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

Summer Research
The Phosphatase of Regenerating Liver (PRL) family of proteins control cell growth, motility and proliferation. They have been shown to elevate the levels of these functions, leading to an increase in cancer metastasis (“malignancy”), when they are overexpressed. The goal of this experiment is to knockout PRL gene expression to examine the general function of PRL proteins. Drosophila melanogaster have only one copy of the PRL gene (dPRL-1), as opposed to humans and other mammals, which have 3. Thus, using P-element imprecise excision to create mutant strains either fully lacking or with decreased function of the dPRL-1 protein, …
