As shown in Figure 1A, breast tumors demonstrated significant overexpression of EDB-FN (median 36.319 transcripts per million (TPM)), compared to normal breast tissues (median 2.410 TPM), translating to an extremely significant log2 fold increase of 3.452 (adj p value = 6.57 × 10−69) in breast cancer over normal tissues. Here, FN1 is linked to breast cancer.
