF3 cells with forced expression of TFF3 generated tumors with enhanced microvessel density as compared to tumors formed by vector control cells. Depletion of TFF3 in mammary carcinoma cells by siRNA concordantly decreased the angiogenic behavior of HUVEC. Forced expression of TFF3 in mammary carcinoma cells stimulated IL-8 transcription and subsequently enhanced IL-8 expression in both mammary carcinoma cells and HUVEC. Depletion of IL-8 in mammary carcinoma cells with forced expression of TFF3, or antibody inhibition of IL-8, partially abrogated mammary carcinoma cell TFF3-stimulated HUVEC angiogenic behavior in vitro, as did inhibition of the IL-8 receptor, CXCR2. Depletion of STAT3 by siRNA in MCF-7 cells with forced expression of TFF3 partially diminished the angiogenic capability of TFF3 on stimulation of cellular processes of HUVEC. Exogenous recombinant hTFF3 also directly promoted the angiogenic behavior of HUVEC. Hence, TFF3 is a potent angiogenic factor and functions as a promoter of de novo angiogenesis in mammary carcinoma, which may co-coordinate with the growth promoting and metastatic actions of TFF3 in mammary carcinoma to enhance tumor progression.

Abstract
Gastric cancer is associated with high morbidity and mortality worldwide. To reduce the socioeconomic burden related to gastric cancer, it is very important to identify and manage high risk group for gastric cancer. In this review, we describe the general risk factors for gastric cancer and define high risk group for gastric cancer. We discuss strategies for the effective management of patients for the prevention and early detection of gastric cancer. Atrophic gastritis (AG) and intestinal metaplasia (IM) are the most significant risk factors for gastric cancer. Therefore, the accurate selection of individuals with AG and IM may be a key strategy for the prevention and/or early detection of gastric cancer. Although endoscopic evaluation using enhanced technologies such as narrow band imaging-magnification, the serum pepsinogen test, Helicobacter pylori serology, and trefoil factor 3 have been evaluated, a gold standard method to accurately select individuals with AG and IM has not emerged. In terms of managing patients at high risk of gastric cancer, it remains uncertain whether H. pylori eradication reverses and/or prevents the progression of AG and IM. Although endoscopic surveillance in high risk patients is expected to be beneficial, further prospective studies in large populations are needed to determine the optimal surveillance interval.

Abstract
The new mammalian growth factor peptide family consists of three peptides, TFF1, TFF2, and TFF3, which are secreted mainly from mucous epithelia with mucus gel. The predominant secretion of trefoil factor (TFF) occurs from gastric mucosal lining, small and large intestine, oral mucosal cells, and salivary glands. Research regarding trefoil factors is an immerging aspect in the dental field. The mucosal healing and restitution function describes about its novel role in case of chronic inflammatory conditions, but its expression from different tissue at different pathological condition shows its importance in immune response. At present, TFF expression has been detected from the severe periodontal diseased tissue samples. Future research from mild to moderate chronic periodontal diseased condition should be carried out to assess the protective response of TFF in gingival tissues. In future, assessment of TFF levels and its expression in oral mucosal tissues and oral secretions, such as saliva and gingival crevicular fluid, will provide a negative biomarker for chronic periodontal diseases and a novel therapeutic agent in oral mucosal healing.

Abstract
Trefoil factor family (TFF), composed of TFF1, TFF2, and TFF3, is a cluster of secreted peptides characterized by trefoil domain (s) and C-terminal dimerization domain. TFF1, a gastric tumor suppressor, is a single trefoil peptide originally detected in breast cancer cell lines but expressed mainly in the stomach; TFF2, a candidate of gastric cancer suppressor with two trefoil domains, is abundant in the stomach and duodenal Brunner's glands; and TFF3 is another single trefoil peptide expressed throughout the intestine which can promote the development of gastric carcinoma. According to multiple studies, TFFs play a regulatory function in the mammals' digestive system, namely in mucosal protection and epithelial cell reconstruction, tumor suppression or promotion, signal transduction and the regulation of proliferation and apoptosis. Action mechanisms of TFFs remain unresolved, but the recent demonstration of a GKN (gastrokine) 2-TFF1 heterodimer implicates structural and functional interplay with gastrokines. This review aims to encapsulate the structural and biological characteristics of TFF.

[PMID: 25725142 DOI: 10.17305/bjbms.2015.251] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2014] [Revised: 12/22/2014] [Accepted: 12/22/2014] [Indexed: 01/28/2023] Open
Abstract
Trefoil factor family peptides (TFF1, TFF2, and TFF3) are predominantly found in mucous epithelia of various organs. However, they have also been reported in the nervous tissue, particularly mouse, rat, porcine, and human brain. The aim of this research was to determine the presence of TFF1 and TFF3 in the nervous system of developing mouse embryo. Mouse embryos, at the stages E15 to E17 were isolated, fixed in 4% paraformaldehyde and embedded in paraffin blocks. Sagittal 6µm sections were made, processed for immunohistochemistry, and incubated with anti-TFF1 or anti-TFF3 primary polyclonal rabbit antibodies. Labeled streptavidin-biotin method was used for TFF detection. TFF1 and 3 were found in the cytoplasm of ganglion cell somata, while TFF3 staining was also visible in the cytoplasm of neurons in different areas and nuclei of brain and medulla oblongata. Neurons in the gray matter of spinal cord were also TFF1 and TFF3 positive, and signal for both peptides was found in the choroid plexus. TFF peptides might be involved in the complex processes of nervous system development and differentiation and brain plasticity.

