摘要
Polycystic kidney disease is the most common hereditary kidney disorder with early and frequent hypertension symptoms. The mechanisms of cyst progression in polycystic kidney disease remain incompletely understood.Bsg (basigin) heterozygous and homozygous knockout mice were generated using cas9 system, and Bsg overexpression was achieved by adeno-associated virus serotype 9 injection. Renal morphology was investigated through histological and imaging analysis. Molecular analysis was performed through transcriptomic profiling and biochemical approaches.Bsg-deficient mice exhibited significantly elevated arterial blood pressure. Further investigation demonstrated that Bsg deficiency triggers spontaneous cystic formation in mouse kidneys, which shares similar cyst pathological features and common transcriptional regulatory pathways with human polycystic kidney disease. Moreover, Bsg disruption promoted polycystin-1 ubiquitination and degradation, leading to activation of polycystic kidney disease associated cAMP and AMPK signaling pathways in Bsg knockout mouse kidneys. Finally, adeno-associated virus serotype 9 mediated Bsg reexpression reversed cystic progression in Bsg knockout mice in vivo, and Bsg overexpression inhibited the expansion of Madin-Darby canine kidney cysts in vitro.Our findings show that Bsg deficiency leads to an early-onset spontaneous polycystic kidney phenotype, suggesting that dysregulated Bsg signaling may be a contributing factor in cystogenesis.
