Peste des petits ruminants virus (PPRV) causes an acute and highly contagious disease in domestic and wild small ruminants throughout the world, mainly by invoking immunosuppression in its natural hosts. It has been suggested that the non-structural C protein of PPRV helps in evading host responses but the molecular mechanisms by which it antagonizes the host responses have not been fully characterized. Here, we report the antagonistic effect of PPRV C protein on the expression of interferon-β (IFN-β) through both MAVS and RIG-I mediated pathways in vitro. Dual luciferase reporter assay and direct expression of IFN-β mRNA analysis indicated that PPRV C significantly down regulates IFN-β via its potential interaction with MAVS and RIG-I signaling molecules. Results further indicated that PPRV C protein significantly suppresses endogenous and exogenous IFN-β-induced anti-viral effects in PPRV, EMCV and SVS infections in vitro. Moreover, PPRV C protein not only down regulates IFN-β but also the downstream cytokines of interferon stimulated genes 56 (ISG56), ISG15, C-X-C motif chemokine (CXCL10) and RIG-I mediated activation of IFN promoter elements of ISRE and NF-κB. Further, this study deciphers that PPRV C protein could significantly inhibit the phosphorylation of STAT1 and interferes with the signal transmission in JAK-STAT signaling pathway. Collectively, this study indicates that PPRV C protein is important for innate immune evasion and disease progression.Porcine circovirus type 2 (PCV2) is the primary agent responsible for porcine circovirus-associated diseases (PCVADs), which is acknowledged as one of the most economically important diseases for the swine industry worldwide. Currently, the development of PCV2 vaccine against PCVADs and for other applications require large amounts of viral particles. The low propagation rate of PCV2 in vitro limits vaccine production. Previous studies showed that a cell line transfected with the porcine interleukin (IL)-2 gene gave higher PCV2 yield in vitro. However, transient transfection may become less effective and unstable after serial generations. In this work, we constructed a PK15 cell line with stable expression of porcine IL2 by lentivirus transfection. The results demonstrated that the transgenic cell line stably expressed IL2 protein significantly enhanced PCV2 replication. Thus, the transgenic PK15 cell line could be a promising cell line for vaccine production.Sorafenib is one of the multi-targeted tyrosine kinase inhibitors (TKI), mainly used for treating advanced renal cell carcinoma.  https://www.selleckchem.com/products/s64315-mik665.html  Accumulated evidence indicates a minority of patients develop nephrotic syndrome (NS) as a high-grade nephrotoxic injury; however, evidence of NS after long-term use of sorafenib remains unclear. A 64-year-old man developed NS following 2-year use of sorafenib and his NS persisted even after sorafenib use was discontinued. Renal biopsy disclosed minimal change disease (MCD) concurrent with acute tubulointerstitial nephritis, indicating secondary MCD with which sorafenib may be involved. To prevent permanent renal insufficiency, we administered glucocorticoid and succeeded in achieving complete remission from NS. Nephrotoxic injuries could occur at any time with variable onset after sorafenib. Renal biopsy should be pursued in the case of NS associated with TKI therapy. To facilitate recovery of renal dysfunction, administration of prednisolone should be considered, particularly when NS does not disappear after cessation of TKIs.Despite of the increasing number of investigations on the effects of acute exercise on circulating stem and progenitor cell (SC) numbers, and in particular on respective subgroups, i.e. endothelial (ESC), hematopoietic (HSC), and mesenchymal (MSC) stem and progenitor cells, a consensus regarding mechanisms and extent of these effects is still missing. The aim of this meta-analysis was to systematically evaluate the overall-effects of acute exercise on the different SC-subgroups and investigate possible subject- and intervention-dependent factors affecting the extent of SC-mobilization in healthy humans. Trials assessing SC numbers before and at least one timepoint after acute exercise, were identified in a systematic computerized search. Compared to baseline, numbers were significantly increased for early and non-specified SCs (enSCs) until up to 0.5 h after exercise (0-5 min +0.64 [Standardized difference in means], p  less then  0.001; 6-20 min +0.42, p  less then  0.001; 0.5 h +0.29, p = 0.049), for ESCs until 12-48 h after exercise (0-5 min +0.66, p  less then  0.001; 6-20 min +0.43 p  less then  0.001; 0.5 h +0.43, p = 0.002; 1 h +0.58, p = 0.001; 2 h +0.50, p = 0.002; 3-8 h +0.70, p  less then  0.001; 12-48 h +0.38, p = 0.003) and for HSCs at 0-5 min (+ 0.47, p  less then  0.001) and at 3 h after exercise (+ 0.68, p  less then  0.001). Sex, intensity and duration of the intervention had generally no influence. The extent and kinetics of the exercise-induced mobilization of SCs differ between SC-subpopulations. However, also definitions of SC-subpopulations are non-uniform. Therefore, finding a consensus with a clear definition of cell surface markers defining ESCs, HSCs and MSCs is a first prerequisite for understanding this important topic.OCT4 plays critical roles in self-renewal and pluripotency maintenance of embryonic stem cells, and is considered as one of the main stemness markers. It also has pivotal roles in early stages of embryonic development. Most studies on OCT4 have focused on the expression and function of OCT4A, which is the biggest isoform of OCT4 known so far. Recently, many studies have shown that OCT4 has various transcript variants, protein isoforms, as well as pseudogenes. Distinguishing the expression and function of these variants and isoforms is a big challenge in expression profiling studies of OCT4. Understanding how OCT4 is functioning in different contexts, depends on knowing of where and when each of OCT4 transcripts, isoforms and pseudogenes are expressed. Here, we review OCT4 known transcripts, isoforms and pseudogenes, as well as its interactions with other proteins, and emphasize the importance of discriminating each of them in order to understand the exact function of OCT4 in stem cells, normal development and development of diseases.
