TCP1 and breast cancer: To this end, using TCGA data on survival probability in BC, we confirmed that TCP1 low expressing tumors had better prognosis, similar to the data obtained with SAMHD1 expression in our cohort, while CNN2, TYK2 and CRLF1 expression do not affect survival, in agreement with our data from RNA expression in tumor biopsies (Fig. 4D and Supplementary Fig. 3).
