Beyond transcription: RNA-binding proteins steering angiogenesis

Area of Science:

• Vascular Biology
• Molecular Biology
• Gene Regulation

Background:

• Angiogenesis, the formation of new blood vessels, is vital for development, repair, and cancer.
• Endothelial cell (EC) migration and proliferation, driven by angiogenic factors, orchestrate this process.
• RNA-binding proteins (RBPs) posttranscriptionally regulate gene expression, influencing cell behavior.

Purpose of the Study:

• To review current findings on the roles of RBPs in angiogenesis.
• To identify knowledge gaps concerning RBP regulation of angiogenic gene pathways.
• To focus on the molecular mechanisms by which RBPs modulate target messenger RNAs (mRNAs).

Main Methods:

• Literature review of recent studies on RBPs and angiogenesis.
• Analysis of RBP interactions with canonical and modified mRNAs.
• Focus on molecular mechanisms of RBP-mRNA regulation in endothelial cells (ECs) and non-ECs.

Main Results:

• RBPs significantly modulate angiogenic gene pathways in both ECs and non-ECs.
• RBPs recognize and regulate both canonical and chemically modified mRNAs.
• Specific molecular mechanisms of RBP-mRNA regulation in angiogenesis are highlighted.

Conclusions:

• RBPs are critical regulators of gene expression in angiogenesis.
• Further research into RBP-mRNA interactions is needed to fully understand their role in vascular biology.
• Understanding these mechanisms can offer insights into therapeutic strategies for angiogenesis-related diseases.
