Surprisingly, increased levels of MAdCAM-1 were detected in transgenic animals expressing enzymatically inactive hVAP-1. Although these find more levels were not generally as high as those seen in mice overexpressing enzymatically intact hVAP-1, we suggest

that VAP-1 might also induce MAdCAM-1 by acting as an adhesion molecule and recruiting lymphocytes that then secrete factors promoting MAdCAM-1 induction. In conclusion, our data reveal that VAP-1/SSAO contributes to MAdCAM-1 induction in HECs in vitro and ex vivo in humans and in gut mucosal vessels in vivo in mice. On the basis of these findings and previous reports describing the induction of VAP-1 during gut inflammation,16 we suggest that MA at increased levels due to enhanced absorption via an inflamed gut or cigarette smoke15 acts as a substrate for VAP-1/SSAO and thus leads to MAdCAM-1 expression in the inflamed gut mucosa and hepatic endothelium. This could promote the uncontrolled recruitment of mucosal effector cells and result in tissue damage that is characteristic of both IBD and its hepatic complications. Thus, targeting VAP-1/SSAO therapeutically could not only reduce lymphocyte adhesion directly but could also down-regulate Ganetespib MAdCAM-1 expression and lead to the resolution of both liver

and gut inflammation. The authors thank K. Auvinen for her practical advice and R. Sjoroos for her expert technical assistance with the adenoviruses. They also kindly thank M.

“The presence of cirrhosis increases the potential risk of hemorrhage for patients with hepatocellular carcinoma (HCC). We evaluated the relative risk for hemorrhage in patients with HCC treated with antiangiogenic agents. We performed a systematic review and meta-analysis of antiangiogenic studies in HCC from 1995 to 2011. For nonrandomized studies we compared bleeding risk with other HCC single-arm studies that did not include an antiangiogenic agent. To separate disease-specific factors we also performed a comparison analysis with renal cell cancer (RCC)) studies that evaluated sorafenib. Sorafenib was associated with increased bleeding risk compared to control for all grade bleeding events (odds ratio [OR] 1.77; 95% confidence interval [CI] 1.04, 3.0) but not grade 3-5 events in both HCC and RCC (OR 1.46; 95% CI 0.9, 2.36; P = 0.45). When comparing the risk of bleeding in single-arm phase 2 studies evaluating antiangiogenic agents, this risk for all events (OR 4.34; 95% CI 2.16, 8.73) was increased compared to control.
