Abstract:
Objective To investigate the effects of long intergenic non-coding RNA 467(linc00467)on the proliferation,apoptosis and migration,invasion ability of endometrial carcinoma cells.Methods Human endometrial carcinoma cells HC1A,Ishikawa,KLE and RL-95-2 were cultured in vitro,the expression level of linc00467 in the four cells was detected by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR).Endometrial carcinoma cell lines HEC-1A and Ishikawa with the highest linc00467 expression levels were selected for subsequent experiment.Two Iinc00467 lentivirus silencing expression vectors of sh-linc00467#1 and sh-linc00467#2,and empty lentivirus plasmids were constructed,respectively;the HEC-1A and Ishikawa cells in logarithmic growth phase were divided into sh-NC group,sh-linc00467#1 group,and sh-linc00467#2 group.The cells in the sh-NC group were transfected with empty lentivirus plasmids,the cells in the sh-linc00467#1 group and sh-linc00467#2 group were transfected with sh-linc00467#1 and sh-linc00467#2,respectively;the relative expression level of linc00467 in cells of the three groups was detected by RT-qPCR,the proliferation ability of cells in the three groups was detected by 5-ethynyl-2-deoxyuridine(EdU)assay and colony formation assay,the migration ability of cells in the three groups was detected by scratch assay,the invasion ability of cells in the three groups was detected by Transwell assay,and the cell apoptosis in the three groups was detected by flow cytometry.Results The relative expression level of linc00467 mRNA in HEC-1A cells was significantly higher than that in KLE and RL-95-2 cells(P＜0.05);the relative expression level of linc00467 mRNA in Ishikawa cells was significantly higher than that in KLE and RL-95-2 cells(P＜0.05);there was no statistically significant difference in the relative expression level of linc00467 mRNA between HEC-1A and Ishikawa cells(P＞0.05);the relative expression level of linc00467 mRNA in KLE cells was significantly lower than that in RL-95-2 cells(P＜0.05).The relative expression levels of linc00467 mRNA in HEC-1A and Ishikawa cells in the sh-linc00467#1 group and sh-linc00467#2 group were significantly lower than those in the sh-NC group(P＜0.01);there was no statistically significant difference in the relative expression level of linc00467 mRNA in HEC-1A and Ishikawa cells between the sh-linc00467 # 1 group and the sh-linc00467#2 group(P＞0.05).The number of EdU positive HEC-1A and Ishikawa cells in the sh-linc00467#1 group and sh-linc00467#2 group was significantly lower than that in the sh-NC group(P＜0.01);there was no statistically significant difference in the number of EdU positive HEC-1A and Ishikawa cells between the sh-linc00467#1 group and sh-linc00467#2 group(P＞0.05).The number of cloned HEC-1A and Ishikawa cells in the sh-linc00467#1 group and sh-linc00467#2 group was significantly lower than that in the sh-NC group(P＜0.01);there was no statistically significant difference in the number of cloned HEC-1A and Ishikawa cells between the sh-linc00467#1 group and sh-linc00467#2 group(P＞0.05).The apoptosis rates of HEC-1A and Ishikawa cells in the sh-linc00467#1 group and sh-linc00467#2 group were significantly higher than that in the sh-NC group(P＜0.01);there was no statistically significant difference in the apoptosis rates of HEC-1A and Ishikawa cells between the sh-linc00467#1 group and sh-linc00467 #2 group(P＞0.05).The scratch healing rates of HEC-1A and Ishikawa cells in the sh-linc00467#1 group and sh-linc00467#2 group were significantly lower than those in the sh-NC group(P＜0.01);there was no statistically significant difference in the scratch healing rates of HEC-1 A and Ishikawa cells between the sh-linc00467#1 group and sh-linc00467#2 group(P＞0.05).The number of invasive cells of HEC-1 A and Ishikawa in the sh-linc00467#1 group and sh-linc00467#2 group was significantly lower than that in the sh-NC group(P＜0.01);there was no statistically significant difference in the number of invasive cells of HEC-1 A and Ishikawa between the sh-linc00467#1 group and sh-linc00467#2 group(P＞0.05).Conclusion Down-regulation of linc00467 expression can inhibit the proliferation,migration and invasion,and promote apoptosis of endometrial carcinoma cells.
