Cancer arises from genetic mutations. Molecularly targeted drugs offer specific cancer treatments by targeting abnormal genes and proteins, but their effectiveness requires predictive diagnostics like DNA microarrays.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Cancer develops due to genetic abnormalities, including oncogene activation and tumor suppressor gene inactivation.
- Current treatments lack effective genomic correction techniques.
- Molecular analyses reveal cancer-specific targets like abnormal gene products, signaling pathways, and cell surface antigens.
Purpose of the Study:
- To review the development and application of molecularly targeted drugs in cancer treatment.
- To highlight the specificity and potential limitations of these targeted therapies.
- To emphasize the need for predictive diagnostics in guiding treatment decisions.
Main Methods:
- Review of molecular biological analyses identifying cancer-specific targets.
- Description of molecularly targeted drugs designed to inhibit specific molecules (mRNA, protein).
- Discussion of the role of host cell targets, such as angiogenic factor receptors.
Main Results:
- Molecularly targeted drugs exhibit higher specificity for cancer cells compared to conventional chemotherapy.
- These drugs can suppress key molecules essential for cancer maintenance.
- Some targeted therapies may stabilize tumors rather than eliminate them.
- Targeted drug efficacy is dependent on target expression and functional importance in cancer.
Conclusions:
- Molecularly targeted drugs represent a significant advancement in cancer therapy due to their specificity.
- Predictive molecular techniques, such as DNA microarrays, are crucial for determining appropriate patient selection and optimizing treatment outcomes.
- Further research is needed to refine genomic correction strategies and enhance the efficacy of targeted therapies.

Drug Discovery: Overview
Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
