Understanding Pseudomonas Aeruginosa Alginate Regulation And Its Link To Chronic Lung Infections In Cystic Fibrosis Patients, Roy Al Ahmar
Understanding Pseudomonas Aeruginosa Alginate Regulation And Its Link To Chronic Lung Infections In Cystic Fibrosis Patients, Roy Al Ahmar
Theses, Dissertations and Capstones
Cystic Fibrosis (CF) is a genetic disorder caused by mutations in the gene encoding Cystic Fibrosis Transmembrane Conductance Regulator (CFTR). This disorder results in thick lung secretions which compromise the patient’s immune system. Chronic lung infections with Pseudomonas aeruginosa biofilms is a major factor that contributes to poor outcome for clinical treatment. The overall hypothesis of this dissertation is that small colony variant and pyrimidine biosynthesis are linked with biofilm formation, alginate production is dependent on MucA proteolysis, rifaximin can be repurposed to treat biofilm infection and multiplex PCR can be used to rapidly measure the bacterial cell density in …

The eukaryotic genome is packaged into chromosomes that are made up of a highly organized and heavily regulated structure called chromatin. The proteins involved in the compaction of DNA into this condensed state are mostly understood at the level of the structure of the nucleosome. The higher order arrangement of chromatin and how it effects gene regulation is only partially understood and characterized. The compaction of nucleosomal arrays into 30-nm and higher structures are partially the responsibility of architectural, or structural, chromatin associated proteins. The following dissertation analyzes the individual chromatin contributions of two well studied architectural proteins, the yeast …

Polymerase stop assays, used to quantify DNA damage, assume single lesions are sufficient to block thermostable DNA polymerase progression. To explore this assumption, 90 base oligonucleotides containing normal or modified DNA bases were amplified using real-time PCR. Data implied that the PCR efficiency was influenced to differing degrees depending on which base lesion was present on the input oligonucleotide; specifically, while reactions with templates containing a single 8-oxo-7,8-dihydro-2í-deoxyguanosine (8-oxodG) were not noticeably altered, the presence of a single 8-oxo-7,8-dihydro-2í-deoxyadenosine, an abasic site, or a cis-syn thymidine dimer (TT dimer) dramatically delayed amplification. In addition, the presence of two tandem 8-oxodGs …
