Cytotoxicity of allyl isothiocyanate on insulin-producing INS-1E cells.
Allyl isothiocyanate (AITC) is the pungent ingredient of brassica species, used as a food additive and flavoring agent, including condiments such as wasabi, horseradish, and mustard. Currently, there is much evidence that AITC modulates glucose and lipids metabolism. Interestingly, AITC has been shown to improve glycaemia, and insulin action along with the induction of a deepened decline in blood insulin levels in T2DM rats. Therefore, in the present study, we characterized the role of AITC at a wide concentration range (5, 10, 25, 50, 100 μM) in controlling viability, proliferation, apoptosis, mitochondrial condition, mRNA expression of encoding pancreatic and duodenal homeobox 1 (Pdx1), and Ins1, Ins2 genes, and insulin content in INS-1E cells. The INS-1E cell line is a suitable, and well-characterized model to study beta cell functions. We demonstrate that AITC reduced the viability (p≤0.001) (also in the presence of transient receptor potential cation subfamily A member 1 (TRPA1) selective antagonist; HC-030031; p≤0.05), and proliferation of INS-1E cells (p≤0.001). AITC evoked a significant reduction of mitochondrial membrane potential (p≤0.01) and decreased the intracellular level of adenosine triphosphate (ATP) (p≤0.001) without influence on reactive oxygen species (ROS) level. Additionally, AITC inhibited the insulin mRNA expression (p≤0.001) in INS-1E cells along with insulin content (p≤0.05). Mitochondrial dysfunction is proposed to be a significant disruption mechanism of AITC in INS-1E cells, and it was independent of ROS, and the influx of external calcium.
期刊介绍:
Journal of Physiology and Pharmacology publishes papers which fall within the range of basic and applied physiology, pathophysiology and pharmacology. The papers should illustrate new physiological or pharmacological mechanisms at the level of the cell membrane, single cells, tissues or organs. Clinical studies, that are of fundamental importance and have a direct bearing on the pathophysiology will also be considered. Letters related to articles published in The Journal with topics of general professional interest are welcome.
