Mission Bio’s Tapestri Platform Helps Understand Cancer Therapy Resistance in New Solid Tumor Study

Single-cell DNA sequencing using solid tissue reveals genetic mechanisms of therapy resistance in melanoma


SOUTH SAN FRANCISCO, June 24, 2021 — Mission Bio, the life sciences company delivering single-cell resolution multi-omics tools to accelerate discoveries and improve time-to-market for new therapeutics, revealed that a recently published paper in Cancer Cell made use of its Tapestri Platform to profile samples taken from melanoma for the first time. This milestone comes on the heels of another paper demonstrating Tapestri’s use in solid tissue, recently published in Nature, and further demonstrates the continued growth in use of Tapestri protocols for solid tissue analysis.


“Mission Bio was founded on a commitment to eliminate cancer in all its forms — and with recent studies proving the Tapestri Platform’s value in solid tissue and solid tumor analysis, we are seeing the capabilities of our tools expand to further support that commitment,” said Yan Zhang, CEO, Mission Bio. “We are continuing to develop and support new applications of our Tapestri technology, and look forward to seeing more progress made from our customers at the frontier of solid tumor studies as our capabilities grow.” 


The study, led by Jean-Christophe Marine, PhD, Science Director at the Centre for Cancer Biology, VIB, Belgium, looks at the role genetic and non-genetic mechanisms of resistance play in BRAF-mutant melanoma after treatment with the combination therapy dabrafenib-trametinib. To understand the genetic mechanisms of resistance, the team performed bulk sequencing, as well as single-nuclei sequencing from melanoma samples, using the Tapestri Platform. The team found the presence of an acquired NRAS resistance-conferring mutation in one sample. Tapestri analysis confirmed that this mutation was not pre-existing, but acquired during treatment.


“These findings have significant implications for the potential treatment of therapy-resistant melanoma,” said Marine, “and could lead to personalized therapies, which may be the best way to treat minimal residual disease. Single-cell analysis using the Tapestri Platform played a vital part in helping us assess mechanisms of resistance in melanoma.”
