Article Title: PRMT5–mediated symmetric dimethylation of SHBs at Arg169 stabilizes SHBs and promotes angiogenesis and tumor growth
doi: 10.1016/j.tvr.2026.200340
Figure Lengend Snippet: Arg169 symmetric dimethylation is required for SHBs–driven angiogenesis and tumor growth. (A) WB analysis of SHBs and BIP expression in stably transduced Huh7 and HepG2 cells (Vector, SHBs, and SHBs/R169K). (B) ELISA measurement of VEGFA levels in the supernatants of Huh7/HepG2–Vector, Huh7/HepG2–SHBs, or Huh7/HepG2–SHBs/R169K cells. (C) Endothelial tube formation assay. EA.hy926 cells were cultured with conditioned media (CM) from Huh7 or HepG2 stable lines (Vector, SHBs, SHBs/R169K). Representative images and quantification of mesh numbers are shown. (D) Transwell migration assay. EA.hy926 cells were assessed for migration in response to CM from the indicated stable lines. Representative images and quantification of migrated cell numbers per field are shown. (E) Representative images of excised subcutaneous xenograft tumors derived from Huh7–Vector, Huh7–SHBs, or Huh7–SHBs/R169K cells. (F) Tumor growth curves (tumor volume over time) for the indicated xenograft groups. (G) Tumor weights at endpoint. (H) Representative immunohistochemical staining of xenograft tumors for CD31 and SHBs, with quantification of microvessel density (MVD) based on CD31 staining. Data are presented as mean ± SD; ∗ P < 0.05 as indicated.
Article Snippet: The supernatants were collected from cells, and VEGFA was quantified by using the Human VEGF/VEGFA ELISA Kit (Boster, # EK0539).
