a Scheme showing full-length (FL) and the three indicated deletion mutants of the pGL-Cyclin D1 promoter according to JASPAR prediction. bf Rat GMCs were cultured with various treatments or transfected with different plasmids with or without sublytic C5b-9 stimulation for 3 h. The activity of the Cyclin D1 promoter and the binding elements of SOX9 were measured by luciferase reporter assay (bd) and ChIP-PCR (e, f). **p < 0.01 versus the MEM, Thy-1 Ab, Thy-1 Ab + HIS, or Thy-1 Ab + C6DS group or versus the pcDNA3.1, shCTR, or pGL3-basic + sublytic C5b-9 group; ΔΔp < 0.01 versus the shCTR + sublytic C5b-9, FL + sublytic C5b-9, -985 to +130 nt + sublytic C5b-9, or -582 to +130 nt + sublytic C5b-9 group. Data were represented as the means ± SD (n = 3 in each group in all experiments).
