PARP1 Gene Editing    

PARP1 (poly(ADP-ribose) polymerase-1) is a well-known enzyme as ADP-ribosylation, which is essential for initiating various forms of DNA repair (Table 1). PARP1 becomes activated upon binding to DNA single-strand and double- Strand breaks (ssDB and dsDB respectively). This interaction is important for DNA repair because auto-ribosylation is required for assembly and activation of multiprotein complexes for this process. In addition to DNA repair, the importance of PARP1 as a transcriptional regulator has also been well documented. As an enzyme, PARP1 acts on the chromatin remodeling complex to control DNA-free RNA polymerase. PARP1 also regulates gene expression by acting as a transcription factor binding to the octamer motif of the promoter element. Therefore, PARP1 is involved in cell differentiation, proliferation, and tumor transformation by affecting DNA repair and transcriptional regulation. Moreover, PARP1 gene may be a mutation site in Fanconi anemia and may be involved in the pathophysiology of type 1 diabetes. PARP1 can also counteract the production of reactive oxygen species, which can extend life by inhibiting oxidative damage to DNA and proteins.

DNA Repair Mechanism	PARP1 Function
Base excision repair (BER)	Binds AP site
	Auto-modified PARP1 recruits BER complex
Nucleotide excision repair (NER)	ADP-ribosylates XPA
Mismatch repair (MMR)	ADP-ribosylates MSH6
Single-strand break repair (SSBR)	Auto-modified PARP1 recruits BER complex
Double-strand break repair by nonhomologous end-joining (NHEJ)	Ku enhances PARP1 ADP-ribosylation activity
	ADP-ribosylates and activates DNA-PKcs
Double-strand break repair by homologous recombination (HR)	Auto-modified PARP1 recruits Mre11
	PAR activates ATM signaling

In the treatment of diseases, due to the characteristics of PARP1 in various DNA repair pathways and maintains the characteristics of genomic stability, it is expected to use small molecules inhibiting the enzyme activity to prevent unwanted DNA repair in the treatment of various cancers, including ovarian cancer, breast cancer, and prostate cancer. Understanding the role of PARP1 in maintaining genomic integrity is important not only for the design of novel chemotherapeutic agents but also for understanding the mechanisms of chemical resistance in cancer cells.