Abstract
The molecular biomarkers human epidermal growth factor receptor-2 (HER2) and trefoil factor 3 (TFF3) are reported to play important roles in the pathogenesis of gastric cancer (GC). In this study, we investigated the clinicopathological and prognostic significance of TFF3 and HER2 expression in GC and explored the correlation between these two biomarkers. Ninety-two patients who were diagnosed with GC were enrolled. TFF3 and HER2 expression was determined on tumor tissues. The results showed that TFF3 and HER2 were positively expressed in 42.7 and 10.9% of the cases, respectively. There were significantly higher rates of TFF3 positivity in patients with deep invasive tumors and advanced stage ones. Patients with negative TFF3 staining survived longer than those with the presence of TFF3, with 5-year overall survival (OS) rates of 57.1 ± 7.1 and 39.5 ± 7.5%, respectively (P = 0.033). However, HER2 positivity was not significantly associated with OS (P = 0.262). Multivariate analysis demonstrated TFF3 expression to be an independent indicator for short-term survival, with a hazard ratio of 2.327 (95% confidence interval (CI), 1.202-4.507, P = 0.012). There was a trend that the expression of TFF3 was more frequent in HER2 negative tumors than in HER2 positive ones (positive rates: 16.3 vs. 4.7%, P = 0.098). Patients with HER2-negative/TFF3-negative GC presented higher OS than those with other phenotypes (P = 0.009). This study suggests that TFF3 is an independent indicator for survival in GC, while HER2 is not associated with the outcome. Patients with HER2-negative/TFF3-negative GC have the best outcome.

[PMID: 25405728 DOI: 10.3892/ijo.2014.2755] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2014] [Accepted: 10/16/2014] [Indexed: 02/05/2023] Open
Abstract
The trefoil factor (TFF) family comprises three thermo-stable and protease-resistant proteins (TFF1, TFF2 and TFF3) and plays an essential role in gastrointestinal mucosa protection and regeneration, and TFFs have recently been found to be involved in the development and progression of various types of cancer. However, the clinical significance of TFFs in colorectal cancer (CRC) patients remains unclear. The present study determined the relationship between TFF expression and clinicopathological findings, as well as long-term outcome in CRC patients. The mRNA expression levels of TFFs were examined in the excised CRC specimens obtained from 154 consecutive CRC patients who underwent surgical resection between 2005 and 2007 at our institution. TFF3 expression was significantly associated with the presence of distant metastasis (p=0.017), although neither TFF1 nor TFF2 expression was associated with the clinicopathological features. Survival rate of the patients with positive TFF3 was significantly worse compared to those with negative TFF3 (p=0.011). A multivariate analysis revealed that the expression of TFF3, lymph node metastasis, and vascular invasion were independent prognostic factors for disease-specific survival. Furthermore, among 134 patients with no clinical findings of metastasis at surgery, the patients with positive TFF3 experienced recurrence within one year more frequently than those with negative TFF3 (p=0.039). In conclusion, TFF3 is not only a useful biomarker for a long-term surgical result in CRC patient, but also may be a risk factor of early recurrence.

Abstract
Although a number of studies have indicated that the positive expression of nucleophosmin (NPM) and trefoil factor 3 (TFF3) is associated with oncogenesis and poor prognosis in several tumor types, the prognostic value of the co-expression of NPM and TFF3 in gastric cancer (GC) has not been fully elucidated. Therefore, in this study, we aimed to investigate the role of NPM and TFF3 in GC and determine their prognostic value. We retrospectively reviewed 108 patients who had undergone radical gastric tumor resection. The expression of NPM and TFF3 was detected by immunohistochemistry and the association of NPM and TFF3 with clinicopathological characteristics was investigated using the Chi-square test. Furthermore, univariate and multivariate analyses were conducted to determine the prognostic value of these markers. Of the 108 samples, NPM was positive in 57 (53%) and TFF3 was positive in 54 samples (50%). The positive expression of NPM was correlated with advanced tumor stage and recurrence (P=0.0333 and P<0.0001, respectively), whereas the expression of TFF3 was associated with larger tumor size (P=0.0005), poor differentiation (P=0.0435), lymph node metastasis (P=0.0116), advanced tumor stage (P=0.0244) and recurrence (P=0.0116). The univariate analysis revealed that the expression of NPM, the expression of TFF3 and the co-expression of the two were associated with poor survival (P=0.0004, 0.0028 and 0.0020, respectively). By multivariate analysis, all three factors were identified as independent prognostic factors in postoperative GC patients (hazard ratio = 1.970, 2.021 and 2.339, respectively). In conclusion, the expression of NPM and TFF3 and, particularly, the co-expression of the two, may serve as independent prognostic factors in postoperative GC patients.

Abstract
AIM: To investigate clinical significance of expression of trefoil factor 3 (TFF3) in hepatocellular carcinoma (HCC).
METHODS: The expression of TFF3 was examined by immunohistochemical method on tissue chips containing 90 cases of HCC and 90 cases of non-tumor hepatic tissues.
RESULTS: The positive rate of TFF3 expression in HCC was significantly higher than that in non-tumor hepatic tissues (62.1% vs 33.8%, P < 0.01). TFF3 expression was significantly correlated with tumor size, TNM stage (P = 0.026 and 0.015) and relapse-free survival (P = 0.043).
CONCLUSION: TFF3 may play an important role in the development and progression of HCC, and the expression of TFF3 might be a potential marker for evaluating the prognosis of HCC.

