HEART FLIES experiment to use fruit flies to study effects of space flight on heart
CAPE CANAVERAL, Fla — Another winner of Space Florida’s ISS Research Competition, Project HEART FLIES (Heart Effect Analysis Research Team conducting Fly Investigations and Experiments in Spaceflight), was involved in the CRS-3 trip to the ISS, which launched on Friday, April 18 and berthed on Sunday, April 20.
Drosophila melanogaster —that is, fruit flies — are the payload, and the goal is to observe the effects of spaceflight on the structure, function and gene expression of fruit fly hearts. It is the first study of its kind.
The project, led in part by Dr. Sharmila Bhattacharya, director of the Biomodel Behavior and Performance Lab at the NASA Ames Research Center and a co-principal investigator for the project, should help scientists understand the effects of spaceflight on the human cardiovascular system and to use that information to create appropriate precautions and treatments for future astronauts.

“Many of the genetic and molecular mechanisms involved in heart development and function are remarkably well conserved between flies and mammals, and sophisticated assessments of Drosophila heart function and structure can be performed,” according to the NASA website.
The payload flies will be compared with a control group of ground-based flies. Two normal strains of the fly are included in the study, along with a strain that is genetically predisposed to abnormal heart rhythms. The flies will be in orbit for about thirty days.
Dr. Peter H. Lee is the principal investigator for the study, and Dr. Rolf Bodmer and Dr. Karen Ocorr are co-investigators with Bhattacharya.
Project HEART FLIES and Project MERCCURI both launched with CRS-3. The other five winners of the ISS Research Competition are currently scheduled to launch on SpaceX CRS-4 on July 25, 2014.
