EXPERIMENT INFORMATION

Comparison of Ground and On-Orbit DNA Synthesis in Rat Gastric Epithelium During STS-54 (PARE02 BSP6)
Principal Investigator
Research Area:
Gastrointestinal physiology
Species Studied
Scientific Name: Rattus norvegicus Species: Rat Strain: Sprague-Dawley

Description
OBJECTIVES:
Measurement of on-orbit and ground DNA synthesis in rat gastric epithelium is the subject of this study. Is will not be known at the conclusion of the experiment what elements of the space environment might be responsible for any changes in DNA synthesis that are observed. Regardless of the cause, demonstration of such changes would be an important finding. Ultimately, electromagnetic etiologies could rather easily be confirmed or ruled out by subsequent on-orbit experiments in which magnetic shielding materials are employed.
