ABSTRACT
· AIM:
To explore the dynamic expression and correlation among telomerase catalytic subunit (TERT), proliferating cell nuclear antigen ( PCNA) and antiapoptosis protein Bd-2 which relate to cell proliferation in epiretinal membrane of rat traumatic proliferative vitreoretinopathy(PVR).·METHODS:
S-P technique was applied for immunohistochemical staining of epiretinal membrane of traumatic PVR with TERT, PCNA and Bcl-2 antibody. HE staining was also carried out. The staining results were analyzed with image analysis system.·RESULTS:
The positive rate and average A of PCNA protein were upregulated at first and then down-regulated, with the peak value in 14d Group, which was significantly different from those in 7d Group and 28d Group.The positive rate and average A of TERT and Bcl-2 were also upregulated at first and then down-regulated, with the peak value in 14d Group and 21d Group, which were significantly different from those in 7d Group. There was significant correlation among PCNA, Bcl-2 and TERT protein expression (P≤0.01).· CONCLUSTON TERT and Bcl-2 take part in the regulation of proliferative cells in epiretinal membrane of traumatic proliferative PVR, with high correlation with the dynamic changes of cell proliferation.
