Over-expression of miR-125a-3p hampers the organization of the nuclear actin rim. GV oocytes were microinjected with either scramble-miR (A) or miR-125a-3p mimic (B). Oocytes were incubated for 4 hours at 37 °C in the presence of 1 µM milrinone prior to fixation performed as described in ‘Experimental Procedures’. Actin filaments were stained with Tritc-Phalloidin (red) diluted in PBS containing 0.1% Triton X-100 and 3% BSA. DNA was stained with Hoecst (blue). (a) Tritc-Phalloidin; (b) Enlargement of the area marked in (a); (c) Bright field; (d) Merge of Tritc-Phalloidin and Hoecst. White arrow points at the actin rim of a scramble-microinjected oocyte. Yellow arrows point at gaps within the actin rim of a miR-125a-3p-microinjected oocyte.
