Abstract:
Defects in rat sarcoma viral oncogene homolog (RAS)-extracellular signal regulated kinase (ERK) and phosphatidylinositol 3-kinase (PI3K)-mammalian target of rapamycin (MTOR) signaling pathways have recently been shown to cause several genetic disorders classified as neuro-cardio-facial-cutaneous (NCFC) and Hamartoma syndromes. Although these pathways are well-known players in cell proliferation and cancer, their role in cognitive function is less appreciated. Here, we focus on the cognitive problems associated with mutations in the RAS-ERK and PI3K-MTOR signaling pathways and on the underlying mechanisms revealed by recent animal studies. Cancer drugs have been shown to reverse the cognitive deficits in mouse models of NCFC and Hamartoma syndromes, raising hopes for clinical trials.
Insights
Defects in RAS-ERK and PI3K-MTOR pathways cause neurodevelopmental disorders. Cancer drugs show promise in reversing cognitive deficits in mouse models, offering hope for new treatments.
Area of Science:
- Neuroscience
- Genetics
- Oncology
Background:
- Genetic disorders like neuro-cardio-facial-cutaneous (NCFC) and Hamartoma syndromes are linked to defects in RAS-ERK and PI3K-MTOR signaling pathways.
- While these pathways are known for their roles in cell proliferation and cancer, their impact on cognitive function is less understood.
Purpose of the Study:
- To investigate the cognitive impairments associated with mutations in the RAS-ERK and PI3K-MTOR signaling pathways.
- To explore the underlying mechanisms of these cognitive deficits using insights from recent animal studies.
Main Methods:
- Review of recent animal studies focusing on RAS-ERK and PI3K-MTOR signaling pathways.
- Analysis of cognitive function in mouse models of NCFC and Hamartoma syndromes.
Main Results:
- Mutations in RAS-ERK and PI3K-MTOR pathways are associated with significant cognitive problems.
- Cancer drugs targeting these pathways have demonstrated the ability to reverse cognitive deficits in preclinical models.
Conclusions:
- The RAS-ERK and PI3K-MTOR pathways play a crucial role in cognitive function.
- Targeting these pathways with existing cancer drugs may offer a therapeutic strategy for cognitive impairments in related genetic disorders.
- These findings support the potential for clinical trials to test cancer drugs for treating cognitive deficits in NCFC and Hamartoma syndromes.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
