Comparison of differentially expressed genes following single gene over-expression in our cell bank mouse ES cell lines versus transchromosomic Tc1 mouse ES cell lines. The colors indicate the overexpression experiment in which the expression value was found to be significant; for genes whose expression was significant in more than one overexpression experiment, only the one with the largest absolute value was considered. A total of 168 points are in the graph, of which 125 fall in same-sign quadrants. The regression line was forced to pass through the origin in order to highlight the general trend with respect to zero.
