Pharmacologic inactivation of kinase suppressor of ras-1 abrogates Ras-mediated pancreatic cancer.

Overview
abstract
Inhibition of the kinase suppressor of ras-1 (KSR1) gene by continuous infusion of phosphorothioate antisense oligonucleotides (ODNs) prevented growth of K-Ras-dependent human PANC-1 pancreatic and A549 non-small-cell lung carcinoma xenografts in nude mice, effected regression of established PANC-1 tumors and inhibited A549 lung metastases, all without apparent toxicity. These studies suggest KSR1 antisense ODNs as a treatment for Ras-dependent human malignancies, in particular pancreatic cancer, which lacks effective curative therapy.
