Cells can undergo either cell-cycle arrest or apoptosis after genotoxic stress, based on p53 activity. Here we show that cellular fate commitment depends on Axin forming distinct complexes with Pirh2, Tip60, HIPK2 and p53. In cells treated with sublethal doses of ultra-violet (UV) radiation or doxorubicin (Dox), Pirh2 abrogates Axin-induced p53(More)
p38alpha and p38beta MAPKs (mitogen-activated protein kinases) share about 80% of their protein sequence identity, but have quite different biological functions. One such difference is in regulating the subcellular localization of their downstream kinases, such as PRAK (p38-regulated/activated protein kinase or MK5). The p38alpha-PRAK complex is found in(More)
Echinococcus multilocularis is an important parasite that causes human alveolar echinococcosis. Identification and characterization of the proteins encoded by E. multilocularis metacestode might help to understand the complexity of the parasites and their interactions with the host, and to identify new candidates for immunodiagnosis and vaccine development.(More)
Mitochondrial adenine nucleotide translocase (ANT) is believed to be a component or a regulatory component of the mitochondrial permeability transition pore (mtPTP), which controls mitochondrial permeability transition during apoptosis. However, the role of ANT in apoptosis is still uncertain, because hepatocytes isolated from ANT knockout and wild-type(More)
Axin plays an architectural role in many important signaling pathways that control various aspects of development and tumorigenesis, including the Wnt, transforming growth factor-beta, MAP kinase pathways, as well as p53 activation cascades. It is encoded by the mouse Fused (Fu) locus; the Axin(Fu) allele is caused by insertion of an IAP transposon.(More)
The γ-aminobutyric acid A receptor-associated protein (Gabarap) functions in γ-aminobutyric acid A receptor trafficking and postsynaptic localization in neurons, but its physiological roles in other systems have not been studied. In this study, we report that Gabarap-deficient mice are more susceptible to mortality in two sepsis models. An underlying(More)
The responses of macrophages to Bacillus anthracis infection are important for the survival of the host, since macrophages are required for the germination of B. anthracis spores in lymph nodes, and macrophage death exacerbates anthrax lethal toxin (LeTx)-induced organ collapse. To elucidate the mechanism of macrophage cell death induced by LeTx, we(More)
Tributyltin (TBT), one of the environmental pollutants, has been shown to impact the reproduction of animals. However, due to the lack of appropriate animal model, analysis of the affected molecular pathways in germ cells is lagging and has been particularly challenging. In the present study, we investigated the effects of tributyltin chloride (TBTCL) on(More)
We here describe a convenient method for preparation, fixation and fluorescence analysis of in vitro cultivated metacestode vesicles from E. multilocularis. Parasite materials could be prepared in one hour, did not need to be sectioned, and were subsequently utilized for further whole-mount staining assays directly. Using these preparations, in combination(More)
A new species of cestode, Yorkeria xiamenensis n. sp., is described from the spiral valve of Chiloscyllium plagiosum from coastal waters of Xiamen, China. It is the first record of Yorkeria in China. The new species is distinguished from all other species of Yorkeria by its possession of the following characters: the length of specimens, 15.8 mm; 63-95(More)
