In the obesity-resistant SJL mouse strain, we previously identified a naturally occurring loss-of-function mutation in the gene for Tbc1d1. Characterization of recombinant inbred mice that carried the Tbc1d1(SJL) allele on a C57BL/6J background indicated that loss of TBC1D1 protects from obesity, presumably by increasing the use of fat as energy source.

Krüppel-like factors (Klf) 4 and 5 are two closely related members of the Klf family, known to play key roles in cell cycle regulation, somatic cell reprogramming and pluripotency. Here we focus on the functional divergence between Klf4 and Klf5 in the inhibition of mouse embryonic stem (ES) cell differentiation. Using microarrays and chromatin(More)
The glycoprotein G of lyssaviruses is the major determinant of virus pathogenicity and serves as a target for immunological responses to virus infections. However, assessment of the exact contribution of lyssavirus G proteins to observed differences in the pathogenicity of lyssavirus species is challenging, since the direct comparison of natural(More)
1-Methylpyrene, a carcinogenic polycyclic aromatic hydrocarbon, forms benzylic DNA adducts, in particular N2-(1-methylpyrenyl)-2'-deoxyguanosine, in mice and rats. It is bioactivated via 1-hydroxymethylpyrene (1-HMP) to electrophilic 1-sulfooxymethylpyrene (1-SMP). In this study, we explored the role of individual mouse sulfotransferase (SULT) forms in this(More)
Methyleugenol--a natural constituent of herbs and spices--is hepatocarcinogenic in rodent models. It can form DNA adducts after side-chain hydroxylation and sulfation. We previously demonstrated that human sulfotransferases (SULTs) 1A1 and 1A2 as well as mouse Sult1a1, expressed in Salmonella target strains, are able to activate 1'-hydroxymethyleugenol(More)
UNLABELLED Rabies virus (RABV) spread is widely accepted to occur only by retrograde axonal transport. However, examples of anterograde RABV spread in peripheral neurons such as dorsal root ganglion (DRG) neurons indicated a possible bidirectional transport by an uncharacterized mechanism. Here, we analyzed the axonal transport of fluorescence-labeled RABV(More)
Bokeloh bat lyssavirus (BBLV), a novel lyssavirus, was isolated from a Natterer's bat (Myotis nattererii), a chiropteran species with a widespread and abundant distribution across Europe. As a novel lyssavirus, the risks of BBLV to animal and human health are unknown and as such characterization both in vitro and in vivo was required to assess pathogenicity(More)
Brachyury(+) mesodermal cell population with purity over 79% was obtained from differentiating brachyury embryonic stem cells (ESC) generated with brachyury promoter driven enhanced green fluorescent protein and puromycin-N-acetyltransferase. A comprehensive transcriptomic analysis of brachyury(+) cells enriched with puromycin application from 6-day-old(More)
Cell volume alteration represents an important factor contributing to the pathology of late-onset diseases. Previously, it was reported that protein biosynthesis and degradation are inversely (trans) regulated during cell volume regulation. Upon cell shrinkage, protein biosynthesis was up-regulated and protein degradation down-regulated. Cell swelling(More)
Ojoplano (Opo) is a morphogenetic gene playing an important role during embryogenesis in medaka. This report focuses on the identification and characterization of the mouse Opo gene. We examined Opo expression by whole-mount in situ hybridization and in situ hybridization on sagittal sections during mouse embryogenesis. First expression in whole-mounts was(More)
