On the other hand, the additional 5 genes showed a high R-index = 0.9 or beyond (Figure 5e), and COL11A1 and TAGLN expressions as shown in red letters were uniquely associated with SPARC expression in cancer stroma of the TNBC tumors (both R-index below 0.6 in total BC). The gene discussed is COL11A1; the disease is breast cancer.
