From: Luteolin decreases IGF-II production and downregulates insulin-like growth factor-I receptor signaling in HT-29 human colon cancer cells

Figure 5

Luteolin inhibits IGF-I-induced Akt activation in HT-29 cells. Cells were plated and treated as described in Figure 4. Total lysates were prepared and immunoblot analyses were conducted with antibodies raised against p-Akt, Akt, or β-actin. (A) Photographs of the chemiluminescent detection of the blots, which were representative of three independent experiments, were shown. (B) The levels of P-Akt to its own Akt control band on immunoblots were quantified via densitometric scanning of the exposed films, and the control levels (0 μmol/L luteolin, without IGF-I stimulation) were set at 1. Each bar represents the mean ± SEM (n = 3). *Different from 0 μmol/L of luteolin at a stimulation time, P < 0.05.