Abstract
Objectives Trefoil factor 3 (TFF3) is a small peptide that plays an important role in mucosal protection, cell proliferation, and cell migration. The aberrant expression of TFF3 is correlated with gastrointestinal inflammation, solid tumors, and other clinical diseases. The objective of this study was to identify the distribution characteristics of serum TFF3 in common clinical diseases. Materials and Methods A large prospective randomized study of 1,072 Chinese patients was performed using an enzyme-linked immunosorbent assay (ELISA) to examine the serum TFF3 concentrations in patients with different diseases. A matched case-control study was conducted on patients with chronic kidney disease (CKD) stages 1–5. Immunohistochemistry (IHC) was performed using renal tissues to determine the relationship between the severity of CKD and the serum and urine concentrations of TFF3 peptides. Results The mean serum concentrations of TFF3 in patients with CKD, metastatic and secondary carcinoma (MC) and acute gastroenteritis (AG) (200.9 ng/ml, 95.7 ng/ml and 71.7 ng/ml, respectively) were significantly higher than those in patients with other common clinical diseases. A positive correlation tendency was observed between the serum TFF3 concentrations and the severity of CKD. The mean serum TFF3 values for CKD stages 1–5 were 23.6 ng/ml, 29.9 ng/ml, 54.9 ng/ml, 85.0 ng/ml and 176.6 ng/ml, respectively. The same trend was observed in the urine TFF3 concentrations and the CKD stages. The creatinine(Cr)-corrected concentrations of TFF3 in urine were 367.1 ng/mg·Cr, 910.6 ng/mg·Cr, 1,149.0 ng/mg·Cr, 1,610.0 ng/mg·Cr and 3,475.0 ng/mg·Cr for CKD stages 1–5, respectively. IHC revealed that TFF3 expression was concentrated in tubular epithelial cells. Conclusions The influence of kidney injuries must be fully considered when performing clinical TFF3 research. Further studies on TFF3 in CKD will contribute to our understanding of its pathological roles and mechanisms in other diseases.

Abstract
ErbB-2 gene plays an important role in carcinoma formation whose overexpression was observed in many types of tumors, including breast cancer. Dysregulation of Trefoil factor 3 (TFF3), which is thought to function in the development and progression of breast cancer, was found to be upregulated in ErbB2-overexpressing breast cancers and cells. However, a putative interaction between ErbB-2 and TFF3 in breast cancer remains unknown. To determine whether TFF3 has an important role in breast tumor, its levels were measured by immunohistochemistry in 130 cases of breast infiltrating duct carcinoma and 30 cases of normal breast tissue with a specific monoclonal antibody raised against human TFF3. Patients who were positive for ErbB-2 also had high expression levels of TFF3 (p < 0.05). Also, after infecting the SK-BR-3 cells with lentivirus-mediated ErbB2-specific shRNA (Lenti-ShERBB2), we detected the expressions of ErbB-2 and TFF3 by real-time polymerase chain reaction and Western blotting, respectively. Compared with the control groups, ErbB-2 mRNA expression was decreased in the Lenti-ShERBB2 infection group, and Western blotting indicated a concordant ErbB-2 protein reduction. On the other hand, TFF3 expression at both mRNA and protein levels was significantly downregulated by ErbB-2 silencing in SK-BR-3. These findings are a proof of the foundation for a certain relationships of ErbB-2 and TFF3, which may serve as novel therapeutic markers of ErbB2-overexpressing breast cancers in the future.

Abstract
The polymorphisms in trefoil factor (TFF) gene family that protect gastrointestinal epithelium might influence individual vulnerability to gastric cancer (GC) and atrophic gastritis. We used the Sequenom MassARRAY platform to identify the genotypes of TFF2 rs3814896 and TFF3 rs9981660 polymorphisms in 478 GC patients, 652 atrophic gastritis patients, and 724 controls. For the TFF2 rs3814896 polymorphism, in the subgroup aged ≤ 50 years, we found that AG+GG genotypes were associated with a 0.746-fold decreased risk of atrophic gastritis [p=0.023, 95% confidence interval (CI)=0.580-0.960], a 0.626-fold decreased risk of GC (p=0.005, 95% CI=0.451-0.868), and a 0.663-fold decreased risk of diffuse-type GC (p=0.034, 95% CI=0.452-0.970) compared with the common AA genotype. For the TFF3 rs9981660 polymorphism, in the male subgroup, individuals with variant AG+AA genotype were associated with a 0.761-fold decreased risk of diffuse-type GC compared with the common GG genotype (p=0.043, 95% CI=0.584-0.992). Additionally, we found that in subjects aged ≤ 50 years compared with common AA genotype, TFF2 rs3814896 AG+GG genotypes were associated with increased TFF2 mRNA levels in the total gastric cancer specimens and in the diffuse-type gastric cancer specimens; and in males aged ≤ 50 years compared with common GG genotype, TFF3 rs9981660 AA+AG genotypes were associated with TFF3 mRNA levels in diffuse-type gastric cancer tissues and their corresponding non-cancerous tissues. To our knowledge, this is the first report of an association between the TFF2 rs3814896 AG+GG genotypes and decreased risks of GC, diffuse-type GC, and atrophic gastritis in younger people aged ≤ 50 years, and an association between TFF3 rs9981660 AG+AA genotype and decreased risk of diffuse-type GC in men. Moreover, we found that TFF2 rs3814896 AG+GG genotypes in people aged ≤ 50 years and TFF3 rs9981660 AG+AA genotypes in younger males with diffuse-type GC were associated with higher levels of TFF2 and TFF3 mRNA respectively.

