Differentially expressed genes in MUC1 transfected cells. A. Expressional clustering of genes expressed at least two-fold differently in (a) MUC1 transfected 3Y1 cells compared with (b) cells transfected with empty vector. B. A functional network involving many of these upregulated (pink) and downregulated (green) genes. Functions include cell cycle, cellular assembly and organization, DNA replication, recombination and repair.
