Resolving The Repression Pathway Of Virulence Gene Hila In Salmonella, Alexandra King, Lon Chubiz Phd, Brenda Pratte, Lauren Daugherty
Undergraduate Research Symposium
Salmonella is a relatively abundant, virulent species of bacteria that is most known for spreading gastrointestinal diseases through food. These illnesses result in approximately 1.35 million infections, including over 25,000 hospitalizations each year, in the U.S. alone (CDC.gov). As antibiotic resistance becomes an increasingly urgent public health problem, the importance of developing alternative treatment methods is only becoming more crucial. One of the genes responsible for this virulence is known as hilA. HilA is the main transcriptional regulator of Salmonella Pathogenicity Island-1 gene (UniProt). SPI-1 plays an important role in the invasion of Salmonella into epithelial cells. The proteins encoded …
Examination Of Human Embryonic Kidney Cells And Cardiomyocytes Using Glass Microcarrier Beads And Scanning Electron Microscopy, Jaekook Sim
Undergraduate Research Symposium
Alterations of sarcomeric proteins lead to disruption of myofilaments and are associated with hypertrophic cardiomyopathy. We have identified a genetically altered mouse strain with an elevated level of actin associated protein and are characterizing the nature of the hypertrophy by examining the cultured cells on glass microcarrier beads using Scanning Electron Microscopy (SEM). Beads provide a surface for cell growth and division and subsequent analysis of myocyte morphology. This study requires the establishment of primary embryonic cardiomyocyte culture which is difficult to establish. Therefore in initial studies to acquire the necessary tissue culture skill, we cultured Human Embryonic Kidney (HEK) …
