The cytotoxic effect of monosodium glutamate (MSG) on the cell viability of the oestrogen-positive MCF-7 (A) and the oestrogen-negative MDA-MB-231 (B) cells at 24, 48 and 72 h. The data were presented as mean ± SD, n = 3. ∗p ≤ 0.05; and ∗∗∗p ≤ 0.001 indicate a significant difference between 24 h and 48 h, while #p ≤ 0.05; and ###p ≤ 0.001 indicate a significant difference between 48 h and 72 h.
