Figure 1. HERV-K mRNA expression in breast cancer patient tumors.

Figure 1

HERV-K108, K109, K113, and K115 reference genome sequences and gene annotations were downloaded from NCBI GenBank (n = 512). Expression of HERV-K env (a), pro (b), gag (c), and pol (d) was evaluated. (e) HERV-K expression percent by subtype, expressed as the percentage of samples in each subtype above the FPKM median for all subtypes.
