Sp1-like zinc finger transcription factors are involved in the regulation of cell growth and differentiation. Recent evidence demonstrating that mammalian cells express novel, yet uncharacterized, Sp1-like proteins has stimulated a search for new members of this family. We and others have recently reported that the transforming growth factor(More)
Dynamin proteins are members of a recently described family of GTPases involved in receptor-mediated processes. To date, three different dynamin-encoding genes have been identified in mammalian tissues. Dynamin I is expressed only in neurons, whereas dynamin II is ubiquitously expressed. A third isoform, dynamin III, was originally isolated from a rat(More)
Members of the dynamin superfamily are GTPases which have been shown to support receptor-mediated endocytosis in vivo and bind to growth factor receptor-associated proteins in vitro. In acinar cells of the pancreas, receptor-mediated endocytosis is very important for the recycling of membranes after secretory granule release. Therefore, characterization of(More)
Sp1-like transcription factors are characterized by three highly homologous C-terminal zinc finger motifs that bind GC-rich sequences. These proteins behave as either activators or repressors and have begun to be classified into different subfamilies based upon the presence of conserved motifs outside the zinc finger domain. This classification predicts(More)
Genes encoding for C2H2 zinc finger proteins are known to regulate normal cell proliferation and differentiation and have often been found to be mutated in different forms of cancer. We are interested in understanding the role of these genes as regulators of cell proliferation and differentiation in the exocrine pancreas. Therefore, we have generated(More)
The authors conducted a survey of dentists reporting tooth avulsions from basketball net accidents. Although the number of people injured was small, the dental injuries were serious. In many cases, multiple teeth were avulsed as a result of the maxillary anterior teeth becoming entangled in the basketball net while the patients were attempting to slamdunk a(More)
vast amount of figures and illustrations are included , which highlight historical aspects of fMRI, as well as the physics and the psychological principles behind this imaging technique. Patient-derived images provide relevant examples and further convey the ideas presented throughout the text. Questions presented throughout the book engage the reader and(More)
Zinc finger transcription factors are DNA-binding proteins that are known to determine the identity of cells by regulating cell-specific gene expression. In addition, mutations in some members of this family have been found to be associated with several neoplasias, including Wilms' tumor and leukemias. Because the mechanisms that regulate normal, as well as(More)
