To examine if cellular autophagy is also dysregulated in DMD satellite cells, we performed ddPCR analysis to assess the expression of a panel of autophagy genes (Atg9a, Atg14, Map1lc3b) in satellite cells freshly isolated from B10, mdx, DBA, and D2-mdx mice. The gene discussed is ATG9A; the disease is Duchenne muscular dystrophy.
