COL5A1 and brain cancer: A specific analysis of brain cancer types using Spearman’s correlation coefficient (ρ) revealed that FABP7 expression exhibited strong correlations (p < 0.05, ρ > 0) with the expression of most of its modulated factors in LGG (significantly positive correlations with ENO1, COL5A1, and IL11, and a negative correlation with COL11A1), in contrast to GBM in which little correlation was observed (Figure 2A,B).
