    ABSTRACT: Endometriosis is a benign gynecological disease affecting approximately 10-15% of women of reproductive age and 25-50% of all infertile women. It is characterized by the presence of glands and/or endometrial stroma outside the uterine cavity. Angiogenesis is a crucial process for the development and maintenance of endometriotic lesions. The Wnt/β-catenin pathway is a major promoter of angiogenesis in both physiological and pathological conditions. In the present study, we evaluated the expression of molecules related to the Wnt/β-catenin pathway in a rat model of peritoneal endometriosis. mRNA analyses showed significantly increased expression of Wnt4 and Wnt7b and decreased expression of Gsk3beta and E-cadherin in endometriotic lesions. However, there were no differences in β-catenin and Fzd2 mRNA expression. In addition, we observed a significant increase of nuclear β-catenin in endometriotic lesions, a hallmark of Wnt/ β-catenin pathway activation. Stromal β-catenin staining was found in 45.4% of endometrial tissues and 77.8% of endometriotic lesions. β-catenin nuclear localization was found in 18.2% of the endometrial tissues and 33.3% of endometriotic lesions. Finally, the expression of galectin-3, a regulator of this pathway, was increased in endometriosis. In summary, this pattern of Wnt/β-catenin components expression suggests an increased activity of this pathway in endometriosis.

    ABSTRACT: Objective: Tight junction proteins have recently been reported to be useful for distinguishing between neoplastic and non-neoplastic tissues. In this study, we evaluated the expression and localization of tight junction transmembrane proteins in human cervical adenocarcinoma and adenocarcinoma in situ (AIS), and we determined whether their expression patterns could distinguish cervical adenocarcinoma from non-neoplastic cervical glands. Methods: Fifty-five patients with cervical adenocarcinoma or AIS were included in this study. Surgical specimens were immunohistochemically stained for claudin (CLDN) -1, -4, -7, occludin, and JAM-A. Results: Significantly higher expression levels of CLDNs and JAM-A were found in cervical AIS and adenocarcinoma than in non-neoplastic glands. In cervical AIS and adenocarcinoma, localization of CLDN1 and JAM-A was extended throughout the whole cell membranes, whereas they were predominantly expressed at the most apical cell-cell junction in non-neoplastic glands. ROC curve analysis revealed that immunoreactivities of CLDN-1 or JAM-A successfully distinguished neoplasms from non-neoplastic cervical glands with high specificity (CLDN-1, 79.1%; JAM-A, 79.1%) and high sensitivity (CLDN-1, 84.1%; JAM-A, 95.5%). Conclusions: As expected, there were immunohistochemical differences between cervical adenocarcinoma and non-neoplastic cervical glands by using antibodies against tight junction transmembrane proteins. These results suggest that CLDN-1 and JAM-A are potential biomarkers for cervical adenocarcinoma.

    ABSTRACT: Endometrial cancer (EC) is the most common gynecological malignancy in Europe and North America. It is classified into two types exhibiting different characteristics and prognosis. Type I is an estrogen-dependent tumor, histologically classified as low grade and low stage, usually with an excellent prognosis. Type II EC is unrelated to estrogen stimulation and is characterized by a poor prognosis. MicroRNAs (miRNAs, miRs) are small non-coding RNA polynucleotides that regulate gene expression post-transcriptionally. Various dysregulations in microRNA expression are often considered to have an impact on the diagnosis, prognosis and overall survival in patients diagnosed with different types of cancers. Recent data suggest that microRNAs play an important role in the pathogenesis of EC. The aim of the study was to evaluate the involvement of matrix metaloprotease 14 (MMP-14) and microRNA-410 in formation of the EC tumor. To this end expression of MMP-14 and microRNA-410 was assessed within the cancer, transient and healthy zones in the histological sections of tumours using immunohistochemical staining and laser capture microdissection (LCM) followed by a quantitative real-time PCR. The results revealed significantly higher expression of MMP-14 in the cancer tissue zone in comparison to the healthy tissue zone, as well as a lower expression of microRNA-410 in the cancer zone compared with the healthy zone. This reverse correlation may suggest a regulatory role of miRNA-410 in modulating levels of MMP-14 in EC. This is the first report on such regulation in human endometrial cancer.

