Insulin-like growth factor 2 mRNA-binding proteins (IGF2BPs): post-transcriptional drivers of cancer progression?

Area of Science:

• Molecular Biology
• Developmental Biology
• Cancer Biology

Background:

• Insulin-like growth factor-2 mRNA-binding proteins (IGF2BPs) 1, 2, and 3 are oncofetal proteins involved in fundamental cellular processes.
• These proteins are highly expressed during embryogenesis but typically downregulated in adult tissues.
• Re-expression of IGF2BP1 and IGF2BP3 is observed in aggressive cancers, suggesting a role in tumorigenesis.

Purpose of the Study:

• To review the multifaceted roles of IGF2BPs in both embryonic development and cancer biology.
• To explore the correlation between IGF2BP functions during embryogenesis and their involvement in cancer progression.
• To highlight IGF2BPs as potential therapeutic targets in oncology.

Main Methods:

• Literature review of existing studies on IGF2BPs.
• Analysis of IGFBP expression patterns in embryonic and cancerous tissues.
• Examination of IGF2BP involvement in cellular processes like migration, polarization, and differentiation.
• Discussion of regulatory mechanisms, including microRNAs and transcription factors.

Main Results:

• IGF2BPs regulate critical developmental processes such as nerve cell migration and morphological development.
• In cancer cells, IGF2BPs influence cell polarization, adhesion, and migration.
• IGF2BPs are associated with cancer metastasis and the expression of oncogenic factors like KRAS and MYC.
• Their precise pro-metastatic role in vivo requires further investigation.

Conclusions:

• IGF2BPs play conserved roles in development and cancer, particularly in cell migration and metastasis.
• Dysregulation of IGF2BPs contributes to aggressive cancer phenotypes.
• Further research into the in vivo functions of IGF2BPs is warranted to fully exploit their potential as cancer therapeutic targets.
