Long-term spaceflight causes more changes to gene expression than shorter trips, especially to the immune system and DNA repair systems, according to research by Weill Cornell Medicine and NASA investigators as part of NASA’s Twins Study, which followed the only set of identical twin astronauts for more than two years.  

New studies from Weill Cornell Medicine researchers have revealed the importance of two gene-regulation proteins in the development of common immune cell cancers called lymphomas.

Weill Cornell Medicine investigators Dr. David Lyden and Dr. Ari Melnick have been awarded Outstanding Investigator Awards from the National Cancer Institute.

Errors in the regulation of gene expression may contribute to the development of a common form of blood cancer and point to potential treatment strategies, according to a new study by scientists from Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center.

For decades, Weill Cornell has been a leader in the research revolution that's making lymphoma a survivable disease.
