Figure 6. Correlations between the levels of FGL2 and other genes in ESCA using LinkedOmics. (A) Pearson’s test was used to analyze the correlations between the levels of FGL2 and other genes in ESCA tissues. (B, C) Heatmaps showing the top 50 genes that correlated positively and negatively with FGL2 in ESCA. Positively correlated genes are indicated in red, while negatively correlated genes are shown in blue.
