Fig. 20. 5-Aza inhibits the proliferation-associated protein of FLSs. (A) After AIA FLSs were incubated with 5-Aza, the protein levels of c-Myc, cyclinD1, and PCNA were analyzed by western blot in AIA. (B) AIA FLSs were treated with 5-Aza, and the mRNA levels of c-Myc and cyclinD1 were analyzed by q-PCR. All values are expressed as the mean ± SD. ^## P<0.01 vs. normal group. ^*P<0.05, ^**P<0.01 vs. AIA group.
