FIGURE 1.
Effects of SHK on cell proliferation and cell cycle arrest. (A) Chemical structure of SHK (MW = 288.3). (B) Cell viabilities of A549 and H1299 cells were measured by MTT assay after treatment with SHK (0–6 μM) for 24, 48, and 72 h. (C) EdU incorporation was evaluated after SHK treatments for 72 h, and mean EdU fluorescences in SHK treatments were relative to that in control treatment, which was arbitrarily set as 100. (D) Percentages of cell cycle arrest were analyzed by flow cytometry after SHK treatments. (E) Expression of Cyclin D1 in A549 and H1299 cells after SHK treatments. Data represent mean ± SD (n = 3). ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001 vs. Ctrl (control).
