SM22α Loss Contributes to Apoptosis of Vascular Smooth Muscle Cells via Macrophage-Derived circRasGEF1B

Figure 1

Macrophage infiltration and VSMC apoptosis increase in the aortic media of Sm22α-/- mice with Ang II infusion. All mice were infused with saline (Ang II-) or Ang II (Ang II+) for 4 weeks. (a, b) Representative immunostaining of CD68 and CD14 in the abdominal aortas from WT or Sm22α-/- mice. Bars: 50 μm (a) or 100 μm (b). (c) Representative immunohistochemical staining of TUNEL and SM α-actin in abdominal aortas of WT and Sm22α-/- mice. Data are presented as of three independent experiments. , , and .
