Time(months)
A:The volcano plot showed that 1 672 DEGs were upregulated,while 3 744 DEGs were downregulated. B,E:The difference in mRNAsi(B)and
TCEAL7(E)levels between normal tissues and tumors,respectively. C,F:The Kaplan⁃Meier survival analysis showed a notable difference in OS be⁃
tween the high and low mRNAsi(C)or TCEAL7(F)level groups. D:Pearson correlation analysis illustrated TCEAL7 had a negative correlation with
mRNAsi.

Module membership in blue module
A:The clustering analysis validated eleven various modules,with each color module presenting the same gene expression pattern. B:The green,
blue,purple,black,and pink modules were correlated negatively with mRNAsi,and turquoise,brown and yellow modules were positively correlated with
mRNAsi. C:Scatter plot analysis of blue modules.