    ABSTRACT: Despite efforts to optimize iodine supply in iodine deficient countries, iodine deficiency (ID) remains a global problem worldwide. Activation of the local microvasculature by ID in the thyroid gland aims at improving the local supply of iodide. For this purpose, the thyrocytes secrete vascular endothelial growth factor (VEGF) that acts on adjacent capillaries, via a reactive oxygen species (ROS)/Hypoxia Inducible factor (HIF)-dependent pathway. Beside the thyroid, other organs including salivary glands and the stomach do express the sodium/iodide symporter (NIS) and are able to take iodide up, potentially rendering them sensitive to ID. To verify this hypothesis, ID-induced effects on the local microvasculature were studied in salivary glands and in the stomach. ID was induced by feeding young mice with an iodide-deficient diet and NIS inhibitor perchlorate in the drinking water. In salivary glands, ID induced a transient increase in HIF-1α protein expression accompanied by a transient, VEGF-dependent increase in blood flow. In the gastric mucosa, ID transiently increased VEGF expression in the mucin-secreting epithelium and in ghrelin-secreting endocrine cells. These observations suggest that microvascular changes in response to ID occur in NIS-expressing tissues other than the thyroid. NIS expressing cells could be viewed as iodide sensors that respond to ID by inducing vascular changes, probably to optimize iodide bioavailability at regional or systemic levels.

    ABSTRACT: The molecular characterization of mechanisms involved in the gastrointestinal tract disorders needs an in vitro 3D culture model able to mimic the in vivo gastric microenvironment. Herein, we propose a 3D coculture system where gastric epithelial and stromal cells are grown together building spherical and solid structures using the NASA bioreactor - cell culture system (RCCS), a bioreactor. Epithelial and stromal cells from human antral gastric mucosa were isolated from endoscopic gastric biopsies. Thereafter, these cells were mechanically and enzymatically dispersed by treatment with dispase and collagenase, respectively. Using specific culture procedures, these cells formed 3D structures by using a RCCS, named "gastrospheres". Briefly, gastrospheres were obtained by initial seeding of 2.5x104 cells/well in 96 well culture plates. At 24 h after their formation, they were transferred into RCCS, and maintained for 7, 14, 21, and 28 days. The gastrospheres were morphologically characterized by immunocytochemisty to evaluate extracellular matrix (ECM), and by electron microscopy. These analysis of gastrospheres revealed that the epithelial cells were cytokeratin (CK) and lectin reactive and were arranged in the outer layer; stromal cells presented long cytoplasmic processes and were localized inside the gastrosphere. They were vimentin (VIM) and α-smooth muscle actin (α-SMA) positive and expressed ECM components such as laminin (LN), fibronectin (FN), and type IV collagen (CIV). Electron microscopy revealed groups of cohesive gastric cells surrounded by complex stromal structures, with multiple microvilli, and tight cellular junctions interspersed with extracellular matrix fibrils and fibers. The presence of some nestin-positive cells was observed in the inner region of the gastrospheres, suggesting an intermediary localization between epithelial and stromal cells. Altogether, our data suggest that in vitro gastrospheres recapitulate the in vivo gastric niche microenvironment.

    ABSTRACT: The aim of this study was to examine whether nanofiber scaffolds seeded with rabbit bone marrow mesenchymal stem cells (MSCs nanofibers) transferred onto the damaged corneal surface and covered with cyclosporine A (CsA)-loaded nanofiber scaffolds (CsA nanofibers) enable healing of the rabbit cornea injured with 1N NaOH. The healing of damaged corneas was examined morphologically, immunohistochemically and biochemically on day 24 after the injury. Compared to untreated injured corneas, where corneal ulceration or large corneal thinning or even perforation were developed, injured corneas treated with drug free nanofibers healed without profound disturbances in a majority of cases, although with fibrosis and scar formation. In injured corneas treated with CsA nanofibers or MSCs nanofibers, the development of scar formation was reduced. Best healing results were obtained with a combination of MSCs and CsA nanofibers (MSCs-CsA nanofibers). Corneas healed with highly restored transparency. Neovascularization highly expressed in untreated injured corneas and reduced in corneas treated with CsA nanofibers or MSCs nanofibers, was suppressed in corneas treated with MSCs-CsA nanofibers. The levels of matrix metalloproteinase 9, inducible nitric oxide synthase, interleukin 6, α-smooth muscle actin, tumor growth factor β and vascular endothelial growth factor were significantly decreased in these corneas as compared to untreated corneas, where the levels of the above mentioned markers were high. In conclusion, MSCs-CsA nanofibers were effective in the treatment of severe alkali-induced corneal injury.

