In MB, Pajtler et al. [41] found that the histone demethylase LSD1/KDM1A is functionally involved in the regulation of the malignant phenotype of medulloblastoma cells by influencing three major hallmarks of cancer cells, uncontrolled cell proliferation, the avoidance of apoptosis, and migratory capacity. The gene discussed is KDM1A; the disease is medulloblastoma.
