Expression of pituitary adenylate cyclase activating polypeptide receptors in the early mouse embryo as assessed by reverse transcription polymerase chain reaction and in situ hybridisation

We have examined the expression of mRNA for the pituitary adenylate cyclase activating polypeptide (PACAP) receptor in the mouse from day 9.5 of embryonic development onwards by reverse transcription polymerase chain reaction (RT-PCR) and by in situ hybridisation. PACAP receptor mRNAs were detected...

Zusammenfassung:We have examined the expression of mRNA for the pituitary adenylate cyclase activating polypeptide (PACAP) receptor in the mouse from day 9.5 of embryonic development onwards by reverse transcription polymerase chain reaction (RT-PCR) and by in situ hybridisation. PACAP receptor mRNAs were detected by PCR in the earliest developmental stage examined and thereafter the levels of mRNA for all receptors increased during development. Wholemount in situ hybridisation first showed the expression of the PACAP receptor in the neural tube of 9.5 day old embryos, in later embryos heaviest expression of the PACAP receptor was found in the developing rhombencephalon (day 10.5 and 11.5).These results are consistent with a role for PACAP or a related peptide in the early development of the central nervous system.
