Type:
Poly (ADP-ribose) polymerase (PARP) cleavage is a hallmark of caspase activation. PARP (Poly (ADP-ribose) polymerase) is a family of proteins involved in a variety of cellular processes, including DNA repair, genomic stability, and programmed cell death. PARP enzymes play a crucial role in repairing single-strand breaks in DNA.
PARP has gained significant attention, particularly in the treatment of certain types of tumors, such as those with BRCA1 or BRCA2 mutations. These mutations impair the cell's ability to repair double-strand breaks in DNA through homologous recombination. Cancer cells with these mutations can become reliant on PARP for survival, making them particularly sensitive to PARP inhibitors.
PARP inhibitors, such as olaparib, rucaparib, and niraparib, have been developed as targeted therapies for cancers associated with BRCA mutations.

PARP Family:
The poly (ADP-ribose) polymerases (PARPs) are a family of enzymes involved in a number of cellular processes, including DNA repair, genomic stability, and programmed cell death.
PARP1 is the predominant family member responsible for detecting DNA strand breaks and initiating repair processes, especially through base excision repair (BER).

PARP1 Overexpression:
In several cancer types—including breast, ovarian, prostate, and lung cancers—elevated PARP1 expression and/or activity has been reported.
High PARP1 expression in certain cancers has been associated with aggressive tumor behavior and resistance to therapies (especially those that induce DNA damage).
Increased PARP1 activity may correlate with poorer overall survival in tumors that rely on DNA repair for survival.
