Tool Details

  • Tool name: DOK Cell Line
  • Tool type: Cell Lines
  • Parental cell line:
  • Organism: Human
  • Tissue: Tongue
  • Cancer type: Human Caucasian dysplastic oral keratinocyte
  • Disease: Cancer
  • Conditional: Yes
  • Description: The degree of dysplasia in the patient was described as mild to moderate. The cells show some stratification in confluent cultures and contain a keratin profile similar to the original dysplasia. Growth is stimulated by hydrocortisone and inhibited by cholera toxin. Expression of p53 is increased and a 12 bp in-frame deletion of the p53 gene (codon 188-191) could be identified. DOK cells are non-tumourigenic in athymic nude mice.
  • Research area: Cancer ; Drug Discovery & Development
