KRAS and cancer: A functional link between NOP56 and mutant KRAS is supported by a multitude of lines of evidence, i.e., the elevated expression of NOP56 in KRAS-mutant tumors, the prognostic significance of NOP56 expression in patients with KRAS-mutant but not wild-type cancers, and selective damage on KRAS-mutant cancer cells incurred by NOP56 downregulation.
