Fig 2. p21 nuclear/cytoplasmic transport of p21 is regulated by SENP2 and UBC9.

Fig 2

Left: Graph shows the percentage of HCT116 cells with HA-p21 present in the cytoplasm determined by immunofluorescence analysis using anti-HA (Roche). Representative images are shown in S3A Fig. 48 hours after transfection with non-targeting (siNT), UBC9 (siUBC9), or SENP2 (siSENP2) siRNAs, cells were transfected with HA-p21 plasmid and 24 hours after treated (Adr) or not (Ctrl) with Adr for 12 hours. Data are the average of 3 different experiments and in each one at least 200 HA-p21 transfected cells were counted per condition. Rigth: Western Blotting to detect UBC9 or SENP2 levels in non-depleted or depleted-HCT116 cells; (-): correspond to cells after 48h of transfection with siRNA and priori to HA-p21 transfection.
