Abstract:
Objective To investigate the effect of tea polyphenols and sulforaphane on the expression of protein kinase A anchoring protein 95 and cyclin E2 in lung cancer tissue.Methods 56 cases confirmed by pathology and operation therapy for lung cancer patients,were randomly divided into combined treatment group and control group,each had 28 cases.The content of protein kinase A anchoring protein 95 and cell cycle protein E2 in all patients were determined with ELISA.The expression of protein kinase A anchoring protein 95,cyclin E2 and statistics of microvessel density(MVD) were detected by immunohistochemical SP method.The protein levels of protein kinase A anchoring protein 95 and cell cycle protein E2 protein were detected by Western Blot. Results The contents of protein kinase A anchoring protein 95 and cyclin E2 in control group were higher than that in combination group,the differences were statistically significant(P<0.01 ).Immunohistochemical SP results showed that protein kinase A anchoring protein 95 and cyclin E2 expression all had positive expression,and the MVD in control group was higher than combination group(P<0.01);Western Blot results showed that the expressions of protein kinase A anchoring protein 95 and cyclin E2 protein in control group were higher than combination group(P<0.01).Conclusion Protein kinase A anchoring protein 95 and cyclin E2 expressions are increased in both groups in lung cancer tissues,and they are positively correlated,negatively correlated with drug treatment,which can be used as the indexes of lung cancer evaluation.
