(A) The photography of xenograft tumors from Balb/C null mouse injected with Hep3B cells transfected with pCMV6-AC-GFP, pCMV6-AC-GFP-JMJD2A subcutaneously at armpit (B) The xenograft tumors weight(gram) in the two groups. Data were means of value from nine Balb/c mice, mean ± SEM, n = 8, *P < 0.05; **P < 0.01. Data were means of value from nine Balb/c mice, mean ± SEM, n = 8, *P < 0.05; **P < 0.01. (C) A portion of each xenograft tumor was fixed in 4% formaldehyde and embedded in paraffin, and the micrometers of sections (4 μm) were made for hematoxylin-eosin (HE) staining (original magnification×100).
