Daniel Sotelo: Alterations in Gene Expression Profiles

Daniel Soto is a junior majoring in Nutrition Sciences. He conducted his research with a graduate student in pharmacology and toxicology and under the direction of Dr. Walt Klimecklin of The University of Arizona College of Pharmacy and BIO5 Institute. Daniel explains that the project's was to use quantitative RTPCR to look at gene expression to see how the genes were reacting at various time points to arsenic exposure, non-arsenic exposure and the recovery. What he found was that arsenic does have the ability to permanently alter gene expression.

One of the unique experiences available to undergraduate students at The University of Arizona is the opportunity to engage in original research. UA undergrads work alongside research professors, graduate students and post-doctoral fellows, often in paid positions, and often are included as authors on papers published in academic journals. Nearly 30 students presented their work at the 22nd annual Undergraduate Research Forum, held on February 25, 2009.
