Figure 6From: Semi-purified extracts of Commelina benghalensis (Commelinaceae) induce apoptosis and cell cycle arrest in Jurkat-T cells Effects of the F1 fraction on the expression levels of p53, p21, Bcl-2 and Cdc2 in Jurkat-T cells. Lane 1 = control; lane 2 = 10 μg/mℓ; lane 3 = 32.5 μg/mℓ; lane 4 = 40 μg/mℓ. Total cellular proteins were prepared and western blot performed as described in the materials and methods. Note the kinetics of p21 up-regulation which coincided with the up-regulation of p53. β-actin was used as the internal control.Back to article page
