- Description: DOK (dysplastic oral keratinocyte) cell line was isolated from a piece of dorsal tongue from a 57 year old man (who was a heavy smoker). 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. This cell line can be used to study carcinogens associated with tobacco and their implications in malignant transformation.
- Application: Study of oral keratinocytes, multi-stage oral carcinogenesis
- Production details: The dysplastic oral keratinocyte cell line DOK was isolated from a piece of dorsal tongue from a 57 year old man. After a squamous-cell carcinoma was removed from the patient, who had been a heavy smoker, the remaining dysplasia was removed subsequently and used to initiate primary cultures leading to the establishment of DOK.
