Abstract
- PURPOSE
We analyzed the expression of vasoactive intestinal peptide (VIP), pituitary adenylate cyclase activating peptide (PACAP), VIP receptor 1 (VIPR1), VIP receptor 2 (VIPR 2) and PACAP receptor (PACAPR) genes in human neuroblastoma, neuroblastoma cell line, human stomach cancer, and human stomach cancer cell lines using RT-PCR and Sourthern hybridization. The results should permit identification of potential clinical applications for VIP and PACAP.
METHODS
We isolated RNA from 1 neuroblastoma cell line, 8 stomach cancer cell lines, 13 neuroblastoma, and 10 stomach cancer tumor specimens. And then we performed RT-PCR, Sourthern hybridization, and sequencing.
RESULTS
We detected the RNAs coding for VIP, VIPR1, VIPR2, PACAP, and PACAPR in 1, 11, 2, 12, and 13 out of 13 neuroblastoma tumor specimens, respectively. VIP and PACAPR RNA was expressed in SKNSH. VIPR1 RNA was expressed in 4 of 8 the stomach cancer cell lines and 6 of 10 stomach cancer tumor specimens.
CONCLUSION
VIP/PACAP RNA and VIP/PACAP receptors RNA were expressed in SKNSH and neuroblastoma tumor specimens. VIPR1 was expressed in stomach cancer cell lines and tumor specimens. The present results suggested that VIP/PACAP analogues could be a candidate as the growth inhibitor of neuroblastoma and stomach cancer.
