The Promise of Integrins as Effective Targets for Anticancer Agents
Abstract:
This review will briefly describe integrin function, address why integrins are attractive targets for chemotherapeutic drug design, and discuss some ongoing studies aimed at inhibiting integrin activity. Integrins are cell surface heterodimeric receptors. They modulate many cellular processes including: growth, death (apoptosis), adhesion, migration, and invasion by activating several signaling pathways. Many potential chemotherapeutic agents target integrins directly (eg, polypeptides, monoclonal antibodies, adenovirus vectors). These agents may be clinically useful in controlling the metastatic spread of cancer.
Insights
Integrins are cell surface receptors that control cell growth and migration. Targeting these receptors with new drugs shows promise for controlling cancer metastasis.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Integrins are crucial cell surface heterodimeric receptors.
