The intersected ceRNAs in tissue exosomes derived from luminal B BC and TNBC patients [lncRNA OAZ1/miRNA hsa-miR-7851-3p/multiple mRNAs (ALG12 and HOXA5), multiple lncRNAs (COTL1, HMG20B, SORBS3)/miRNA hsa-miR-10396b-5p/mRNA PAK6] are provided in Figure 7, and the relevant ceRNAs are listed in Table 3. Here, HOXA5 is linked to breast cancer.
