Insights

This study reveals that CHAC1 gene upregulation contributes to kidney stone formation by promoting autophagy-mediated ferroptosis in renal tubular cells. The drug Paliperidone targets CHAC1, inhibiting this process and offering a new kidney stone treatment strategy.

Area of Science:

  • Nephrology
  • Cell Biology
  • Biochemistry

Background:

  • Renal tubular epithelial cell injury is a key factor in kidney stone development.
  • The role of autophagy-mediated ferroptosis in this injury is not well understood.

Purpose of the Study:

  • To investigate the role of CHAC1 in kidney stone formation.
  • To explore the therapeutic potential of Paliperidone in inhibiting autophagy-mediated ferroptosis.

Main Methods:

  • Bioinformatic analysis to identify ferroptosis-related genes.
  • In vitro cell models (HK-2 cells) treated with calcium oxalate (CaOx).
  • CHAC1 gene knockdown via shRNA, protein expression analysis (Western Blot), autophagy and ferroptosis marker detection, molecular docking, and cell thermal migration assays.

Main Results:

  • CHAC1 was found to be upregulated in kidney stones and linked to ferroptosis.
  • CHAC1 knockdown reduced CaOx-induced autophagy and ferroptosis.
  • Paliperidone (Pali) was shown to target CHAC1, inhibit its activity, and reduce autophagy-mediated ferroptosis.

Conclusions:

  • CHAC1 upregulation is associated with kidney stone formation via autophagy-mediated ferroptosis.
  • Paliperidone effectively inhibits this pathway by targeting CHAC1.
  • Targeting CHAC1 offers a novel therapeutic approach for kidney stone treatment.

Indirect-Acting Cholinergic Agonists: Mechanism of Action

Indirect-acting cholinergic agonists work by interacting with an enzyme called acetylcholinesterase (AChE) in the synaptic cleft. They can be reversible or irreversible inhibitors and have different effects on the enzyme.
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex,...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Anticholinesterase Agents: Poisoning and Treatment

Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.     
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Indirect-Acting Cholinergic Agonists: Chemistry and Structure-Activity Relationship

Indirect-acting cholinergic agonists are agents that interact with the acetylcholinesterase enzyme in the synaptic cleft, preventing the breakdown of acetylcholine into choline and acetate. Consequently, the concentration of acetylcholine in the synaptic cleft increases. These agonists can be classified into reversible and irreversible inhibitors based on their duration of action.
Reversible inhibitors display short to medium durations of action. Short-acting agents include simple alcohols with...

Indirect-Acting Cholinergic Agonists: Pharmacokinetics

Indirect-acting cholinergic agonists, or anticholinesterases, enhance the body's cholinergic activity by inhibiting acetylcholine's breakdown. They are categorized as reversible or irreversible agents based on their mechanism of action. They are further classified into short-acting, intermediate-acting, and long-acting agents based on their duration of action.
Reversible agents containing quaternary amines, such as neostigmine and edrophonium, are not easily absorbed orally because they...
