As RAGE has been shown to bind to S100A7 in various immune shown in Fig. 2C, PyMT cells expressed high RAGE expression. cells (14). When analyzing the RAGE and S100A7 expression in Next, mice were injected with PyMT cells and observed for tumor breast cancer (TCGA), we discovered that RAGE and S100A7 are growth for 35 days (Fig. 2D).

To identify the an irrelevant gene ERK (mapk1) showed no correlation with RAGE signaling molecules that are associated with breast cancer tumor or S100A7 (Fig. 3A). This co-currency of gene upregulation growth, we examined the expression of ERK, cyclin D1, and implies a functional link between RAGE and S100A7 in breast MMP2 in PyMT-derived tumor tissues obtained from RAGE / cancer. Furthermore, we observed enhanced expression of RAGE mice. We observed reduced phospho-ERK, MMP2, cyclin D1, in S100A7-overexpressing MDA-MB-231 cells by Western blot, CD31, and Ki67 expression in RAGE / mice compared with FACS, and immunofluorescent analyses (Fig. 3B–D).

Proinflammatory RAGE ligands, naRAGE S100A7/S100a7a15 such as S100B, S100A4, and S100A8/A9, have been shown to enhance RAGE expression, and continuous activation of RAGE maintains an inflammatory milieu at the tumor microenviron-

We also showed that blocking sRAGE RAGE or inhibiting S100A7/mS100a7a15 binding to RAGE by Intracellular soluble RAGE (sRAGE) inhibits breast cancer cell migration and Decoy ERK activation. The sRAGE acts as a decoy that prevents ligands Cytokines from interacting with the cell surface receptor. The application of sRAGE in vitro and in vivo resulted in an effective blockade of RAGE, in accordance with this decoy mechanism, in a range of animal models (11). It is well documented that S100A8/A9-RAGE axis plays a significant role in breast and colon cancer growth TAMs Tumor and metastasis by modulating its downstream targets such as ERK1/2 (P44/p42), MAPK, and NF-kB signaling pathways MMPs (7, 42, 45).

We have shown previously that mS100a7a15 overexpression in mammary glands enhanced mammary tumor growth metastasis through Metastasis macrophage recruitment (18). To further analyze molecular mechanism of these effects, we blocked RAGE activation in Figure 7. MMTV-mS100a7a15–inducible model by naRAGE or sRAGE.
