Fig. 1From: MiR-613 inhibits proliferation and invasion and induces apoptosis of rheumatoid arthritis synovial fibroblasts by direct down-regulation of DKK1Level of DKK1 in RA tissues and SFs. (a) Relative DKK1 expression levels in RA tissues and their corresponding adjacent normal tissues. (b) Relative DKK1 level analyzed by RT-PCR in RASFs and their corresponding adjacent normal SFs normalized with U6 snRNA. All data are presented as mean ± SEM, n = 6. **P < 0.01 vs. normal tissues or SFsBack to article page
