Background: Previous studies have suggested that BRCA1 dysregulation has a role in triple-negative phenotypic manifestation. However, differences of BRCA1 expression, as a tumor suppressor gene, have rarely been investigated between luminal and triple-negative breast tumors. Therefore, the present study attempted to compare the BRCA1 expression in triple-negative with luminal breast tumors and its association with the clinicopathologic characteristics of patients. Methods: BRCA1 expression was evaluated by real-time PCR in 26 triple-negative and 27 luminal breast tumors...

Context • Outbreaks of the influenza A virus (IAV) are increasingly recognized as a global public health issue, affecting a large proportion of the world's population. A number of studies have provided epidemiologic evidence that dampness and mold are consistently associated with multiple allergic and respiratory effects, but they focused on dampness-related pathogenic microorganisms leading to allergy rather than the dampness itself. Objective • The current study intended to examine the effects of a damp environment on the promotion of the IAV and determine the adverse effects on its prognosis through upregulation of the toll-like receptor 7 (TLR7)-signaling pathway in the lung...

BACKGROUND AND AIMS: Several studies have confirmed the presence of bacterial DNA in atherosclerotic plaques, but its contribution to plaque stability and vulnerability is unclear. In this study, we investigated whether the bacterial plaque-profile differed between patients that were asymptomatic or symptomatic and whether there were local differences in the microbial composition within the plaque. METHODS: Plaques were removed by endarterectomy from asymptomatic and symptomatic patients and divided into three different regions known to show different histological vulnerability: A, upstream of the maximum stenosis; B, site for maximum stenosis; C, downstream of the maximum stenosis...

To develop effective therapeutics for inflammatory bowel disease (IBD), 2-benzylidene-2,3-dihydro-1H-inden-1-one and benzofuran-3(2H)-one derivatives, were designed and synthesized and their structure-activity relationships (SAR) were investigated. Compounds 7, 25, 26, 32, 39, 41, 52, 54, and 55 showed potent inhibitory effect (>70%) on the TNF-α-induced adhesion of monocytes to colon epithelial cells, which is one of the hallmark events leading to IBD. Such inhibitory activity of the compounds correlated with their suppressive activities against the TNF-α-induced production of ROS; ICAM-1 and MCP-1 expression, critical molecules involved in monocyte-epithelial adhesion; and NF-κB transcriptional activity...

The bipartite genomic RNAs of red clover necrotic mosaic virus (RCNMV) lack a 5' cap and a 3' poly(A) tail. RNA1 encodes viral replication proteins, and RNA2 encodes a movement protein (MP). These proteins are translated in a cap-independent manner. We previously identified two cis-acting RNA elements that cooperatively recruit eukaryotic translation initiation factor (eIF) complex eIF4F or eIFiso4F to RNA1. Such cis-acting RNA elements and host factors have not been identified in RNA2. Here we found that translation of RNA1 was significantly compromised in Arabidopsis thaliana carrying eif4f mutation...

Large-scale sequencing studies have revealed several genes that are recurrently mutated in melanomas. To annotate the melanoma genome we have expressed tumor-associated variants of these genes in zebrafish and characterized their effects on melanocyte development and function. Here, we describe expression of tumor-associated variants of the recurrently-mutated metabotropic glutamate receptor 3 (GRM3) gene. Unlike wild-type GRM3, tumor-associated GRM3 variants disrupted trafficking of melanosomes, causing their aggregation in the cell body...

Biologics are indicated for treating moderate to severe psoriasis. As the number of biologics registered for psoriasis increases, so does the need for biomarkers to guide personalized therapeutic decisions. Genetic variants might serve as predictors for treatment response, a field of research known as pharmacogenetics. The aim of this systematic review was to assess which genetic variants are associated with the response to biologics in psoriasis patients. A systematic search was performed in EMBASE, MEDLINE, the Cochrane Library and Web of Science...

Voltage gated calcium channels (VGCCs) play important roles in physiological functions including modulations of neurotransmitter release, neuronal network activities, intracellular signaling pathways, and gene expression. Some pathological conditions, including nerve injuries, can cause dysregulation of VGCCs and their subunits. This in turn can lead to functional maladaption of VGCCs and their subunits, which can contribute to development of disorders such as pain sensations. This review summarized recent findings related to maladaptive changes of dysregulated VGCC alpha-2-delta-1 subunit (Cav α2 δ1 ) with a focus on exploration of mechanisms underlying contribution of Cav α2 δ1 to pain signal transduction...
