How COSMIC supports exploratory research in cancer drug discovery
Identification of mutations in target genes – COSMIC provides a comprehensive catalog of somatic mutations observed in various cancer types. Researchers can use COSMIC to identify mutations occurring in the gene associated with the drug target. Evaluating the prevalence and distribution of mutations can help assess the potential impact on the function of the target.
Frequency of mutations across cancer types – Analyzing COSMIC data allows researchers to assess the frequency of mutations in the target gene across different cancer types. Higher mutation frequencies in specific cancer types may indicate the relevance of the target in those cancers, supporting its potential as a drug target.
Correlation with clinical data – COSMIC integrates clinical data, including patient outcomes. Researchers can correlate mutations in the target gene with clinical parameters such as patient survival, response to treatment, or disease progression. Positive correlations may suggest the potential significance of the target in predicting clinical outcomes.
Functional impact of mutations – COSMIC provides information on the functional impact of specific mutations. Understanding whether mutations in the target gene are driver mutations (contributing to cancer development) or passenger mutations (incidental changes) is crucial. Driver mutations are more likely to validate the target as a potential therapeutic intervention.
Validation across datasets – Researchers can cross-validate findings from COSMIC by comparing them with data from other sources, such as The Cancer Genome Atlas (TCGA) or other cancer genomics databases. Consistency across multiple datasets strengthens the validity of the target.
Exploration of drug response data – COSMIC includes data on drug response, allowing researchers to explore how cancer cell lines with specific mutations in the target gene respond to different drugs. Assessing drug response data helps predict potential therapeutic strategies and identifies drugs that may be effective against cancers with specific mutations in the target.
Integration with pathway analysis – COSMIC provides information on pathways associated with mutated genes. Researchers can integrate this data with pathway analysis tools to understand the broader biological context of the target. Pathway analysis helps identify potential interactions and dependencies that can further validate the significance of the target.
