Synergistic anticancer properties of docosahexaenoic acid and 5-fluorouracil through interference with energy metabolism and cell cycle arrest in human gastric cancer cell line AGS cells

Figure 2 Morphological changes in AGS cells treated with docosahexaenoic acid and 5-fluorouracil alone or in combination. AGS cells were treated with medium only (control, A), docosahexaenoic acid (DHA) alone (30.00 μg/mL, B), 5-fluorouracil (5-FU) alone (12.50 μg/mL, C), or DHA plus 5-FU (30.00 μg/mL + 12.50 μg/mL, D) for 48 h. The cells were observed under an inverted-phase microscope. The photographs were taken at magnification × 200.
