ABSTRACT
Objective Investigate the effect of TrKA variation on the expression of neucleoprotein NF-?B P65 and apoptosis.Methods To construct the expression vector of TrKA small interfering RNA,the recombinant was transfected into MCF-7 cells.the stable cell line expressing TrKA small interfering RNA were selected by G418.The mRNA and protein of TrKA were tested by real-time PCR,Western-blot and Immunohistochemistry.The change of neucleoprotein NF-?B P65 was detected by WB,Flow cytometry was used to observe the cell apoptosis.ResultsThe expression vector of TrKA-siRNA was successfully constructed.The mRNA and protein of TrKA were decreased by 74.7% and 80.5% respectively(P
