Background
Colorectal cancer (CRC) is a multifactorial disease and one of the most common malignancies worldwide. Salidroside (Sal) is a plant with a wide range of pharmacological effects and plays an important role in the treatment of many diseases, and is considered a new hope for the treatment of tumors. The
Conclusion
The combined application of Sal and Pac significantly can decrease the survival rate of colorectal cancer cells, and the mechanism may be correlated with the blocking of the PI3K/AKT pathway, thus inhibiting EMT.
Methods
The effects of different mass concentrations of Sal, Pac, and the combination intervened in the cells for 48 h were examined using the CCK8 method. The inhibition rate was obtained, and the optimal concentration of the respective drug group was screened. The proliferative capacity of the respective group was obtained. Subsequently, the
Results
Different concentrations of Sal, Pac, and the combined application had significant effects in inhibiting cells in a concentration-dependent manner. Compared with the control group, the Sal group, the Pac group, and the combination group significantly inhibited the clonal number, migration, invasion, and tube-forming ability of colorectal cancer cells. Besides, the combined application had a better effect than the Sal and Pac groups. The apoptosis level was up-regulated in all drug groups, and the up-regulation was more significant in the combination group. The expression of E-cad protein was up-regulated, the expression of N-cad and Vim protein was down-regulated, and the expression of PI3K and AKT phosphorylation was down-regulated in the respective group, and the difference was more significant in the combination group compared with the group of individual drugs.
