Fig. 1. Activation and nuclear accumulation of Dd-STATc by osmotic stress. Ax2
cells were allowed to develop for 4 hours in shaken suspension, were harvested
and then divided into two. One portion was incubated in KK2 containing 200 mM
sorbitol and the other portion was incubated in KK2 containing 100 nM DIF. At
the indicated times, one aliquot was harvested and the specific tyrosine
phosphorylation level of Dd-STATc was determined by western transfer (A). At
the same time, a separate aliquot was analysed immunohistochemically to
determine the proportion of cells showing nuclear enrichment of Dd-STATc (B).
The results are shown as the mean±s.d. but the error bars at 5, 10 and
15 minutes for the sorbitol treated sample are so small as to be obscured by
the filled boxes.