Abstract
BACKGROUND AND AIM Emerging data indicate that serum trefoil factors (TFFs), especially TFF3, could be potential biomarkers for gastric cancer risk. We aimed to evaluate the influence of Helicobacter pylori (H. pylori) status and eradication on serum TFFs and the pepsinogen test. METHODS Healthy individuals who underwent a thorough medical checkup were enrolled in study 1, and gastric ulcer patients who undertook H. pylori eradication therapy were enrolled in studies 2 and 3. Serum levels of the TFFs (TFF1, TFF2 and TFF3), H. pylori antibody and pepsinogen test were examined in all studies. In study 3, TFF expressions in biopsy samples of the gastric mucosa were additionally examined before and 2 months after eradication. RESULTS In 1,260 healthy individuals enrolled in study 1, serum TFF1 and TFF2 levels were markedly different between H. pylori antibody-positive and -negative participants (P < 0.0001). Differences in serum TFF3 levels between H. pylori antibody-positive (5.85 ± 3.93 ng/ml) and -negative subjects (5.27 ± 2.38 ng/ml) were statistically significant (P = 0.002) but small in absolute value. In 178 gastric ulcer patients enrolled in study 2, serum TFF1, TFF2 and positive rates of the pepsinogen test significantly decreased 2 months after H. pylori eradication therapy (P < 0.001). In contrast, serum TFF3 levels and positive rates of high TFF3 levels (≥7 ng/ml) did not significantly change with H. pylori-eradication until 5 years after eradication. In 18 gastric ulcer patients (study 3), TFF1 and TFF2 were mainly expressed in the foveolar epithelium, and TFF2 was additionally expressed in the pyloric glands. These expressions significantly decreased with H. pylori eradication. TFF3s were scarcely expressed in the gastric mucosa except in goblet cells of intestinal metaplasia, which did not change with H. pylori eradication. CONCLUSION In serum TFFs and pepsinogen tests, only serum TFF3s were not significantly affected by H. pylori eradication, suggesting that serum TFF3 could be a stable biomarker of gastric cancer risk even after H.pylori eradication in contrast with the pepsinogen test.

Gynecol Oncol 2013; 130:174-80.

Abstract
OBJECTIVES TFF3 has been found to be up-regulated at the gene and protein levels in endometrioid adenocarcinoma (EAC) when compared to uterine serous carcinoma (USC) and normal endometrium. In addition, TFF3 has been proven to be an estrogen-responsive gene and its expression level positively correlated to estrogen-receptor (ER) status in breast cancer cell culture. The aims of this study are to determine the expression and the prognostic value of TFF3 in a large series of human endometrial cancer and its relation with ER. METHODS We evaluated 328 endometrial carcinomas using TFF3 and ER antibody on paraffin-embedded tissue. 74% were type I (EAC), and 26% were type II (USC, CCC and carcinosarcoma). RESULTS In type I carcinomas, TFF3(+) expression was associated with no lympho-vascular invasion (p=0.0131), disease status (p=0.0132), recurrence-free survival (p=0.0424) and overall survival (p=0.0018). There was a positive association between TFF3 and ER (p<.0001). The combination of TFF3(+)/ER(+) was associated with low FIGO grade (p=.0122), early FIGO stage (p=.0062), absence of recurrence (p=.0037), absence of LVI (p=.0011), no lymph node involvement (p=.0116) and disease status (p=.0107). TFF3 appeared to be an independent prognostic marker in predicting recurrences (p=.046). In type II carcinomas, TFF3 failed to have a prognostic value. CONCLUSION 1-TFF3 seems to be a novel pathway in the pathogenesis of type I endometrial carcinomas. 2-The strong association of TFF3 and ER in the estrogen-dependent endometrioid carcinoma could explain the reason for its frequent expression by this tumor type. 3-TFF3(+) seems to forecast a good prognosis in type I endometrial carcinomas. Based on our data, TFF3 expression in endometrial cancer deserves further investigation.

Abstract
OBJECTIVES The trefoil factor family (TFF) is composed of three thermostable, and protease-resistant proteins, named TFF1, TFF2 and TFF3, and plays a role in gastrointestinal mucosal defence and repair. Recently, TFFs have been found to be related to the development of various types of cancer. This study assessed the relationship between the expression of TFF1 and TFF3 and the clinicopathological parameters in gastric carcinoma (GC). MATERIALS AND METHODS The expression of TFF1 and TFF3 was analyzed by immunohistochemistry in 292 GCs and 20 normal gastric tissues. RESULTS All normal gastric tissues expressed TFF1, but 53.8% of GCs showed reduced TFF1 expression. However, TFF3 was not detected in normal gastric tissues and 44.2% of GCs showed a high level of expression. Highly expressed TFF3 was significantly correlated with lymph node metastasis, lymphatic invasion, vein invasion, and advanced stage. The overall survival was shorter in patients with high expression of TFF3 than in those with low expression of TFF3 in 292 GCs and in 125 early GCs (EGCs). Moreover, in patients with EGCs, high expression of TFF3, associated with reduced expression of TFF1, was determined as an independent poor prognostic marker. CONCLUSIONS Reduced expression of TFF1 and increased expression of TFF3 may play a role in the carcinogenesis of gastric cancer. Furthermore, high expression of TFF3 with reduced expression of TFF1 may be a marker of poor prognosis for patients with EGC.

