ABSTRACT

OBJECTIVE:

A hedgehog family ligand, namely, sonic hedgehog (SHH), was reported to be important in the development of bladder and ureter smooth muscle. In this prospective study, we aimed to determine protein expression of SHH in resected ureterovesical junction (UVJ) segments of children with vesicoureteral reflux (VUR). MATERIALS AND

METHODS:

The study group included 19 children; 12 (63%) girls, 7 (37%) boys, who had ureteroneocystostomy operation; 3 (15.7%) right sided, 7 (36.8%) left sided, 9 (47.3%) bilateral, due to primary VUR between years 2015 and 2018. Totally, 28 UVJ segments were examined for Western Blot analysis to determine related protein expression levels.

RESULTS:

The mean Western blot band area of SHH gene pathway related protein was 3880.69 (2059.55-13941.61) while the mean area of ß-Actin, the house-keeping gene, was 20180.25 (9530.39-26709.75) (p = 0.001). Correlation analyses between grade of reflux and protein expression of SHH gene pathways revealed no significant relation (p = 0.300). When the UV samples were grouped as low- and high-grade reflux and compared in terms of SHH protein expression levels, no statistically significant difference was found between groups (p = 0.818).

CONCLUSION:

We concluded that SHH signaling molecule which is effective in development of bladder and ureter smooth musculature might also be effective in etiopathology of reflux.
RESUMEN

OBJETIVO:

Se ha informado que el ligando sonic hedgehog (SHH) es importante en el desarrollo de los músculos lisos de la vejiga y el uréter. Nuestro objetivo fue determinar la expresión proteica de SHH en los segmentos de la unión ureterovesical de niños con reflujo vesicoureteral (RVU). MATERIALES Y

MÉTODOS:

El grupo de estudio incluyó a 19 niños; 12 (63%) niñas, 7 (37%) niños, que tuvieron operación de ureteroneocistostomía (UNC); 3 (15.7%) derecho, 7 (36.8%) izquierdo, 9 (47.3%) bilateral, por RVU primario entre los años 2015-2018. Se examinaron un total de 28 segmentos de la unión ureterovesical para análisis de transferencia Western para determinar los niveles de expresión de proteínas relacionadas en las muestras.

RESULTADOS:

El área media de la banda de transferencia Western de la proteína relacionada con la vía del gen SHH fue de 3880.69 (2059.55-13941.61), mientras que el área media de la ß-actina, el gen de limpieza, fue de 20180.25 (9530.39-26709.75) (p = 0.001). Los análisis de correlación entre el grado de reflujo y la expresión de proteínas de las vías del gen SHH no revelaron una relación significativa (p = 0.300).

CONCLUSIÓN:

Concluimos que la molécula de señalización SHH también podría ser efectiva en la etiopatología del reflujo vesicoureteral.
