1.3.3 Microarray Analysis of MOT1 Mouse
MOT1 is a model that expresses SV-40 T antigen under the opsin promoter (AlUbaidi et al. 1992). The expression of the viral oncogene forces the postmitotic photoreceptors to re-enter the cell cycle and then undergo apoptosis. At P10 there is no photoreceptor loss. However at P15, there is a loss of 50% rod photoreceptors and only cone photoreceptors survive by P25 (Al-Ubaidi et al. 1992). In this model, we observed gene modulations as early as P10 whereby, 36 genes were differentially expressed (Table 1.3). Out of these, 20 genes were down-regulated and 16 genes were up-regulated. Down regulated genes belonged to the categories of phototransduction (65%), transport protein (16%) and unknown genes (20%) while Up-regulated genes fell into the categories of DNA binding proteins (25%), transcription factors (13%), protein binding (25%), cell cycle (13%), ubiquitin cycle (13%) and unknown genes (13%).
