Figure 2: (a) Cells were treated with CB-PIC (0 or 40  g/mL) under normoxia and hypoxia both for 6 and 8 hr. Cell cycle distribution was analyzed by flow cytometry. (b) Bar graphs represent the percentage of the sub-G1 of apoptotic DNA fraction. Data are presented as means SD. compared with normoxia CB-PIC-(40  g/mL) treated groups.
