Figure Lengend Snippet: PTC209-induced DNA damage activates NF-κB signaling pathway in CSCs (A) Immunostaining and quantification of pH2A.X (red) in HNSCC cells treated with PTC209. DAPI stained the nuclei blue. Scale bar, 20 μm. (B) Percentage of pH2A.X in HNSCC cells from different treatment groups as indicated. Data are shown as the mean ± SD. ∗∗ p < 0.01 using an unpaired Student’s t test. (C) Western blot analysis of pH2A.X in HN6 and SCC15 cells treated with PTC209. (D and E) Histogram of the top 10 most-enriched GO (D) and KEGG (E) terms for upregulated genes (FC > 2) in ALDH + HN6 cells treated with PTC209. The red rectangles indicate genes related to NF-κB signaling. (F) Western blot analysis of pIKK-α/β, IKK-α, IKK-β, pIκB-α, IκB-α, p-P65, and P65 in HNSCC cells with PTC209 treatment. (G) Representative images of p65 immunostaining (green) in HN6 and SCC15 cells treated with PTC209. DAPI stained the nuclei (blue). Scale bar, 20 μm. See also .
Article Snippet: The human HNSCC cell line SCC15 was from the American Type Culture Collection (ATCC, Manassas, VA, USA), and HN6 was from the Central Laboratory of Peking University School and the Hospital of Stomatology (Beijing, China).
