The observed regulatory roles of the α7nAChR for the production of noradrenaline and of the α4β2nAChR for the production of GABA by NSCLC cells are analogous to the function of these receptors in the brain where noradrenaline has excitatory effects, whereas GABA acts as the main inhibitory neurotransmitter [13], [14]. Here, CHRNA7 is linked to non-small cell lung carcinoma.
