Summary
During human brain development, oxidative stress and lipid peroxidation (LPO) are physiological processes. These processes target specific proteins during active myelination, impacting brain maturation.
Area of Science:
- Neuroscience
- Developmental Biology
- Biochemistry
Background:
- Human cerebral myelination involves rapid cellular membrane production.
- This process may be accompanied by physiological free radical generation and lipid peroxidation (LPO).
Purpose of the Study:
- To investigate oxidative stress markers in developing human parietal white matter.
- To identify proteins modified by LPO during active myelination.
Main Methods:
- Used 4-hydroxy-2-nonenal (HNE) protein adducts as an indicator of LPO.
- Employed immunocytochemistry and Western blotting to detect HNE-modified proteins.
- Utilized mass spectrometry to identify specific HNE-modified proteins.
Main Results:
- Increased HNE-positive glia observed from 40 gestational weeks to 1.5 postnatal years.
- Distinct patterns of HNE-modified proteins identified in fetal/term versus later developmental stages.
- Cytoskeletal proteins (tubulins, neurofilaments), oligodendrocyte/astrocyte proteins, and cell cycle/metabolism proteins were prominently modified by HNE during active myelination.
Conclusions:
- Human brain development involves basal oxidative stress and LPO.
- These oxidative processes target different proteins in an age-specific manner.
- Age-specific LPO likely plays distinct roles in different periods of brain maturation.
