Fig. 2From: Increased expression of neuregulin 1 in the urothelium of rat bladder with partial bladder outlet obstructionRepresentative RT-PCR expression (a) and comparison of relative expression of NRG-1 (b), ErbB2 (c) and M2 muscarinic receptor (d) mRNA expression in urothelium and detrusor muscle between control (black plot) and PBOO group (red plot). GAPDH was used as the loading control. Values of NRG-1, ErbB2 and M2 muscarinic receptor expression are normalized relative to GAPDH expression. The asterisk indicates a significant difference (Mann Whitney test p < 0.05)Back to article page
