Figures & data

Figure 1. The expression of TRIM22 was promoted in cataract tissues. (a, b) The expression of TRIM22 in cataract tissues was detected with the RT-PCR and western blotting. (c) Immunohistochemical staining was performed for the detection of the expression of TRIM22 in cataract tissues. (d, e) The expression of TRIM22 in lens epithelial cells was detected with the RT-PCR and western blotting. ** p < 0.01 (Control vs H2O2)
