Abstract

The activity of the protein tyrosine kinase pp60c-src was determined for each of the 60 human cell lines in the panel used by the National Cancer Institute for the random screening of potential anticancer drugs. The leukemia, lymphoma, melanoma, and small-cell lung cancer derived cell lines had low pp60c-src activity. Surprisingly, non-small-cell lung and ovarian cell lines had a median pp60c-src activity which was greater than that of the panel of cells representing colon cancer, which is most often associated with elevated pp60c-src activity. This data defines homologous cell lines which contain low and high pp60c-src activity which will aid attempts to understand the role of this enzyme in human cancer.

pp60c-src在60种不同人类肿瘤细胞系中的活性。
蛋白酪氨酸激酶pp60c-src的活性是在美国国家癌症研究所用于随机筛选潜在抗癌药物的60种人类细胞系中测定的。白血病、淋巴瘤、黑色素瘤和小细胞肺癌衍生细胞系的pp60c-src活性较低。令人惊讶的是,非小细胞肺和卵巢细胞系的中位pp60c-src活性高于代表结肠癌的细胞组,结肠癌通常与pp60c-src活性升高有关。这些数据定义了含有低和高pp60c-src活性的同源细胞系,这将有助于理解这种酶在人类癌症中的作用。
