Biliverdine 106-116 KRAS proto-oncogene, GTPase Rattus norvegicus 167-175 2647284-0 1989 Over expression of proto-oncogenes: ki-ras, fos and myc in rat liver cells treated in vitro by two liver tumor promoters: phenobarbital and biliverdin. Biliverdine 140-150 KRAS proto-oncogene, GTPase Rattus norvegicus 36-42
