Human consumption of cannabinoid-containing products during early life or pregnancy is rising. However, information about the molecular mechanisms involved in early life stage Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) toxicities is critically lacking. Here, larval zebrafish (Danio rerio) were used to measure THC- and CBD-mediated changes on transcriptome and the roles of cannabinoid receptors (Cnr) 1 and 2 and peroxisome proliferator activator receptor γ(PPARγ) in developmental toxicities. Transcriptomic profiling of 96-h postfertilization (hpf) cnr+/+ embryos exposed (6 - 96 hpf) to 4 μM THC or 0.5 μM CBD showed differential expression of 904 and 1095 genes for THC and CBD, respectively, …


The Role Of Cannabinoid Receptor 2 In Zebrafish Toxicities Following Developmental Exposure To Thc Or Cbd, Haley Watts May 2021

The Role Of Cannabinoid Receptor 2 In Zebrafish Toxicities Following Developmental Exposure To Thc Or Cbd, Haley Watts

Honors Theses

As the laws concerning the regulation of Cannabis Sativa change across the globe, maternal use of cannabinoid-containing products during pregnancy is a greater concern than ever before. Little research has been conducted on the consequences of maternal use and developmental exposure to ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD. In this study, larval zebrafish (Danio rerio) were used to measure CBD and THC-mediated adverse outcomes including effects on larval length, eye area, and behavior in the cnr+/+ and cnr2-/- zebrafish strains where we discovered that cannabinoid exposure results in a decrease in each of these endpoints. Adult …
