Bionano Announces Publication of a Study that Applied OGM to Discovery of Structural Variants Driving Drug Resistance and Sensitivity in Cancer
Genome Variation Signatures. The study compared genome variation signatures obtained from the leukemia samples by OGM and by classical cytogenetic methods including karyotyping (KT) and fluorescence in situ hybridization (FISH).
Drug Resistance & Sensitivity Assay. The study used a cell viability and drug screening assay based on growing leukemia-enriched cell collections in the presence of different concentrations of drug agents to measure cell viability. Cells that grew well in the presence of drugs were determined to be resistant and those that didn’t were determined to be sensitive.
Overall, the study shows that OGM for SV detection combined with drug sensitivity data for the same samples is a useful approach to identifying potentially pathogenic SVs that may be drivers of drug sensitivity or resistance.
Key findings are as follows:
- OGM detected all SVs that had been observed using classical cytogenetic methods as well as multiple additional variants that were not previously reported
- BCR-ABL1 translocated leukemia samples are sensitive to the tyrosine kinase inhibitor Nilotinib, as expected, but exhibit resistance to proteasome inhibitors
- Drug sensitivities associated with previously unreported genomic rearrangements were revealed
- Leukemia samples with KMT2A translocations are associated with drug sensitivities to the microtubule disruptors Paclitaxel and Cabazitaxel and resistance to Bcl-2 family inhibitors
- Chemosensitivity associations with SVs detected by OGM are able to reveal several potential new treatment strategies for leukemia
“This paper represents incredibly well-done research that demonstrates the potential biological and clinical significance of structural variants and the ability of OGM to detect SVs in a reliable and efficient sample to answer workflow. SVs are historically underrepresented in genomics studies due to limitations associated with classical cytogenetic methods and sequencing. We are pleased to see this type of biomarker discovery research and hope it will lead others to conduct more studies, which we believe will help pharmaceutical companies develop better drugs and clinicians provide the right drugs to the right patients,” commented Erik Holmlin, PhD, president and chief executive officer of Bionano.
