BACKGROUND: There remains a great need for effective therapies for cervical cancers, the majority of which are aggressive leaving patients with poor prognosis. METHODS AND RESULTS: Here, we identify a novel candidate therapeutic target, trefoil factor 3 (TFF3) which overexpressed in cervical cancer cells and was associated with reduced postoperative survival. Functional studies demonstrated that TFF3 overexpression promoted the proliferation and invasion of cervical cancer cells, and inhibited the apoptosis by inducing the mRNA changes in SiHa and Hela cell lines...

BACKGROUND: Increasing evidence suggests that depot medroxyprogesterone acetate (DMPA) and intravaginal practices may be associated with an increased risk of HIV infection; however the mechanisms are not fully understood. This study evaluated the effect of DMPA and intravaginal practices on the genital mucosal proteome and microbiome to gain mechanistic insights. METHODS: Cervicovaginal secretions from 86 Kenyan women, including self-reported DMPA (n=23) and non-hormonal contraceptive users (n=63), and women who practice vaginal drying (n=46) were analyzed using tandem-mass spectrometry in a cross sectional manner...

The success of cisplatin-containing regimens to treat solid tumors is limited, in part, by nephrotoxicity. In rodents, several urinary proteins have emerged as more sensitive indicators of cisplatin-induced kidney injury. We sought to characterize time-dependent changes in the urinary concentrations of 12 proteins including KIM-1, calbindin, β2M, and TFF3 after cisplatin therapy. Urine was collected at baseline, 3 (range: 2-5), and 10 (range: 9-11) days from 57 patients with solid tumors receiving outpatient cisplatin therapy (≥ 25 mg/m(2) )...

INTRODUCTION: Despite extensive research, anastomotic leakage (AL) remains one of the most dreaded complications after colorectal surgery. Since butyrate enemas are known to enhance anastomotic healing, several administration routes have been explored in this study. METHODS: Three intraluminal approaches involving butyrate were investigated: (1) butyrin-elucidating patch, (2) a single injection of hyaluronan-butyrate (HA-But) prior to construction of the proximal anastomosis and (3) rectal hyaluronan-butyrate (HA-But) enemas designed for distal anastomoses...

BACKGROUND: Strengthening of intestinal tight junctions provides an effective barrier from the external environment. Goblet cell-derived trefoil factor 3 (TFF3) increases transepithelial resistance by upregulating the expression of tight junction proteins. Oxyresveratrol (OXY) is a hydroxyl-substituted stilbene found in the roots, leaves, stems, and fruit of many plants and known to have various biological activities. In this study, we investigated the strengthening effect of OXY on intestinal tight junctions through stimulation of TFF production in goblet cells...

Barrett's metaplasia is the only known morphological precursor to oesophageal adenocarcinoma and is characterized by replacement of stratified squamous epithelium by columnar epithelium. The cell of origin is uncertain and the molecular mechanisms responsible for the change in cellular phenotype are poorly understood. We therefore explored the role of two transcription factors, Cdx2 and HNF4α in the conversion using primary organ cultures. Biopsy samples from cases of human Barrett's metaplasia were analysed for the presence of CDX2 and HNF4α...

BACKGROUND/AIMS: The trefoil factor family (TFF) peptide TFF1 is a typical secretory product of the gastric mucosa and a very low level of expression occurs in nearly all regions of the murine brain. TFF1 possesses a lectin activity and binding to a plethora of transmembrane glycoproteins could explain the diverse biological effects of TFF1 (e.g., anti-apoptotic effect). It was the aim to test whether TFF expression is changed during neuroinflammation. METHODS: Expression profiling was performed using semi-quantitative RT-PCR analyses in two murine models of neuroinflammation, i...

Small intestinal neuroendocrine tumors (SI-NETs) are amine- and peptide producing neoplasms. Most patients display metastases at the time of diagnosis, they have an unpredictable individual disease course and the tumors are often therapy resistant. Chromogranin A (CgA) and 5-hydroxyindoleacetic acid (5-HIAA) are the clinically most used biomarkers today, but there is a great need for novel diagnostic and prognostic biomarkers and new therapeutic targets. Sixty-nine biomarkers were screened in serum from 23 SI-NET patients and 23 healthy controls using multiplex PLA (proximity ligation assay)...

Temporal and spatial regulation of genes mediated by tissue-specific promoters and conditional gene expression systems provide a powerful tool to study gene function in health, disease, and during development. Although transgenic mice expressing the Cre recombinase in the gastric epithelium have been reported, there is a lack of models that allow inducible and reversible gene modification in the stomach. Here, we exploited the gastrointestinal epithelium-specific expression pattern of the three trefoil factor (Tff) genes and bacterial artificial chromosome transgenesis to generate a novel mouse strain that expresses the CreERT2 recombinase and the reverse tetracycline transactivator (rtTA)...

