Structural And Biochemical Studies Of The Dna Replication Initiation Mechanism Of The Second Chromosome Of Vibrio Cholerae, Natalia Orlova
Structural And Biochemical Studies Of The Dna Replication Initiation Mechanism Of The Second Chromosome Of Vibrio Cholerae, Natalia Orlova
Dissertations, Theses, and Capstone Projects
Transmission of genetic information through DNA replication is one of the key processes for any living organism. Despite the extensive effort put into studies of the mechanism of DNA replication, the understanding of the process on the molecular level is still incomplete. Specifically the molecular details of the very first events of DNA replication initiation are not sufficiently understood.
The majority of bacteria possess a single circular chromosome, and in order to initiate DNA replication these organisms utilize a conserved system, consisting of a specific DNA sequence - replication origin, called oriC, and replication initiator protein DnaA. However, bacteria …

Pharmacological Antagonism And The Olfactory Code, Mihwa Na

Mammals can detect and discriminate uncountable odors through their odorant receptors. To accommodate the countless and diverse odors, exceptionally large numbers of odorant receptor (OR) genes are expressed in mammals. In addition, the mammals utilize a combinatorial code, where an odorant molecule can activate multiple ORs; an OR also responds to a set of multiple odorants. In nature, an odor is often a complex mixture of multiple odorant molecules. The combination of the ORs activated by each constituent generates the unique olfactory code for the particular odor.
Some odorants can antagonize select ORs, as discussed in Chapter 1. An antagonist …
Mutagenesis Of Human Alpha-Galactosidase A For The Treatment Of Fabry Disease, Erin Stokes
Mutagenesis Of Human Alpha-Galactosidase A For The Treatment Of Fabry Disease, Erin Stokes
Dissertations, Theses, and Capstone Projects
Fabry disease is an X-linked lysosomal storage disorder caused by the deficiency of the enzyme, α-galactosidase A, which results in the accumulation of the lipid substrate. This accumulation results in obstruction of blood flow in patients and early demise at approximately 40-60 years of age. There is currently only one FDA approved treatment (Fabrazyme) classified as an enzyme replacement therapy. However, approximately 88% of patients experience a severe immune response that, rarely, can be fatal and is a huge cost burden at average $250,000 a year per patient. The structure of α-galactosidase A has been previously determined to be a …
Insight Into The Interaction Between The Peroxisome Proliferator-Activated Receptor Gamma (Pparγ) And Adipocyte Fatty Acid-Binding Protein (A-Fabp), Qian Wang
Dissertations, Theses, and Capstone Projects
The Adipocyte Fatty Acid-Binding Protein (AFABP) is mainly expressed in fat cells. It can bind fatty acids and other lipophilic substances such as eicosanoids and retinoids. The peroxisome proliferator-activated receptor γ (PPARγ) is a nuclear receptor protein that requires ligand binding to regulate the specific gene transcription. PPARγ is expressed at extremely high levels in adipose tissue, macrophages, and the large intestine, where it controls lipid adipogenesis and energy conversion. Moreover, it has been found that AFABP and PPARγ can form a complex in vivo. It is proposed that AFABP carries the ligand and enters into the nucleus where it …

A Combined Computational Strategy Of Sequence And Structural Analysis Predicts The Existence Of A Functional Eicosanoid Pathway In Drosophila Melanogaster, Michael Scarpati
Dissertations, Theses, and Capstone Projects
With increased understanding of their roles in signal transduction and metabolism, eicosanoids have emerged as important players in human health and disease. Mammalian prostanoids and related lipid mediators perform varied functions in different tissues and organs. Synthesized through the oxygenation of C20 polyunsaturated fatty acids, mammalian eicosanoids are both pro- and anti-inflammatory. The physiological contexts in which eicosanoid family members act at the cellular level are not well understood. In this study, we examined whether the genome of Drosophila melanogaster, a powerful model for innate immunity and inflammation, codes for the enzymes required for eicosanoid biosynthesis. We report the …
Transcriptional And Post-Transcriptional Regulation Of Histone Variant H2a.Z During Sea Urchin Development, Mihai Hajdu
Transcriptional And Post-Transcriptional Regulation Of Histone Variant H2a.Z During Sea Urchin Development, Mihai Hajdu
Dissertations, Theses, and Capstone Projects
Histone variant H2A.Z promotes chromatin accessibility at transcriptional regulatory elements and is developmentally regulated in metazoans. We characterize the transcriptional and post-transcriptional regulation of H2A.Z in the purple sea urchin Strongylocentrotus purpuratus. H2A.Z depletion by antisense translation-blocking morpholino oligonucleotides during early development causes developmental collapse, in agreement with its previously demonstrated general role in transcriptional multipotency. During H2A.Z peak expression in 24-h embryos, endogenous H2A.Z 3’ UTR sequences stabilize GFP mRNAs relative to those with SV40 3’ UTR sequences, although the 3’UTR of H2A.Z does not determine the spatial distribution of H2A.Z transcripts during embryonic and postembryonic development. We …