Abstract
Trefoil factor 3 (TFF3) and survivin with functions of inhibiting apoptosis are involved in the gastric cancer by overexpression. The purpose of this study is to examine the expression of TFF3 and survivin in patients' tissue samples with gastric cancer and analyze the relationship between the protein expression and the different clinical records. By studying the expressions of TFF3 and survivin in gastric cancer through immunohistochemical staining and examining the survival rate via Kaplan-Meier analysis for gastric cancer patients, we found that the TFF3 and survivin positive expressions have a significant relationship with the lower survival rate comparing to that of negative expressions in the analyzed patients (P < 0.05). And moreover, patients with double positive TFF3 and survivin expressions have the lowest survival rate. TFF3 or survivin positive expression correlates with the lymph node metastasis, metastasis, and TNM stages of gastric cancer. Survival analysis indicates that survival rate has a close relationship with the age, tumor histology, tumor differentiation, degree of infiltration, lymph node metastasis, distant metastasis, and TNM stages (P < 0.01). Our data suggest that TFF3 and survivin expressions play a vital role in gastric cancer development, and these two proteins are important markers for prognosis in gastric cancer. Patients with gastric cancer can increase the survival rate through an earlier diagnosis and appropriate treatment.

Abstract
BACKGROUND The early diagnosis of biliary tract cancer (BTC) remains challenging, and there are few effective therapies. This study investigated whether the M2 isotype of pyruvate kinase (M2-PK), which serves as the key regulator of cellular energy metabolism in proliferating cells, could play a role in the diagnosis and therapy of BTC. METHODS Plasma and bile M2-PK concentrations were measured by enzyme-linked immunosorbent assay in 88 patients with BTC, 79 with benign biliary diseases, and 17 healthy controls. M2-PK expression was assayed in a BTC tissue array by immunohistochemistry. The role of M2-PK in tumor growth, invasion, and angiogenesis was evaluated in BTC cell lines by retrovirus-mediated M2-PK transfection and short hairpin RNA silencing techniques. RESULTS Sensitivity (90.3%) and specificity (84.3%) of bile M2-PK for malignancy were significantly higher than those for plasma M2-PK and serum carbohydrate antigen 19-9. M2-PK expression was specific for cancer cells and correlated with microvessel density. M2-PK positivity was a significant independent prognostic factor by multivariable analysis. Transfection of M2-PK in a negatively expressed cell line (HuCCT-1 cells) increased cell invasion, whereas silencing in an M2-PK-positive cell line (TFK cells) decreased tumor nodule formation and cellular invasion. A significant increase in endothelial tube formation was noted when supernatants from M2-PK-transfected cells were added to an in vitro angiogenesis assay, whereas supernatants from silenced cells negated endothelial tube formation. CONCLUSIONS Bile M2-PK is a novel tumor marker for BTC and correlates with tumor aggressiveness and poor outcome. Short hairpin RNA-mediated inhibition of M2-PK indicates the potential of M2-PK as a therapeutic target.

Abstract
BACKGROUND Ongoing Helicobacter pylori (HP) infection triggers a chronic active gastritis. Eradicating HP reduces gastric inflammation, but does not eliminate it. We sought to characterize this persistent gastritis, and demonstrate the persistence of HP-specific Th17 responses in individuals previously infected with HP but who no longer had evidence of ongoing infection. METHODOLOGY/PRINCIPAL FINDINGS Study subjects were divided into 3 groups 55 individuals had active HP infection (group A), 41 were diagnosed with previous HP infection (group P), and 59 were naïve to HP (group N). Blood and gastric tissue were obtained with written informed consent from all subjects, and immune responses were evaluated using flow cytometry, semi-quantitative real time PCR, immunofluorescent staining, ELISA, and multiplex cytometric bead array for cytokine quantification. Elevated IL-17A responses were observed in patients from group A compared to group N. Interestingly, IL-17A responses remained persistently elevated in the blood and gastric mucosa of individuals from group P, despite the absence of ongoing HP infection. Using purified CD4(+) T cells as effectors and antibodies that blocked antigen presentation by MHC Class II, we showed that these persistent IL-17A responses were mediated primarily by HP-specific Th17 cells, rather than other immune cells that have also been described to secrete IL-17A. Gastric mucosal IL-1β levels were also persistently elevated in group P, and neutralisation of IL-1β reduced the HP-specific IL-17A response of purified CD4(+) T cells to autologous HP-pulsed antigen presenting cells in vitro, suggesting a functional association between IL-1β and the persistent Th17 response in group P patients. CONCLUSIONS/SIGNIFICANCE Despite lack of ongoing HP infection, HP-specific Th17 cells persist in the blood and gastric mucosa of individuals with past HP infection. We speculate that this persistent inflammation might contribute to gastric mucosal pathology, for example, persistent increased gastric cancer risk despite eradication of HP.

Abstract
Gastric cancer is one of the leading causes of cancer mortality and its malignancy, resulting from disseminated cancer cells of diffuse type, is clinically manifested as metastases to the liver and peritoneum. The aim of the present study was to identify putative tumor metastasis-associated genes in human gastric cancer cells of diffuse type. An MKN45 cell line constitutively expressing green fluorescent protein (MKN45-GFP) was established and selected using the Transwell® system for invasive sublines MKN45-GFP-4, MKN45-GFP-10 and MKN45-GFP-12. MKN45-GFP-10 and MKN45-GFP-12 are highly invasive compared to the others. The mRNA levels were measured with cDNA microarrays and correlated with their invasion abilities in these sublines. Many of the genes identified with a positive or negative correlation are associated with angiogenesis, cell cycle, cytoskeleton and cell motility, protease and cell adhesion, as well as cellular signal transduction. In particular, novel genes without known functions were also noted. RT-PCR and western blot analyses were applied to verify the expression of selective genes. Following orthotopical intraperitoneal implantation, MKN45-GFP-12 demonstrated significantly higher in vivo tumor malignancies than parental MKN45-GFP in ascites induction and liver -invasion in mice. We have identified putative gastric tumor metastasis-associated, as well as novel genes. These genes and their protein products are to be further explored for their functional roles associated with tumor metastasis. The molecular profiles of these identified genes, gene transcripts and proteins in the patient specimens are likely to be useful biomarkers for diagnostic, therapeutic and/or prognostics. Most importantly, they may be used as molecular targets for the discovery of antitumor drugs against human gastric cancer metastasis.

