To further investigate the effects of miR-145 on the progression of AAA, mice were injected with the corresponding recombinant lentiviruses carrying LV-miR-NC, LV-miR-145, LV-negative control (NC)-inhibitor, and LV-miR-145-inhibitor, respectively, one day after induction of Ang II to ApoE-/- mice. The gene discussed is AGT; the disease is triple-A syndrome.
