These «
tumor subclones» are often very relevant as the tumor evolves (especially during treatment).
Not exact matches
But
tumors from patients with distant metastases to the lung and liver showed massive epigenetic changes that mapped to large, blocklike segments of the genome, both in the distant metastases themselves and in the section, or «
subclone,» of the primary
tumors they came from.
The mammary
tumors frequently contained two distinct
subclones — one produced Wnt1 while the other did not.
Thus, two
subclones of the
tumor in AML35 both acquired activating mutations of IDH2 at the same residue but by different mutations.
These findings reinforce many things that we already know: that mutations acquire gradually with age, that most of the mutations in AML (and likely other
tumors) are random background events not contributing to tumorigenesis, and that subsequent mutation and evolution can give rise to
subclones that ultimately determine cancer progression and response to therapy.
Whether identifying rare
subclones missed by standard bulk sequencing, or identifying co-mutation patterns in
subclones, Tapestri Single - Cell DNA Panels can be applied across a wide number of applications, including hematologic malignancies, solid
tumor profiling, and genome editing programs.
