Genes, Proteins, and Metabolites in Drug-resistant Epilepsy (DRE) Patients

Genomical studies have identified changes in the expression of certain genes within epileptic tissues. These genes may be involved in pathways related to the balance of neuronal excitability and inhibition, synaptic transmission, and cell apoptosis.

Proteomic studies will reveal changes in the abundance and modifications of proteins in epileptic tissues. These could involve proteins related to the control of neuronal excitability and synaptic transmission, such as ion channels, neurotransmitter receptors, and synaptic proteins.

Metabolomic researches will reveal changes in metabolites within epileptic tissues. Epilepsy may lead to disruptions in metabolic pathways, affecting key processes such as energy metabolism, amino acid metabolism, and lipid metabolism.

Sample Size: There is no minimum or maximum, but is expected to be far less than 10.

In summary, patients with drug-resistant epilepsy might have changes in genes, proteomics, and metabolomics within epileptic tissues compared to normal tissue from TBI. Further research into these changes will deepen our understanding of the pathophysiology of epilepsy and guide the need for new treatment strategies.
