Abstract

Spontaneous tumor regression has been documented in a small proportion of human cancer patients, but the specificmechanisms underlying tumor regression without treatment are not well understood. Tasmanian devils are threatened with extinctionfrom a transmissible cancer due to universal susceptibility and a near 100% case fatality rate. In over 10,000 cases, RASL11Asignificantly contributes to tumor regression. RASL11A was expressed in regressed tumors but silenced in wild-type, nonregressedtumors, consistent with RASL11A downregulation in human cancers. Induced RASL11A expression significantly reduced tumor cellproliferation in vitro. The RAS pathway is frequently altered in human cancers, and RASL11A activation may provide a therapeutictreatment option for Tasmanian devils as well as a general mechanism for tumor inhibition.
