Inversely, in C10, the expression of immune markers, such as CD45, was positively correlated with LTA expression in all four breast cancer subtypes except LB, and the expression of LTA was negatively correlated with the expression of breast cancer markers associated with abnormal cell growth, namely HER2 and Ki67 (upper half of Fig. 5k, Supplementary Fig. 7e and Supplementary Table 9). Here, PTPRC is linked to breast carcinoma.
