The Staphylococcus Pseudintermedius Adhesin Spsd Contains A Central Fibronectin-Binding Domain, Andrea S. Bordt
The Staphylococcus Pseudintermedius Adhesin Spsd Contains A Central Fibronectin-Binding Domain, Andrea S. Bordt
Dissertations & Theses (Open Access)
Staphylococcus pseudintermedius is a Gram-positive bacterium significant because of its ability to cause costly and difficult to treat veterinary infections worldwide. It exhibits several similarities to Staphylococcus aureus, however, very little is known about its surface adhesins. Surface adhesins in S. aureus are significant contributors to pathogenesis. S. pseudintermedius encodes the surface protein SpsD, which contains characteristics of the microbial surface components recognizing adhesive matrix molecules family and confers attachment of the heterologous host Lactococcus lactis to fibronectin. This work has identified a centrally-located fibronectin binding domain in SpsD which binds the 30 kDa N-terminal domain of fibronectin with …
Prkca: Identification Of A Novel Downstream Target Of Wt1, Devin Jones
Prkca: Identification Of A Novel Downstream Target Of Wt1, Devin Jones
Dissertations & Theses (Open Access)
Wilms tumor is a childhood tumor of the kidney arising from the undifferentiated metanephric mesenchyme. Tumorigenesis is attributed to a number of genetic and epigenetic alterations. In 20% of Wilms tumors, Wilms tumor gene 1 (WT1) undergoes inactivating homozygous mutations causing loss of function of the zinc finger transcription factor it encodes. It is hypothesized that mutations in WT1 result in dysregulation of downstream target genes, leading to aberrant kidney development and/or Wilms tumor. These downstream target genes are largely unknown, and identification is important for further understanding Wilms tumor development. Heatmap data of human Wilms tumor protein …
Characterization Of Jak, Stat, And Src Interactions In Head And Neck Squamous Cell Carcinoma, Reshma Jaseja, Reshma Jaseja
Characterization Of Jak, Stat, And Src Interactions In Head And Neck Squamous Cell Carcinoma, Reshma Jaseja, Reshma Jaseja
Dissertations & Theses (Open Access)
Recurrence of Head and Neck Squamous Cell Carcinoma (HNSCC) is common; thus, it is essential to improve the effectiveness and reduce toxicity of current treatments. Proteins in the Src/Jak/STAT pathway represent potential therapeutic targets, as this pathway is hyperactive in HNSCC and it has roles in cell migration, metastasis, proliferation, survival, and angiogenesis. During short-term Src inhibition, Janus kinase (Jak) 2, and signal transducer and activator of transcription (STAT) 3 and STAT5 are dephosphorylated and inactivated. Following sustained Src inhibition, STAT5 remains inactive, but Jak2 and STAT3 are reactivated following their early inhibition. To further characterize the mechanism of this …
Investigating The Roles Of The P63 Isoforms In The Microrna Biogenesis Pathway, Deepavali Chakravarti
Investigating The Roles Of The P63 Isoforms In The Microrna Biogenesis Pathway, Deepavali Chakravarti
Dissertations & Theses (Open Access)
MicroRNAs play roles in various biological processes like development, tumorigenesis, metastasis and pluripotency. My thesis work has demonstrated roles for p63, a p53 family member, in the upstream regulation of microRNA biogenesis. The p63 gene has a complex gene structure and has multiple isoforms. The TAp63 isoforms contain an acidic transcription activation domain. The ΔNp63 isoforms, lack the TA domain, but have a proline rich region critical for gene transactivation. To understand the functions of these isoforms, the Flores lab generated TAp63 and ΔNp63 conditional knock out mice. Using these mice and tissues and cells from these mice we have …
Acceleration Of The Panin Development In Mice Expressing Oncogenic K-Ras Due To A High Fat Diet, Bincy Philip
Acceleration Of The Panin Development In Mice Expressing Oncogenic K-Ras Due To A High Fat Diet, Bincy Philip
Dissertations & Theses (Open Access)
Obesity is postulated to be one of the major risk factors for pancreatic cancer, and recently it was indicated that an elevated body mass index (BMI correlates strongly with a decrease in patient survival. Despite the evident relationship, the molecular mechanisms involved are unclear. Oncogenic mutation of K-Ras is found early and is universal in pancreatic cancer. Extensive evidence indicates oncogenic K-Ras is not entirely active and it requires a triggering event to surpass the activity of Ras beyond the threshold necessary for a Ras-inflammation feed-forward loop. We hypothesize that high fat intake induces a persistent low level inflammatory response …
