Squamous Cell carcinoma cell line 에서 cellular proto - oncogene 들의 증폭 및 발현
김경순,박노희 ( Kyung Soon Kim,No Hee Park ) 생화학분자생물학회 1990 BMB Reports Vol.23 No.2
The restriction profiles and expression of various cellular proto-oncogenes in normal human epidermal keratinocytes and human syuamous cell carcinoma cell lines were studied. Both normal human epidermal keratinocytes and cancer cell lines contained and expressed various proto-oncogenes such as erb-B-I, abl, fos, raf, H-ras, and myc. Although the Eco RI restriction profiles of the oncogenes from the normal cells and cancer cells were similar, the amount of the oncogene in the cancer cell lines was generally higher than that in the NHEK. Furthermore, the amount of expression of these proto-oncogenes was significantly higher in the cancer cell lines than in the normal keratinocytes. These data indicate that the overexpression of several cellular proto-oncogenes might be necessary for the malignant transformation and maintenance of the malignancies of syuamous cell carcinoma.

사람의 정상적 epidermal keratinocyte(NHEK)와 사람의 squamous cell carcinoma cell line에서 여러 가지 cellular proto-oncogene의 존재, restriction profile, 그리고 expession을 조사하였다. NHEK와 cell line들로부터 얻은 발암유전자의 Eco RI restriction profile은 유사하였고 정상세포와 암세포들은 모두 몇 가지 proto-oncogene들을 발현하였으나 NHEK에 비해 암세포에서 이들 proto-oncogene의 발현되는 양이 많았다. 이 결과로부터 squamous cell carcinoma의 malignant transformation과 그 유지에 있어서 몇 가지 cellular proto-oncogene들의 과발현이 필요하다는 것을 알 수 있다.
