"We analyzed the expression of
des-2:GFP in the ALA neuron of
ceh-14 and ceh- 17 null mutant animals and found that at the L1 stage, reporter expression is dependent on CEH-14 but not on CEH-17 (Fig 4B), consistent with our observed genetic results with
deg-3(gf). At the L4 stage, however,
deg-3 expression is dependent on both factors (Fig 4B,C), revealing different temporal requirements for CEH-17 and CEH-14 in
deg-3 expression."
