Transactivation And Mitochondrial Activity Are Affected By High Temperature In C. Elegans Sperm, Jacqueline Mcvay
Transactivation And Mitochondrial Activity Are Affected By High Temperature In C. Elegans Sperm, Jacqueline Mcvay
Scripps Senior Theses
Sexual reproduction has a conserved flaw in that it is temperature sensitive. Exposure to high temperature leads to male infertility, but little is known about the underlying mechanism. Understanding these mechanisms is important for agriculture and reproductive medicine. Using C. elegans, we investigated two potential aspects of male fertility that may be affected by high temperature conditions: activation of sperm by seminal fluid and sperm mitochondrial activity. There are two pathways for sperm activation in C. elegans: the SPE-8 pathway in hermaphrodites and the TRY-5 pathway in male seminal fluid. Hermaphrodite sperm with a mutation in spe-8 can …
Changes In Cell Morphology And The Cellular Localization Of Protein Kinase Dsk1 In Schizosaccharomyces Pombe In Response To Butylated Hydroxyanisole, Jacqueline T. Humphries
Changes In Cell Morphology And The Cellular Localization Of Protein Kinase Dsk1 In Schizosaccharomyces Pombe In Response To Butylated Hydroxyanisole, Jacqueline T. Humphries
Scripps Senior Theses
Dsk1 is the Schizosaccharomyces pombe functional homolog of human SRPK1, an SR protein kinase that regulates localization and function of SR protein splicing factors involved in transcription, alternative splicing, and mRNA export. It has been shown that a Dsk1 deletion strain of S. pombe is sensitive to exposure to butylated hydroxyanisole (BHA), a phenol derivative commonly used as a food preservative. Little is known about how BHA interacts with cells on a functional level, although it has been shown to be cytotoxic and tumorigenic. The aims of this thesis are to study the effect of BHA on eukaryotic cells and …
