Insights
Neonatal undernutrition does not affect lacticodehydrogenase isoenzymes in the cerebral cortex. This contrasts with hypothyroidism, which is known to retard their development.
Area of Science:
- Biochemistry
- Neuroscience
- Developmental Biology
Context:
- Lactate dehydrogenase (LDH) isoenzymes play crucial roles in cellular energy metabolism.
- Understanding their developmental trajectory is vital for assessing brain development.
- Cerebral cortex development is sensitive to nutritional and hormonal factors.
Purpose:
- To investigate the impact of neonatal and post-natal undernutrition on the developmental profile of lactate dehydrogenase (LDH) isoenzymes in the cerebral cortex.
- To compare the effects of undernutrition with known effects of hypothyroidism on LDH isoenzyme development.
Summary:
- Starch gel electrophoresis was used to analyze the developmental profile of LDH isoenzymes in the cerebral cortex.
- Results indicate that neither neonatal nor post-natal undernutrition significantly retards the developmental progression of LDH isoenzymes.
- This finding contrasts with the known retarding effect of hypothyroidism on the same developmental parameters.
Impact:
- Provides novel insights into the specific resilience of cerebral cortex LDH isoenzyme development to nutritional deficits.
- Highlights the distinct etiological pathways influencing brain development, differentiating nutritional from hormonal influences.
- Suggests potential targets for therapeutic interventions aimed at mitigating developmental delays in the brain.
Abstract:
The developmental profile of the isoenzymes of lacticodehydrogenase of cerebral cortex, investigated by starch gel electrophoresis, is not retarded during neo and post-natal undernutrition, although hypothyroidism is known to do so.
