CXCL3 and breast angiosarcoma: RT-PCR analysis also showed that the mRNA levels of C–X–C motif chemokine ligand 3 (CXCL3), monocyte chemoattractant protein-1 (MCP-1, CCL2) and its receptor chemokine (C-C motif) receptor 2 (CCR2) were higher in livers of BA patients than in controls, but not significant (Fig. S5).
