MTSS1 located in the central position of the gene function net of residual HCC. a the cluster heat map of gene cluster (vertical) and sample cluster (horizontal) were based on tumor-related genes in HCC. The color red and green represents high and low gene expression, respectively; samples with expression above mean level (red) are clustered. Gene function nets of HCC were constructed successfully. b gene function nets of HCC from palliative resection group (HCC tissues T1). c gene function nets of HCC from sham operation group (HCC tissues T2). d gene function nets of HCC from blank control group (HCC tissues T3). e gene function nets shown that MTSS1 was located in the central position of the gene function net of residual HCC (HCC tissues T4). f the density value of the gene function net. g the condensation degree of the net. h qRT-PCR analysis shown that palliative resection up-regulated MTSS1 expression, *P = 0.001, 0.034, and 0.002, respectively, when compared with controls (T1, T2, and T3 groups). The bars indicate the means ± s.d
