Single nucleotide variant profiles of viable single circulating tumour cells reveal CTC behaviours in breast cancer.

ABSTRACT: Circulating tumour cell (CTC) behaviours are distinct from those of bulk tissues. Thus, treatments to eliminate CTCs differ from the regimens followed to reduce the primary tumour and its metastases. Accordingly, comprehensively deciphering the single nucleotide variant (SNV) profiles in CTCs, which partially determine CTC behaviours, is a priority. Using viable CTCs isolated with the oHSV1‑hTERT‑GFP virus coupled with fluorescence‑activated cell sorting (FACS), the whole genome was amplified using the multiple annealing and looping‑based amplification cycle (MALBAC) method. CTC behaviours were evaluated using the SNVs found to be recurrently mutated in different cells (termed CTC‑shared SNVs). Analysis of the sequencing data of 11 CTCs from 8 patients demonstrated that SNVs accumulated sp
