An association between the MSI2a and TP53INP1 mRNA levels was also observed in our cohorts of breast cancer tissues (Fig. S3b), the CCLE breast cancer cell lines (Fig. S3c), TCGA breast cancer dataset (Fig. S3d), and the GESA76250 TNBC samples (Fig. S3e). Here, TP53INP1 is linked to breast carcinoma.
