Summary
Poly(ADP-ribose) polymerase (PARP) enzymes regulate DNA repair and metabolism. This review explores PARP
Area of Science:
- Biochemistry and Molecular Biology
- Genetics and Genomics
- Pharmacology and Therapeutics
Background:
- The poly(ADP-ribose) polymerase (PARP) family comprises 17 NAD⁺-dependent enzymes.
- PARP enzymes catalyze ADP-ribosylation, crucial for DNA repair, metabolism, and immune responses.
- Dysregulated PARP activity is linked to various human diseases.
Purpose of the Study:
- To elucidate the structural features and diverse biological roles of PARP family members.
- To explore the implications of PARP dysregulation in physiological and pathological conditions.
- To provide insights into current and future PARP-targeted therapeutic strategies.
Main Methods:
- Comprehensive literature review of PARP family structure and function.
- Analysis of PARP roles in DNA repair, genome stability, and cellular metabolism.
- Examination of PARP involvement in non-oncological diseases and therapeutic potential.
Main Results:
- Detailed classification of PARP family members based on structural and functional characteristics.
- Demonstration of PARP enzymes' critical roles in maintaining genome stability and regulating cellular processes.
- Identification of emerging therapeutic applications for PARP inhibitors beyond oncology.
Conclusions:
- PARP enzymes are vital regulators of fundamental biological processes.
- PARP dysregulation contributes to disease pathogenesis, highlighting therapeutic opportunities.
- Further research into PARP-targeted therapies holds promise for treating diverse conditions.

01:23Negative Regulator Molecules
35.9K
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

02:37DNA Damage can Stall the Cell Cycle
9.3K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

02:23Abnormal Proliferation
4.6K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

01:19Interactions Between Signaling Pathways
6.4K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