    ABSTRACT: Tissue engineering of an anterior cruciate ligament (ACL) implant with ACL cells requires detailed analysis of the tissue characteristics that should be mimicked. Therefore, we studied the histological and biochemical properties of rabbit derived ACLs in comparison to other knee-associated tendons that are used as autografts in men. Rabbit derived ACLs and Musculus (M.) semimembranosus, M. semitendinosus tendons and patellar ligaments were explanted from adult New Zealand white rabbits and analyzed histologically for tissue organization (e.g. cellularity, nuclear shapes, elastic fibers), total collagen and sulfated glycosaminoglycan (sGAG) contents. Gene expression analysis was performed for the main extracellular matrix (ECM) components type I collagen, decorin and the glycoprotein tenomodulin. The ACLs had a dimension of 1.39 x 0.39 x 0.1 cm in situ. They were characterized by high sGAG content in comparison to the other tendons/ligaments, whereas the total collagen content did not differ. ACLs possessed higher cellularity and lower feret diameter of the cell nuclei compared with the investigated rabbit-derived tendons. In ACLs long elastic fibers were observed. Concerning the gene expression level, lower transcription of tenomodulin was detected in the ACL compared with the other tendons, without significant difference in the decorin gene expression. The M. semitendinosus tendon had a significantly higher type I collagen expression than the ACL and the other investigated tendons. This phenotypical characterization of the lapine ACL presented in this study provides some key standards to evaluate tissue engineered ACL constructs to be tested in the rabbit model.

    ABSTRACT: Almost 40 years ago, researchers found out that the Thomsen-Friedenreich (TF) and the Thomsen nouvelle (Tn) antigens could be detected in carcinoma, but not in healthy tissue. A short time after that it became clear that TF and Tn are precursor molecules of the MN-blood group antigens. In normal tissue TF and Tn are coated by glycosyl structures, thereby forming the glycoproteins which are known to account for the MN-blood group, but in malignant tissue these molecules are uncovered.TF, which has an additional Galectin-residue compared to Tn, is correlated with a more favourable prognosis for patients. On the contrary, patients with Tn-bearing tissues have a worse prognosis for overall and progression-free survival. It is known that TF and Tn are involved in the adhesion of tumour cells to the endothelium via a mechanism recruiting Galectin-3 and MUC-1, which is the first step in metastasis formation. Furthermore, it became clear that this pathway can be blocked by a growing number of molecules, thereby creating ways of therapeutical intervention.

    ABSTRACT: We herein analyzed the relationships between tropomyosin protein expression levels and clinicopathological factors in order to determine the significance of tropomyosins in lung cancers. Although neoplastic cells expressed different isoforms of tropomyosin, overall expression levels were lower than those in bronchial and alveolar epithelial cells. In adenocarcinomas, tropomyosin levels were markedly reduced in poorly differentiated or solid subtype carcinomas, suggesting that a loss in the expression of tropomyosins is involved in the progression of lung adenocarcinomas. The potential utility of the immunohistochemical expression of tropomyosins for a histopathological diagnosis was also investigated. The sensitivity and specificity of a loss in the expression of tropomyosins were 100% and 50%, respectively, which were superior to those for the strong expression of p53 (sensitivity 100% and specificity 44%), a conventional biomarker. An immunohistochemical examination of tropomyosins may assist in the histopathological detection of lung cancer cells in small biopsy specimens.

