Expression and clinical significance of Numb and Notch-1 proteins between tissue of colon cancer and regional lymph node metastases

Numb expression is decreased and Notch-1 expression is increased in colon cancer tissue and metastatic lymph node tissue, suggesting that the interaction between the two proteins may play a promote role in the development, invasion, and metastasis of colon cancer. There was no relationship between the expression of Numb and Notch-1 protein in colon cancer and metastatic lymph node tissue, suggesting that there is no obvious enhancement of the cancer cells; in the process of lymph node metastasis, the degree of malignant biological behavior remains relatively stable.
