In contrast, other key nodes in Figure 2C, including FGFR2, FRK, and TEK were not expressed at appreciable levels in MDA-MB-231 (log2(TPM + 1) for TEK: 0.0704, FRK:0.124, FGFR2:0.227), and their expressions were not significantly upregulated in TNBCs compared to other breast cancer subtypes (Figure 2—figure supplement 2). Here, TEK is linked to breast cancer.
