Taking into account that TUBB showed differential KM plots in ERα-positive and ERα-negative breast cancer patients, it was crucial to explore the genes that significantly correlate positively and negatively with TUBB in ERα-positive and ERα-negative breast cancer patients to explore the pathways in which TUBB is involved in, as described in the summary of the experimental design (Figure 4). This evidence concerns the gene TUBB and breast carcinoma.
