We found that the gpa-12 mutation did not enhance the axon regeneration defect of ser-7 mutants (Fig. 3a and Supplementary Table 2), suggesting that SER-7 and GPA-12 function in the same pathway.
The ser-1;ser-7 double mutant did not show stronger Fluoxetine resistance than the ser-7 single mutant, as measured after 40 min and 24 hr of exposure to fluoxetine.
