First, the follow-up data of patients with all pathological types of BC were downloaded from the TCGA dataset, and then we matched the lnc-TRDMT1-5 expression profile downloaded from 587 invasive BC patients from the TCGA database to detect its expression levels (Figure 5E; total number of BC patients was 589, two duplicates were removed) with those samples containing the follow-up survival data. This evidence concerns the gene TRDMT1 and breast cancer.
