Summary
Altered phosphoinositide metabolism is linked to autism spectrum disorders. Targeting phosphoinositide 3-kinases offers potential therapeutic strategies for certain autism forms.
Area of Science:
- Cell Biology
- Neuroscience
- Biochemistry
Background:
- Phosphoinositides regulate critical cellular functions like signal transduction and membrane identity.
- Their metabolism involves tightly regulated phosphoinositide kinases and phosphatases.
- Dysregulation of these enzymes is increasingly implicated in autism spectrum disorders (ASDs).
Purpose of the Study:
- To review genetic and functional studies linking phosphoinositide metabolism defects to autism.
- To summarize preclinical research on targeting phosphoinositide 3-kinases (PI3Ks) in neurological diseases.
- To discuss the potential of phosphoinositide metabolism as a therapeutic target for autism.
Main Methods:
- Review of genetic and functional studies in autism and related disorders.
- Analysis of published preclinical work on PI3K inhibitors in neurological conditions.
- Discussion of translational challenges from preclinical models to human applications.
Main Results:
- Evidence suggests PI3Ks and their subunits are frequently affected in ASDs.
- Specific ASDs like fragile X syndrome and PTEN mutations involve defective phosphoinositide metabolism.
- Idiopathic autism forms may also exhibit altered phosphoinositide kinase/phosphatase activity.
Conclusions:
- Altered phosphoinositide metabolism represents a promising therapeutic target for specific autism subtypes.
- Existing PI3K inhibitors developed for cancer offer a starting point for neurological applications.
- Translating these findings into clinical treatments requires addressing significant challenges.

Inborn Errors of Metabolism
990
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Autism Spectrum Disorder
1.6K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Phosphoinositides and PIPs
10.5K
Phosphoinositides are a group of phospholipids containing a glycerol backbone with two fatty acid chains and a phosphate attached to a myoinositol sugar ring. The inositol head group extends into the cytoplasm, where it is modified by adding phosphate groups to form phosphatidylinositol phosphates or PIPs.
Different phosphoinositides are synthesized and recruited on the cytosolic face of the plasma membrane. The localization of specific phosphoinositides concentrated in separate membrane...

Lysosomal Hydrolases
4.7K
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,...

Notch Signaling Pathway
6.8K
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...

Protein Import into the Peroxisomes
5.6K
Cells contain membrane-bound organelles called peroxisomes that oxidize organic molecules by transferring hydrogen atoms to oxygen, producing hydrogen peroxide. Peroxisomes enzymatically convert the released hydrogen peroxide into water and oxygen.
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
