AIMS: This study established the in vitro anti-lymphoma pharmacodynamic actions of the endocannabinoids (anandamide-AEA and 2-arachidonoylglycerol-2AG) on canine non-Hodgkin lymphoma (NHL) and human NHL cells.
MAIN METHODS: The expression of cannabinoid (CB1 and CB2) receptors in various canine NHL cells {1771, CLBL-1, CLL-1, peripheral blood mononuclear cells (PBMCs)} was studied using Quantitative real-time PCR (RT-qPCR). Anti-lymphoma cell viability assay was performed to assess the effect of endocannabinoids on various canine and human NHL cells (1771, CLBL-1, CLL-1, Ramos cells). The spectrophotometric and fluorometric procedures evaluated oxidative stress, inflammation, apoptosis, and mitochondrial function markers. SAS® and Prism-V La Jolla, CA, USA, were used for statistical analysis.
KEY FINDINGS: The current study validated the presence of CB1 and CB2 receptors in the canine NHL cells. There was a significantly higher expression of CB1 and CB2 receptors in B-cell lymphoma (BCL) cells (1771, CLBL-1, Ramos) compared to canine T-cell lymphoma (TCL) cells (CL-1). AEA and 2AG dose and time-dependently exhibited significant but differential anti-lymphoma effects on canine and human NHL cells. Anti-lymphoma pharmacodynamic actions of the endocannabinoids in the canine 1771 NHL cells revealed a significant alteration in the markers of oxidative stress, inflammation, and a decrease in mitochondrial function without altering the apoptotic markers.
SIGNIFICANCE: Establishing the anti-lymphoma pharmacodynamic actions of endocannabinoids may provide new therapeutic interventions and expedite cannabinoid research.
