Figure 6: Western blots showing the proliferative effect of glyphosate (0.1 mM) and TPA (10 nM) on the expression levels of (a) Ca2+ binding and oxidative stress and (b) apoptosis-related proteins in HaCaT cells for 24, 42, and 72 h. The bands shown here are from a representative experiment repeated three times with similar results. Equal loading was confirmed by stripping the immunoblot and reprobing it for β-actin. Quantitative fold change was calculated in respect to control on the basis of pixel density measured by UNSCAN-IT software.
