Abstract:Bax gene as a member of the bcl-2 genes family plays the role of the promotion of apoptosis. In this experiment, Scutellaria baicalensis Georgi cell was transformed with bax gene, the transformed cell treated with 25 and 40 μmol·L-1 estradiol show the features of apoptosis. The browning occurred obviously after 5 days treated with 40 μmol·L-1 estradiol, the features of nucleus marginalization, chromatin pyknosis and the formation of nuclear apoptotic bodies were observed.
