Uveal melanoma (UM) is the most common primary intraocular tumor in adults and it carries a high risk of metastasis and mortality. Various pro-inflammatory cytokines have been found to be significantly increased in the aqueous humor or vitreous fluid of UM patients; however, the role of these cytokines in UM metastasis remains elusive. In this study, we found that long-term IL-6 exposure promoted the migration and invasion of UM cells, diminished cell-cell adhesion, and enhanced focal adhesion. Moreover, IL-6 treatment decreased the membranous epithelial marker TJP1 and increased the cytoplasmic mesenchymal marker Vimentin...

BACKGROUND: Gastric cancer (GC) is one of the high-incidence and high-mortality cancers all over the world. Though genome-wide association studies (GWASs) have found some genetic loci related to GC, they could only explain a small fraction of the potential pathogenesis for GC. METHODS: We used multi-marker analysis of genomic annotation (MAGMA) to analyze pathways from four public pathway databases based on Chinese GWAS data including 2631 GC cases and 4373 controls...

Introduction: Colorectal cancer (CRC) is the fourth most common cause of cancer-related mortality worldwide. The tumor, node, metastasis (TNM) stage remains the standard for CRC prognostication. Identification of meaningful microRNA (miRNA) and gene modules or representative biomarkers related to the pathological stage of colon cancer helps to predict prognosis and reveal the mechanisms behind cancer progression. Materials and methods: We applied a systems biology approach by combining differential expression analysis and weighted gene co-expression network analysis (WGCNA) to detect the pathological stage-related miRNA and gene modules and construct a miRNA-gene network...

Background: Biomarkers of systemic inflammation predict non-AIDS events and overall mortality in virologically suppressed HIV-1-infected patients. Objectives: To determine whether switching to a dual antiretroviral maintenance therapy was associated with modification of biomarkers of systemic inflammation as compared with continuation of successful standard triple therapy. Methods: In this substudy of the randomized ATLAS-M trial, we compared in virologically suppressed patients the impact at 1 year of simplification to a dual therapy with atazanavir/ritonavir plus lamivudine versus maintaining atazanavir/ritonavir plus two NRTI triple therapy on markers of systemic inflammation...

BACKGROUND: The right drug to the right patient at the right time is one of the ideals of Individualized Medicine (IM) and remains one of the most compelling promises of the post-genomic age. The addition of genomic information is expected to increase the precision of an individual patient's treatment, resulting in improved outcomes. While pilot studies have been encouraging, key aspects of interpreting tumor genomics information, such as somatic activation of drug transport or metabolism, have not been systematically evaluated...

Glioblastoma multiforme (GBM) is the most common brain tumor in adults. Due to its highly invasive nature, it is not easy to treat, resulting in high mortality rates. Stromal interacting molecule 1 (Stim1) plays important roles in regulating store-operated Ca2+ entry (SOCE), and controls invasion by cancer cells. However, the mechanisms and functions of Stim1 in glioma progression are still unclear. In this study, we investigated the effects of targeting Stim1 expression on glioma cell invasion. By analyzing profiles of GBM patients from RNA-sequencing data in The Cancer Genome Atlas (TCGA), higher expression levels of STIM1 were correlated with the poor survival...

Purpose: Globally, colorectal cancer (CRC) is one of the most common cancers with high mortality. Although CRC patients in stages I-II are curable after surgical resection, due to the lack of sensitive and specific biomarkers, many patients are in the advanced stages when diagnosed. This study aimed to investigate whether circulating miRNAs in plasma could act as biomarkers for early CRC diagnosis. Patients and methods: All healthy subjects and patients were from Nanjing First Hospital...

BACKGROUND/AIMS: Colorectal cancer (CRC) is a malignancy that has high morbidity and mortality and is initiated from accumulative genetic events. Although much effort has been made to elucidate the genetic mechanism underlying this disease, it still remains unknown. Here, we discovered a novel role for multiple epidermal growth factor-like domains protein 6 (MEGF6) in CRC, namely, that it induces the epithelial-to-mesenchymal transition (EMT) to promote CRC metastasis via the transforming growth factor beta (TGFβ)/SMAD signaling pathway...

Malignancy of the pancreas is a leading cause of cancer-related mortality, with the highest case-fatality of all cancers. Nevertheless, the lack of sensitive biomarkers and presence of biological heterogeneity precludes its early detection and effective treatment. The recent introduction of next-generation sequencing allows characterization of multiple driver mutations at genome- and exome-wide levels. Sequencing of DNA and RNA from circulating tumour cells has also opened an exciting era of non-invasive procedures for tumour detection and prognostication...

Endometrial cancer (EC) is now the most prevalent gynaecological malignancy in the Western world. Black or African American women (BoAA) have double the mortality of Caucasian women, and their tumours tend to be of higher grade. Despite these disparities, little is known regarding the mutational landscape of EC between races. Hence, we wished to investigate the molecular features of ECs within The Cancer Genome Atlas (TCGA) dataset by racial groupings. In total 374 Caucasian, 109 BoAA and 20 Asian patients were included in the analysis...

Glioblastoma multiforme (GBM), the most common and aggressive primary brain tumor, has a high mortality rate despite extensive efforts to develop new treatments. GBM exhibits both intra- and intertumor heterogeneity, lending to resistance and eventual tumor recurrence. Large-scale genomic and proteomic analysis of GBM tumors has uncovered potential drug targets. Effective and "druggable" targets must be validated to embark on a robust medicinal chemistry campaign culminating in the discovery of clinical candidates...

The pathophysiology of atherosclerosis involves a diseased endothelium, lipid accumulation and low-grade inflammation. In later stages of coronary artery disease (CAD) and peripheral arterial disease (PAD), plaque rupture may induce atherothrombosis caused by fibrin formation and platelet activation, leading to vessel occlusion with subsequent organ damage such as myocardial infarction, stroke or limb ischaemia. Because of the high disease burden associated with CAD and PAD, there is a need for continuous vascular protection beyond currently available treatments including antiplatelet agents...

Primary infection with human cytomegalovirus (HCMV) results in a lifelong infection due to its ability to establish latent infection, with one characterized viral reservoir being hematopoietic cells. Although reactivation from latency causes serious disease in immunocompromised individuals, our molecular understanding of latency is limited. Here, we delineate viral gene expression during natural HCMV persistent infection by analyzing the massive transcriptome RNA sequencing (RNA-seq) atlas generated by the Genotype-Tissue Expression (GTEx) project...

Gastric cancer (GC) has a high incidence and mortality rate. If discovered late, GC tends to have a poor prognosis. Improvements in the prognostic accuracy of GC through combined analysis of multiple relevant genes and clinical factors may solve this problem. In the present study, GSE62254 (including 300 GC tissues), obtained from the Gene Expression Omnibus database, was used as a training set, and the mRNA‑sequencing data of GC (including 384 GC tissues) downloaded from the Cancer Genome Atlas database served as a validation set...
