Abstract: Cancer-associated fibroblasts (CAFs) promote tumorigenesis, growth, invasion and metastasis of cancer, whereas normal fibroblasts (NFs) are thought to suppresstumor progression. Little is known about miRNAs expression differences betweenCAFs and NFs or the patient-to-patient variability in miRNAs expression in breastcancer. We established primary cultures of CAFs and paired NFs from six resected breast tumor tissues that had not previously received radiotherapy orchemotherapy treatment and analyzed with miRNAs microarrays. The array data were analyzed using paired SAM t-test and filtered according to α and q values.Pathway analysis was conducted using DAVID v6.7. We identified 11 dysregulatedmiRNAs in CAFs: three were up-regulated (miR-221-5p, miR-31-3p, miR-221-3p),while eight were down-regulated (miR-205, miR-200b, miR-200c, miR-141, miR-101,miR-342-3p, let-7g, miR-26b). Their target genes are known to affect celldifferentiation, adhesion, migration, proliferation, secretion and cell-cellinteraction. By our knowledge it is firstly identify the expression profiles ofmiRNAs between CAFs and NFs and revealed their regulation on the associatedsignaling pathways.
