Losartan Inhibits Vascular Smooth Muscle Cell Proliferation through Activation of AMP-Activated Protein Kinase

Kim JE, Choi HC

  • Korean J Physiol Pharmacol.
  • 2010 Oct;14(5):299-304.
  • doi: 10.4196/kjpp.2010.14.5.299
Losartan is a selective angiotensin II (Ang II) type 1 (AT1) receptor antagonist which inhibits vascular smooth muscle cells (VSMCs) contraction and proliferation. We hypothesized that losartan may prevent cell...
