Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)
Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)
Electronic Theses and Dissertations
The observed overlap between genetic variants associated with both adiposity and inflammatory markers suggests that changes in both adiposity and inflammation could be partially mediated by common pathways. The pervasive but sparsely characterized “pleiotropic” genetic variants associated with both adiposity and inflammation have been hypothesized to provide insight into the shared biology. This study explored and characterized the genetic pleiotropy underpinning adiposity and inflammation using genetic and phenotypic observations from the Cameron County Hispanic Cohort (CCHC). A total of 3,313 samples and >9 million single nucleotide polymorphisms (SNPs) were examined in this study. Mixed model genome-wide association studies (GWAS) were …
Exploring A Novel Nf-ĸb- Inhibiting Nanoparticle For Periodontitis Therapy., Kameswara Satya Srikanth Upadhyayula
Exploring A Novel Nf-ĸb- Inhibiting Nanoparticle For Periodontitis Therapy., Kameswara Satya Srikanth Upadhyayula
Electronic Theses and Dissertations
Periodontitis is an infection-driven inflammatory disease characterized by gingival inflammation and bone loss. The NF-ĸB signaling pathway is pivotal in osteoclastogenesis and infection-induced pro-inflammatory responses. The use of nanoparticles as a vehicle to deliver drug increases stability, loading capacity, and facilitates transmembrane transportation. The hypothesis was that a novel nanoparticle carrying therapeutic NBD inhibitory peptides (NBD-nanoparticles) will inhibit measures of periodontal disease. In this project, we tested the nanoparticles for their ability to directly inhibit osteoclastogenesis and inflammation as an original strategy for periodontitis therapy. We also tested the capability of the nanoparticles to inhibit gingival inflammation and alveolar bone …
Cardiovascular And Hematopoietic Responses To Volatile Benzene Exposure., Wesley Tyler Abplanalp
Cardiovascular And Hematopoietic Responses To Volatile Benzene Exposure., Wesley Tyler Abplanalp
Electronic Theses and Dissertations
The rapid and recent increase in the global epidemic of diabetes and cardiovascular disease suggests a strong component of the environment is contributing. Benzene is a ubiquitous volatile pollutant generated by cigarette smoke, automobile exhaust, wildfires and industrial activities. Consequently, it is found in almost all urban and rural air samples. Benzene is known to cause hematotoxicity and its metabolism generates oxidative stress. Although, benzene has been studied for many years, few investigations have probed what influence benzene exposure may have on other physiological processes. Here we hypothesize that benzene metabolism by hepatic-CYP450 2E1 generates oxidative stress and inflammation, which …
Role Of Microrna-21 In Atherogenesis., Rihab Hamed-Berair
Role Of Microrna-21 In Atherogenesis., Rihab Hamed-Berair
Electronic Theses and Dissertations
MicroRNA-21 (miR-21) is an evolutionarily conserved microRNA, abundant in most cardiovascular tissues. It has been implicated in the pathogenesis of several cardiovascular diseases including restenosis, myocardial infarction, and heart failure. However, little is known about the contribution of miR-21 in atherosclerosis. My data show that expression of miR-21 is increased by >1.5-fold in murine atherosclerotic lesions and by 1.5-2.0-fold in the macrophages of Western diet (WD)-fed LDLR-KO mice (for 12-20 weeks). In vitro, LDL, oxidized LDL, acetylated LDL and LPS induced miR-21 by 2-4-fold and down-regulated its target protein, PDCD4, in bone marrow-derived macrophages. Basally, macrophages isolated from miR-21-KO …
A Plant-Made Cholera Toxin B Subunit Enhances Mucosal Wound Healing And Protects Against Ulcerative Colitis And Colon Cancer., Keegan J Baldauf
A Plant-Made Cholera Toxin B Subunit Enhances Mucosal Wound Healing And Protects Against Ulcerative Colitis And Colon Cancer., Keegan J Baldauf
Electronic Theses and Dissertations
This dissertation describes the previously unidentified effects of a plant-produced recombinant cholera toxin B subunit (CTBp) on the gastrointestinal (GI) tract and its ability to protect against inflammation in a mouse model of colonic injury and ulcerative colitis (UC). To comprehensively analyze CTBp’s impacts on the GI tract, we employed global analysis methodologies based on multi-color flow cytometry to analyze immune cell populations in GI and systemic lymphatic compartments, gene expression microarray to decipher transcript-level changes in the colon and small intestine, and 16S rRNA sequencing to characterize fecal microbiota. Based on a drastic shift observed in the immune cell …
Regulation Of Macrophage Inflammatory Signaling Pathways By Amp-Activated Protein Kinase., Yanfang Zhu
Regulation Of Macrophage Inflammatory Signaling Pathways By Amp-Activated Protein Kinase., Yanfang Zhu
Electronic Theses and Dissertations
AMP-activated protein kinase, AMPK, is a conserved serine/threonine kinase with a critical function in the regulation of metabolic pathways in eukaryotic cells. Recently, AMPK has been shown to play an additional role as a regulator of inflammatory activity in leukocytes. Treatment of macrophages with chemical AMPK activators, or forced expression of a constitutively active form of AMPK, results in polarization to an antiinflammatory phenotype. Additionally, we reported previously that stimulation of macrophages with antiinflammatory cytokines such as IL-10, IL-4 and TGF-ß results in rapid activation of AMPK, suggesting that AMPK contributes to the suppressive function of these cytokines. In the …
