Cardiotrophin-1 is an anti-inflammatory cytokine and promotes IL-4-induced M2 macrophage polarization.

Macrophages play a central role in tissue remodeling, repair, and resolution of inflammation. Macrophage polarization to M1 or M2 activation status may determine the progression or resolution of the inflammatory response. We have previously reported that cardiotrophin-1 (CT-1) displays both cytoprotective and metabolic activities.

Strict requirement for vector-induced type I interferon in efficacious antitumor responses to virally encoded IL12.

Host responses are increasingly considered important for the efficacious response to experimental cancer therapies that employ viral vectors, but little is known about the specific nature of host responses required. In this study, we investigated the role of host type I interferons (IFN-I) in the efficacy of virally delivered therapeutic genes. Specifically, we used a Semliki Forest virus encoding IL12 (SFV-IL12) based on its promise as an RNA viral vector for cancer treatment.

Zolmitriptan: a novel portal hypotensive agent which synergizes with propranolol in lowering portal pressure.

Objective: Only a limited proportion of patients needing pharmacological control of portal hypertension are hemodynamic responders to propranolol. Here we analyzed the effects of zolmitriptan on portal pressure and its potential interaction with propranolol.

Methods: ZOLMITRIPTAN, PROPRANOLOL OR BOTH WERE TESTED IN TWO RAT MODELS OF PORTAL HYPERTENSION: common bile duct ligation (CBDL) and CCl4-induced cirrhosis.

Transcriptomic effects of Tet-on and mifepristone-inducible systems in mouse liver.

Control of transgene expression from long-term expression vectors can be achieved with inducible and regulated promoters. The two most commonly used inducible systems employ doxycycline or mifepristone as the drug activating a silent trans-activator, which is expressed from a constitutive promoter. We evaluated the alterations provoked by constitutive expression in the liver of rtTA2(S)-M2 (rtTA2; second-generation reverse tetracycline-controlled trans-activator) and GLp65, which are the trans-activators of the doxycyline- and mifepristone-inducible systems, respectively.

Human cytomegalovirus proteins encoded by UL37 exon 1 protect infected fibroblasts against virus-induced apoptosis and are required for efficient virus replication.

Human cytomegalovirus (HCMV) strain AD169 mutants carrying transposon insertions or large deletions in UL37 exon 1 (UL37x1) were recovered from modified bacterial artificial chromosomes by reconstitution in human fibroblasts expressing the adenovirus anti-apoptotic protein E1B19K. UL37x1 mutant growth was severely compromised in normal fibroblasts, with minimal release of infectious progeny. Growth in E1B19K-expressing cells was restored, but did not reach wild-type levels.
