Among these, known biomarkers for MB (FSTL5 [31]), and other tumor types such as neuroendocrine tumors (ENO2 [32], FMOD [33], ART3 [34], COL6A3 [35]) and PIP [36], were found to be significantly up-regulated (Figure 3B, dark green). This evidence concerns the gene FSTL5 and neuroendocrine neoplasm.
