Abstract
Since the passage of the 2018 Agriculture Improvement Act (2018 Farm Bill), the number of products containing cannabis-derived compounds available to consumers have rapidly increased. Potential effects on liver function as a result from consumption of products containing cannabidiol (CBD), including hemp extracts, have been observed but the mechanisms for the effects are not fully understood. In this study, hepatocytes derived from human induced pluripotent stem cells (iPSCs) were used to evaluate potential hepatic effects of CBD and hemp extract at exposure concentrations ranging from 0.1 to 30 μM. Despite that a significant reduction in cell viability occurred only in the 30 μM group for both CBD and hemp extract, significant changes to cytochrome P450 activity, mitochondrial membrane potential, and lipid accumulation occurred within the concentration range of 0.1–3 μM for both CBD and hemp extract. Albumin and urea production, caspase 3/7 activity, and intracellular glutathione were significantly affected within the concentration range of 3–30 μM by CBD or hemp extract. These findings indicate that CBD and hemp extract can alter hepatic function and metabolism. The current study contributes data to help inform the evaluation of potential hepatotoxic effects of products containing cannabis-derived compounds.
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.
