We report that BART plays a role in inhibiting cell invasion by regulating the activity of the Rho GTPase protein RhoA in pancreatic cancer cells. BART was originally identified as a binding partner of ARL2, a small G-protein implicated as a regulator of microtubule dynamics and folding. We show that BART interacts with GTP-bound ARL2 and is required for the binding of GTP-bound ARL2 with activ...

The human herpes virus Epstein-Barr virus (EBV) latently infects and drives the proliferation of B lymphocytes in vitro and is associated with several forms of lymphoma and carcinoma in vivo. The virus encodes ~30 miRNAs in the BART region, the function of most of which remains elusive. Here we have used a new mouse xenograft model of EBV driven carcinomagenesis to demonstrate that the BART miR...

The present study (N = 86) sought to evaluate a laboratory-based behavioral measure of risk taking (the Balloon Analogue Risk Task; BART) and to test associations between this measure and self-report measures of risk-related constructs as well as self-reported real-world risk behaviors. The BART evidenced sound experimental properties, and riskiness on the BART was correlated with scores on mea...

Here we describe a method for the detection of Clostridium difficile from stool using a novel low-complexity and rapid extraction process called Heat Elution (HE). The HE method is two-step and takes just 10 minutes, no specialist instruments are required and there is minimal hands-on time. A test method using HE was developed in conjunction with Loop-mediated Isothermal Amplification (LAMP) co...

Models of risk-taking typically assume that the variability of outcomes is important in the likelihood of making a risky choice. In an animal model of the Balloon Analogue Risk Task (BART), within-session variability, or the coefficient of variability (CV), was found to be a novel predictor of behavior (Jentsch et al., 2010). Human studies have not investigated how BART performance differs when...

UNLABELLED Epstein-Barr virus (EBV) expresses few viral proteins in nasopharyngeal carcinoma (NPC) but high levels of BamHI-A rightward transcripts (BARTs), which include long noncoding RNAs (lncRNAs) and BART microRNAs (miRNAs). It is hypothesized that the mechanism for regulation of BARTs may relate to EBV pathogenesis in NPC. We showed that nuclear factor-κB (NF-κB) activates the BART promot...
