Fig. 8. Expression of esc in Df(2R)achi1
mutants. (A) RT-PCR analysis on RNA samples from wild-type and
Df(2R)achi1 mutant testes reveal that
esc is amongst the genes showing enhanced transcript abundance in
Df(2R)achi1 mutants, other enhanced transcripts
include haywire and Taf24. (B) Anti-Esc immunolabelling on
wild-type testes. Esc accumulates in nuclear speckles during primary
spermatocyte differentiation. (C) Anti-Esc immunolabelling on
Df(2R)achi1 testis. Esc is clearly expressed and
demonstrates the expansion of the early primary spermatocyte population.
Nuclear speckles do not form.
