Abstract:
Objective　To explore the effect of type Ⅳ collagen gene α1 (COL4A1) on the proliferation,metastasis and apoptosis of gastric cancer cells and its potential regulatory mechanism.Methods　The expression of COL4A1 gene in gastric cancer tissues,human normal gastric mucosal epithelial cells GES-1 and gastric cancer cells (SGC-7901,MKN-28,BGC-803,mgc-823,MKN-45 and AGS) was detected by real-time fluorescence quantitative polymerase chain reaction（RT-qPCR）.According to the expression of COL4A1 gene in six gastric cancer cells,AGS and SGC-7901 cells were used for subsequent cell function verification experiments.AGS and SGC-7901 cells were inoculated into 6-well plates.After the fusion reached 90%,the AGS and SGC-7901 cells were divided into control group,negative control (NC) small interfering RNA (siRNA) group,siCOL4A1-1 group,siCOL4A1-2 group and siCOL4A1-2+740 Y-P group.The cells in the control group were cultured normally without any treatment;the cells in NC siRNA group were transfected with NC siRNA,the cells in siCOL4A1-1 group were transfected with siCOL4A1-1,the cells in siCOL4A1-2 group were transfected with siCOL4A1-2,the cells in siCOL4A1-2+740 Y-P group were transfected with siCOL4A1-2,and then were treated with 740 Y-P (50 mg·L-1) for 90 min.The expression of COL4A1 gene in AGS,SGC-7901 cells in the above five groups was detected by RT-qPCR,and the cells in the siCOL4A1-2 group was selected for follow-up experiments according to the detection results.The proliferation of AGS and SGC-7901 cells in control group,NC siRNA group,siCOL4A1-2 group and siCOL4A1-2+740 Y-P group was detected by cell counting kit-8 at 1,2,3,4 days of culture;the apoptosis of AGS and SGC-7901 cells in the four groups was detected by annexin-V/fluorescein isothiocyanate,the migration and invasion ability of AGS and SGC-7901 cells in the four groups were detected by Transwell experiment;the expression of phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) pathway related protein in AGS and SGC-7901 cells was detected by Western blot.Results　The proliferation ability of AGS cells in the siCOL4A1-2 group was significantly lower than that in the control group and the NC siRNA group at 3,4 days of culture (P<0.05);the proliferation ability of SGC-7901 cells in the siCOL4A1-2 group was significantly lower than that in the control group and the NC siRNA group at 1,2,3,4 days of culture (P<0.05).The proliferation ability of AGS cells in the siCOL4A1-2+740 Y-P group was significantly higher than that in the siCOL4A1-2 group at 3,4 days of culture (P<0.05);and the proliferation ability of SGC-7901 cells was significantly higher than that in the siCOL4A1-2 group at 1,2,3 and 4 days of culture (P<0.05).There was no significant difference in the proliferation ability of AGS and SGC-7901 cells among other groups (P>0.05).The apoptosis rates of AGS and SGC-7901 cells in the siCOL4A1-2 group were significantly higher than those in the control group and the NC siRNA group (P<0.05);the apoptosis rates of AGS and SGC-7901 cells in the siCOL4A1-2+740 Y-P group were significantly lower than those in the siCOL4A1-2 group (P<0.05);there was no significant difference in the apoptosis rates of AGS and SGC-7901 cells among other groups (P>0.05).The migration and invasion ability of AGS and SGC-7901 cells in the siCOL4A1-2 group were significantly lower than those in the control group and the NC siRNA group (P<0.05);the migration and invasion ability of AGS and SGC-7901 cells in the siCOL4A1-2+740 Y-P group were significantly higher than those in the siCOL4A1-2 group (P<0.05);there was no significant difference in the migration and invasion ability of AGS and SGC-7901 cells among other groups (P>0.05).There was no significant difference in the values of p-PI3K/PI3K and p-Akt/Akt in AGS and SGC-7901 cells between the control group and the NC siRNA group (P>0.05);the values of p-PI3K/PI3K and p-Akt/Akt in AGS and SGC-7901 cells in siCOL4A1-2 group were significantly lower than those in the control group and the NC siRNA group (P<0.05);the values of p-PI3K/PI3K and p-Akt/Akt in AGS and SGC-7901 cells in siCOL4A1-2+740 Y-P group were significantly higher than those in the siCOL4A1-2 group (P<0.05).Conclusion　Silencing COL4A1 can inhibit the proliferation,migration and invasion and promote apoptosis of gastric cancer cells by inhibiting the activation of PI3K/Akt pathway.
