Figure 4. Apigenin inhibits HSF migration by suppressing FAK phosphorylation. (A) Transwell assays (without Matrigel) with HSFs overexpressing vector or FAK and treated with 20 μM apigenin,. **P < 0.05 vs. NaCl group. ## P < 0.05 vs. NaCl with FAK overexpression group. (B) Transwell assays (without Matrigel) with HSFs transfected with si-FAK or si-NC (negative control) and treated with 20 μM apigenin. **P < 0.05 vs. NaCl group. (C, D) HSFs overexpressing vector or FAK were treated with 20 μM apigenin, after which western blot and real-time PCR assays were performed to detect levels of MMP2 expression. **P < 0.05 vs. NaCl group. ## P < 0.05 vs. NaCl with FAK overexpression group. (E, F) HSFs transfected with si-FAK or si-NC (negative control) were treated with 20 μM apigenin, after which western blot and real-time PCR assays were performed to detect levels of MMP2expression. **P < 0.05 vs. NaCl group.
