28 The significant inhibition of these processes by the targeted construct and not by native IFNγ further highlights the potency of our targeting approach. Adverse effects have been the main reason for patient withdrawal from clinical

trials with IFNγ. IFNγ is a very potent proinflammatory cytokine with a ubiquitous receptor expression, and therefore IFNγ-based experimental therapies are associated with side effects like PDGFR inhibitor severe flu-like symptoms, systemic endothelial and immune cell activation, neurotropic effects, and hyperlipidemia. In our study we observed that both free IFNγ and PEGylated IFNγ induced hyperthermia, elevated plasma triglyceride levels, endothelial cell activation, serum TNF-α and IL-6 levels, and CNS inflammation. Notably, these adverse reactions were completely absent following IFNγ-PEG-PPB administration. In this website conclusion, we report here a novel approach of

chemically engineering a cytokine to shift its receptor specificity by directing it to the myofibroblast-like cells (activated HSC) in liver. Using this approach, targeting of IFNγ ameliorated advanced liver fibrosis and eliminated the IFNγ-related adverse effects. We believe that this illustrates new opportunities to utilize cytokines more effectively for therapy of hepatic fibrosis. We thank C. Reker-Smit, A. de Jager-Krikken, and M. de Ruiter for their technical assistance. Additional Supporting Information may be found in the online version of this article. “
“It is reasonable to investigate non-tumor

liver tissues to predict a risk for development of hepatocellular carcinoma (HCC). A molecular analysis of chronically damaged liver tissues may identify specific miRNA expression profiles associated with a risk for multicentric (MC) HCC. Twenty HCC patients, who underwent a curative hepatectomy were classified into two groups: a non-MC group (no MC recurrence in more than 3 years, n = 10) and an MC group (MC recurrence within 3 years after hepatectomy, n = 10). An miRNA microarray (955 probes) was used to compare the miRNA expression patterns of the non-cancerous liver tissues between the two groups. This study identified the differentially expressed miRNA related to MC recurrence in the liver 上海皓元 remnant. No differences were observed between the two groups in the liver function tests and pathological variables including both tumor factors and non-tumor liver tissues. The investigation selected 20 differentially expressed miRNA related to MC recurrence. Eighteen miRNA were downregulated, while two miRNA were upregulated in the MC group. A hierarchical clustering analysis identified a cluster that may be associated with risk of the MC recurrence of HCC. The MC recurrence-related miRNA included let-7d*, miR-328 and miR18a*, which potentially regulate K-ras gene expression.
