OriGene human gabaa receptor α1
Fig. 2. Whole-cell patch-clamp recording of selected eight <t>GABAA</t> receptor <t>α1</t> subunit DAVs. a HEK293T cells were transiently transfected with α1 (wild type or the indicated variants), β2, and γ2 cDNAs of GABAA receptors. Forty-eight hours post transfection, whole-cell currents were recorded using the IonFlux Mercury 16 ensemble plates at a holding voltage of −60 mV. Representative whole-cell voltage-clamp recording traces are shown. Application of GABA (100 μM, 3 s) is indicated by the horizontal bar above the current traces. Quantification of the peak currents (Imax) is shown on the right (n = 4–10). nA: nano Ampere. b Dose-response curves of GABA are shown for the calculation of EC50 values for wild type and the indicated α1 DAVs (n = 3–4). Each data point is reported as mean ± SEM. One-way ANOVA followed by post-hoc Tukey test was used for statistical analysis. Statistical significance was labelled for the comparison to the WT group. ***, p < 0.001.

Fig. 8. Proposed mechanism of action of Hispidulin and TP003 on rescuing α1 DAV trafficking. Hispidulin and TP003 act as pharmacological chaperones to bind GABAA receptor variants to stabilize them in the ER. Pharmacological chaperone treatment enhances the assembly of the variants and their forward trafficking to the Golgi and plasma membrane. The effect of Hispidulin and TP003 is also reflected from the enhanced folding and reduced degradation of the variants. Consistently, the interactions between the variants and pro-folding chaperones (BiP and calnexin) and a trafficking factor (LMAN1) are enhanced, whereas the interactions be tween the variants and ERAD factors (Grp94 and VCP) are reduced by pharmacological chaperone treatment.
