Chlorella Viruses Encode Most, If Not All, Of The Machinery To Glycosylate Their Glycoproteins Independent Of The Endoplasmic Reticulum And Golgi, James L. Van Etten, James Gurnon, Giane M. Yanai-Balser, David Dunigan, Michael V. Graves

Nebraska Center for Virology: Faculty Publications

In contrast to all other viruses that use the host machinery located in the endoplasmic reticulum and Golgi to glycosylate their glycoproteins, the large dsDNA-containing chlorella viruses encode most, if not all, of the components to glycosylate their major capsid proteins. Furthermore, all experimental results indicate that glycosylation occurs independent of the endoplasmic reticulum and Golgi. (Review article)

Loss Of The Sin3 Transcriptional Corepressor Results In Aberrant Mitochondrial Function, Valerie L. Barnes, Bethany S. Strunk, Icksoo Lee, Maik Hüttemann, Lori A. Pile

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

SIN3 is a transcriptional repressor protein known to regulate many genes, including a number of those that encode mitochondrial components.

Results

By monitoring RNA levels, we find that loss of SIN3 inDrosophilacultured cells results in up-regulation of not only nuclear encoded mitochondrial genes, but also those encoded by the mitochondrial genome. The up-regulation of gene expression is accompanied by a perturbation in ATP levels in SIN3-deficient cells, suggesting that the changes in mitochondrial gene expression result in altered mitochondrial activity. In support of the hypothesis that SIN3 is necessary for normal mitochondrial function, yeastsin3null mutants exhibit very poor …

Cellular And Molecular Dissection Of Pluripotent Adult Somatic Stem Cells In Planarians, Norito Shibata, Labib Rouhana, Kiyokazu Agata

Biological Sciences Faculty Publications

Freshwater planarians, Plathelminthes, have been an intriguing model animal of regeneration studies for more than 100 years. Their robust regenerative ability is one of asexual reproductive capacity, in which complete animals develop from tiny body fragments within a week. Pluripotent adult somatic stem cells, called neoblasts, assure this regenerative ability. Neoblasts give rise to not only all types of somatic cells, but also germline cells. During the last decade, several experimental techniques for the analysis of planarian neoblasts at the molecular level, such as in situ hybridization, RNAi and fluorescence activated cell sorting, have been established. Moreover, information about genes …

Functional Characterization Of Nuclear Receptor And Co-Activator Binding Loci In The Human Genome, Kim Maguire

Masters

Steroid hormones, such as oestrogen, mediate their effects via activation of oestrogen regulated genes using nuclear receptors. Selective oestrogen receptor modulators (SERMs), such as Tamoxifen, are used to treat oestrogen responsive breast cancers, hctioning to act as oestrogen antagonists, preventing the oestrogen receptor biding DNA and blocking gene expression. However, Tamoxifen has been identified as an oestrogen agonist in other tissues which can often lead to secondary tumors in the years following the treatment. Identification of the genomic regions where SERMs can act as oestrogen agonists can possibly lead to the development of gene targeted therapies or other alternatives to …

Patterned Cell Cultures For High Throughput Studies Of Cell Electrophysiology And Drug Screening Applications, Anupama Natarajan

Electronic Theses and Dissertations

Over the last decade, the field of tissue and bio-engineering has seen an increase in the development of in vitro high-throughput hybrid systems that can be used to understand cell function and behavior at the cellular and tissue levels. These tools would have a wide array of applications including for implants, drug discovery, and toxicology, as well as for studying cell developmental behavior and as disease models. Currently, there are a limited number of efficient, functional drug screening assays in the pharmacology industry and studies of cell-surface interactions are complicated and invasive. Most cell physiology studies are performed using conventional …

Studies On A Novel Human Cardiospecific Transcription Factor And Its Involvement In Omi/Htra2 Mediated Cell Death, Meenakshi Puthucode Balakrishnan

Electronic Theses and Dissertations

Omi/HtrA2 is a mitochondrial serine protease that is known to translocate to the cytoplasm upon induction of apoptosis and to activate caspase-dependent and caspase-independent cell death. The molecular mechanism of Omi/HtrA2's function is not clear but involves degradation of specific substrates. These substrates include cytoplasmic, mitochondrial, as well as nuclear proteins. We have isolated a new Omi/HtrA2 interactor, the THAP5 protein. THAP5 is a fifth member of a large family of transcription factors that are involved in cell proliferation, apoptosis, cell cycle control, chromosome segregation, chromatin modification and transcriptional regulation. THAP5 is an approximately 50kDa nuclear protein, with a restricted …
