Roles and therapeutic potential of PARP-1 in neurodegenerative diseases.

Poly(ADP-ribose) polymerase 1 (PARP-1) was first discovered in the 1960 s, and over the past few decades, there has been growing evidence that PARP-1 plays a key role in neurodegenerative diseases such as Parkinson's disease, Alzheimer's disease, Huntington's disease, and amyotrophic lateral sclerosis. With DNA damage detection and repair as its main function, PARP-1 is activated by regulation in the early stages of neurodegenerative diseases, quickly and effectively repairs mild DNA damage, and...
