Effect of serotonin 7 receptors and transcript variants on RIN-5F pancreatic beta cell line
Purpose
The physiological effects of 5-HT7 receptors expressed in pancreatic beta cells have not yet been elucidated. We first aimed to investigate the effect of 5-HT7 receptor agonist (AS19) and antagonist (SB269970) application on insulin secretion in RIN-5F pancreatic beta cells. Subsequently, we aimed to investigate the effects of agonist and antagonist applications on cell damage induced by STZ.
Materials/Methods
Cell damage was caused by giving 5 mM STZ solution to the cells for 12 h. The protective effects of 5-HT7 receptor agonist and antagonist on this subsequent damage were investigated. IGF-1, TNF-α, TGF-B1, NF-KB, Bax, Caspase 3, Caspase 9, 5-HT7, 5HT7x2, 5HT7x3 mRNA expression levels were compared between groups.
Results
While agonist application stimulates insulin secretion, the effect of the antagonist varies.SB269970 reduced oxidative stress and downregulated TNF-a, TGF-B1 and NF-KB expression and also prevented apoptosis by decreasing Bax, caspase 3 and 9 levels against STZ-induced beta cell damage.
Conclusions
The effect of 5-HT7 receptors on insulin secretion and their effects against STZ damage will be guiding for more detailed studies in the treatment of diabetes and related diseases in the future.
期刊介绍：
Toxicology in Vitro publishes original research papers and reviews on the application and use of in vitro systems for assessing or predicting the toxic effects of chemicals and elucidating their mechanisms of action. These in vitro techniques include utilizing cell or tissue cultures, isolated cells, tissue slices, subcellular fractions, transgenic cell cultures, and cells from transgenic organisms, as well as in silico modelling. The Journal will focus on investigations that involve the development and validation of new in vitro methods, e.g. for prediction of toxic effects based on traditional and in silico modelling; on the use of methods in high-throughput toxicology and pharmacology; elucidation of mechanisms of toxic action; the application of genomics, transcriptomics and proteomics in toxicology, as well as on comparative studies that characterise the relationship between in vitro and in vivo findings. The Journal strongly encourages the submission of manuscripts that focus on the development of in vitro methods, their practical applications and regulatory use (e.g. in the areas of food components cosmetics, pharmaceuticals, pesticides, and industrial chemicals). Toxicology in Vitro discourages papers that record reporting on toxicological effects from materials, such as plant extracts or herbal medicines, that have not been chemically characterized.
