Genomic Epidemiology Of Clinical Salmonella Enterica In New Hampshire, 2017-2020, Madison R. Turcotte
Genomic Epidemiology Of Clinical Salmonella Enterica In New Hampshire, 2017-2020, Madison R. Turcotte
Legacy Theses & Dissertations (2009 - 2024)
Antimicrobial resistance in Salmonella enterica remains a challenging public health threat. We aim to characterize the population structure and evolutionary history of 394 genomes of S. enterica isolates recovered from human clinical cases in New Hampshire, USA from 2017 to 2020. The population is phylogenetically diverse, consisting of 78 STs and 67 serotypes. We detected 61 genes associated with resistance to14 different antimicrobial classes. Rather than a single multidrug resistant clone expanding in the state, we found multiple lineages carrying different combinations of independently acquired resistance determinants. New or emerging lineages can therefore rapidly spread over relatively short timeframes. In …

Long Noncoding Rna Ak001796 As A Mediator Of Epithelial-To-Mesenchymal Transition In Metastatic Breast Cancer, Sumayya Adib Alchalabi

Long noncoding RNAs (lncRNAs) are emerging as key molecules regulating several cellular pathways and contributing to the development and progression of different diseases including cancer. The epithelial-to- mesenchymal transition (EMT), a molecular reprogramming process that plays a critical role in cancer metastasis, involves a complex interaction between protein coding and non-coding transcripts including lncRNAs. Understanding the biological significance of those lncRNAs of relatively unknown function, may help to uncover potential therapeutic targets for the aggressive subtypes of breast and other cancers. In this study, we examined the expression profiles of more than 17,000 lncRNAs in a large set of patients’ …

Malaria is the most deadly vector borne disease, causing substantial morbidity and hundreds of thousands of deaths worldwide each year. In the Americas, the incidence of malaria has increased steadily since 2014. The factors driving continued malaria transmission are complex and highly variable across endemic areas. These factors include inadequate access and financial commitment to prevention, diagnosis, and treatment, and a failure to target interventions to heterogeneous malaria transmission patterns and vector populations. Nyssorhynchus darlingi (formerly Anopheles darlingi), the predominant malaria vector in Latin America, is known for behavioral, phenotypic, and genetic variability across its range, which allow it to …

Rna Aptamers For Molecular Chaperones Hsp27 And Hsp90, Sathishkumar Kumar Munusamy
Legacy Theses & Dissertations (2009 - 2024)
Hsp90 and Hsp27 are members of the heat shock protein family of chaperones that perform multiple roles in cellular maintenance through protein folding and inhibition of apoptosis. They are abundantly expressed in cells and are over-expressed during conditions of stress. Hsp90 requires ATP for its chaperone function while Hsp27 self-associates into higher order oligomers enclosing its substrate. Their ability to interact with other proteins or with themselves lies at the heart of their mechanisms. The specific consequences of each of their interactions on global cellular health have not yet been fully discovered. The sheer diversity of proteins that interact with …

Inflammatory breast cancer (IBC) is a rare and particularly lethal form of breast cancer. Despite aggressive therapeutic approaches, the 5-year survival rate is only 34%. As this disease is severely understudied, we have investigated the therapeutic potential of the novel hydroxamic acid-derived histone deacetylase inhibitor (HDACi), CG-1521 in comparison to a structurally similar compound, Trichostatin A (TSA) in two IBC cell lines: SUM149PT and SUM190PT. In these cells, CG-1521 and TSA induce dose- and time-dependent induction of cell cycle arrest and apoptosis regardless of the presence of 17β-estradiol (E2). Interestingly, the cell lines have considerably different sensitivities to these treatments …
Detection And Epidemiological Patterns Of Drug Resistance Mutations In Nys Plasmodium Falciparum Clinical Malaria Specimens, Jennifer L. Conaway
Detection And Epidemiological Patterns Of Drug Resistance Mutations In Nys Plasmodium Falciparum Clinical Malaria Specimens, Jennifer L. Conaway
Legacy Theses & Dissertations (2009 - 2024)
Plasmodium falciparum is a human-infective parasite that causes the most severe form of malaria. Resistance to a wide spectrum of antimalarials has been documented in this species, and single strains may be resistant to several drugs. A new technology, pyrosequencing, has been shown to be useful for the rapid detection of SNPs involved in drug resistance. It can be used in a clinical setting and readily detects new mutants, which frequently appear in this species due to strong selection for antimalarial resistance. In this study, a pyrosequencing protocol was developed to identify mutations in the Plasmodium falciparum genes Pfcrt, Pfdhps, …
