BACKGROUND: Lifetime risk of developing endometrial cancer is 2.17%. There is controversy regarding the predictive value of Cancer Antigen 125 (CA125) in endometrial cancer as well as the significance of its relationship with prognostic factors and appropriate cut-off value. OBJECTIVE: The aim of the present study was to investigate the prognostic role of CA125 in advanced endometrial carcinoma and determination of the appropriate cut-off value. METHODS: A sample of 91 patients was retrospectively selected from a population of 501 patients suffering from endometrial cancer during 1995 to 2015 in accordance with the inclusion criteria...

miR-99a is down-regulated in esophageal squamous cell carcinoma (ESCC), however the role and underlying mechanism are still unknown. We aim to explore the role and mechanism of miR-99a down-regulation in ESCC. The expression of miR-99a in ESCC tissues and cell lines was detected by Human miRNA Microarrays and Real-time PCR. The effects of miR-99a on cell proliferation, migration and invasion were determined by Cell Counting Kit-8 (CCK-8) assay, transwell migration and invasion assay. Target gene of miR-99a were analyzed by target prediction software and validated by Real-time PCR and Western blotting assay...

BACKGROUND: Pyrosequencing is recognized as a strong technique to analyze the MGMT status of glioblastoma patients. The most commonly used assay, quantifies the methylation levels of CpGs 74 to 78. A more recent CE-marked In Vitro Diagnostic Medical Device (CE-IVD) assay, Therascreen, analyzes CpGs 76-79. METHODS: We performed a comparison of these two assays to evaluate the potential impact of this shift in analyzed CpGs. Therascreen analysis was centrally performed for 102 glioblastoma patients, who were part of a prospective multicenter trial...

According to the American Association of Cancer Research (AACR), a Cancer Stem Cell is a cell within a tumor that possesses the capacity to self-renew and to cause the heterogeneous lineages of cancer cells that constitutes the tumor [1]. Cancer Stem Cells (CSCs) are involved in the metastatic process, in the resistance to therapeutic treatments of many types of human cancers and consequently in the onset of recurrences. Numerous translational studies have been conducted to understand CSC characteristics and evaluate association between CSC-related biomarkers and clinical outcomes...

Studies have shown that microRNAs (miRNAs) can promote or suppress tumor growth and therefore act as targets for cancer therapy. Hsa-miR-503-5p, a mature miRNA derived from 5' ends of pre-miR-503, has been proved to regulate cell proliferation, transformation, migration and invasion. However, the biological function of miR-503-3p derived from 3' ends of pre-miR-503 has never been reported. In current study, we found that miR-503-3p inhibits lung cancer cell viability and induces cell apoptosis. To better understand the molecular mechanism underlying the miR-503-3p participating in this process, PCR array and RNA-sequencing (RNA-seq) were performed and some differential expression genes were discovered between NC and miR-503-3p treated groups...

Neuroblastoma is a brain malignancy of childhood and accounts for 7-10% of childhood cancers, leading to approximately 15% of pediatric cancer deaths. MicroRNAs (miRNAs) are a family of short (about 18-25 nucleotides), noncoding and single stranded endogenous RNAs, which complementarily bind to the 3' untranslated regions of their target genes. Recently, glutamine metabolism has been recognized as an important nutrition source for tumor cells, and hence targeting glutamine metabolism could benefit to development of anti-cancer agents...

BACKGROUND: NIMA-related kinase 2 (NEK2), a serine/threonine kinase, is located in the centrosome and is a member of cell cycle regulation related protein kinase (CCRK) family. Aberrant expression of NEK2 is linked with carcinogenesis and progression of various tumors. OBJECTIVE: To investigate the expression level of NEK2 and its relationship with clinicopathological factors in hepatocellular carcinoma (HCC). METHODS: Immunohistochemistry was used to measure the expression of NEK2 in 310 patients' specimen tissues and 197 adjacent normal liver tissues of HCC cases, and the subsequent prognostic value for each sample was estimated...

Long non-coding RNAs (lncRNAs) are aberrantly expressed in various cancers. Fer-1-like protein 4 (FER1L4), one of lncRNAs, plays a role as tumor suppressor in various human cancers and can be regulated by microRNA. However, the role and function of FER1L4 in human hepatocellular carcinoma (HCC) remains unknown. The aim of the present study was to annotate the role of FER1L4 and its clinical value in HCC. In the present study, we found that FER1L4 was lowly expressed in HCC tissue specimens as well as in malignant HCC cell lines, while the situation is opposite in miR-106a-5p...
