“Embryonic stem (ES) cells or induced pluripotent stem (iPS) cells are expected as a surrogate cell source for regenerative medicine. Many researchers have reported the differentiation method of insulin-expressing pancreatic beta cells from ES or iPS cells. However, the detailed molecular mechanisms underlying the differentiation of ES or iPS cells into pancreatic lineages are still unclear. We have established a feeder cell-based differentiation system into pancreatic progenitor cells, and revealed the signaling pathways that are involved in the differentiation of ES cells into mesendoderm, endoderm and pancreatic progenitor cells. Recently, we demonstrated that the extracellular environment, particularly PF-00299804 purchase the laminin-integrin signaling and heparan sulfate proteoglycan, is important for the regionalization of definitive endoderm cells into pancreatic lineages. These results provide new insights for the differentiation mechanism of pancreatic cell lineages.”
“Hepatitis E virus (HEV) infection is

a common communicable disease in the third world countries. The early diagnosis of HEV is important for the prognosis and prevention of the spread of the disease. Conventional methods for HEV detection need expensive equipment and cannot meet the needs of point of care (POC) use. In the present study, a gold nanoparticle (AuNP) based RT-LAMP assay was developed for colorimetric detection of HEV. As low as 10(1) copies of HEV RNA were detected visually. With

reduced handling and less equipment requirement, this assay provided GSK461364 nmr a simple and rapid alternative to other available methods. (C) 2013 Elsevier B.V. All rights reserved.”
“Mammalian RNF4 is a dimeric RING ubiquitin E3 ligase that ubiquitylates poly-SUMOylated proteins. We found that RNF4 bound ubiquitin-charged UbcH5a tightly but free UbcH5a weakly. To provide insight into the mechanism of RING-mediated ubiquitylation, we docked the UbcH5 similar to ubiquitin thioester onto the RNF4 RING structure. This revealed that with E2 bound to one monomer of RNF4, the thioester-linked ubiquitin could reach across the dimer to engage the other monomer. In this model, the ‘Ile44 hydrophobic patch’ of ubiquitin is predicted to engage a conserved tyrosine located at the dimer interface of the RING, and mutation of these residues blocked ubiquitylation activity. Thus, dimeric RING ligases are not simply inert scaffolds that bring substrate and E2-loaded ubiquitin into close proximity. Instead, they facilitate ubiquitin transfer by preferentially binding the E2 similar to ubiquitin thioester across the dimer and activating the thioester bond for catalysis.”
