PARP Family: Key Regulators of Genome Stability and Translational Therapeutic Potential

Exclusive Literature-Based Review by ANT BIO PTE. LTD.

1. Literature Information

This review systematically summarizes and interprets peer-reviewed publications focusing on the molecular functions, regulatory mechanisms, and translational applications of the Poly(ADP-ribose) polymerase family. The analyzed literature covers the discovery of PARP family members, their structural and functional characterization, roles in DNA damage repair, cell fate decisions, and implications in human diseases including cancer, neurodegenerative disorders, and cardiovascular diseases.

2. Research Background

Genome stability is essential for normal cellular function and survival. Cells constantly encounter intrinsic and extrinsic stresses that cause DNA lesions, including single-strand breaks and double-strand breaks. Failure to repair these lesions leads to genomic instability, which drives aging, inflammation, and various human diseases. The PARP family has emerged as a central regulator in the DNA damage response network, governing multiple repair pathways and coordinating cellular stress adaptation. Deregulation of PARP activity contributes to the pathogenesis of cancer, neurodegeneration, and metabolic disorders, making the PAR family a high-priority target for translational intervention.

3. Research Approach

This study adopts a comprehensive literature mining and systematic interpretation strategy. It integrates structural biology, molecular signaling, cellular functional assays, and disease model studies to clarify the molecular architecture of PARP family members, their catalytic mechanisms, downstream signaling networks, and functional outputs in normal physiology and pathological conditions. It further evaluates the translational value of PARP-targeted strategies in disease models and clinical settings.

4. Research Outcomes

The PARP family constitutes a class of essential enzymes that catalyze the reversible ADP-ribosylation modification of target proteins. PARP1 and PARP2 are the best-characterized members, which localize to the nucleus and function as core sensors of DNA strand breaks. Upon activation, PARP1 medi the formation of poly(ADP-ribose) chains, which serve as a scaffold to recruit downstream repair factors including XRCC1 and DNA polymerase β, thus promoting the repair of single-strand breaks. PARP also participates in double-strand break repair pathways and regulates cell cycle progression, apoptosis, and inflammatory responses. Overactivation of PARP leads to depletion of cellular NAD+ and ATP, which triggers cell death pathways and contributes to neuronal damage and cardiovascular injury. In cancer, PARP overactivation supports uncontrolled proliferation and genome maintenance, while PARP inhibitors exert synthetic lethal effects in repair-deficient tumor cells.
