Shaoyao Decoction(芍药汤)is expected to be a candidate prescription for the treatment of colorectal cancer,but its underlying mechanism and molecular targets remain to be explored.
A mouse model of colorectal cancer transplantation was established,and 30 mice were divided into 3 groups:model group(M,n=10),model+Shaoyao Decoction group(SYD,n=10)and model+Shaoyao Decoction+ROSclearance group(SNR,n=10). The mice of the SYD group were given 37 g/kg Shaoyao Decoction by gavage,the mice of the SNR group were given an equal amount of Shaoyao Decoction after intraperitoneal injection of ROSclearance agent,and those of the M group were given the same amount of distilled water. The drug was administered continuously for 21 days. The body weight and tumor volume of mice were observed,ROSlevels in tumors were detected by fluorescence method,and the protein expression in autophagy pathway was detected by western blot.
Shaoyao Decoction inhibited the growth of transplanted colorectal cancer in mice,induced ROSaccumulation in tumor tissues,up-regulated the expressions of Beclin-1,LC3,BIP,PERK and ATG5 proteins,down-regulated the expression of p62 protein,and inhibited the expressions of proteins in PI3K/AKT/mTOR signaling pathway.
Shaoyao Decoction can induce autophagy by promoting excessive accumulation of reactive oxygen species,thus inhibiting the growth of colorectal cancer transplant tumors.
