    How does Hedgehog signaling participate in the cross-interaction of hormones and testis development?

    BIOCELL, Vol.49, No.1, pp. 93-107, 2025, DOI:10.32604/biocell.2024.058299 - 24 January 2025

    Abstract Hedgehog (HH) signaling has been researched for decades and Hedgehog has 3 homologs: Sonic Hedgehog (Shh), Indian Hedgehog (Ihh), and Desert Hedgehog (Dhh). Dhh is the one involved in male gonad and germ cell development. The distribution of molecules in Hedgehog signaling in testis indicated that Hedgehog signaling executes important functions during testis development. The patients with Dhh signaling deficiency develop dysgenesis of gonads and hormone production which demands further exploration of gonad HH signaling. Some results proved the indispensable roles of HH signaling in gonad and germ cell development and the interaction with More > Graphic Abstract

    Mixed gonadal dysgenesis and Denys-Drash syndrome: urologists should screen for nephrotic syndrome

    Canadian Journal of Urology, Vol.14, No.6, pp. 3767-3769, 2007

    Abstract Objective: We present a child with Denys-Drash syndrome recognized after surgery for mixed gonadal dysgenesis, and discuss screening procedures the urologist should consider in similar circumstances.
    Case report: A 1-year-old child with XY gonadal dysgenesis underwent genital reconstruction. The postoperative period was complicated by incisional drainage, which led to the recognition of a nephrotic syndrome. Molecular analysis of the WT-1 gene confirmed a mutation associated with the Denys-Drash syndrome.
    Conclusion: The Denys-Drash syndrome should be suspected in children with XY gonadal dysgenesis. The presence of urine protein should be sought in such children, and if present, consultation More >
