Novel Long Non-Coding Rna Cdlinc Promotes Nsclc Progression, Christina J. Moss
USF Tampa Graduate Theses and Dissertations
Non-small cell lung cancer (NSCLC) is the leading cause of cancer death worldwide with a low 5-year survival rate of only around 21%. This low 5-year survival rate is due to two main reasons. First, NSCLC is often diagnosed at the later stages when it has already metastasized. Second, NSCLC is an incredibly diverse, heterogenous disease making it very hard to target the true molecular oncogenic drivers. New targets for personalized therapeutics are needed based on the expression status of each individual lung cancer tumor.
One way of looking for these new therapeutics is to begin by identifying the oncogenotype …

Myc Distant Enhancers Underlie Ovarian Cancer Susceptibility At The 8q24.21 Locus, Anxhela Gjyshi Gustafson
USF Tampa Graduate Theses and Dissertations
Ovarian cancer is a leading cause of death among women diagnosed with cancer. Mortality rate is high because an overwhelming majority of new cases are diagnosed with late-stage disease when the survival statistics are very poor with an overall 5-year survival rate of less than 40%. Despite the large burden of disease, the etiology of ovarian cancer is not well understood. In addition to linkage studies that have identified highly penetrant cancer susceptibility genes such as BRCA1 and BRCA2, the emergence of Genome Wide Association Studies (GWAS) in the last decade has facilitated the identification of common genetic variants with …
Nonreplicative Dna Helicases Involved In Maintaining Genome Stability, Salahuddin Syed
Nonreplicative Dna Helicases Involved In Maintaining Genome Stability, Salahuddin Syed
USF Tampa Graduate Theses and Dissertations
Double-strand breaks and stalled forks arise when the replication machinery encounters damage from exogenous sources like DNA damaging agents or ionizing radiation, and require specific DNA helicases to resolve these structures. Sgs1 of Saccharomyces cerevisiae is a member of the RecQ family of DNA helicases and has a role in DNA repair and recombination. The RecQ family includes human genes BLM, WRN, RECQL4, RECQL1, and RECQL5. Mutations in BLM, WRN, and RECQL4 result in genetic disorders characterized by developmental abnormalities and a predisposition to cancer. All RecQ helicases have common features including a …
Functional Analysis Of The Ovarian Cancer Susceptibility Locus At 9p22.2 Reveals A Transcription Regulatory Network Mediated By Bnc2 In Ovarian Cells, Melissa Buckley
Functional Analysis Of The Ovarian Cancer Susceptibility Locus At 9p22.2 Reveals A Transcription Regulatory Network Mediated By Bnc2 In Ovarian Cells, Melissa Buckley
USF Tampa Graduate Theses and Dissertations
GWAS have identified several chromosomal loci associated with ovarian cancer risk. However, the mechanism underlying these associations remains elusive. We identify candidate functional Single Nucleotide Polymorphisms (SNPs) at the 9p22.2 ovarian cancer susceptibility locus, several of which map to transcriptional regulatory elements active in ovarian cells identified by FAIRE-seq (Formaldehyde assisted isolation of regulatory elements followed by sequencing) and ChIP-seq (Chromatin Immunoprecipitation followed by sequencing) in relevant cell types. Reporter and electrophoretic mobility shift assays (EMSA) determined the extent to which candidate SNPs had allele specific effects. Chromosome conformation capture (3C) reveals a physical association between Basonuclin 2 (BNC2) and …
Sirt1 Regulation Of The Heat Shock Response In An Hsf1-Dependent Manner And The Impact Of Caloric Restriction, Rachel Rene Raynes
Sirt1 Regulation Of The Heat Shock Response In An Hsf1-Dependent Manner And The Impact Of Caloric Restriction, Rachel Rene Raynes
USF Tampa Graduate Theses and Dissertations
The heat shock response (HSR) is the cell's molecular reaction to protein damaging stress and is critical in the management of denatured proteins. Activation of HSF1, the master transcriptional regulator of the HSR, results in the induction of molecular chaperones called heat shock proteins (HSPs). Transcription of hsp genes is promoted by the hyperphosphorylation of HSF1, while the attenuation of the HSR is regulated by a dual mechanism involving negative feedback inhibition from HSPs and acetylation at a critical lysine residue within the DNA binding domain of HSF1, which results in a loss of affinity for DNA. SIRT1 is a …

From Dna To Protein: A Study Of Genomic Instability Candidate Genes During Zebrafish Development, Kristine Griffett
USF Tampa Graduate Theses and Dissertations
The zebrafish, Danio rerio, is a type of freshwater minnow often used to model human diseases including cancer, anxiety and aging diseases. The overall biology of zebrafish is strikingly similar to that of humans, allowing these fish to be used for drug discovery and toxicology studies for preclinical trials. In this study, zebrafish embryos were used to identify and characterize several candidate genes within two known regions of genomic instability on chromosome 18 and chromosome 4. This fish that were used in this study had been previously classified as genomic instability (gin) mutants due to increased incidence of somatic mutation …
