| Popis: | Gene-regulatory network analysis is a powerful approach to elucidate the molecular processes and\ud pathways underlying complex disease. Here we employ systems genetics approaches to characterize the\ud genetic regulation of pathophysiological pathways in human temporal lobe epilepsy (TLE). Using\ud surgically acquired hippocampi from 129 TLE patients, we identify a gene-regulatory network genetically\ud associated with epilepsy that contains a specialized, highly expressed transcriptional module encoding\ud proconvulsive cytokines and Toll-like receptor signalling genes. RNA sequencing analysis in a mouse\ud model of TLE using 100 epileptic and 100 control hippocampi shows the proconvulsive module is\ud preserved across-species, specific to the epileptic hippocampus and upregulated in chronic epilepsy. In\ud the TLE patients, we map the trans-acting genetic control of this proconvulsive module to Sestrin 3\ud (SESN3), and demonstrate that SESN3 positively regulates the module in macrophages, microglia and\ud neurons. Morpholino-mediated Sesn3 knockdown in zebrafish confirms the regulation of the\ud transcriptional module, and attenuates chemically induced behavioural seizures in vivo. |
