Effect of Guben Jiedu Prescription-medicated Serum on Epithelial-mesenchymal Transition of Lung Cancer A549 Cells: Based on PI3K/Akt Signaling Pathway
To observe the effect of Guben Jiedu prescription (GBJ) on the epithelial-mesenchymal transition (EMT) of lung cancer A549 cells and to explore the mechanism based on phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway.
Method
2
The GBJ-medicated serum was prepared. Cell viability was detected by methyl thiazolyl tetrazolium (MTT) assay to screen the optimal doses of GBJ-medicated serum for further experiment. A549 cells were classified into normal serum group, low-, medium-, and high-dose GBJ-medicated serum groups (2.5%, 5%, and 10% GBJ-medicated serum), PI3K/Akt pathway activator SC79 group, and high-dose GBJ-medicated serum + SC79 group. Cell migration ability was measured by wound-healing assay. The protein expression of E-cadherin, N-cadherin, vimentin, Akt, phosphorylated Akt (p-Akt), glycogen synthase kinase-3
β
(GSK-3
β
), and phosphorylated GSK-3
β
(p-GSK-3
β
) was detected by Western blotting, and the mRNA expression of N-cadherin and vimentin by Real-time PCR.
Result
2
Compared with the normal serum, GBJ-medicated serum (2.5%, 5%, 10%, 20%, 40%) decreased the viability of A549 cells (
P
<
0.05), and 10%, 5%, 2.5% GBJ-medicated serum was respectively selected for the follow-up experiment. The migration ability of cells in the high-, medium-, and low-dose GBJ-medicated serum groups was lower than that in the normal serum group. The expression of N-cadherin mRNA and Vimentin mRNA in A549 cells in the three GBJ-medicated serum groups was significantly lower than that in the normal serum group (
P
<
0.01). The protein expression of E-cadherin was higher in the high- and medium-dose GBJ-medicated serum groups than in the normal serum group (
P
<
0.01). The three GBJ-medicated serum groups showed lower protein expression of N-cadherin, vimentin, p-Akt, and p-GSK-3
β
(
P
<
0.01) and lower expression of p-Akt/Akt, p-GSK-3
β
/GSK-3
β
(
P
<
0.05,
P
<
0.01) than normal serum group. Compared with the SC79 group, the high-dose GBJ-medicated serum group demonstrated high protein expression of E-cadherin (
P
<
0.01) and low expression of N-cadherin, vimentin, p-Akt, p-GSK-3
β
, and p-Akt/Akt, p-GSK-3
β
/GSK-3
β
(
P
<
0.01). Compared with the high-dose GBJ-medicated serum group, high-dose GBJ-medicated serum + SC79 group showed low protein expression of E-cadherin (
P
<
0.01) and high protein expression of N-cadherin, vimentin, p-Akt, p-GSK-3
β
, p-Akt/Akt, and p-GSK-3
β
/GSK-3
β
(
P
<
0.01).
Conclusion
2
GBJ can inhibit the migration and EMT of lung cancer A549 cells by regulating the PI3K/Akt signaling pathway.
