Expression of AMPA type glutamate receptor in developing chick<br />

vestibulocochlear ganglia<br />

<br />

1<br />

Expression of AMPA type glutamate receptor GluR14 in the vestibular VG<br />

and cochlear ganglia CG in developing chick embryo was examined. VG and<br />

CG at the embryonic day 10 E10, E12, E14, E16, E18 and E20 were prepared<br />

for reverse transcriptasePCR RTPCR and immunohistochemistry IHC. In<br />

the RTPCR study, GluR1 mRNA was weakly expressed from E10 to E20 in both<br />

ganglia. Expression of GluR2 mRNA was intensive at E10 and E12 in VG and at<br />

E10E14 in CG, and then, it was gradually weakened from E14 in VG and from<br />

E16 in CG. Expression of GluR3 mRNA in both ganglia was weak at E12E18<br />

and it was extremely augmented at E20. GluR4 mRNA was moderately expressed<br />

at E10E14 in VG and at E10E16 in CG, and then, it was gradually increased<br />

from E16 in VG and from E18 in CG. In the IHC study, immunoreactivity of<br />

GluR2 was observed in the cytoplasm and process and that of GluR2/3 and<br />

GluR4 was in the cytoplasm of the VG and CG cells, while that of GluR1 was<br />

never detected. These results suggest that GluR2, GluR3 and GluR4 are the major<br />

subunits of AMPA receptor during the development of the chick embryo VG and<br />

CG cells. They would have different roles for the development.<br />
