To evaluate VISTA gene expression and its association with clinicopathological features in breast cancer patients, we assessed VISTA transcripts in two different cohorts: breast cancer patients from the TCGA dataset (Table 1; Figure 1) and from a Moroccan cohort, including both tumor and adjacent uninvaded tissues, where real-time qRT-PCR was performed (Figure 2). The gene discussed is VSIR; the disease is breast cancer.