TFF3 is a normal breast epithelial protein and is associated with differentiated phenotype in early breast cancer but predisposes to invasion and metastasis in advanced disease. THE AMERICAN JOURNAL OF PATHOLOGY 2012; 180:904-916. [PMID: 22341453 DOI: 10.1016/j.ajpath.2011.11.022] [Citation(s) in RCA: 57] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/04/2011] [Revised: 10/12/2011] [Accepted: 11/17/2011] [Indexed: 11/17/2022]
Abstract
The trefoil protein TFF3 stimulates invasion and angiogenesis in vitro. To determine whether it has a role in breast tumor metastasis and angiogenesis, its levels were measured by immunohistochemistry in breast tissue with a specific monoclonal antibody raised against human TFF3. TFF3 is expressed in normal breast lobules and ducts, at higher levels in areas of fibrocystic change and papillomas, in all benign breast disease lesions, and in 89% of in situ and in 83% of invasive carcinomas. In well-differentiated tumor cells, TFF3 is concentrated at the luminal edge, whereas in poorly differentiated cells polarity is inverted and expression is directed toward the stroma. Expression was high in well-differentiated tumors and was associated significantly with low histological grade and with estrogen and progesterone receptor expression, accordant with induction of TFF3 mRNA by estrogen in breast cancer cells. Paradoxically, TFF3 expression was associated with muscle, neural, and lymphovascular invasion and the presence and number of involved lymph nodes, and it was an independent predictive marker of lymphovascular invasion and lymph node involvement. Consistent with an angiogenic function, TFF3 expression correlated strongly with microvessel density evaluated with CD31 and CD34. In conclusion, TFF3 is expressed in both the normal and diseased breast. Although associated with features of good prognosis, its profile of expression in invasive cancer is consistent with a role in breast tumor progression and tumor cell dissemination.

Abstract
Lung cancer is the most common cause of cancer-related deaths in the world. The trefoil factor (TFF) family is composed of three thermostable, and protease-resistant proteins, named TFF1, TFF2 and TFF3. TFF protein levels have been found to be related to the development of various types of cancer. However, it is still unclear whether TFF proteins are differentially expressed in the serum of different histological subtypes of lung cancer compared to healthy individuals. In this study, we investigated the levels of TFF proteins in serum and lung tissues of 130 lung cancer patients (58 squamous cell lung carcinoma cases, 43 adenocarcinoma cases and 29 SCLC cases) and 60 healthy individuals. It was found that TFF1 and TFF2 have similar or slightly higher levels in these three subtypes of lung cancer compared to healthy individuals, while TFF3 levels were significantly higher in the examined lung cancer cases compared to healthy individuals. Immunoblot analyses of TFF1, TFF2 and TFF3 indicated that lung cancer tissues and lung cancer cell lines have a higher expression of the TFF3 protein, but not of TFF1 or TFF2 proteins, compared to tissues from healthy individuals or from the normal cell line. Quantitative RT-PCR analysis indicated higher levels of TFF3, but not TFF1 and TFF2, transcripts in lung cancer tissues or cell lines. These results show increased TFF3 levels in serum and lung tissues, suggesting that TFF3 may serve as a promising, easily detected biomarker of lung cancer.

Abstract
Trefoil factor 2 (TFF2) is a member of trefoil factor family found to be overexpressed in many cancers including cholangiocarcinoma (CCA). The majority of studies have focused on wild-type TFF2 (wtTFF2) expression, but information regarding alternative splicing variants of TFF2 mRNA has not been reported. In this study, we aimed to identify and quantify a novel TFF2 splice variant in cholangiocarcinoma (CCA). Seventy-eight tumors and 15 normal adjacent tissues were quantified for the expression of the TFF2 splice variant relative to wild-type (wt) TFF2 mRNA using quantitative reverse transcriptase polymerase chain reaction (QRT-PCR). The ratio of TFF2 splice variant against wtTFF2 was analyzed for associations with clinical parameters. We found a novel TFF2 splice variant, exon 2 skipping (∆EX2TFF2), resulting in a stop codon (TAG) at exon 1. The ∆EX2TFF2/wtTFF2 ratio in tumors was significantly higher than in normal tissue (P<0.01). Interestingly, high ∆EX2TFF2/wtTFF2 ratio was significantly associated with good prognosis compared with low ratio (P=0.017). In contrast, the presence of wtTFF2 protein was associated with poor survival of CCA patients (P=0.034). This is the first report of a trefoil factor splice variant and its potential application as a prognostic biomarker in CCA.

Abstract
BACKGROUND A valid biomarker for predicting the presence of gastric cancer may contribute to reducing deaths from this disease. Although pepsinogen (PG) testing has been introduced as a predictor, its predictive power is not satisfactory. We examined whether serum trefoil factor (TFF) could be a non-endoscopic predictor of the presence of gastric cancer. METHODS Gastric cancer patients who underwent preoperative endoscopy were sequentially recruited. Individuals who underwent a thorough medical checkup were enrolled as non-cancer controls. Serum levels of TFF1, TFF2, TFF3, Helicobacter pylori antibody, PG I, and PG II were examined. RESULTS We studied 192 gastric cancer patients aged 64.3 ± 9.7 years and 1254 non-cancer controls aged 52.3 ± 12.4 years. In the age/gender-matched analysis (187 cases and 561 controls), significant relationships were demonstrated between gastric cancer presence and TFF3 (P < 0.0001), the PGI/II ratio (P < 0.0001), H. pylori antibody (P = 0.001), TFF1 (P = 0.012), and TFF2 (P = 0.020). The area under the receiver-operating characteristic curve for predicting gastric cancer presence was comparably high for all factors (0.893) and for the combination of TFF3 and the PG test (0.883), but was significantly (P < 0.0001) lower for the PG test alone (0.823). A positive PG test showed a sensitivity of 67% and specificity of 82%, whereas a combination of TFF3 and PG testing showed a sensitivity of 80% and specificity of 80% in predicting the presence of gastric cancer. CONCLUSION The combination of serum TFF3 and PG testing might be a valid non-endoscopic biomarker for predicting the presence of gastric cancer.

