This review examines H19 and IGF2 imprinting mechanisms and their implications in cancer development in embryos, suggesting potential therapeutic strategies.
Key Points
This review explores the imprinting mechanisms of H19 and IGF2 and their role in both development and tumorigenesis.
Review of regulatory mechanisms for H19 and IGF2 imprinting
Analysis of DNA methyltransferases and their role in signaling pathways
Examination of the effects of imprinting loss on cancer development
H19 and IGF2 exhibit opposing roles in development; IGF2 promotes growth while H19 restricts it.
Loss of imprinting at the H19/IGF2 locus disrupts normal function and contributes to tumorigenesis.
H19 overexpression activates pro-cancer pathways like PI3K/AKT, enhancing tumor progression.
