The mRNA expression of 16 hub genes in different tumor stage of TCGA patients. The stage III and stage IV were set high degree stage group and the stage I and stage II were set low degree stage group. The Wilcoxon test was done between the two groups. The genes whose P-value ranked from low to high were as follows: a COL6A3. b CDH11. c COL8A1. d NTM. e COL11A1. f MMP2. g BGN. h COL1A1. i COL5A1. j COL3A1. k PXDN. l THBS2. m COL1A2. n THY1. o AEBP1. p TGFB1I1. Except for the expression of TGFB1I1, others were significant in distinguishing low and high tumor stage (P-value< 0.05)
