Abstract:
Polycystic kidney disease (PKD) is one of the most common genetic kidney diseases, characterized by the formation of fluid-filled renal cysts, which eventually lead to end-stage renal disease. Despite several decades of investigation, explicit molecular and cellular mechanisms underpinning renal cyst formation have been unresolved until recently, severely hampering the development of effective therapeutic approaches. Currently, most PKD therapies have been developed for limiting disease complications, such as hypertension. Although Tolvaptan has been approved for treating PKD in few countries, the associated hepatic toxicity remains a major concern. In this Review, we will discuss recent advances in PKD research, covering aspects ranging from newly identified genetic/epigenetic causes, increment in mechanistic interpretation, novel therapeutic targets, to the promises offered by emerging stem cell technologies.
Insights
Polycystic kidney disease (PKD) research is advancing, revealing new genetic causes and molecular mechanisms. This progress offers hope for novel therapies beyond managing symptoms and addressing concerns with current treatments.
Area of Science:
- Nephrology
- Genetics
- Molecular Biology
Background:
- Polycystic kidney disease (PKD) is a common genetic disorder leading to kidney failure.
- Current treatments primarily manage complications like hypertension, with limited disease-modifying options.
- Tolvaptan shows promise but has significant hepatic toxicity concerns.
Purpose of the Study:
- To review recent breakthroughs in understanding PKD.
- To highlight novel molecular and cellular mechanisms of renal cystogenesis.
- To discuss emerging therapeutic targets and stem cell applications for PKD.
Main Methods:
- Review of recent scientific literature on Polycystic Kidney Disease.
- Analysis of genetic, epigenetic, and mechanistic studies.
- Evaluation of current and novel therapeutic strategies.
Main Results:
- Identification of new genetic and epigenetic factors contributing to PKD.
