In this study, we confirmed the diverse molecular activity of Antp-TPR in the presence of R11-Hsp70, compared with 17-AAG, toward cancer cells and we found that the combination of Antp-TPR with R11-Hsp70 induced neither up-regulation of Hsp90, Hsp70, Hsp27, or Hop, nor an increase in GSH concentration in breast cancer cells (Figure 3, Figure 4, and Figure 5A). Here, HOXA7 is linked to breast carcinoma.
