  1. The cells were pre-treated for 24 h with different concentrations of PEF ranging from 0 to 40 μg/ml and positive control (10 μM or 1.7 μg/ml gallic acid). The media were replaced with a medium containing 5 μM of AFB1 and the cells were incubated for another 48 h
  2. The expression of each gene was normalised to the GAPDH and ß-actin expressions as housekeeping genes and then the result normalised to the expression of that gene in the negative control (PEF 0 μg/ml)
  3. S.E.M Standard error of the means
  4. Means (n = 3) with different superscripts (a,b,c,d) within a row are significantly different (p < 0.05)
