[Effect of total flavonoids in Scutellaria barbata in mediating autophagy in tumor cells via PI3K/AKT/mTOR pathway].

To investigate the effect of the total flavonoids in Scutellaria barbata(TF-SB) against autophagy in tumor cells in vivo, and further determine whether the mechanism is correlated with the PI3K/AKT/mTOR pathway, which lead to autophagy-induced tumor cell death. Melanoma-bearing mice were prepared and divided into control group, rapamycin group (Rap 1.5 mg•kg⁻¹), and high, middle and low-dose TF-SB (200, 100, 50 mg•kg⁻¹) groups.
