Fig. 5. Ftm is necessary for the establishment of a proper Gli3-190/Gli3-83
ratio in mice. (A) Immunoblots show the amounts of Gli3-190 and
Gli3-83 in E11.5 embryos. In wild-type and Ftm+/- embryos,
the majority of Gli3 protein was processed to form Gli3-83, and only small
amounts of Gli3-190 are detectable. In Ftm-/- embryos, the
amount of Gli-83 is equal to wild-type levels, but the amount of Gli3-190 is
increased. Note that there is an increase in total Gli3 protein in
Ftm-/- embryos. The lower part shows the loading control
with anti-tubulin antibody. (B) Graphical evaluation of the
Gli3-190/Gli3-83 ratio in wild-type, Ftm+/- and
Ftm-/- embryos. At least three embryos of each genotype
have been analysed. (C) RT-PCR analysis of RNA from E11.5 embryos. The
amount of Gli3 transcripts is increased in Ftm-/-
embryos in comparison with the wild type. The lower part shows the Hprt
normalization. (D) Comparison of relative Gli3 transcription
levels in wild-type and Ftm-/- embryos (n=3). In
Ftm-/- embryos, the number of Gli3 transcripts is
increased nearly twofold.
