My skills lie in the areas of gene transcription and general molecular biology. I have investigated the up-regulation of numerous genes in teleosts, induced by estrogenic chemicals and other xenobiotics known to be present in the Nation’s surface waters. These laboratory studies include: (1) vitellogenin gene regulation in male adult fathead minnow exposed to endocrine disrupting chemicals (EDCs) [i.e., nonylphenol (NP), 17α-ethynylestradiol (EE2), 17β-estradiol (E2), and estrone (E1)] and plastisizers, such as 2-diethyl-hexyl phthalate, and (2) metallothionein gene induction in fathead minnow exposed to metals,such as copper, cadmium and zinc. Gene expression data for these studies is generated by employing state-of-the-art techniques, such as reverse transcription polymerase chain reaction (RT-PCR) and real time quantitative PCR. I have developed method for the isolation of RNA from a
single 24 to 48 hour old fathead minnow larvae for use in gene expression studies.
