Figure 3. Chromofungin attenuated oligomeric Aβ42-induced cellular senescence of M17 neuronal cells. Cells were incubated with oligomeric Aβ42 (5 μM) with or without Chromofungin (0.5, 1 mM). Cellular senescence was examined using SA-β-gal staining at day 14. Scale bar, 50 μm (n = 6, **P < 0.01 vs. vehicle group; †, ††P < 0.05, 0.01 vs. Aβ42 group).
