Fig 4. P2x subunit expression in response to the loss of P2x6 function in the kidney.

a-f) The mRNA expression levels of P2x1 (a), P2x2 (b), P2x3 (c), P2x4 (d), P2x5 (e), P2x7 (f), in kidney of P2x6^+/+ (Black bars), P2x6^+/- (Striped bars), P2x6^-/- (white bars) mice were measured by quantitative RT-qPCR and normalized for Gapdh expression. Data (n = 10) represent mean ± SEM and are expressed as the fold difference when compared to the expression in P2x6^+/+ mice.
