RNA-seq of CBD-treated SK-N-BE(2) cells over a time course of 3hr - 24hr with vehicle (ethanol) matched controls at each time point.

ABSTRACT: Cannabidiol (CBD) is an FDA approved drug for treatment of drug-intractable forms of pediatric epilepsy. While a unified mechanism of action has yet to emerge from numerous proposed molecular targets of CBD, preclinical studies reveal a pleiotropic pharmacology. Here, we report the application of temporally-resolved multi-omic profiling and biosensor screening to dissect the molecular mechanism of CBD in human neuroblastoma cells. CDB treatment led to a rise in cytosolic calcium and activation of AMPK signaling within 2 hours. Subcellular profiling of proteins, metabolites, and mRNA transcripts identified CBD-dependent activation of cholesterol biosynthesis, transport and storage. We found that CBD incorporates into cellular membranes, alters cholesterol activity, and increases lipid order. We also report CBD-induced apoptosis in multiple human cell lines, which is rescued by statins and potentiated by compounds that disrupt cholesterol trafficking and storage. Our data point to pharmacological interaction of CBD with cholesterol homeostasis pathways, with potential implications in its therapeutic use.

Effects of CBD on the glioma stem cell molecular signature

Project description:Primary glioma stem cells cultured as neurospheres in NBL media with growth factors were subjected to treatment with the non-toxic, non-psychoactive cannabis compound cannabidiol (CBD). Control and CBD- treated cultures were used to generate RNA used to hybridize on Affymetrix DNA arrays Fluorescence intensities data were RMA-normalized using Partek software.

Elucidating the transcriptomic response of adult hypothalamic neuron cells to cannabidiol (CBD) exposure

Project description:Cannabidiol (CBD) actions in the brain are largely complex and not fully understood. One important brain structure that is a target for CBD, and for which health-beneficial CBD consequences can be seen is the hypothalamus. Given the fundamental role of gene expression in the hypothalamus's regulatory functions, this study undertook the analysis of changes arising in hypothalamic cells’ transcriptomes following various CBD treatments. For this purpose, we used a hypothalamic cellular model, namely we employ adult-derived mHypoA-2/12 mouse cell lines. In the course of the study, the neural cells were treated with different CBD doses (ranging from 0.325 to 3 µM) and vehicle as a control for 6 and 24 hours. The experiment setup allowed us to evaluate both the dosage and time-dependent effect of CBD on hypothalamic cells, particularly on their viability, apoptosis, and transcriptome profile.

Canabidiol (CBD) modulates the effect of ethanol on the fibroblast cells transcriptome in vitro

Project description:Considering reports about positive role of Cannabidiol (CBD) in alcohol abuse disorders, in this study we used cellular model of human fibroblasts to analyse the effect of CBD on ethanol-treated cells. We assumed, that CBD will (to some extent), prevent adverse transcriptional changes driven by alcohol administration and this effect will be detectable on the transcriptome level. As a by-product of this analysis, ethanol and CBD alone stimulated transcriptome changes were also described. We moreover considered that CBD effects are dose and time-dependent. As a model for these analyses we selected human fibroblast cell line as a most abundant cell type in human body that express e.g. both cannabinoid receptors (CB1 and CB2) and is able to metabolize ethanol trough alcohol dehydrogenase activity.

On the way to elucidate the effects of cannabidiol (CBD) on living organisms - assessment of changes in the global transcription profile of liver in mouse model

Project description:Cannabidiol (CBD) is a phytocannabinoid that has anti-inflammatory, immunomodulatory, antioxidant, anxiolytic, antipsychotic, and anticonvulsant effects. The metabolism of CBD occurs in the liver within a few hours after the dose is administered. This study aims to examine the effects of CBD on behavior, immune system activity, and stress levels, and to determine its impact on transcriptomic alterations in selected murine organs.

Oral CBD treatment is associated to an anti-inflammatory gene expression signature in myeloid cells of people living with HIV

Project description:HIV-related comorbidities appear to be related to chronic inflammation, a condition characterizing people living with HIV (PLWH). Prior work indicates that cannabidiol (CBD) might reduce inflammation; however, the genetics underpinning this effect are not well investigated. Our main objective is to detect gene expression alterations in human peripheral blood mononuclear cells (PBMCs) from PLWH after at least one month of CBD treatment. We collected PBMCs from three HIV-positive subjects at baseline and after CBD treatment (at least 27 days) via single-cell RNA sequencing. We obtained a coherent signature, characterized by an anti-inflammatory activity, of differentially expressed genes in myeloid cells. Our study shows how CBD is associated with alterations of gene expression in myeloid cells after CBD treatment.

Elucidating The Role Of ∆9-Tetrahydrocannabinol (Thc) And Cannabidiol (Cbd) In Developmental Toxicity

Project description:Increased availability of cannabis and cannabinoid-containing products necessitates the need for understanding how exposure to these compounds can affect development. Using cannabinoid receptor-null zebrafish (cnr1-/- and cnr2-/-), we conducted experiments to assess the roles of these receptors in ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD) developmental and behavioral toxicity. THC increased mortality and deformities (pericardial and yolk sac edemas, a reduction in size) in cnr1-/- and cnr2-/- fish. Conversely, CBD-induced malformations and mortality were significantly reduced in the cnr1-/- and cnr2-/- larvae. THC and CBD exposure caused significantly decreased larval behavior (96 hpf), however, decreased distance travelled was protected in the cnr1-/- and cnr2-/- fish, suggesting these receptors are responsible for mediating behavioral toxicity. Transcriptomic profiling in cnr+/+ embryos developmentally exposed to 4 μM THC or 0.5 μM CBD revealed that a significant portion of differentially expressed genes were targets of PPARγ, a predicted upstream regulator. In Cnr-positive embryos, co-exposure to the PPARγ inhibitor GW9662 and THC or CBD, there was increased toxicity compared to exposure with THC or CBD alone. Co-treatment in the cnr2-/- fish with GW9662 did not alter the CBD-induced decrease in activity. However, co-treatment with GW9662 did remove the protective effect observed in cnr1-/- fish treated to CBD alone. Collectively, these results indicate that PPARγ, Cnr1, and Cnr2 all play crucial roles in the developmental toxicity of THC and CBD.

Proteome-wide profiling using sample multiplexing of a human neuroblastoma SH-SY5Y cell line treated with cannabidiol (CBD) and tetrahydrocannabinol (THC)

Project description:Cannabis has been used throughout history for medicinal and recreational purposes. The most notable cannabinoids derived from these plants are cannabidiol (CBD) and tetrahydrocannabinol (THC). Although well studied for their therapeutic effects, and highly debated concerning their recreational use, the underlying mechanisms of their biological effects are poorly defined. Here we used isobaric tag-based sample multiplexed proteome profiling to investigate protein abundance differences in the human neuroblastoma SH-SY5Y cell line treated with CBD and THC. We highlighted significantly regulated proteins by each treatment and performed pathway classification and associated protein-protein interaction analysis. Our data suggest that these treatments may result in mitochondrial dysfunction and induce endoplasmic reticulum stress. This dataset can be mined further to investigate the potential role of CBD and THC in various biological and disease contexts and thus provide a foundation for future studies.
