Project description:Cannabidiol (CBD) oral spray on murine oral ulcer significantly inhibited inflammation, relieved pain and accelerated healing process. To gain insight into transcriptional regulation of CBD on cells related to healing progress of oral ulcer, we performed RNA-Seq on the immortalized human oral keratinocyte HOK-16B cell lines stimulated with LPS and ATP, after 10μM CBD or vehicle excipient pretreatment.
Project description:Primary human keratinocytes cultures were incubated with either DMSO or cannabidiol (10 uM) for 24 hours (N=4) to evaluate the effect of this compound over skin cells.
Project description:In this study we aim to determine the role of IL-4/STAT6 in gene expression in human keratinocytes using RNA-sequencing approach. Human keratinocytes were cultured for 2 or 5 days with calcium chloride to induce terminal differentiation as determined by the expression of epidermal differentiation complex genes. The cells were then stimulated with IL-4 for 3 and 24 hours, or along the 5 days culture period. We observed that IL-4 inhibits fully differentiation of keratinocytes, induces genes involved with production of inflammatory mediators, and reduces the healing capacity of human keratinocytes. Moreover, STAT6 controlled important genes involved with calcium binding, inflammation and epidermis development. Human keratinocytes were differentiated with calcium chloride for 2 days and incubated with media alone or 20ng/ml of recombinant human IL-4 for 3 and 24 hours. Human keratinocytes were differentiated with calcium chloride for 5 days with or wihout recombinant human IL-4 (20ng/ml). Keratinocytes transfected with control or STAT6 siRNA were differentiated with calcium chloride for 2 days and then stimulated with recombinant huma IL-4 for 24 hours.
Project description:In the current study, we aimed at exploring the effects of the major non-psychotropic phytocannabinoid of Cannabis sativa, (-)-cannabidiol (CBD), on human sebaceous gland functions. We found that CBD behaved as a highly effective anti-acne agent, targeting all the three key, sebocyte-specific steps of the pathogenesis (i.e. without compromising viability or basal sebaceous lipid production, CBD normalized pro-acne agents-induced excessive lipid synthesis, reduced proliferation and exerted anti-inflammatory actions). The goal of the present microarray analyses was to identify signaling pathways and target genes being involved in mediating the above beneficial effects of CBD.

The goal of the present microarray analyses was to identify signaling pathways and target genes being involved in mediating the above beneficial effects of CBD. Microarray analyses were performed by using three independent sets of control (vehicle-treated) and CBD-treated (10 M-NM-<M, 24-hr) human, immortalized SZ95 sebocytes. The first two sets of the samples were analyzed by two-color microarrays (M-bM-^@M-^\rep1M-bM-^@M-^] and M-bM-^@M-^\rep2M-bM-^@M-^]). Later on, the RNA from the second sample set was used for the M-bM-^@M-^\rep2-1M-bM-^@M-^] hybridization (techical repeat). Finally, we analyzed the third (biological) sample set by using one-color microarray (M-bM-^@M-^\rep3M-bM-^@M-^]).

Project description:The non-psychotomimetic phytocannabinoid cannabidiol (CBD) has shown anticonvulsant effects in several seizure models in rats and mice. However, the mechanisms by which CBD exerts its antiepileptic effects are not fully elucidated. MicroRNAs (miRNA) are short non-coding RNAs which regulate protein expression. Dysregulation of miRNAs can contribute to the pathology of various diseases, including epilepsy. This could indicate that the modulation of miRNAs is a potential mechanism of action for the therapeutic effects of CBD. Therefore, we sequenced hippocampal samples from CBD or vehicle treated naive mice to see the effects of CBD on miRNA expression.
