Insights

Stem/progenitor cells CD133(+)CD24(+) are involved in Autosomal dominant polycystic kidney disease (ADPKD) progression. These cells are more abundant in ADPKD kidneys, suggesting a role in pathogenesis.

Area of Science:

  • Nephrology
  • Stem Cell Biology
  • Pathogenesis of Kidney Diseases

Background:

  • Autosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive kidney cyst development.
  • Renal tubules normally repair damage using stem/progenitor cells (CD133(+)CD24(+)).
  • Insufficient repair in ADPKD suggests a potential role for these stem cells in disease progression.

Purpose of the Study:

  • To investigate the localization and involvement of CD133(+)CD24(+) cells in ADPKD progression.
  • To determine if these progenitor cells contribute to the pathogenesis of ADPKD.

Main Methods:

  • Analysis of normal and ADPKD kidney tissues.
  • Confocal microscopy and immunoblotting to assess CD133 and CD24 expression.
  • Quantification of CD133(+)CD24(+) cells in renal tissues.

Main Results:

  • CD133 and CD24 expression was observed in a subset of epithelial cells in both normal and ADPKD kidneys.
  • These cells are located in Bowman's capsule and the luminal side of tubules.
  • CD133(+)CD24(+) cells were significantly more represented in ADPKD tubules and healthy glomeruli.
  • ADPKD cysts also expressed CD133 and CD24.

Conclusions:

  • Renal epithelial progenitors (CD133(+)CD24(+)) are involved in ADPKD pathogenesis.
  • Further research is needed to clarify their precise role.
  • Targeting these cells may offer a strategy for disease management and stabilization.

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...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Cytoskeletal Linker Proteins - Plakins

Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...

cAMP-dependent Protein Kinase Pathways01:25

cAMP-dependent Protein Kinase Pathways

Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...
