Bax and Bcl-2 expression/ratio remains unaltered following irradiation or AS-miR-31 transfection.
(a) Densitometry of western immunoblots of Bax and Bcl-2 16 h post-irradiation failed to show any change in the Bax or Bcl-2 expression levels or in Bax/Bcl-2 ratio. (b) Similarly, the expression or ratio of Bax/Bcl-2 remained unchanged following pre-treatment with AS-miR-31 prior to irradiation. Immunoblot images are representative of three independent experiments yielding similar results.
