The Development of Potential Therapeutic Anti-Myosin S2 Peptides that Modulate Contraction and Append to the Heart Homing Adduct Tannic Acid without Noticeable Effect on Their Functions

Description: This dissertation aimed to explore the S2 region with an attempt to modulate its elasticity in order to tune the contraction output. Two peptides, the stabilizer and destabilizer, showed high potential in modifying the S2 region at the cellular level, thus they were prepared for animal model testing. In this research, (i) S2 elasticity was studied, and the stabilizer and destabilizer peptides were built to tune contraction output through modulating S2 flexibility; (ii) the peptides were attache… more

Studies on the Fibrinolytic Pathway in Zebrafish

Description: Fibrinolysis pathway is an important mechanism for dissolution of fibrin clot by the action of plasmin which is formed from plasminogen, a zymogen via the action of plasminogen activators, i.e. tissue plasminogen activator and urinary plasminogen activator. The regulation of fibrinolysis system in vivo is maintained by plasminogen activators and natural inhibitors i.e. α2-antiplasmin, α2-macroglobulin, Thrombin-activatable fibrinolysis inhibitor (TAFI) and plasminogen activator inhibitor 1 and … more

Quantifying the Effects of Single Nucleotide Changes in the TATA Box of the Cauliflower Mosaic Virus 35S Promoter on Gene Expression in Arabidopsis thaliana

Description: Synthetic biology is a rapidly growing field that aims to treat cellular biological networks in an analogous way to electrical circuits. However, the field of plant synthetic biology has not grown at the same pace as bacterial and yeast synthetic biology, leaving a dearth of characterized tools for the community. Due to the need for tools for the synthetic plant biologist, I have endeavored to create a library of well-characterized TATA box variants in the cauliflower mosaic virus (CaMV) 35S pr… more

Manipulation of Lipid Droplet Biogenesis for Enhanced Lipid Storage in Arabidopsis thaliana and Nicotiana benthamiana

Description: In this study, I examined the use of mouse (Mus musculus) Fat Specific Protein 27 (FSP27) ectopically expressed in Arabidopsis thaliana and Nicotiana benthamiana as a means to increase lipid droplet (LD) presence in plant tissues. In mammalian cells, this protein induces cytoplasmic LD clustering and fusion and helps prevent breakdown of LDs contributing to the large, single LD that dominates adipocytes. When expressed in Arabidopsis thaliana and Nicotiana benthamiana, FSP27 retained its functi… more

Multi-Omics Based Investigation of Distinct Early Oxidative Stress Responses of Saccharomyces cerevisiae to Various Oxidants

Description: The early signaling mechanism(s) that control oxidant perception and signal transduction leading to activation of the antioxidant defense response and survival mechanisms tailored toward specific oxidative insult remains unknown. Here, we identified early changes in metabolome and proteome of S. cerevisiae in response to hydrogen peroxide, menadione, cumene hydroperoxide, and diamide. Firstly, global untargeted LC–MS/MS analysis allowed us to identify 196 proteins in response to hydrogen peroxi… more

Studies on Intrinsic Coagulation Pathway of Zebrafish

Description: In the past couple of decades, the zebrafish has been widely used to study hemostatic disorders. In this study, we generated a CRISPR/Cas9 mediated zebrafish mutant that contains a 55-nucleotide insertion in exon 29 of the von Willebrand factor (vwf) gene. The mutants had impaired ristocetin-mediated agglutination of whole blood, prolonged PTT and more bleeding in the lateral incision compared to wild-type fish. The bleeding phenotype observed here is similar to the phenotype observed in vwf kn… more

Exploring Flavonoid Glycosylation in Kudzu (Pueraria lobata)

Description: The isoflavones in kudzu roots, especially the C-glycosylated isoflavone puerarin, have been linked to many health benefits. Puerarin contains a carbon-carbon glycosidic bond that can withstand hydrolysis. The C-glycosylation reaction in the biosynthesis of puerarin has not been thoroughly investigated, with conflicting reports suggesting that it could take place on daidzein, isoliquiritigenin, or 2,7,4ʹ-trihydroxyisoflavanone. Kudzu species were identified for use in comparative transcriptomic… more

Effect of Phosphorus Starvation on Metabolism and Spatial Distribution of Phosphatidylcholine in Medicago truncatula Wild-Type and PDIL3 Genotypes

Description: Symbiotic nitrogen (N) fixation (SNF) occurs in specialized organs called nodules after successful interactions between legume hosts and rhizobia. Within nodule cells, N-fixing rhizobia are surrounded by plant-derived symbiosome membranes, through which the exchange of nutrients and ammonium occurs between bacteria and the host legume. Phosphorus (P) is an essential macronutrient, and N2-fixing legumes have a higher requirement for P than legumes grown on mineral N. First, I investigated the im… more

Studies on Tissue Factor Pathway Inhibitor in Zebrafish

Description: Tissue Factor Pathway Inhibitor (TFPI) is an anticoagulant protein containing three Kunitz domains, K1, K2 and K3. K1 inhibits Factor VIIa, K2 inhibits Factor Xa, and K3 enhances the Factor Xa inhibition by its interaction with Protein S. Since zebrafish is an excellent genetic model, we hypothesized that TFPI regulation could be studied using this model. As a first step, we confirmed the presence of tfpia in zebrafish. Subsequently, we performed knockdown of tfpia, and knockout of tfpia in K3 … more
