使用HPTLC(高效薄层色谱法)研究了23例原发性肿瘤和4例5个转移灶中人肾细胞癌糖脂的表达模式。原发性肿瘤中糖脂的表达模式具有组织学细胞类型的特征。在颗粒细胞癌中,乳糖神经酰胺(CDH),GM3和长链神经节苷脂(神经节苷脂迁移比GM3慢)增加,尽管在透明细胞癌中,CDH和其他糖脂倾向于减少。无论细胞类型如何,除1例外,所有病例中的Globoside均降低。在透明细胞型转移性病变中,长链神经节苷脂显著增加是特征性的。此外,在14例原发性透明细胞癌患者中的3例中显示了与转移性病变相同的表达模式,所有患者均在根治性肾切除术后不久发生转移。这些研究表明,原发性肿瘤中长链神经节苷脂的表达增加是与高转移潜力相关的因素之一,也预测了术后早期转移的发展。
The expression patterns of glycolipids of human renal‐cell carcinoma were studied in primary tumors from 23 cases and 5 metastatic lesions from 4 cases using HPTLC (high‐performance thin‐layer chromatography). The expression pattern of glycolipids in primary tumors was characteristic of the histological cell type. In granular‐cell carcinoma, lactosylceramide (CDH), GM3 and the longer‐chain gangliosides (gangliosides migrating more slowly than GM3) increased, although in clear‐cell carcinoma, CDH and other glycolipids tended to decrease. Globoside decreased in all cases but one, irrespective of cell type. In metastatic lesions of the clear‐cell type, the prominent increase in longer‐chain gangliosides was characteristic. Furthermore, the same expression pattern as that of metastastatic lesions was shown in 3 of 14 patients with primary clear‐cell carcinoma, all of whom developed metastases soon after radical nephrectomy. These studies indicate that the increased expression of the longer‐chain gangliosides in primary tumor is one of the factors associated with high metastatic potential, and also predict early post‐operative development of metastasis.
