Insights

Renal cystic diseases, a leading genetic cause of kidney failure, may stem from defects in planar cell polarity (PCP) and cilia. This review explores these links and clinical features.

Area of Science:

  • Nephrology
  • Genetics
  • Cell Biology

Background:

  • Renal cystic diseases are a significant clinical issue and the primary genetic cause of end-stage renal disease.
  • Identifying causative genes has not fully elucidated the mechanisms of cyst formation.
  • Recent studies suggest links between cystogenesis and defects in planar cell polarity (PCP) and cilia.

Purpose of the Study:

  • To review the clinical features of renal cystic diseases.
  • To discuss current research connecting cystic kidney disease mechanisms to PCP and cilia.

Main Methods:

  • Literature review of recent research in model organisms.
  • Analysis of clinical features of renal cystic diseases.
  • Synthesis of findings linking genetic mutations to cellular mechanisms.

Main Results:

  • Cyst formation in the kidneys is increasingly associated with disruptions in planar cell polarity pathways.
  • Ciliary dysfunction is also implicated as a key factor in the development of renal cysts.
  • Understanding these molecular pathways offers new insights into disease mechanisms.

Conclusions:

  • Planar cell polarity (PCP) and ciliary function are critical for normal kidney development and maintenance.
  • Defects in PCP and cilia represent promising targets for understanding and potentially treating renal cystic diseases.
  • Further research is needed to fully elucidate the complex interplay between these pathways in human disease.

Microtubules in Signaling01:22

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...
Cytoskeletal Coordination in Cell Migration01:32

Cytoskeletal Coordination in Cell Migration

A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker proteins that...
Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
Cell Polarization by Rho Proteins01:21

Cell Polarization by Rho Proteins

Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...
