WD40 repeat proteins play important roles in a variety of cellular functions, including cell growth, proliferation, apoptosis, and intracellular signal transduction. Mitogen-activated protein kinases (MAPKs) are evolutionary conserved enzymes in cell signal transduction connecting cell-surface receptors to critical regulatory targets within cells and(More)
Cardiac valves serve an important function; they support unidirectional blood flow and prevent blood regurgitation. Wnt signaling plays an important role in the formation of mouse cardiac valves and cardiac valve proliferation in Zebrafish, but identification of the specific signaling components involved has not been addressed systematically. Of the(More)
Kisspeptins are natural ligands of G protein-coupled receptor-54. Activation of KiSS1/G protein-coupled receptor-54 signaling pathways results in potent activation of the hypothalamus-pituitary-gonadal axis and initiates puberty. Recent data have shown that in female mice, KiSS1 is positively regulated by estradiol (E(2)) in the anteroventral(More)
The Drosophila heart has proven itself to be an excellent model for human cardiac development and recent investigations suggest that it may serve as a model for human heart function as well. Just as tinman-related genes underlie cardiac development in all organisms with a heart, the functional properties of mature hearts also appear to be conserved in the(More)
It has been reported that mouse Lbh (limb-bud and heart) can regulate cardiac gene expression by modulating the combinatorial activities of key cardiac transcription factors, as well as their individual functions in cardiogenesis. Here we report the cloning and characterization of the human homolog of mouse Lbh gene, hLBH, from a human embryonic heart cDNA(More)
BACKGROUND Recent studies have demonstrated that myocardial calpain triggers caspase-3 activation and myocardial apoptosis in models of sepsis, whereas the inhibition of calpain activity down-regulates myocardial caspase-3 activation and apoptosis. However, the mechanism underlying this pathological process is unclear. Therefore, in this study, our aim was(More)
The Bric-a-brac, Tramtrack, Broad-complex (BTB) domain is a protein-protein interaction domain that is found in many zinc finger transcription factors. BTB containing proteins play important roles in a variety of cellular functions including regulation of transcription, regulation of the cytoskeleton, protein ubiquitination, angiogenesis, and apoptosis.(More)
Mitogen-activated protein kinases (MAPKs) are evolutionarily conserved enzymes in cell signal transduction. Previous studies revealed that zinc finger proteins are involved in the regulation of the MAPK signaling pathways. Here we report the identification and characterization of a novel human zinc finger protein, ZNF540. The cDNA of ZNF540 is 3.3kb,(More)
Zinc finger transcription factors are involved broadly in development and tumorigenesis. Here, we report that the little studied zinc finger transcription factor ZNF382 functions as a tumor suppressor in multiple carcinomas. Although broadly expressed in normal tissues, ZNF382 expression was attenuated in multiple carcinoma cell lines due to promoter CpG(More)
Camurati-Engelmann disease (CED) [OMIM 131300] is a rare autosomal dominant disorder characterized by bone pain and osteosclerosis affecting the diaphysis of long bones. It has been previously reported that CED is caused by mutations of the transforming growth factor beta 1 (TGF beta1) gene on chromosome 19q13.1-q13.3. Until now, seven mutations(More)
