ABSTRACT
Objective:
To investigate the effects of Genistein and Tyrphostin AG1478 on the proliferation of colon cancer cell HT-29 and its possible mechanism.Methods:
The effect of two tyrosine kinase inhibitors (TKIs) on HT-29 cell lines was studied by using MTT assay.Immunocytochemical staining was performed with PCNA polyclonal antibody in HT-29 cells.Western blot assay was used to detect the expression of ERK-1 and pERK.Results:
Both Genistein and Tyrphostin AG1478 significantly inhibit the growth of HT-29 cells and showed concentration dependence.Two tyrosine kinase inhibitors suppressed PCNA expression.Western blot revealed that Genistein and Tyrphostin not inhibit ERK-1 expression but inhibit phosphorylation of ERK.Conclusion:
Tyrosine kinase inhibitors Genistein and Tyrphostin AG1478 can inhibit the growth of HT-29 colon cancer cells,the anti-proliferation mechanism may be related to down-regulate the expression of pERK.
