Figure Lengend Snippet: WB analyses of biochemically isolated fractions from primary SoCx for GABA A R α4, α5, and δ subunits. Subcellular fractions were isolated from the control (NE) littermates and epileptic epileptic (E) stargazers. ( A – D ) Biochemical fractionation analysis revealed no significant change in GABA A R α4 in all subcellular components from the primary SoCx of stargazers compared to their NE littermates: total lysate (NE: 1.000 ± 0.063 [ n = 9], E: 1.353 ± 0.227 [ n = 9]; p = 0.257), cytosol (NE: 1.000 ± 0.088 [ n = 14], E: 1.308 ± 0.223 [ n = 10]; p = 0.172), extra-synaptic (NE: 1.000 ± 0.051 [ n = 14], E: 0.789 ± 0.183 [ n = 9]; p = 0.516), and synaptic (NE: 1.000 ± 0.047 [ n = 14], E: 0.955 ± 0.122 [ n = 9]; p = 0.369). ( E – H ) GABA A R α5 analysis revealed no significant change in all subcellular components from the primary SoCx of stargazers compared to their control littermates: total lysate (NE: 1.000 ± 0.094 [ n = 10], E: 0.919 ± 0.102 [ n = 10]; p = 0.566), cytosol (NE: 1.000 ± 0.113 [ n = 14], E: 1.295 ± 0.362 [ n = 8]; p = 0.920), extra-synaptic (NE: 1.000 ± 0.068 [ n = 13], E: 1.324 ± 0.214 [ n = 9]; p = 0.431) and, synaptic (NE: 1.000 ± 0.075 [ n = 13], E: 1.190 ± 0.195 [ n = 9]; p = 0.744). ( I – L ) No statistically significant change was also seen for GABA A R δ subunit in all subcellular components from the primary SoCx of stargazers compared to their control littermates: total lysate (NE: 1.000 ± 0.071 [ n = 15], E: 1.088 ± 0.201 [ n = 9]; p = 0.815), cytosol (NE: 1.000 ± 0.083 [ n = 15], E: 0.831 ± 0.138 [ n = 9]; p = 0.379), extra-synaptic (NE: 1.000 ± 0.078 [ n = 15], E: 1.419 ± 0.241 [ n = 10]; p = 0.191), and synaptic (NE: 1.000 ± 0.053 [ n = 15], E: 1.092 ± 0.094 [ n = 9]; p = 0.263). The significance threshold was set at 0.05. ‘ns’ indicates no significant change found from analyses.
