(C) LMB treatment restricted the p27kip1 inside the nucleus of siSENP1 RBE cells. (D) LMB-treated siSENP1 RBE cells showed significantly decreased levels of nuclear SUMOylated p27kip1, but no significant changes in cytoplasmic SUMOylated p27kip1 expression levels.

    Figure Lengend Snippet: SUMOylation levels of nuclear and cytoplasmic p27kip1 in LMB-treated cells. (A) LMB treatment restricted the p27kip1 inside the nucleus of SENP1-oe RBE cells. (B) LMB-treated RBE cells showed significantly increased levels of nuclear SUMOylated p27kip1, but no significant changes in cytoplasmic SUMOylated p27kip1 expression levels. (C) LMB treatment restricted the p27kip1 inside the nucleus of siSENP1 RBE cells.

    Article Snippet: For nuclear export inhibition assays, cells were treated with 20 nM LMB (Beyotime Institute of Biotechnology), to block the p27kip1 transporter CRM1, at 37°C for 12 h in 10% FBS in medium, which was then used for nuclear and cytoplasmic protein separation, WB and SUMOylation tests.
