Fig. 7From: Periostin drives extracellular matrix degradation, stemness, and chemoresistance by activating the MAPK/ERK signaling pathway in triple–negative breast cancer cellsHigh POSTN expression correlates with poor survival in patients with TNBC. Kaplan–Meier curves of survival in TNBC patients, as calculated using TCGA data. The median expression value was used to separate the POSTN–low and POSTN–high groups based on the Kaplan–Meier curve. a–b. POSTN expression was assessed for its association with OS, RFS, and DMFS in TNBC patients. The expression groups were divided into high (red) and low (black). The survival times are shown in months, and HR and confidence intervals (in brackets) are shown for the geneBack to article page
