Figure 3. P2X4R genotype increases the early acquisition phase of 24-hr, two-bottle choice ethanol intake in male mice.

Figure 3

(a) P2X4R KO increases 10% ethanol (10E) intake compared to WT controls. (b) There was no significant effect of genotype on ethanol preference or (c) water intake, but there was (d) a trend for total fluid intake to be higher in P2X4R KO versus WT mice. The insets represent the average over the four consecutive days for WT (white bars) and P2X4R KO (black bars) mice. Values represent mean ± SEM for 12 WT and 10 KO mice. *p<0.05 compared to WT.
