The Boudreaux laboratory is interested in cellular host factors that play a role in rotavirus replication. Rotaviruses remain a leading cause of childhood diarrheal death worldwide. In the state of West Virginia, enteric illnesses are the second most common type of disease outbreak. Recent surveillance showed half the Southern Regional average of rotavirus infections were recorded in West Virginia. Various attributions because of rural populated areas in the state may lead to increased outbreaks.
Viruses subvert cellular factors and signaling pathways to take command of the cellular environment for effective replication. All viruses do not have the same approach to subvert cellular factors, however, most viruses encode proteins that redirect cellular protein recruitment. Rotaviruses are triple layered, non-enveloped, segmented, double-stranded RNA viruses with a life cycle that occurs entirely in the cytoplasm of infected cells. Towards identifying cellular candidate proteins that may be involved in rotavirus replication, an RNA interference (RNAi) screen was performed using a library of lentiviral-encoded short hairpin RNAs (shRNAs) focusing solely on cellular kinases. Our focus is to elucidate mechanisms by which these cellular kinases function to promote rotavirus infection. This work is important for developing new antiviral treatments.
