Ras proteins control signaling pathways that are believed to be key regulators of both normal cell growth and malignant transformation.
The grant entitled "Radiosensitization by Anti-Ras scFv-Expressing Adenovirus" will fund studies in the use of AV1Y28, a modified adenoviral vector that carries a gene encoding a single-chain antibody fragment directed against Ras proteins.
ras proteins play a key role in transmitting signals from outside the cell through a number of different pathways into the nucleus of the cell, a process called signal transduction.
These antibodies are useful in detecting mutant ras proteins which have been shown to be early events in the development of 30-50% of colon cancer cases, approximately 90% of pancreatic cancer cases, and 30% of lung cancer cases.
Recently published reports have shown the presence of these ras mutations in plasma samples and therefore the ability to detect the presence of these mutant ras proteins in blood samples may be valuable for the early detection of malignancy.
