We cloned a full-length rat TM5/TM30nm cDNA. Using this cDNA as a probe, we demonstrated that expression of TM5/TM30nm mRNA was higher in the tumorigenic rat fibroblastic cell lines SR-3Y1-2 and fos-SR-3Y1-202 than in the normal cell line 3Y1. High expression of TM5/TM30nm protein in SR-3Y1-2 and fos-SR-3Y1-202 cells was also detected by Western blot analysis using anti-TM5/TM30nm antiserum. In addition, the cellular localization of this protein differed between 3Y1 cells and tumorigenic ones. These findings suggest that TM5/TM30nm is involved in malignant transformation of rat fibroblastic cells.
我们克隆了大鼠TM5/TM30nm的全长cDNA。以该cDNA为探针,我们证明,在致瘤性大鼠成纤维细胞系SR-3Y1-2和fos-SR-3Y1-202中,TM5/TM30nm mRNA的表达高于正常细胞系3Y1。使用抗TM5/TM30nm抗血清进行蛋白质免疫印迹分析,也检测到SR-3Y1-2和fos-SR-3Y1-202细胞中TM5/TM30nm蛋白的高表达。此外,该蛋白在3Y1细胞和致瘤性细胞中的细胞定位有所不同。这些发现表明,TM5/TM30nm参与大鼠成纤维细胞的恶性转化。
