Article Title: Zinc controls PML nuclear body formation through regulation of a paralog specific auto-inhibition in SUMO1
doi: 10.1093/nar/gkac620
Figure Lengend Snippet: Increasing cellular zinc levels in senescent cells enhances PML-NB formation. Normal human fibroblasts IMR90 cells expressing a control vector or the activated RAS oncogene, to induce senescence, were treated for 24 h with either control vehicle, 5 μM pyrithione (PT) or 1 μM TPEN prior to fixation and quantitative analysis for the overall number of PML-NBs per cell ( A ) and the number of PML-NBs greater than 1 μm in size ( B ). For each condition, 50 cells from two independent experiments were counted and statistics were performed using the PRISM9 software.
Article Snippet: Normal human diploid fibroblasts IMR90 cells were purchased from Coriell Institute for Medical Research (Camden, NJ) and Phoenix Ampho packaging cells were a gift from Dr Scott W Lowe (Sloan Kettering Memorial).
