CCL2 and cancer: It is of interest that many of the genes associated with the differentially expressed mRNAs in the xenografts were found to be identical to predicted target genes of differentially expressed miRNAs, and that they were related to cancer and metastasis, e.g., FSCN1[42], CCL2[46], ADAMTS1[45], FGFR1[44], CTGF[48] and SERPINB5[49].
