Both
mir-34(
gk437) and
mir-83(
n4638) single mutant populations display migration defects at a low frequency, 10.67 +/- 1.15% and 8 +/- 0% respectively. The phenotype's penetrance is significantly enhanced to 26 +/-7.21% in the
mir-83(
n4638);
mir-34(
gk437) double mutant (p < .05, unpaired t-test), suggesting that the two miRNAs contribute partially redundant functions in the context of DTC migration.
