Melatonin therapy or prolonged exposure to complete darkness reduces biliary hyperplasia and liver fibrosis in bile-duct-ligated (BDL) rats; however, no information exists in primary sclerosing cholangitis (PSC). Thus, we aimed to determine the therapeutic effects of prolonged dark therapy or melatonin administration on hepatic fibrosis in the Mdr2(-/-) mouse model of PSC. Melatonin levels, biliary mass, liver fibrosis, angiogenesis and miR-200b expression were evaluated in wild-type and Mdr2(-/-) mice exposed to darkness or melatonin treatment or in male PSC patient samples and healthy controls...

Exposure to ionizing radiation from nuclear devices, spaceflights or terrorist attacks represents a major threat to human health and public security. After a radiological incident, noninvasive biomarkers that can facilitate rapid assessment of exposure risk in the early stages are urgently needed for optimal medical treatment. Serum microRNAs (miRNAs) are ideal biomarkers because they are stable in response to environmental changes, they are common among different species and are easily collected. Here, we performed miRNA PCR arrays to analyze miRNA expression profiles at 24 h postirradiation...

MiRNAs (microRNA) constitute a large family of single-stranded, non-coding small RNAs. Although the functions and target genes of most miRNAs are still unknown, it has been well established that they are involved in embryogenesis, organogenesis and neonatal birth. In recent decades, interest in buffalo breeding has largely increased worldwide thus focusing the attention on this species as a dairy purpose animal. Problems related to long calving interval, late puberty and seasonal anestrus hamper reproductive efficiency in this species...

Rho GTPases activated in cancer cells drive proliferation, migration and metastasis. Thus, RhoGAP proteins which negatively regulate Rho GTPases are generally thought to function as tumor suppressors. Here this expectation was challenged by characterization of ARHGAP18, a RhoGAP family member that is selectively overexpressed in highly migratory triple negative breast cancer (TNBC) cells. In human breast tumors, higher ARHGAP18 levels associated with worse overall survival, recurrence-free survival and metastasis-free survival...

Metastasis is a multistep process by which tumor cells disseminate from their primary site and form secondary tumors at a distant site. The pathophysiological course of metastasis is mediated by the dynamic plasticity of cancer cells, which enables them to shift between epithelial and mesenchymal phenotypes through a transcriptionally regulated program termed epithelial-to-mesenchymal transition (EMT) and its reverse process, mesenchymal-to-epithelial transition (MET). Using a mouse model of spontaneous metastatic breast cancer, we investigated the molecular mediators of metastatic competence within a heterogeneous primary tumor and how these cells then manipulated their epithelial-mesenchymal plasticity during the metastatic process...

MicroRNA-200b (miR-200b) is a tumor suppressor in multiple tumor types, including gastric cancer, breast cancer, ovarian cancer and glioma. The biological significance of a known normal and cancer stem cell marker, CD133, remains elusive. The aim of the present study was to identify the function and mechinism of miR-200b in suppressing CD133(+) glioma cells. CD133(+) glioma cells were sorted by flow cytometry. The expression of miR-200b, Ki67, GAP43, GFAP and CD133 were tested by reverse transcription-quantitative polymerase chain reaction...

BACKGROUND AND AIMS: Chronic allograft dysfunction (CAD) is the major cause of renal allograft loss and can only be diagnosed by invasive histological examinations. The current study aimed to determine whether or not the circulating miR-125a, miR-150, miR-192, miR-200b, miR-423-3p and miR-433 could serve as predictors of graft outcome in the renal transplant recipients with CAD. METHODS: To evaluate the expression levels of miRNAs, we used quantitative real-time PCR (qPCR) and analyzed the plasma samples of 53 renal transplant recipients, including: 27 recipients with stable graft function (SGF), 26 recipients with biopsy-proven interstitial fibrosis and tubular atrophy (IFTA) and 15 healthy controls...

The aim of this study was to determine the gene- and microRNA-expression profile contributing to epithelial to mesenchymal transition in a rat model of experimental colitis. For this, inflammation was induced by injecting 2,4,6-trinitrobenzene sulphonic acid to the colon of male Wistar rats. Samples were taken from both inflamed and uninflamed regions of the same colon, total RNA was isolated, and the mRNA and microRNA expressions were monitored. We have determined that the expression of genes responsible for inducing mesenchymal phenotype, such as Egr1, Fgf2, Fgf7, Jak2, Notch2, Hif1α, Zeb2, Mmp9, Lox, and Vim, was all significantly induced in the inflamed regions of the affected colons while the epithelial marker E-cadherin (Cdh1) was downregulated...

