Figure Lengend Snippet: The cultured cells grew into monolayer and showed a polygonal “cobblestone-like” appearance (a). The cultured cells showed a positive reaction to cytokeratins by immunofluorescence, and the signal was detected in cytoplasm (b).

Article Snippet: The cells were then incubated with primary mouse antibody against cytokeratins (1 : 150 dilution; Boster, China) at 37°C for 90 min. After incubation, the cells were washed in PBS and incubated with TRITC-labeled goat-anti-mouse secondary antibody (1 : 50 dilution; Boster, China) at 37°C for 60 min. Coverslips were finally mounted for observation.

Article Title: TIP60 governs the auto-ubiquitination of UHRF1 through USP7 dissociation from the UHRF1/USP7 complex

doi: 10.3892/ijo.2021.5269

Figure Lengend Snippet: TIP60 interferes with UHRF1-USP7 association and their expression levels. HeLa cells were transfected with either TIP60-eGFP WT or TIP60ΔMYST-eGFP mutant. Western blot and immunoprecipitated samples were resolved by SDS-PAGE and immunoblotted with anti-UHRF1, anti-USP7 and anti-DNMT1 antibodies. (A) Effect of TIP60 on UHRF1, USP7 and DNMT1 levels with or without MG-132 treatment, respectively. (B and C) Quantification of the effect of TIP60 on UHRF1, USP7 and DNMT1 levels with or without MG-132 treatment, respectively. Values are the mean ± SEM from at least three independent experiments which were analyzed statistically by one-way ANOVA with Tukey's post hoc test ( * P<0.05; *** P<0.001 vs. control group). (D) Anti-UHRF1 antibody was used to co-immunoprecipitate UHRF1 and its partner USP7. (E) In a reciprocal experiment, anti-USP7 antibody was used to co-immunoprecipitate USP7 and UHRF1. Inputs and IP gels were processed in parallel under similar conditions. UHRF1, ubiquitin-like, containing PHD and RING finger domains 1; TIP60, Tat interactive protein, 60 kDa; USP7, ubiquitin-specific-processing protease 7; DNMT1, DNA methyltransferase 1.
