N6-methyladenosine (m6A) regulators decrease during development but increase in cancer, particularly IGF2BP1/2/3, indicating oncofetal reprogramming and guiding cancer therapy.
Area of Science:
- Epigenetics and Molecular Biology
- Developmental Biology
- Cancer Research
Background:
- N6-methyladenosine (m6A) is crucial in human development and cancer.
- Dynamic expression of m6A regulators during human tissue development is poorly understood.
Purpose of the Study:
- To analyze dynamic expression alterations of m6A regulators during human tissue development and cancer.
- To investigate the role of IGF2BP1/2/3 in cancer progression and its association with clinical outcomes.
Main Methods:
- Comprehensive analysis of m6A regulator expression across seven tissue types during development.
- Analysis of m6A regulator expression in eight cancer types.
- Investigation of genome alterations, particularly copy number amplification, affecting IGF2BP1/2/3 expression.
- Clinical association analysis linking IGF2BP1/2/3 expression to patient survival.
- Enrichment analysis of genes correlated with IGF2BP1/2/3 in cancer hallmark pathways.
Main Results:
- m6A regulators generally showed decreased expression during tissue development.
- Insulinlike growth factor 2 MRNA-binding protein 1/2/3 (IGF2BP1/2/3) exhibited a reverse expression pattern, increasing during cancer progression.
- IGF2BP1/2/3 expression was linked to genomic alterations like copy number amplification.
- Higher IGF2BP1/2/3 expression correlated with poorer patient survival.
- Genes associated with IGF2BP1/2/3 were enriched in cancer hallmark pathways.
Conclusions:
- Dynamic expression analysis of m6A regulators provides insights into tissue development and cancer.
- IGF2BP1/2/3's oncofetal reprogramming pattern suggests potential as a therapeutic target in cancer.
