We noted significant declines in the level of several transcripts associated with metastasis (Cd36 [21], Egr3 [22, 23, 24], and Maf [25]) and tumorigenesis (Ccr2 [26] and Ccr6 [27]) in many solid tumors including breast cancer (Fig. 3 and Table 1). The gene discussed is MAF; the disease is breast carcinoma.
