Hedgehog signaling plays conserved roles in controlling embryonic development; its dysregulation has been implicated in many human diseases including cancers. Hedgehog signaling has an unusual reception system consisting of two transmembrane proteins, Patched receptor and Smoothened signal transducer. Although activation of Smoothened and its downstream(More)
Congenital and progressive hearing impairment is a common distressing disease. The progressive dominant hearing loss DFNA28 in human is associated with a frameshift mutation of Grainyhead-like 2 (GRHL2) but its etiology and mechanism remain unknown. Here we report a zebrafish grhl2b(T086) mutant line in which grhl2b expression is interrupted by an insertion(More)
AIMS Tropomyosin (Tpm) proteins, encoded by four Tpm genes (Tpm1-4), are associated with the stabilization of the F-actin filaments and play important roles in modulating muscle contraction. So far, little is known about Tpm4 function in embryonic heart development and its involvement in the cardiovascular diseases. In this study, we investigated functions(More)
The estrogenic compound diethylstilbestrol (DES) has been widely studied to understand its potential involvement in endocrine function and carcinogenesis. This study examined the influence of DES on adult mice by histopathological analysis and studied the gene expression changes using mRNA differential display. Pathological changes in the mice following DES(More)
The Nup107-160 multiprotein subcomplex is essential for the assembly of nuclear pore complexes. The developmental functions of individual constituents of this subcomplex in vertebrates remain elusive. In particular, it is unknown whether Nup107 plays an important role in development of vertebrate embryos. Zebrafish nup107 is maternally expressed and its(More)
High-salt (HS) intake contributes to hypertension and cardiopathy, but the effect of HS on fat deposition is controversial. Feed intake, fat mass, the percentage of abdominal fat, heat production, rate of oxygen consumption and the respiratory exchange ratio of mice on a HS diet were significantly decreased (P < 0.01 or 0.05) compared with mice on a(More)
Phenol oxidase (PO), a copper-containing enzyme with oxygenase activity, can convert mono- or diphenol into quinone and plays an important role in the arthropod melanization reaction. Here, we report a new property of PO from Musca domestica larvae: a thermotolerant endonuclease activity, by which PO can degrade plasmid DNA even after being heated to 80(More)
The degree of adherence to current guidelines for clinical management of ST-segment elevation myocardial infarction (STEMI) is known in developed countries and large Chinese cities, but in predominantly rural areas information is lacking. We assessed the application of early reperfusion therapy for STEMI in secondary and tertiary hospitals in Henan province(More)
Net1 is a well-characterized oncoprotein with RhoA-specific GEF activity. Oncogenic Net1, which lacks the first 145 amino acids, is present in the cytosol and contributes to the efficient activation of RhoA and the formation of actin stress fibers in a number of tumor cell types. Meanwhile, wild-type Net1 is predominantly localized in the nucleus at steady(More)
