Multiple Kh Domains Of Poly C Binding Protein Are Required For Its Trans-Activation On The Proximal Promoter Of The Mu-Opioid Receptor Gene, Adnan K. Malik

Seton Hall University Dissertations and Theses (ETDs)

The mu-opioid receptor (MOR) has been shown to mediate morphine induced analgesia, addiction, and tolerance. The expression of the major product of the MOR (MOR-1) gene has been found to be driven by two promoters, a distal promoter and a proximal promoter. The proximal promoter region has been shown in previous studies to be the major promoter for the regulation of MOR gene transcription in the adult mouse brain and embryonic development. Recent studies have shown that single-stranded DNA binding proteins (such as Poly C Binding Protein) are involved in transcriptional regulation of mouse MOR gene. Poly C binding protein …

Chemical Genomics In Yeast, Charles Brenner

Dartmouth Scholarship

Four recent 'chemical genomic' studies, using genome-scale collections of yeast gene deletions, have presented complementary approaches to identifying gene-drug and pathway-drug interactions.Many drugs have unknown, controversial or multiple mechanisms of action. Four recent 'chemical genomic' studies, using genome-scale collections of yeast gene deletions that were either arrayed or barcoded, have presented complementary approaches to identifying gene-drug and pathway-drug interactions.

Chloroplast Dna Rearrangements In Campanulaceae: Phylogenetic Utility Of Highly Rearranged Genomes, Mary E. Cosner, Linda A. Raubeson, Robert K. Jansen

All Faculty Scholarship for the College of the Sciences

Background

The Campanulaceae (the "hare bell" or "bellflower" family) is a derived angiosperm family comprised of about 600 species treated in 35 to 55 genera. Taxonomic treatments vary widely and little phylogenetic work has been done in the family. Gene order in the chloroplast genome usually varies little among vascular plants. However, chloroplast genomes of Campanulaceae represent an exception and phylogenetic analyses solely based on chloroplast rearrangement characters support a reasonably well-resolved tree.

Results

Chloroplast DNA physical maps were constructed for eighteen representatives of the family. So many gene order changes have occurred among the genomes that characterizing individual mutational …

A Role For Tbx5 In Proepicardial Cell Migration During Cardiogenesis, Cathy J. Hatcher, Nata Diman, Minsu Kim, David Pennisi, Yan Song, Marsha M. Goldstien, Takashi Mikawa, Craig T. Basson

PCOM Scholarly Works

Transcriptional regulatory cascades during epicardial and coronary vascular development from proepicardial progenitor cells remain to be defined. We have used immunohistochemistry of human embryonic tissues to demonstrate that the TBX5 transcription factor is expressed not only in the myocardium, but also throughout the embryonic epicardium and coronary vasculature. TBX5 is not expressed in other human fetal vascular beds. Furthermore, immunohistochemical analyses of human embryonic tissues reveals that unlike their epicardial counterparts, delaminating epicardial-derived cells do not express TBX5 as they migrate through the subepicardium before undergoing epithelial-mesenchymal transformation required for coronary vasculogenesis. In the chick, Tbx5 is expressed in the …
