A Florida State University researcher is on a mission to explore the gene-controlling effects of addictive drugs in pursuit of new HIV treatments.

Working under the support of a $1.8 million grant from the National Institutes of Health (NIH), Florida State biologist Jonathan Dennis is studying a unique ability shared between a promising class of HIV treatments known as histone deacetylase inhibitors (HDIs) and psychostimulant drugs such as cocaine.

"Current HIV treatments do just that -- they treat the disease by preventing the spread of HIV in the body, rather than eliminating the disease entirely," Dennis said. "I want to find out how to root out those dormant HIV cells that are evading the treatment, and I believe the gene-controlling functions shared by HDIs and psychostimulant drugs hold the key to helping us do that."

HDIs and addictive drugs such as cocaine share the ability to control gene expression through changes in the chromatin structure within DNA. In the case of HDI treatment, the chromatin changes are used to wake up dormant HIV virus cells that are hiding in the body.

Dennis believes that addictive drugs do the same thing. Dennis' work will focus on identifying and understanding the overlapping gene changes that occur between these two types of substances, ultimately providing other researchers with the foundational information they need to turn HDI treatments into HIV cures.

Florida State professor Jonathan Dennis is researching the similarities between addictive drugs and HIV treatments in hopes of finding a cure for the disease.

Using the resources available through Florida State University's unique Integrating Genotype and Phenotype research cluster, Dennis was able to lure the attention of the NIH and obtain the grant. Genotype is the genetic constitution of an organism while the phenotype is its appearance and functional properties.

This research cluster combines cross-disciplinary expertise in the areas of evolutionary biology, molecular biology, genomics and epigenetics to solve one of the most important problems facing biology in the 21st century -- the relationship between genotype and phenotype.

"The Integrating Genotype and Phenotype cluster has been critical in my work to unravel the mysteries behind chromatin and gene expression through direct access to other researchers and their areas of expertise," Dennis said. "Without it I would not have been able to obtain this grant and be able to focus my work on helping the scientific community find a cure for HIV."
