Fig 1: Effect of oxamate LDHA expression and TUNEL staining in cartilage tissues after ACLT administration. (A) Immunohistochemical analysis of LDHA and (C) TUNEL staining in joint sections from the sham, ACLT, and ACLT + oxamate (0.25 or 2.5 mg/kg) groups. The quantitative analysis of the ratio of (B) LDHA-positive and (D) TUNEL-positive cells in joint sections is presented. Data are expressed as means ± SEM for each group. The scale bar represents 100 µm. (* p < 0.05, compared with the sham group; # p < 0.05, compared with the ACLT group). LDHA: lactate dehydrogenase A; TUNEL: terminal deoxynucleotidyl transferase dUTP nick-end labeling.
