Potential new eye tumor treatment discovered

New research from a team including several Carnegie scientists demonstrates that a specific small segment of RNA could play a key role in the growth of a type of malignant childhood eye tumor called retinoblastoma. The tumor is associated with mutations of a protein called Rb, or retinoblastoma protein. Dysfunctional Rb is also involved with other types of cancers, including lung, brain, breast and bone. Their work, which will be the cover story of the August 15th issue of Genes & Development, could result in a new therapeutic target for treating this rare form of cancer and potentially other cancers as well.
