CDK inhibition and cancer therapy

Abstract:
The cell-division cycle is a tightly controlled process that is regulated by the cyclin/CDK family of protein kinase complexes. Stringent control of this process is essential to ensure that DNA synthesis and subsequent mitotic division are accurately and coordinately executed. There is now strong evidence that CDKs, their regulators, and substrates are the targets of genetic alteration in many human cancers. As a result of this, the CDKs have been targeted for drug discovery and a number of small molecule inhibitors of CDKs have been identified.
Insights
The cell-division cycle relies on cyclin/CDK complexes for control. Genetic alterations in these complexes are linked to cancer, driving the development of targeted CDK inhibitors for drug discovery.
Area of Science:

- Cell Biology
- Oncology
Background:
- The cell-division cycle is a fundamental biological process.
- Regulation involves cyclin-dependent kinases (CDKs) and their partners.
- Precise cell cycle control is crucial for preventing errors in DNA replication and cell division.
Purpose of the Study:
- To highlight the critical role of cyclin/CDK complexes in cell cycle regulation.
- To underscore the significance of CDKs, their regulators, and substrates as targets in human cancers.
- To emphasize the ongoing efforts in drug discovery targeting CDKs.
Main Methods:
