GAERS Epilepsy Research

Spatiotemporal Transcriptomic Analysis of Epileptogenesis

Funded by TÜBİTAK Project 122S431

Research Overview

593 Bulk RNA-seq DEGs
1,079 Spatial P15 DEGs
2,007 Seizure Genes
8 Spatial Samples

Key Findings

Developmental Changes

Comprehensive analysis revealed 593 differentially expressed genes between pre-seizure (P15) and seizure-onset (P30) stages in the GAERS model, with 94.4% showing upregulation.

Synaptic Organization

Strong enrichment in synaptic plasticity and postsynaptic density organization pathways, indicating critical circuit refinement during the epileptogenic window.

Calcium Signaling

Dysregulation of calcium homeostasis and ion channel genes, including T-type calcium channels critical for absence seizure generation.

About GAERS Model

The Genetic Absence Epilepsy Rats from Strasbourg (GAERS) is a well-established genetic model for studying absence epilepsy. These rats spontaneously develop spike-and-wave discharges (SWDs) characteristic of absence seizures, providing insights into epileptogenesis mechanisms and potential therapeutic targets.
