Breast cancer tissue microarrays (No. HBreD140Su06) harboring clinicopathological characteristics, including tumor size, histological grade, lymph node stage, and metastasis, and survival information were used to investigate the correlation between SERPINE1 or FOS expression and clinicopathological characteristics in 123 cancer patients (samples with incomplete information were excluded) (Supplementary Table 3). Here, SERPINE1 is linked to breast cancer.
