Scientists discover that thyroid cancer cells become less aggressive in outer space

profiles, employing modern molecular biological techniques, such as whole genome microarrays and multi-analyte profiling. Results suggested that the expression of genes indicating a high malignancy in cancer cells may be down-regulated under altered gravitational stimulation.

"We are just at the beginning of a new field of medicine that studies the effects of microgravity on cell and molecular pathology. Space flight affects our bodies, both for good and bad," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "We've known that microgravity can cause some microorganisms to become more virulent and that prolonged microgravity has negative effects on the human body. Now, we learn that it's not all bad news: what we learn from cells in space should help us understand and treat malignant tumors on the ground."
