Regulation Of The Wnt/Β-Catenin Pathway By Steroid Hormones In Danio Rerio Ovarian Tissue, Macaulie Casey Jan 2015

Regulation Of The Wnt/Β-Catenin Pathway By Steroid Hormones In Danio Rerio Ovarian Tissue, Macaulie Casey

Summer Research

The Wnt/β-catenin signaling pathway regulates genes involved in proliferation (cell growth) and apoptosis (cell death). It has been implicated in ovarian cancer, where higher levels of β-catenin may be involved in the development of tumors. Steroid hormones play a significant role in female reproductive tissue, and studies have shown that estrogens and progestins may regulate the Wnt/β-catenin pathway. My past research suggested testosterone may also affect the pathway. Few studies have investigated how steroid hormone mimics, such as Bisphenol A (BPA), affect these regulatory patterns. This study investigated the affect of estrogen and BPA on the Wnt/β-catenin pathway in Danio …


Oncogene Characterization And Mapping, John Evans Jan 2015

Oncogene Characterization And Mapping, John Evans

Summer Research

New oncogenes can be uncovered using the UAS/GAL4 system in the model organism Drosophila Melanogaster. P-elements allow both UAS and GAL4 to insert into the genome of parental flies. When crossed, both UAS/GAL4 are transferred to the progeny and express both sequence and protein that result in cancerous phenotypes that are easily identifiable using light microscopy. Inverse PCR, sequence analysis and comparison to online databases, e.g. flybase.org, provides simple identification of the culprit gene.


Effect Of Altered Cellular Redox Environment On Oncogenic Activity Of The Drosophila Prl Protein, Frances Welsh Jan 2015

Effect Of Altered Cellular Redox Environment On Oncogenic Activity Of The Drosophila Prl Protein, Frances Welsh

Summer Research

Aberrant expression of members of the phosphatase of regenerating liver (PRL) family has been implicated as a key factor in the progression of several forms of human cancers. However, despite a wide range of studies supporting the role of the enzyme PRL as an oncogene, it has also been identified as a growth suppressor when tested under different conditions. One proposed explanation for this change in function is that redox regulation controls the accessibility of the active site of PRLs, which is necessary for oncogenic output. In this study, cellular redox environment was altered in vivo using Drosophila melanogaster, …
