LE 135 26-31 transient receptor potential cation channel subfamily A member 1 Homo sapiens 235-240 24308840-4 2014 EXPERIMENTAL APPROACH: We performed to investigate the excitatory effects of LE135 on TRPV1 and TRPA1 channels expressed in HEK293T cells and in dorsal root ganglia neurons with calcium imaging and patch-clamp recordings. LE 135 77-82 transient receptor potential cation channel subfamily A member 1 Homo sapiens 96-101 24308840-5 2014 We also used site-directed mutagenesis of the channels to determine the structural basis of LE135-induced activation of TRPV1 and TRPA1 channels and behavioural testing to examine if pharmacological inhibition and genetic deletion of the channels affected LE135-evoked pain-related behaviours. LE 135 92-97 transient receptor potential cation channel subfamily A member 1 Homo sapiens 130-135 24308840-6 2014 KEY RESULTS: LE135 activated both the capsaicin receptor (TRPV1) and the allyl isothiocyanate receptor (TRPA1) heterologously expressed in HEK293T cells and endogenously expressed by sensory nociceptors. LE 135 13-18 transient receptor potential cation channel subfamily A member 1 Homo sapiens 104-109 24308840-9 2014 Both TRPV1 and TRPA1 channels were involved in LE135-elicited pain-related responses, as shown by pharmacological and genetic ablation studies.
