Characterizing The Role Of Pa5189 Of Pseudomonas Aeruginosa In Deletion And Overexpression Mutants, Seh Na Mellick
Characterizing The Role Of Pa5189 Of Pseudomonas Aeruginosa In Deletion And Overexpression Mutants, Seh Na Mellick
Theses/Capstones/Creative Projects
In the context of rising multidrug resistance in biofilm-forming pathogens like Pseudomonas aeruginosa, this study investigates the role of the understudied transcription factor PA5189 in antibiotic resistance and biofilm formation. PA5189 deletion and overexpression mutants were created in a parent P. aeruginosa strain using pEX18Tc-based recombinant suicide vectors, with genotypic verification of putative triparental conjugants achieved through restriction digestion and PCR. The study revealed that PA5189 overexpression significantly increases resistance to commonly used broad spectrum antibiotics such as ciprofloxacin and imipenem. Additionally, differential expression of PA5189 was found to notably affect biofilm formation, with variations contingent on the nutrient …
Predicting The Identities Of Su(Met-2) And Met-3 In Neurospora Crassa By Genome Resequencing, Kevin Mccluskey, Daren Brown, Erin Bredeweg, Scott E. Baker
Predicting The Identities Of Su(Met-2) And Met-3 In Neurospora Crassa By Genome Resequencing, Kevin Mccluskey, Daren Brown, Erin Bredeweg, Scott E. Baker
Fungal Genetics Reports
A significant number of classical genetic Neurospora crassa biochemical mutants remain anonymous, unassociated with a physical genome locus. By utilizing short read next-generation sequencing methods, it is possible to sequence the genomes of mutant strains rapidly and economically for the purpose of identifying genes associated with mutant phenotypes. We have taken this approach to connect genes and mutations to “methionineless” phenotypes in N. crassa.
Chemical Synthesis Of Sensitive Dna, Komal Chillar
Chemical Synthesis Of Sensitive Dna, Komal Chillar
Dissertations, Master's Theses and Master's Reports
Over the past decades, researchers have tried various chemical methods to synthesize modified oligodeoxynucleotides (ODNs, i.e. short segments of DNAs). Traditional ODN synthesis methods require strong basic, and nucleophilic conditions for the deprotection and cleavage of the ODN from the solid support. However, the sensitive ODNs containing labile functionalities are vulnerable to such harsh conditions. Sensitive ODNs have a wide range of applications in research and pharmaceuticals. To synthesize sensitive ODNs, researchers devised different strategies but no practical methods have been developed. To overcome these challenges, we developed alkyl Dim alkyl Dmoc technology. This innovative technology uses weakly basic and …
Structural And Functional Consequences Of Pde6 Prenylation In Rod And Cone Photoreceptors, Faezeh Moakedi
Structural And Functional Consequences Of Pde6 Prenylation In Rod And Cone Photoreceptors, Faezeh Moakedi
Graduate Theses, Dissertations, and Problem Reports
Phosphodiesterase-6 (PDE6) serves as a pivotal component in the phototransduction pathways of both cone and rod photoreceptors. In cones, PDE6 consists of tetrameric subunits: inhibitory (γ') and catalytic (α'). The catalytic subunit, PDE6α', contains a C-terminal prenylation motif. Deletion of this motif is associated with achromatopsia (ACHM), a form of color blindness. The mechanisms underlying the disease and the roles of PDE6 lipidation in vision remain elusive. Meanwhile, rod PDE6 is composed of α and β catalytic subunits and γ inhibitory subunits, with alterations in the C-terminal "prenylation motif" of PDE6β linked to retinitis pigmentosa (RP) pathology. In this comprehensive …

Azathioprine is a pro-drug and is metabolized by the TPMT enzyme in the body. In South Asians, Azathioprine is known to cause alopecia and bone marrow suppression in patients with TPMT enzyme deficiency. In India, the prevalence of TPMT mutation varies from 1.2- 10%. A new mutation was detected in 2014, NUDT15 whose incidence varies from 8.5-16%. Patients with mutation in both TPMT and NUDT15 develop myelosuppression faster. In our case, alopecia manifested as the first clinical feature of Azathioprine myelosuppression. Physicians need to recognize early clinical clues (alopecia) to avoid the impending development of myelosuppression and to look for …
