Molecular Imaging: PARP-1 and Beyond.

Area of Science:

• Biomedical imaging
• Molecular biology
• Genetics

Background:

• DNA damage is implicated in nearly all diseases, driving pathogenesis.
• DNA repair mechanisms are crucial for maintaining genomic stability.
• Targeting DNA damage response proteins is a key strategy in cancer therapy.

Purpose of the Study:
