Fig. 5: L1 ORF1p influences PIN1 cellular localisation.

a Immunocytochemical (ICC) images of Hep3B cells transfected with plasmid expressing L1 ORF1p wild-type (WT) or S18AS27A mutant form and costained for PIN1 and L1 ORF1p. Anti-PIN1 antibody was directly conjugated with AF-594 and L1 ORF1p was visualised using anti-L1 ORF1p with an anti-mouse-AF488 secondary antibody. DAPI was used to counterstain nuclei. Scale bar = 20.1 µm. b ICC images showing Pin1 staining in Huh7 non-targeted shRNA control cells (NT) and L1 knockdown cells (L1KD). Cells were stained with mouse-anti-PIN1 antibody followed by anti-mouse-AF488 secondary antibody. DAPI was used to counterstain the nuclei. c Representative PIN1 IHC images (scale bar = 200 µm) showing PIN1 cytoplasmic and nuclear status on top. The table below represents number of cases belonging to indicated categories. *P < 0.05, chi-square test.