    ABSTRACT: We investigated whether Notch signaling was increased in an experimental liver fibrosis model and examined the effects of resveratrol on Notch expression. Rats were divided into four groups: the control group, injected with physiological saline; the CCl₄ group; the CCl₄ plus resveratrol group; and the resveratrol group. After treatment, immunostaining was performed to detect Notch1, Notch3, Notch4, transforming growth factor (TGF)-beta, alpha-smooth muscle actin (SMA), glial fibrillary acidic protein (GFAP), and proliferating cell nuclear antigen (PCNA), and TUNEL assays were performed to evaluate apoptosis. Sirius red staining was used to detect fibrosis. Samples were also biochemically evaluated for glutathione (GSH), glutathione peroxidase (GPx), catalase (CAT), lipid peroxidation, and protein oxidation. GSH, GPx, and catalase activities were significantly decreased (p⟨0.001) in the CCl₄ group. Distinct collagen accumulation was detected around the central vein and portal areas, and numbers of Notch1-, Notch3-, and Notch4-positive cells were significantly increased (p⟨0.001) in fibrotic areas in the CCl₄ group. Increased expression of Notch proteins in fibrotic areas may support the role of Notch in mediating signaling associated with liver fibrosis through activation of hepatic stellate and progenitor cells. In contrast, resveratrol prevented liver fibrosis by decreasing lipid peroxidation and may be effective for inhibiting Notch signaling.

    ABSTRACT: Stress-induced inflammatory responses in the portal system are characterized by elevations in serum concentrations of interleukin-6 (IL-6) and endotoxins such as lipopolysaccharides (LPS). LPS translocation from the intestinal to the capillary lumen occurs via LPS endocytosis by the capillary endothelium. Because the capillary endothelium of the small intestinal submucosa is fenestrated, we determined the role of pore modifications within the fenestrated endothelium in relaying inflammatory stress responses in the portal vein. We evaluated changes in the diameter and density of endothelial pores of the lamina propria of intestinal villi induced by continuous light (CL) exposure for 48 h and the correlation between these changes and serum IL-6 concentration in the portal vein in a rat model. We found significant increases in both the pore diameter and density, accompanied by a significant increase in portal IL-6 concentration; these changes were significantly attenuated by pretreatment with propranolol, a beta adrenergic receptor antagonist. In contrast, intravenous noradrenaline administration mimicked CL-induced modifications of the diameter and density of pores and the elevation of portal vein IL-6 concentration. These findings suggested that stress-induced inflammatory responses in the portal system may be a part of the modifications of the endothelial pores triggered by sympathetic activation.

    ABSTRACT: We herein examined the significance of the p53 expression in endometrial polyps (EMPs). A total of 133 EMPs, including 62 premenopausal and 71 postmenopausal women with EMP, were immunohistochemically studied for the expression of estrogen receptor (ER)-alpha, Ki-67 and p53. Apoptotic cells were identified using a TUNEL assay. A DNA sequence analysis of TP53 exons 5 to 9 was performed. Among the premenopausal EMPs, a multivariate analysis showed the labeling index (LI) for Ki-67 to correlate significantly with that for p53 (P<0.001), but not that for apoptosis. On the contrary, among the postmenopausal EMPs, the LI for Ki-67 correlated significantly with that for apoptosis (P<0.001). The p53 signature (p53S) was defined by endometrial epithelial cells, which are morphologically benign in appearance but display 12 or more consecutive epithelial cell nuclei with strong p53 immunostaining. The p53S was found in nine (12.7%) postmenopausal EMPs (mean age: 70.2 years). The median Ki-67 index for the p53S was 7%, with no significant difference from that of the glands of the postmenopausal EMPs without the p53S (P=0.058). The median apoptotic index for the p53S was 0%, which was significantly lower than that of the postmenopausal EMPs without the p53S (P=0.002). Two of four p53Ss showed TP53 mutations according to the DNA sequence analysis. The presence of the p53S is not rare in postmenopausal EMPs with an advanced age. Among postmenopausal EMPs, the LI of Ki-67 significantly correlates with that of apoptosis. However, such a positive correlation between the LI of Ki-67 and apoptosis is not observed in p53S.

