Investigating The Essential Roles Of Dprl-1 In Drosophila Melanogaster, Alex Lee Jan 2017

Investigating The Essential Roles Of Dprl-1 In Drosophila Melanogaster, Alex Lee

Summer Research

Phosphatase of Regenerating Liver (PRL) proteins regulate a number of important cellular processes, including cell growth and division. Humans have three PRL proteins: PRL-1, PRL-2, and PRL-3. An accumulation of evidence has shown that elevated levels of PRLs are strongly correlated with uncontrollable growth and metastasis of tumors. However, contradictory findings have arisen indicating that PRLs instead function to halt cell division thereby preventing uncontrollable tumor growth. In light of these results, the underlying mechanisms regarding how PRLs function within cellular processes remains unclear. To investigate the functions of PRLs, we will create transgenic fruit flies (Drosophila melanogaster) with knockout ...


Epigenetic Regulation Of Gene Expression During Spermatogenesis, Karishma Nayak May 2016

Epigenetic Regulation Of Gene Expression During Spermatogenesis, Karishma Nayak

Senior Honors Projects

In the US livestock production industry, improving reproductive efficiency will improve animal welfare and maintain reasonable costs of meat and milk for consumers. In recent research, abnormalities in epigenetic markers in sperm during spermatogenesis, has been linked to male subfertility in many species. Epigenetics is the study of changes in organisms caused by modifications of gene expression, including DNA methylation, rather than alteration of the genetic code itself. When this process is disturbed, it can negatively impact semen therefore decreasing its fertility. Through further research on how DNA methylation influences gene expression during spermatogenesis and its impact on sperm quality ...
