The protective effects of K. parviflora against neurogenesis-inhibiting Aβ₄₂ peptides in monoculture of differentiated NE-4C cells. (A) beta-III tubulin mRNA levels and (B) MAP-2 mRNA levels. The ^### shows a significantly different between control and cells exposed to Aβ₄₂ peptides without KP extract at p < 0.001 using one-way ANOVA followed by Tukey’s test. The * shows a significantly different between cells exposed to Aβ₄₂ peptides without KP extract compared to cells exposed to Aβ₄₂ peptides and various concentrations of KP extract (0.5–8 µg/mL) using one-way ANOVA followed by Tukey’s test. *, p < 0.05, **, p < 0.01, ***, p < 0.001.
