The approval label of many drugs specifically states use in cancer of a certain tissue type, for instance, breast or lung. In any approach to precision medicine, cancer lineage should therefore be taken into account. NTRC’s Oncolines™ cancer cell line profiling service1,2 now includes such tissue-type analysis, indicating whether drugs or drug candidates show preferential activity in a certain cancer tissue type. Annotation of disease indication conforms to the Cellosaurus database.3 The associated tissue types are hierarchically organized according to the Oncotree classification.4 Figure 1 shows an example in which Oncolines™ tissue-type analysis reveals that the CDK4/6 inhibitor ribociclib (Kisqali®) potently inhibits proliferation of cell lines of neuroblastoma origin. This finding supports ongoing clinical studies.5

About Oncolines™
NTRC Oncolines™ is a screening service on a panel of 102 cancer cell lines, which enables drug sensitivity analyses, biomarker discovery and the mapping of drug candidates within the competitive field. The panel yields highly reproducible data and captures drug response through various metrics.1,2Gene mutations, copy number variations and gene expression variations can be associated with drug response by bioinformatics. Validation of markers is part of our follow-up workflow. The tissue type boxplot is part of the standard analysis included in Oncolines™ profiling.
