本实验采用ＰＫＣ抑制剂Ｓｔａｕｒｏｓｐｏｒｉｎｅ作用于ＳＡＣＣ－８３系，观察对Ｐ２１ｒａｓ、ｃ－ｍｙｃ表达的影响．结果表明，Ｓｔａｕｒｏｐｏｒｉｎｅ可明显降低Ｈ－ｒａｓ、ｃ－ｍｙｃ表达程度（ｐ＜０．０１），这提示ＰＫＣ对ｒａｓ、ｃ－ｍｙｃ基因表达具有调控作用，ＰＫＣ抑制剂可能通过调控癌基因的表达来表现抗肿瘤作用的．
In this study, PKC inhibitor Staurosporine was used to act on SACC-83 line to observe the effect on the expression of P21ras and c-myc. The results showed that Stauroporine can significantly reduce the expression of H-ras and c-myc (p<0.01), suggesting that PKC regulates the expression of ras and c-myc genes. PKC inhibitors may regulate oncogene expression. Performance of anti-tumor effect.
