The mRNA level of UNC-31 was up-regulated by about 20% in
mir-71(lf). The nuclear-localized GFP expression under the control of the 3'UTR of
unc-31was strongly repressed in the control worms, but prominently derepressed in
mir-71(lf) mutant worms. These results suggest that miR-71 regulates the expression of
unc-31 through their 3'UTRs.
