RT Journal Article SR Electronic T1 Sonic hedgehog, TBX18, and TSHZ3 proteins involved in pyeloureteral motility development are overexpressed in ureteropelvic junction obstruction JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 737 OP 743 DO 10.15537/smj.2016.7.14789 VO 37 IS 7 A1 Yilmaz, Omer A1 Nese, Nalan A1 Dalgic, Mustafa A1 Kesici, Gonca P.

Histopathological and immunohistochemical features for sonic hedgehog (SHH), TBX18, and TSHZ3 of UPJ were evaluated and findings were compared with 20 autopsy cases (group 2).Results: In group 1, the scores were statistically significantly higher in terms of cytoplasmic SHH, nuclear TBX18, cytoplasmic and nuclear TSHZ3 staining. Statistically, no correlation was found between age and the staining scores belonging to these 3 antibodies in group 1 and group 2. Intense inflammation was found to be related with nuclear staining for TBX18.Conclusion: Gene product expressions of SHH, TBX18 and TSHZ3 are statistically higher in patients with UPJ obstruction, when compared with control group. The explanation may be the reactivation of the processes, which had shown their effects in the embryological period, due to the chronic inflammation and long-term micro-trauma created by the disease.
