(D) Histochemistry and immunohistochemistry of quadriceps muscle from VCP-RH-expressing transgenic mice. Hematoxylin and eosin (H&amp;amp;E) staining of a 15-mo-old animal with an RV, p62 immunostaining of an RV from a 12-mo-old animal, LC3 immunostaining of an RV, and subsarcolemmal accumulations of LC3 from a 12-mo-old animal. The bracket highlights one LC3-positive myofiber. A single muscle fiber is outlined in white. (C and D) Arrows denote vacuoles or accumulations of p62 or LC3. Bars, 30 µm.
