Figure Lengend Snippet: Misfolded Httex1 causes nuclear depletion and sequestration of endogenous TDP43 to Httex1 aggregates. Representative images of HEK293T cells 24 h after transfection with Httex1(Q72) expression construct. Httex1 is visualized by PHP1 antibody ( magenta ), endogenous TDP43 is visualized by TDP43 antibody ( green ) and cell nuclei are visualized by DAPI counterstain ( blue ). The arrows highlight cells with cytoplasmic Httex1(Q72) and normal nuclear TDP43 labeling. Arrowheads point to cells with aggregates where Httex1(Q72) and TDP43 colocalize and TDP43 signal appears depleted from the nucleus. Scale bar is 20 μm for all the panels.
Article Snippet: Cells were transfected with 500 ng of Httex1(Q72) plasmid DNA (Genscript) using Lipofectamine LTX with Plus Reagent transfection kit (ThermoFisher), according to the manufacturer’s protocol.
