“In vitro exposure of cells to single doses or seven days of nicotine induced the protein expression of MMP-2, MMP-9 and EGR-1 and these responses were blocked by GABA.”
“Interestingly, GABA , being an antagonist to cAMP signaling, showed a promising intervention by reversing the stimulatory effect of nicotine on cancer growth and all signaling pathways.”

“Accordingly, pharmacological agents that target brain acetylcholine, DA, glutamate, GABA , or endocannabonoid signaling systems have been proposed to interrupt nicotine action.”
“ Nicotine treatment also down-regulated expression of the GABA synthesizing enzyme GAD 65 and the level of endogenous GABA, while treatment of NSCLC cells with GABA inhibited cell proliferation.”
“All of the observed adverse effects of chronic nicotine were reversed by treatment of the cells with γ-aminobutyric acid , suggesting the potential usefulness of this agent for the improvement of PDAC intervention strategies in smokers.”
“Second, we discuss preclinical evidence that suggests nicotine affects GABA neuronal function indirectly by a primary action at neuronal nicotinic acetylcholine receptors.”
