Figure 9.
DNA synthesis and fragmentation in blood cells (a–c,g–i,m–o) and CLS-354 tumor cells (d–f,j–l,p–r) after 24 h exposure to different concentrations [3:3; 3:2; 3:1] of U. barbata extract in canola oil (UBO); (a–f) and canola oil (CNO) (g–l) compared to C1, C2P, and C3UA controls (m–r). C1—1% DMSO (negative control), C2P—5% Poloxamer 407 (positive control), C3UA—usnic acid (positive control), AP—cell apoptosis (DNA fragmentation, subG0/G1), S—DNA synthesis. [3:3; 3:2; 3:1]—culture medium/sample ratio (v/v).
