    • Abstract
  • The methylation rate of P16 gene in colon cancer cell lines, colonic cancer tissue and norm al colonic mucosa were examined by Southern blot method. T he data showed that aberrant methylation of 5' CpG island of P16 gene was observed in5 of 6(83.3%)colon cancer cell lines, 13 of 18(72. 2%)colon cancer tissue.In contrast,only 5 of 18(27.8%)normal colonic mucosa showed aberrant methylation of the 5'CpG island of P16 gene.The results suggest that P16 gene in colon cancer was inactivated by aberrant methylation.This can provide a new tactics and a new target for colon's gene therapy.
