Transcriptome analysis of the liver in BALB/c substrains. (A) Sixteen BALB/cJ (four per sex per treatment) and 16 BALB/cByJ mice (four per sex per treatment) data were analyzed blocking the effects of sex and treatment. Sex-combined: a volcano plot shows the distribution of differentially expressed genes in liver homogenate of all mice (J-By expression). Zhx2 is denoted with an arrow. (B) Females: Using only females, data were analyzed blocking the effect of treatment. A volcano plot shows the distribution of differentially expressed PK genes in liver homogenate. For this figure, PK genes include Cyp, Ugt, Abc, and Slc genes. Note the robust downregulation of Ugtb37 in J females, denoted with an arrow. (C) Males: Using only males, data were analyzed blocking the effect of treatment. A volcano plot shows the distribution of differentially expressed PK genes in liver homogenate of male mice.
