There were nine clusters, such as cluster 0 (SCI), cluster 1 (synaptic plasticity), cluster 2 (activation), cluster 3 (epilepsy), cluster 4 (ketamine), cluster 5 (AD), cluster 6 (activated protein kinase), cluster 7 (gene expression), and cluster 8 (neuroendocrine tumors). This evidence concerns the gene WEE1 and Alzheimer disease.