INTRODUCTION: The viscoelastic properties of the cervical mucus plug are considered essential for the occlusion of the cervical canal and thereby for protection against ascending infections during pregnancy. Factors controlling this property are virtually unknown. This study explores a possible role of trefoil factor peptides 1, 2 and 3 (TFF1-3); peptides believed to influence mucus viscosity. MATERIAL AND METHODS: The study is based on spontaneously shed cervical mucus plugs from 14 women in active labor...

BACKGROUND: Acute kidney injury (AKI) caused by drug and toxicant ingestion is a serious clinical condition associated with high mortality rates. We currently lack detailed knowledge of the underlying molecular mechanisms and biological networks associated with AKI. In this study, we carried out gene co-expression analyses using DrugMatrix-a large toxicogenomics database with gene expression data from rats exposed to diverse chemicals-and identified gene modules associated with kidney injury to probe the molecular-level details of this disease...

The role of trefoil factor 3 (intestinal) (TFF3) has been analyzed in numerous cancers, such as breast and gastrointestinal cancer, and has been associated with poor prognosis. However, the role of TFF3 in ovarian cancers is not clear. Expression analysis of TFF3 in 91 ovarian cancer patients was performed by immunohistochemistry of primary paraffin-embedded tumor samples. The results were scored according to staining intensity and percentage of positive tumor cells resulting in an immune-reactive score (IRS) of 0-12...

Trefoil factor family (TFF) peptides have been shown to effect cell proliferation, apoptosis, migration and invasion of normal cells and various cancer cell lines. In the literature TFF peptides are controversially discussed as tumor suppressors and potential tumor progression factors. In the study presented, we investigated the effect of TFF3 overexpression on growth, viability, migration and tumorigenicity of the human retinoblastoma cell lines Y-79, WERI-Rb1, RBL-13 and RBL-15. As revealed by WST-1 and TUNEL assays as well as DAPI and BrdU cell counts, recombinant human TFF3 significantly lowers retinoblastoma cell viability and increases apoptosis levels...

STUDY QUESTION: Does the changing molecular profile of the endometrium during menstruation correlate with the histological profile of menstruation. SUMMARY ANSWER: We identified several genes not previously associated with menstruation; on Day 2 of menstruation (early-menstruation), processes related to inflammation are predominantly up-regulated and on Day 4 (late-menstruation), the endometrium is predominantly repairing and regenerating. WHAT IS KNOWN ALREADY: Menstruation is induced by progesterone withdrawal at the end of the menstrual cycle and involves endometrial tissue breakdown, regeneration and repair...

Trefoil factors are effector molecules in gastrointestinal tract physiology. Each one improves healing of the gastrointestinal tract. Trefoil factors may be grouped into three classes: the gastric peptides (TFF1), spasmolytic peptide (TFF2) and intestinal trefoil factor (TFF3). Significant amounts of TFF3 are present in human breast milk. Previously, we have reported that trefoil factor 3 isolated from human breast milk produces down regulation of cytokines and promotes human beta defensins expression in intestinal epithelial cells...

Influenza A viruses (IAV) mutate rapidly and cause seasonal epidemics and occasional pandemics, which result in substantial number of patient visits to the doctors and even hospitalizations. We aimed here to identify inflammatory proteins, which levels correlated to clinical severity of the disease. For this we analysed 102 cytokines and growth factors in human nasopharyngeal aspirate (NPA) samples of 27 hospitalized and 27 outpatients diagnosed with influenza A(H1N1)pdm09 virus infection. We found that the relative levels of monocyte differentiation antigen CD14, lipocalin-2 (LCN2), C-C-motif chemokine 20 (CCL20), CD147, urokinase plasminogen activator surface receptor (uPAR), pro-epidermal growth factor (EGF), trefoil factor 3 (TFF3), and macrophage migration inhibitory factor (MIF) were significantly lower (p<0...

This study analyzed whether trefoil factor 3 (TFF3) is locally elevated and correlated with common biomarkers and inflammatory processes in endometriosis. Peritoneal fluid (PF) was obtained from 50 women and serum from 124 women with or without endometriosis. Experimental endometriosis was induced in female C57BL/6 mice by syngeneic transplantation of uterine tissue to the abdominal wall. Levels of TFF3 in PF of women with endometriosis were significantly increased (P < .05) and correlated with local levels of known biomarkers for endometriosis: cancer antigen (CA) 125, CA-19-9, interleukin 8, monocyte chemotactic protein 1, and matrix metalloproteinase 7...
