Expression of pituitary adenylate cyclase-activating polypeptide 1 and 2 receptor mRNA in gallbladder tissue of patients with gallstone or gallbladder polyps.
OBJECTIVE
To detect the expression of pituitary adenylate cyclase-activating polypeptide receptor 1 (VPCAP1-R)and VPCAP2-R mRNA in gallbladder tissues of patients with gallstone or gallbladder polyps.


METHODS
The expression of VPCAP1-R and VPCAP2-R mRNA in gallbladder tissues was detected in 25 patients with gallstone,8 patients with gallbladder polyps and 7 donors of liver transplantation by reverse transcription polymerase chain reaction (RT-PCR).


RESULTS
The VPCAP2-R mRNA expression level in the control group (1.09+/-0.58) was lower than that in the gallbladder polyp group (1.64+/-0.56) and the gallstone group (1.55+/-0.45) (P<0.05) while the VPCAP1-R mRNA expression level in the control group (1.15+/-0.23) was not apparently different from that in the gallbladder polyp group (1.28+/-0.56) and the gallstone group (1.27+/-0.38).


CONCLUSIONS
The abnormal expression of VPCAP2-R mRNA in gallbladder tissue may play a role in the formation of gallbladder stone and gallbladder polyps.