    ABSTRACT: Long-term survival of lung allografts is limited by chronic rejection (CR). Oxidative stress (OxS) plays a central role in the development of CR. We investigated the influence of pirfenidone (alone or in combination with everolimus) on OxS and CR. A rat model of left lung allo-transplantation (F344-to-WKY) was used to evaluate the effects of pirfenidone alone [0,85% in chow from postoperative day (POD) -3 to 20/60] and in combination with everolimus [2,5 mg/kg bw daily from POD 7 to 20/60]. Allografts of non-treated animals, everolimus treated animals and right, non-transplanted lungs were used as references. Immunohistology of myeloperoxidase (MPO), haemoxygenase-1 (HO-1), iron and platelet-derived-growth-factor-receptor-alpha (PDGFR-a) were performed. On POD 20, all groups showed severe acute rejection (ISHLT A3-4/B1R-B2R). Groups treated with pirfenidone showed a lower interstitial inflammatory infiltration and a lower participation of highly fibrotic degenerated vessels (ISHLT-D2R). In the long term follow up (POD 60), pirfenidone alone significantly reduced chronic airway rejection (ISHLT-C; p<=0.05), interstitial fibrosis (IF; p<=0.05), content of collagen (p<=0.05), expression of PDGFR-a (p<=0.05) and the deposition of iron (p<=0.05). All groups treated with pirfenidone showed a high expression of the cytoprotective enzyme HO-1 (p<=0.05). The additional application of everolimus resulted in a significant decrease of chronic airway rejection (ISHLT-C; p<=0.05), vasculopathy (ISHLT; p<=0.05) and IF (p<=0.05). In conclusion, early application of pirfenidone inhibited the progression of CR by its anti-fibrotic and anti-oxidative properties. The additional application of an m-TOR-inhibitor increased the anti-fibrotic effects of pirfenidone which resulted in a reduction of CR after experimental LTx.

    ABSTRACT: Intra-nodal mesothelial cells are assumed to be indicative of metastatic mesothelioma. The invasion of benign mesothelial cells into lymph nodes is an extraordinary complication of different (mostly inflammatory) disorders involving the serosal cavities. In a cirrhotic patient with recurrent ascites, this report describes the first case of mesothelial cell spreading into lymphatic vessels, coexisting with non-malignant inclusions of mesothelial cells in multiple abdominal lymph nodes.

    ABSTRACT: Oral and esophageal candidiasis sometimes leads to mucosal hyperplasia, and progresses to carcinoma. We have produced an animal model for hyperplastic mucosal candidiasis in the forestomach that has a proliferative lesion of the squamous epithelium with chronic inflammation and C. albicans infection, some of which advanced to squamous cell carcinoma. There are many reports of the antibacterial effects of probiotics, but consensus about their antifungal effect has not been reached. In the present study, we investigate whether probiotic (yogurt) containing Lactobacillus gasseri OLL2716 (LG21 yogurt) can prevent proliferative and inflammatory changes caused by C. albicans in this mucosal candidiasis animal model. Diabetes was induced in 8-week-old WBN/Kob rats by intravenous administration of alloxan. One group of diabetic rats received a saline containing C. albicans and LG21 yogurt orally (DC+LG21 group) for 30 weeks, and another group received only C. albicans (DC group) for 30 weeks. They were sacrificed at 40 weeks of age, and analyzed histopathologically. In the DC+LG21 group, squamous hyperplasia at the greater curvature was significantly milder, and the Ki-67 positive index was significantly lower compared with the DC group. Suppurative inflammation with C. albicans also tended to be suppressed at the greater curvature. These findings suggest that probiotic (yogurt) containing Lactobacillus gasseri OLL2716 can suppress squamous hyperplastic change and inflammation associated with C. albicans infection in the forestomach.

    ABSTRACT: The discovery that the role human papillomavirus (HPV) plays in the induction of human cancer represents an important achievement in oncologic research. It has taken on even greater importance since the development of vaccines, which promise the hope of preventing these cancers from ever occurring. Because of these important implications, many have attempted to determine a possible role for the virus in cancers of the urinary bladder-an organ in close anatomic proximity to the primary sites of HPV-induced neoplasia and one which already has an established oncogenic infectious agent in Schistosoma haematobium. Here we review the current literature exploring this possible role in the most common subtype of cancer of the urinary bladder, urothelial carcinoma, and two much more rare histologic subtypes that have well established roles for HPV-induced neoplasia in other anatomic sites-squamous cell carcinoma and adenocarcinoma.
