TRIM44 promtoes aggregates deaggregation and clearance via autophagy. (a) Cells were treated with MG132 and immunostained with antibodies to ubiquitin (red) and LC3B-II (green). Arrows indicate ubiquitin-positive aggregates that colocalize with LC3B-positive autophagosomes. Scale bars: 10 μm.

Arrows indicate cells with remaining aggregates. The relative level of remaining aggregates is determinded by quantifying the percentage of cells with remaining aggregates after a 24-h chase period in normal culture media with DMSO (vehicle), or 3-MA (10 mM) and normalized to the percentage of cells with aggregates formed by the 16 h MG132 (0.5 µM) treatment in corresponding cells. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