BACKGROUND: The microRNA-200 (miR-200) family acts as a major suppressor of epithelial-mesenchymal transition (EMT). Impaired miR-200 expression may lead to EMT initiation and eventually cancer dissemination. The presence of tumor budding cells (TBC) is associated with metastasis and poor prognosis, and molecular similarities to EMT indicate that these cells may reflect ongoing EMT. The aim of this study was to investigate the expression of miR-200b in budding cells of colon cancer and the relationship with the EMT-markers E-cadherin, β-catenin and laminin-5γ2...

Cellular interactions in the tumor microenvironment influence neoplastic progression in pancreatic ductal adenocarcinoma. One underlying mechanism is the induction of the prognostically unfavorable epithelial-mesenchymal-transition-like tumor budding. Our aim is to explore the expression of microRNAs implicated in the regulation of tumor budding focusing on the microenvironment of the invasive front. To this end, RNA from laser-capture-microdissected material of the main tumor, tumor buds, juxta-tumoral stroma, tumor-remote stroma, and non-neoplastic pancreatic parenchyma from pancreatic cancer cases with (n=7) and without (n=6) tumor budding was analyzed by qRT-PCR for the expression of a panel of miRNAs that are known to be implicated in the regulation of epithelial-mesenchymal transition, including miR-21, miR-183, miR-200b, miR-200c, miR-203, miR-205, miR-210, and miR-217...

This study investigated the role of cancer/testis antigen DDX53 in regulating cancer stem cell-like properties. DDX53 shows co-expression with CD133, a marker for cancer stem cells. DDX53 directly regulates the SOX-2 expression in anticancer drug-resistant Malme3M(R) cells. DDX53 and miR-200b were found to be involved in the regulation of tumor spheroid forming potential of Malme3M and Malme3M(R) cells. Furthermore, the self-renewal activity and the tumorigenic potential of Malme3M(R)-CD133 (+) cells were also regulated by DDX53...

Endometrial carcinoma (EC) is one of the most common gynecologic malignancy, but molecular mechanisms of the development and progression of EC remain unclear. Here we showed that the expression of DICER1 was negatively associated with the level of histone methylation, histone acetylation and PRC2 components SUZ12 and EZH2 in EC cells. In addition, knockdown of DICER1 significantly downregulated miR-200b and let-7i, which may then regulate their targets SUZ12 and EZH2. Furthermore, knockdown of DICER1 remarkably suppressed the expression of epithelial cell marker E-cadherin, induced the expression of mesenchymal cell marker Vimentin, and promoted the invasion of EC cells...

The kidding rate is one of the most important economic traits for goat production, but the genetic mechanism that is associated with ovulation rate is poorly understood. Recently, increasing evidence has suggested that microRNAs (miRNAs) influence ovarian biological processes. The present study provides the first comparison of the ovarian miRNAs of prolific Jintang black goats (JTGs) and non-prolific Tibetan goats (TBGs) during the follicular phase using RNA-Seq technology. We generated 11.19 million (M) and 11...

Hepatic fibrosis occurs during the progression of primary sclerosing cholangitis (PSC) and is characterized by accumulation of extracellular matrix proteins. Proliferating cholangiocytes and activated hepatic stellate cells (HSCs) participate in the promotion of liver fibrosis during cholestasis. Gonadotropin-releasing hormone (GnRH) is a trophic peptide hormone synthesized by hypothalamic neurons and the biliary epithelium and exerts its biological effects on cholangiocytes by interaction with the receptor subtype (GnRHR1) expressed by cholangiocytes and HSCs...

Long noncoding RNAs (lncRNAs) are frequently dysregulated and have important roles in many diseases, particular in cancers. lncRNA-HEIH was first identified in hepatocellular carcinoma. The expression, clinical significances and roles of lncRNA-HEIH in melanoma are still unknown. In this study, we found that lncRNA-HEIH is highly expressed in melanoma tissues and cell lines, associated with advanced clinical stages, and predicts poor outcome of melanoma patients. Functional assays showed that ectopic expression of lncRNA-HEIH promotes melanoma cell proliferation, migration and invasion...
