The prognosis for patients with bladder cancer, especially muscle-invasive bladder cancer, remains poor despite systemic therapy. OBJECTIVE: To explore the underlying disease mechanisms and identify more effective biomarkers for bladder cancer. METHODS: Weighted gene co-expression network analysis (WGCNA) and protein-protein interaction (PPI) network analysis were applied to identify hub genes correlated with the bladder cancer progression...

BACKGROUND: Colorectal cancer (CRC) is the most common malignant disease worldwide and thus new therapeutic approaches are needed. 5-Fluorouracil (5-FU) remains the most widely used agent to treat colorectal cancer (CRC). However, its clinical efficacy is currently limited by the development of drug resistance. Esculetin (EST), a coumarin, was found to have anti-proliferative and anti-migration activity in cancer. OBJECTIVE: This research aims to evaluated the influence and possible mechanism of EST on the proliferation, migration and epithelial-mesenchymal transition of CRC cell lines...

BACKGROUND: Circular RNAs (circRNA) play key regulatory roles in cancer progression. Human circRNA microarray was performed to screen for abnormally expressed circRNA in gastric cancer tissues. In this study, we found circRNA102958 was up-regulated in gastric cancer tissues and cell lines. METHODS: The hsa_circRNA_102958 levels were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) in gastric tissue and cell. Then, the association between the expression level of hsa_circRNA_102958 and the clinicopathological features of patients with gastric cancer was further analyzed...

BACKGROUND: DNA methylation status is one of the most prevalent molecular alterations in human cancers. Identification of powerful diagnostic and prognostic biomarkers for hepatocellular carcinoma (HCC) without a biopsy is urgently required. OBJECTIVE: The purpose of this study was to determine the methylation status of RASSIF1A and SOCS-1genes as a non-invasive biomarker for HCC identification and prognosis. METHODS: Methylation specific-PCR technique was performed to recognize the methylation status of RASSIF1A and SOCS-1 genes in 100 patients with HCC, 100 patients with liver cirrhosis (LC) but without HCC were considered as cirrhotic liver control group and 100 healthy control...

BACKGROUND: A growing body of studies has demonstrated the aberrant expression of microRNAs (miRNAs) contributes to human tumor metastasis. MicroRNA-124-3p (miR-124-3p), which is down-regulated in various cancers, has been found to be involved in several signaling pathways relevant to tumor cell migration and invasion. However, the roles of miR-124-3p in human bladder cancer remain unclear. This study aims to investigate the functional significance of miR-124-3p and to understand how it targets the integrin receptor, and thus affects the progression of human bladder cancer...

Lung cancer represents a major healthy concern due to high incidence and morality. Increasing evidences showed critical regulatory role of microRNA (miR) in cell growth, differentiation and apoptosis. It has been indicated that the level of miR-328 is abnormally up regulated in lung cancer cell line, which is correlated with cell apoptosis. An in vitro lung cancer model was established through induction of chlamydia pneumonia. Western blot and real-time quantitative PCR were used to measure miR-328 level and its effects on histone H2AX expression...

Oral squamous cell carcinoma (OSCC) is a complex disease with extensive genetic and epigenetic defects, including microRNA deregulation. The aims of the present study were to explore the regulatory mechanism of microRNA-18a in OSCC cells proliferation and metastasis. Quantitative real-time PCR (qRT-PCR) was used to detect the expression level of miR-18a and KLF4 mRNA in OSCC tissues and cell lines (SCC-25, CAL-27, Tca-8113). Western-blot analysis was used to validate expression of KLF4 protein. CCK-8 assay was performed to e validate the proliferous ability of human OSCC cells...

OBJECTIVE: Human multiple myeloma (MM) is a kind of common tumor in middle-aged and elderly people, in which the osteolytic lesion is formed mainly through inhibiting osteoblast (OB) differentiation and promoting osteoclast (OC) differentiation. Dickkopf-1 (DKK1) is a soluble Wnt inhibitor, which has an important correlation with the pathogenesis of human MM. Therefore, the correlations of DKK1 with pathogenesis and prognosis of human MM were investigated in this study. METHODS: The DKK1 expression in tissues and serum of myeloma patients was detected via immunohistochemistry and enzyme-linked immunosorbent assay (ELISA)...

Gallbladder carcinoma (GC) occupies more than 90% of all cancers in biliary tract with an increasing incidence. Most patients with GC are already at terminal stage at the time of primary diagnosis, causing unfavorable prognosis and high mortality. Transformation growth factor-beta (TGF-β) is up-regulated in GC. However, the mechanism by how TGF-β is involved in GC remains unclear. The aim of this study was to investigate the effect and mechanism of TGF-β in GC using GC cell line NOZ cells.In vitro cultured NOZ cell was randomly assigned into control, si-NC and TGF-β1 siRNA groups and were transfected with siRNA negative control (NC) or TGF-β1 siRNA followed by analysis of TGF-β1 expression by Real-time PCR, cell proliferation by MTT assay, cell apoptosis and cell invasion, as well as expression of proteins in epithelial-mesenchymal transition (EMT), p38, Smad2/3 and Smad4 phosphorylation by Western blot, Insulin-like growth factor-binding protein-2 (IGFBP-2) level by ELISA...

BACKGROUND: Both QKI and TMEFF2 genes are considered putative tumor suppressor genes (TSGs). In gastric (GC) and colorectal (CRC) cancers, downregulation of their expressions is known to be frequent. However, QKI and TMEFF2 mutations that could potentially inactivate their functions are not reported in cancers. METHODS: In a genome database, we observed that both QKI and TMEFF2 harbor mononucleotide repeats, which could be mutated in cancers with high microsatellite instability (MSI-H)...

MicroRNAs (miRNAs) have been demonstrated that play a critical role in tumorigenesis. The aim of this study is to identify the functional role of miR-378 in cholangiocarcinoma (CCA). Quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure the expression levels of miR-378 in human CCA tissue samples and CCA cell lines. The receiver operating characteristic (ROC) curve was established, and the area under the ROC curve (AUC) was calculated to estimate the capacity of miR-378 in distinguishing CCA patients with different TNM stages...

BACKGROUND: Endometrioid ovarian carcinoma and clear cell ovarian carcinoma are both classified as endometriosis-associated ovarian cancer (EAOC). Despite the high rates of recurrence and mortality of EAOC, no prognostic biomarkers have been determined. ADP-ribosylation factor-like protein 4C (ARL4C) has been reported to be involved in various tumor progression processes, but its clinical significance for predicting prognosis in EAOC cases has never been studied. OBJECTIVE: The present study aimed to determine the clinical significance of ARL4C expression in EAOC prognosis...

BACKGROUND: Altered expressions of miR-186, miR-494 and miR-3651 in whole blood of OSCC patients have already been demonstrated. However, nothing is known about their expression in tumor tissues. This study aimed at evaluating differences in miRNA expression in OSCC tissues compared to healthy oral mucosa and at checking if the altered expression is reflected in corresponding blood. METHODS: In 53 OSCC and 40 healthy mucosal tissues the expression of miR-186, -494 and -3651 was determined by RT-qPCR and expression levels were compared between the groups...
