  1. Genes that were differentially expressed following ubiquitous overexpression of otd or human Otx2, grouped according to Gene Ontology (GO) functional classes. n, Number of transcripts detected that belong to an individual class. N, Number of transcripts represented on the chip for each functional class; the value of N for each functional class is given in parentheses following the class name. n/N × 100, Percentage of transcripts that were differentially regulated for each functional class relative to the total number of transcripts in that class represented on the chip. M, Total number of differentially expressed transcripts (of all classes) following overexpression of otd or human Otx2 (p ≤ 0.001); for otd and Otx2, M is 287 and 682 respectively. n/M × 100, Percentage of transcripts that were differentially regulated in each functional class relative to the the total number of differentially regulated transcripts for otd and Otx2.
