Fig. 6. (A-D) Co-lipofection of Xath5 with Xbh1 and
Xbh1Vp16 constructs. Xath5 was lipofected either with
GFP+pCS2 (A), or with GFP+Xbh1 (B) or
GFP+Xbh1Vp16 (C), and their effect analyzed on cell-type
frequencies in transfected clones (D). Counted cells were: n=2625
cells from six retinae for GFP; n=2908 cells from six
retinae for Xbh1; n=3707 cells from 19 retinae for
Xbh1Vp16; n=885 from eight retina for Xath5;
n=1368 cells from eight retinae for Xath5+Xbh1;
n=1081 from five retinae for Xath5+Xbh1Vp16. Error bars
represent s.e.m.; significant differences have been calculated by one-way
analysis of variance with the Tukey-Kramer Multiple Comparisons Test as a post
test (***P<0.001). Symbols are as in
Fig. 3. (E) RT-PCR analysis of
animal caps injected with different combinations of mRNA, as indicated. Caps
injected with either Xath5 (500 pg) or Xbh1 (500 pg) show
activation of Xbrn3d. By contrast, animal caps injected with
Xath5 (500 pg)+Xbh1Vp16 (500 pg), or with Xbh1Vp16
(500 pg) alone show no activation of Xbrn3d expression.