Abstract
OBJECTIVE To obtain new insights into aetiological backgrounds, and to search for diagnostic biomarkers by assessing the difference in urinary proteins between cats with spontaneous feline idiopathic cystitis (FIC) and healthy controls. MATERIALS AND METHODS Urine supernatants of 18 cats with FIC and 18 healthy control cats, and bladder biopsies of two FIC diseased cats and four healthy controls were included in the study. The Bradford method was used to determine protein quantity in urine supernatants. Urine was separated by two-dimensional (2-D) gel electrophoresis. Selected protein spots were excised from two-dimensional gels and analysed with tandem mass spectrometry. Validation of Trefoil factor 2 expression was realized with Western blot and immunohistochemistry. Western blot signal intensities were quantified with image quant software. RESULTS Eleven differentially expressed protein spots were identified between the 2-D gels of cats with FIC and control cats. Ten spots (only visible in the FIC gel) were identified as albumin and one spot (only visible in the control gel) was identified as Trefoil factor 2.Using quantification of Western blot signal intensities and immunohistochemistry a decrease in Trefoil factor 2 (TFF2) in cats with FIC could be revealed for the first time. CONCLUSION Deficiency in TFF2 possibly leads to impaired repairing abilities and immune response of the urothelium. The result could be a greater susceptibility to injury, inflammation and relapse. Therefore TFF2 deficiency might be an important event in FIC pathogenesis. Detection of a decrease in urinary TFF2 could serve as diagnostic biomarker, facilitating diagnosis. As FIC can serve as an animal model for human painful bladder syndrome/interstitial cystitis, the findings of this study might also be valuable for interstitial cystitis research and should be further investigated.

Abstract
We report herein that trefoil factor 3 (TFF3) is oncogenic and mediates anti-estrogen resistance in human mammary carcinoma. Forced expression of TFF3 in mammary carcinoma cells increased cell proliferation and survival, enhanced anchorage-independent growth, and promoted migration and invasion. Moreover, forced expression of TFF3 increased tumor size in xenograft models. Conversely, depletion of endogenous TFF3 with small interfering RNA (siRNA) decreased the oncogenicity and invasiveness of mammary carcinoma cells. Neutralization of secreted TFF3 by antibody promoted apoptosis, decreased cell growth in vitro, and arrested mammary carcinoma xenograft growth. TFF3 expression was significantly correlated to decreased survival of estrogen receptor (ER)-positive breast cancer patients treated with tamoxifen. Forced expression of TFF3 in mammary carcinoma cells increased ER transcriptional activity, promoted estrogen-independent growth, and produced resistance to tamoxifen and fulvestrant in vitro and to tamoxifen in xenograft models. siRNA-mediated depletion or antibody inhibition of TFF3 significantly enhanced the efficacy of antiestrogens. Increased TFF3 expression was observed in tamoxifen-resistant (TAMR) cells and antibody inhibition of TFF3 in TAMR cells improved tamoxifen sensitivity. Functional antagonism of TFF3 therefore warrants consideration as a novel therapeutic strategy for mammary carcinoma.

Abstract
Trefoil factors (TFF), expressed physiologically in the secretory cells of gastrointestinal mucosa and other mucosal tissues, compose a unique peptide family with important biologic functions. Aberrant expression and/or continued secretion of TFF might exist concurrently with the processes of digestive system inflammation, tumor or other related pathological changes. Previous pathological studies have shown that the abnormal expression of TFF is associated with the prognosis of digestive system diseases. The results obtained from gene expression profiling, tumor secretomics and bioinformatic analysis have positively confirmed that clinical detection of TFF peptides or mRNAs has an excellent diagnostic performance to detect digestive system diseases, especially for the monitoring of recurrence or metastasis of tumors and for the estimation of therapeutic efficacy and prognosis. Therefore, TFF is a potential biomarker for diagnosis, treatment and prognosis of digestive system diseases.

Abstract
PURPOSE This study aimed to identify novel hypoxia-inducible and prognostic markers in vivo from hypoxic tumor cells. EXPERIMENTAL DESIGN Using carbonic anhydrase 9 and CD34 as a guide for hypoxic tumor cells, laser capture microdissection was used to isolate colorectal cancer (CRC) liver metastases. The samples were analyzed by microarray analysis, in parallel with five CRC cell lines cultured under hypoxic conditions. To evaluate the prognostic impact of the expression of certain genes, samples from a total of 356 CRC patients were analyzed by microarray or quantitative reverse transcription-PCR. In vitro mechanistic studies and in vivo therapeutic experiments were also done about a histone H3 Lys(9) demethylase, Jumonji domain containing 1A (JMJD1A). RESULTS Several candidate genes were identified by microarray analysis of liver metastases and culturing of CRC cells under hypoxic conditions. Among them, we found that JMJD1A was a novel independent prognostic factor for CRC (P = 0.013). In vitro assays revealed that loss of JMJD1A by small interfering RNA treatment was associated with a reduction of proliferative activity and decrease in invasion of CRC cell lines. Furthermore, treatment with an adenovirus system for antisense JMJD1A construct displayed prominent therapeutic effects when injected into established tumor xenografts of the CRC cell lines HCT116 and DLD1. CONCLUSIONS JMJD1A is a useful biomarker for hypoxic tumor cells and a prognostic marker that could be a promising therapeutic target against CRC.

