The study was conducted in the laboratory of Prof. Aaron Ciechanover, an Israeli Nobel-prize winner in chemistry, and led by Dr. Yelena Kravtsova-Ivantsiv. The team included research students and physicians from the Rambam, Carmel and Hadassah Medical Centers.
In a paper published in the journal Cell last week, the researchers showed how the proteins could repress cancerous tissues and detailed how a high concentration of a protein called KPC1 and another called p50 in the tissue can protect it from cancerous tumors.
The research also detailed how the ubiquitin process — a cell system responsible for breaking down damaged proteins that can harm cells and tissues and co-discovered by Ciechanover, for which he won the Nobel — has a role in the mechanism.
The study was done on human tumors grown in mice, and samples of human tumors.
