Structural And Functional Evaluation Of C. Elegans Filamins Fln-1 And Fln-2, Christina DeMaso, Ismar Kovacevic, Alper Uzun, Erin Cram 2011 Northeastern University

Structural And Functional Evaluation Of C. Elegans Filamins Fln-1 And Fln-2, Christina Demaso, Ismar Kovacevic, Alper Uzun, Erin Cram

Erin Cram

Filamins are long, flexible, multi-domain proteins composed of an N-terminal actin-binding domain (ABD) followed by multiple immunoglobulin-like repeats (IgFLN). They function to organize and maintain the actin cytoskeleton, to provide scaffolds for signaling components, and to act as mechanical force sensors. In this study, we used transcript sequencing and homology modeling to characterize the gene and protein structures of the C. elegans filamin orthologs fln-1 and fln-2. Our results reveal that C. elegans FLN-1 is well conserved at the sequence level to vertebrate filamins, particularly in the ABD and several key IgFLN repeats. Both FLN-1 and the more divergent FLN-2 ...

Non-Viral Enos Gene Delivery And Transfection With Stents For The Treatment Of Restenosis, Luis Brito, Saradha Chandrasekhar, Steven Little, Mansoor Amiji

Mansoor M. Amiji

Background In this study, we have examined local non-viral gene delivery, transfection, and therapeutic efficacy of endothelial nitric oxide synthase (eNOS) encoding plasmid DNA administered using coated stents in a rabbit iliac artery restenosis model. Methods Lipopolyplexes (LPPs) with eNOS expressing plasmid DNA were immobilized on stainless steel stents using poly(D,L-lactide-co-glycolide) (PLGA) and type B gelatin coatings. The gene-eluting stents were implanted bilaterally in the denuded iliac arteries and eNOS transfection and therapeutic efficacy were examined 14 days after implantation. Results The results show that non-viral lipopolyplex-coated stents can efficiently tranfect eNOS locally in the arterial lumen assessed ...


Role Of Hypoxia And Glycolysis In The Development Of Multi-Drug Resistance In Human Tumor Cells And The Establishment Of An Orthotopic Multi-Drug Resistant Tumor Model In Nude Mice Using Hypoxic Pre-Conditioning, Lara Milane, Zhenfeng Duan, Mansoor Amiji 2011 Northeastern University

Role Of Hypoxia And Glycolysis In The Development Of Multi-Drug Resistance In Human Tumor Cells And The Establishment Of An Orthotopic Multi-Drug Resistant Tumor Model In Nude Mice Using Hypoxic Pre-Conditioning, Lara Milane, Zhenfeng Duan, Mansoor Amiji

Mansoor M. Amiji

Background The development of multi-drug resistant (MDR) cancer is a significant challenge in the clinical treatment of recurrent disease. Hypoxia is an environmental selection pressure that contributes to the development of MDR. Many cancer cells, including MDR cells, resort to glycolysis for energy acquisition. This study aimed to explore the relationship between hypoxia, glycolysis, and MDR in a panel of human breast and ovarian cancer cells. A second aim of this study was to develop an orthotopic animal model of MDR breast cancer. Methods Nucleic and basal protein was extracted from a panel of human breast and ovarian cancer cells ...

A Strawberry Knox Gene Regulates Leaf, Flower And Meristem Architecture, Mithu Chatterjee, Claudia L. Bermudez-Lozano, Maureen A. Clancy, Thomas M. Davis, Kevin M. Folta

Biological Sciences Scholarship

The KNOTTED-LIKE HOMEODOMAIN (KNOX) genes play a central role in maintenance of the shoot apical meristem. They also contribute to the morphology of simple and compound leaves. In this report we characterize the FaKNOX1 gene from strawberry (Fragaria spp.) and demonstrate its function in trasgenic plants. The FaKNOX1 cDNA was isolated from a cultivated strawberry (F.×ananassa) flower EST library. The sequence is most similar to Class I KNOX genes, and was mapped to linkage group VI of the diploid strawberry genome. Unlike most KNOX genes studied, steady-state transcript levels were highest in flowers and fruits. Transcripts were also detected ...

