Abstract: Abstract: Objective To investigate the relationship between the methylation of RET (proto-oncogene, RET) and
Hirschsprung disease (HD), and understand its significance in the development of intestinal wall ganglion cells. Methods
Twenty-one surgical removal specimens, which were all dilation segment of HD in Tianjin Childrens Hospital, were used as
experimental group, and 5 samples of non-HD normal colon tissues were used as control group. The bisulfite sequencing
(BSP) - direct detecting method was used to detect RET CpG island methylation status. The expression of RET protein was
