Abstract:


Accumulated evidence have well established that protein sumoylation plays multiple roles in various cellular processes. In the vertebrate eye, we and others have demonstrated that sumoylation displays indispensable roles in regulating eye development. Various ocular cell lines including human embryonic cell line (FHL124), the SV40-large T-transformed human lens epithelial cell line (HLE), the SV40-large T-transformed mouse lens epithelial cell line (αTN4-1), the rabbit lens epithelial cell line (N/N1003A) and the human retina pigment epithelial cell line (ARPE-19) have been extensively used for studying various cellular functions and disease processes including sumoylation functions, and mechanisms for cataract and age-related macular degeneration (AMD). However, the sumoylation enzyme systems have not been well established. In this study, using QRT-PCR and western blot analysis, we have determined the expression patterns of seven de-sumoylation enzymes (SENP1, 2, 3, 5, 6, 7 and 8) in the above 5 major ocular cell lines, and the obtained results help to establish the basis for the future study of sumoylation functions and mechanisms in vertebrate eye.
