There was statistically significantly higher expression level of BIRC2 (p < 0.0001), BIRC3 (p < 0.0001), and BIRC5 genes (p < 0.0001) in TNBC patients compared to non-TNBC patients, and statistically significantly lower BIRC1 (p = 0.0011) and BIRC4 gene expression levels (p < 0.0001) in patients with triple negative breast cancer compared to other BC patients (Figure S1). The gene discussed is XIAP; the disease is breast cancer.
