Structural identification of the PDRG1-EZH2 binding interfaces and the functional requirement of their interaction in HCC progression. (A) Co-IP using EZH2 and PDRG1 truncation mutants demonstrates that the N-terminal region of EZH2 (amino acids 1-340) and the N-terminal segment of PDRG1 (amino acids 36-70) mediate their interaction in SNU449 cells. (B) Structural modeling predicts a stable interaction interface between the N-terminal helix of PDRG1 and the N-terminal region of EZH2. (C-F) CCK-8, wound-healing, Transwell, and colony formation assays show that overexpression of the PDRG1 Δ36-70 promotes cell proliferation, migration, invasion, and clonogenicity in SNU449 cells. All experiments were performed with three independent biological replicates (n = 3). (G) Western blot analysis indicates that the overexpression of PDRG1 Δ36-70 suppresses p21 and SASP factors and activates p-CDK2 and p-RB in SNU449 cells.

Mice were mock-treated (healthy group, white bars with circles) or asymptomatically infected with HSV-1 in the brain (HSV-1 group, orange bars with triangles). EAE was induced four weeks after mock treatment (EAE group, blue bars with diamonds) or infection (HSV-1-EAE group, purple bars with squares). Brain homogenates were recovered fourteen days after EAE induction, 45–50 days after HSV-1 infection, or mock treatment alone.
