The Pathogenesis Of Natural Killer/T Cell Lymphoma, Bei Jiang
The Pathogenesis Of Natural Killer/T Cell Lymphoma, Bei Jiang
Theses & Dissertations
Extranodal natural killer/T-cell lymphomas (NKTCL) are uncommon lymphomas with poor prognosis. In order to gain a better understanding of the molecular pathogenesis of NKTCL, we obtained and compared the global gene expression profile, global somatic mutation profile, and global methylation profile of normal NK cells, malignant NK cell lines, and NKTCL patient samples. We showed that the JAK-STAT pathway was constitutively activated in NKTCL through the cooperation between activation of signal transducer and activator of transcription proteins (STATs) via activating mutations and inactivation of STAT suppressor protein suppressor of cytokine signaling 6 (SOCS6) through promoter hypermethylation. Activating STAT3 and STAT5B …
Intimin Likely Used To Cause Disease During Competition With Commensal Escherichia Coli, Dominique J. Richburg
Intimin Likely Used To Cause Disease During Competition With Commensal Escherichia Coli, Dominique J. Richburg
Senior Honors Theses
The intimin gene in the Locus of Enterocyte Effacement (LEE) island of pathogenicity is the primary attachment mechanism in Citrobacter rodentium. Intimin is a bacterial adhesin (protein) that attaches to obtain a niche/nutrient and thrive within the intestine. Intimin was deleted within C. rodentium to study colonization and pathogenesis in the murine intestine. Additionally, C. rodentium is an attaching/effacing pathogen, and a useful murine model in understanding Enterohemorrhagic Escherichia coli (EHEC) infection in humans. E. coli and C. rodentium cause gastroenteritis in humans and mice, respectively. C. rodentium is a murine pathogen commonly used to model gastrointestinal disease because …
