ADP (adensine diphosphate) A nucleotide consisting of adenine and ribose with two phosphate groups attached. The second phosphate is attached to the first by a high-energy bond.
Objective: To observe the expression of poly (ADP-ribose) polymerase (PARP) in focal cerebral ischemia with reperfusion injury and explore the role of PARP in apoptosis.
The cleavage of Poly(ADPribose)polymerase(PARP) is an molecular event of the activation of cysteine protease, and it is also an early molecular marker of apoptosis .
