作者采用葡聚糖包被活性碳饱和分析法（DCC法）分别测定了培养的人胃低分化腺癌SGC－7901细胞的胞浆及胞核KCL抽提液中的雌激素受体（ER）、孕激素受体（PR）和雄激素受体（AR）的含量。结果证明胃癌SGC-7901细胞的胞浆及胞核抽提液中ER含量为30．2和35．7fmol/mg蛋白，而PR的含量为20．3和22．7fmol／ng蛋白，但AR均为阴性（＜10fmol／mg蛋白），这说明SGC-7901细胞为ER及PR阳性细胞，其ER和PR在胞浆、胞核中均有分布。提示胃癌可能为性激素依赖性肿瘤，有内分泌治疗的可能。
The authors used dextran-coated activated carbon saturation analysis (DCC) to determine the estrogen receptor (ER) in the cytoplasm and nucleus KCL extracts of human gastric poorly differentiated adenocarcinoma SGC-7901 cells. Progesterone receptor (PR) and androgen receptor (AR) levels. The results showed that the cytoplasm and nucleus extracts of gastric cancer SGC-7901 cells contained 30.2 and 35.7 fmol/mg ER, while the PR content was 20.3 and 22.7 fmol/ng protein, but the AR It is negative (<10 fmol/mg protein), indicating that SGC-7901 cells are ER and PR positive cells, and their ER and PR are distributed in cytoplasm and nucleus. It is suggested that gastric cancer may be a sex hormone-dependent tumor and there is a possibility of endocrine therapy.