Abstract
Lymph node metastasis is the major concern that causes death in colorectal cancers. However, biomarkers for cancer metastasis are still lacking. In this study, we applied an LC-MS/MS-based label-free quantitative proteomics approach to compare the differential secretome of a primary cell line SW480 and its lymph node metastatic cell line SW620 from the same colorectal cancer patient. We identified a total of 910 proteins from the conditioned media and 145 differential proteins between SW480 and SW620 (>1.5-fold change). The differential expression pattern of 6 candidate proteins was validated by Western blot analysis. Among them, trefoil factor 3 and growth/differentiation factor 15, two up-regulated proteins in SW620, were further analyzed in a large cohort of clinical tissue and serum samples. Sandwich ELISA assay showed that the serum levels of both proteins were significantly higher in lymph node metastatic colorectal cancers. Receiver operating characteristic curve analysis confirmed that serum trefoil factor 3 and growth/differentiation factor 15 could provide a discriminatory diagnostic test for predicting colorectal cancer metastasis. Immunohistochemical analysis also showed that the overexpression of trefoil factor 3 or growth/differentiation factor 15 in colorectal cancer was associated with lymph node metastatic behavior. This study showed an accurate, sensitive, and robust label-free quantitation approach for differential analysis of cancer secretome. The comparison of the cancer secretome in vitro is a feasible strategy to obtain valuable biomarkers for potential clinical application. Both trefoil factor 3 and growth/differentiation factor 15 could serve as potential biomarkers for the prediction of colorectal cancer metastasis.

Abstract
AIM: To investigate the expression of trefoil factor 3 (TFF3) in gastric carcinoma, precancerous lesions, gastric adenoma and explore its correlation with microvessel density (MVD) in gastric carcinogenesis.
METHODS: The expression of TFF3 was detected by the immunohistochemical PV-6000 method in 120 gastric mucosal specimens, including 20 cases of normal gastric mucosa (NGM), 20 cases of gastric adenoma (GA), 20 cases of chronic atrophic gastritis with intestinal metaplasia (IM), 20 cases of dysplasia (DYS), and 40 cases of gastric carcinoma (GC). MVD was examined by immunohistochemistry using anti-CD34 antibody.
RESULTS: The positive rates of TFF3 expression were significantly higher in GA, IM, DYS and GC than in NGM (50.0%, 65.0%, 70.0% and 57.5% vs 5.0%, respectively; all P < 0.01). MVD was significantly higher in GC than in NGM, GA, IM and DYS (30.65 ± 6.04 vs 14.87 ± 3.06, 22.33 ± 3.78, 23.16 ± 3.20 and 25.22 ± 4.66, respectively; all P < 0.01). MVD was also significantly higher in GA, IM, DYS and GC than in NGM (all P < 0.01). TFF3 expression and MVD were correlated with lymph node metastasis and tumor stage in GC (all P < 0.05). MVD was also correlated with depth of invasion in GC (P < 0.05). MVD in specimens showing positive expression of TFF3 was higher than that in specimens showing negative expression (34.53 ± 4.45 vs 25.39 ± 3.25, P < 0.01).
CONCLUSION: TFF3 may be involved in an early event in gastric carcinogenesis and play an important role in gastric carcinogenesis. Detection of TFF3 expression may be of great significance for early diagnosis and prediction of metastasis in gastric carcinoma.

Abstract
BACKGROUND Several gene expression signatures have been reported to predict patient survival of gastric cancer after surgical resection. However, the prognostic gene lists have overlapped poorly until now. This study conducted an analysis to characterize gene expression profile and developed a survival prediction model. METHODS The gene expression profile was evaluated in fresh frozen tumor tissue obtained from 48 patients with primary gastric cancer. We measured 84 representative genes involved in transformation and tumorigenesis using quantitative reverse transcription polymerase chain reaction (qRT-PCR) and related the results to overall survival. RESULTS In a univariate analysis, 84 genes were ranked on their ability to predict survival, of which nine genes were the strongest predictor (P<0.05). They were PLAU, MAP2K1, THBS1, TWIST1, ITGB5, NME4, ANGPT2, platelet-derived growth factor B (PDGFB), ITGB1. Then, we did a multivariate analysis to further select four genes (ITGB1, PDGFB, THBS1, TWIST1) from the above nine genes for the construction of biomathematics model, which was independent of age, gender, TNM stage and other variables. This model could correctly clarify gastric patients into the high-risk group, median-risk group and low-risk group, as well as predict their survival. CONCLUSIONS Measurement of the expression of four genes is probable to predict surgery-related survival. This model may be test further for its potential to improve the selection of the resected gastric cancer patients in adjuvant chemotherapy.

Abstract
Trefoil factor family (TFF) consists of three members, including TFF1, TFF2 and TFF3. TFF has such functions as maintaining gut mucosal integrity, promoting epithelial cell restitution, as well as cell signal transduction, modulating apoptosis and enhancing invasion. Therefore, TFF plays crucial roles in the process of inflammation and tumorigenesis. Researches recently have indicated that TFF3 plays an important role in gastric cancer, especially in intestinal gastric carcinoma.