Critical Stages In Viral Replication - Entry, Gene Regulation And Egress, Matthew S. Miller 2011 The University of Western Ontario

Critical Stages In Viral Replication - Entry, Gene Regulation And Egress, Matthew S. Miller

Electronic Thesis and Dissertation Repository

Despite the amazing biological diversity exhibited by viruses, their very existence relies upon their ability to overcome a set of common barriers. The nature of these barriers reflects the nature of viruses themselves. During their extracellular phase, viruses are metabolically inert obligate parasites. Upon encountering a host cell, productive infection necessitates that the virus successfully enter the cell, regulate the expression of its genes, and after assembling new progeny particles, egress such that the cycle of infection can continue. These three basic processes are not only attractive candidates for therapeutic intervention, but also reveal much about virus biology in the ...

Sanders-Brown Center on Aging Faculty Publications

While research supports amyloid-β (Aβ) as the etiologic agent of Alzheimer's disease (AD), the mechanism of action remains unclear. Evidence indicates that adducts of RNA caused by oxidation also represent an early phenomenon in AD. It is currently unknown what type of influence these two observations have on each other, if any. We quantified five RNA adducts by gas chromatography/mass spectroscopy across five brain regions from AD cases and age-matched controls. We then used a reductive directed analysis to compare the RNA adducts to common indices of AD neuropathology and various pools of Aβ. Using data from four ...

Seed Production In Weedy Setaria Spp.-Gp, M. J. Haar, Jack H. Dekker

Agronomy Publications

Seeds from Setaria faberi, S. viridis and S. pumila panicles in three Iowa crop fields were collected for the entire reproductive period. Seed number, panicle length, and seed number per panicle length varied among species, panicle types and sites. Greater numbers of seed per plant and per panicle were observed than previously reported. Setaria seed rain exhibited some stable, and many more plastic, responses. S. faberi panicles were consistently longer than those of S. viridis. S. viridis parameters were greater than S. pumila. Earlier panicles were greater than, or similar to, later ones for all parameters. More typically, tillers and ...

Corn, Brianne Sherwood, Amanda Hawks 2011 Utah State University

Corn, Brianne Sherwood, Amanda Hawks

USU Student Organic Farm Newsletter

We have so much corn right now it's coming out of our ears (great pun, right?). And it's SO incredibly cheap! This is probably because the US produces 42% of the world's corn! Most of it is used for animal feed, but other uses include exporting to other countries, human food, seed, and industrial uses such as ethanol production. Because there is so much corn available here in the U.S. You can find it in a lot more foods than you think. It's in peanut butter, snack foods, soft drinks, multivitamins, ketchup, mustard, ground beef ...

Characterization Of Hpk2-Rrp2, Two-Component Regulatory System In Treponema Denticola, Sarkar Juni 2011 Virginia Commonwealth University

Characterization Of Hpk2-Rrp2, Two-Component Regulatory System In Treponema Denticola, Sarkar Juni

Theses and Dissertations

Treponema denticola levels in the gingival crevice become elevated as periodontal disease develops. Oral treponemes may account for as much as 40% of the total bacterial population in the periodontal pocket. The stimuli that trigger enhanced growth of T. denticola and the mechanisms associated with the transmission of these signals remain to be defined. A hypothesis was set that the T. denticola ORFs tde1970 (histidine kinase) and tde1969 (response regulator) constitute a functional two component regulatory system that regulates, at least in part, responses to the changing environmental conditions associated with the development of periodontal disease. The results presented demonstrate ...

Coaching Power Tool: Success Vs. Failure, Connie I. Reimers-Hild

Kimmel Education and Research Center - Faculty & Staff Publications

Part of personal leadership and innovation is self-discovery, which requires introspection and the ability to see the unseen. Sometimes it is necessary to consider a different perspective. We have to shift our thinking to see possibilities in a new light. Sometimes, it is the unobvious that may be the most important. It is important for us to challenge our thinking and traditional thought to redefine success, failure and our ability to take risks.
