100353August 12, 2011, Greencastle, Ind. — Samuel S.C. Rund, a 2008 graduate of DePauw University, is lead author of research published in the latest edition (August 9, 2011; vol. 108, no. 32) of Proceedings of the National Academy of Sciences. Rund and four others contribute "Genome-wide profiling of diel and circadian gene expression in the malaria vector Anopheles gambiae."

An abstract of the article notes, "Anopheles gambiae, the primary African vector of malaria parasites, exhibits numerous rhythmic behaviors including flight activity, swarming, mating, host seeking, egg laying, and sugar feeding. However, little work has been performed to elucidate the molecular basis for these daily rhythms. To study how gene expression 100354is regulated globally by diel and circadian mechanisms, we have undertaken a DNA microarray analysis of An. gambiae under light/dark cycle (LD) and constant dark (DD) conditions ... This study highlights the fundamental roles that both the circadian clock and light play in the physiology of this important insect vector and suggests targets for intervention."
