Figure 1.
Seasonal variation in metabolic profile and anticancer bioactivity of J. rubens. Aerial (A) and closeup (B) view of J. rubens showing the characteristic dense clusters of branchy segmented cylindered thallus. (C) The cytotoxic activity of J. rubens methanolic extracts from each season toward A549 cells after 48 h incubation was assessed via microscopy imaging of Hoechst and PI staining and statistically analyzed by Wilcoxon test. Each dot represents an average of 3 independent experiments and presented as mean ± SE (*P < 0.05, ***P < 0.001). (D) J. rubens seasonal metabolic variation displayed by an NMDS plot, each ellipse represents a hierarchical cluster analysis.
