According to the network topology parameters, the BC of neurotrophic receptor tyrosine kinase 1 (NTRK1), tumor protein P53 (TP53), cullin 3 (CUL3), estrogen receptor 1 (ESR1), ubiquitin C (UBC), and EGFR is 12 times greater than the median BC of the whole network (1209), which is predicted to be the core protein acted by bailing tablet. Here, UBC is linked to breast cancer.
