Detection of autophagy in Hirschsprung’s disease

Hirschsprung's disease (HD) is a common congenital gastrointestinal malformation, characterized by the lack of ganglion cells from the distal rectum to the proximal bowel, but the pathogenesis is not well understood. This paper evaluates the effects of autophagy in HD. Using electron microscopy, the autophagosomes were detected in three segments: narrow segment (NS), transitional segment (TS), and dilated segment (DS). Typical autophagosome structures are found in the Auerbach plexus of both NS and TS. Real-time PCR results showed that Beclin1 (NS vs. TS, P
