Identification and characterization of pathways specific to tumor cell survival, but absent in normal tissues, provide opportunities to develop effective cancer therapies with reduced toxicity to the patient. Kinase suppressor of Ras 1 (KSR1) is required for the survival of colorectal cancer (CRC) cells, but dispensable in normal cells. Using KSR1 as a reference standard, we identified EPH (erythropoietin-producing hepatocellular carcinoma) receptor (EPHB4) as a KSR1 functional analog.

We show here that, like KSR1, EPHB4 is aberrantly overexpressed in human CRC cells and selectively required for their survival. Both KSR1 and EPHB4 support tumor cell survival by promoting the expression ...
