| Funtion Description |
By co-immunoprecipitation analysis, we show that farnesylated Progerin interacts with human PML2, which accounts for the formation of thread-like PML NBs. Specifically, human PML2 but not PML1 overexpression in HGPS cells promotes PML thread development and accelerates senescence. Further immunofluorescence microscopy, immuno-TRAP, and deep sequencing data suggest that these irregular PML NBs might promote senescence by perturbing NB-associated DNA repair and gene expression in HGPS cells
