Non-alcoholic fatty liver disease (NAFLD), a pervasive obesity-related disease, is recognized as the most prominent liver disease in the world (Eslam, 2018). NASH is defined when inflammation is associated with hepatic steatosis, and is induced through a methionine/ choline deficient (MCD) diet (Lee, 2007). Current research is focused on global methylation rates, which represents the addition of a methyl group at various CpG dinucleotide sites. DNA methylation functions as a gene silencer, so global hypermethylation is associated with NASH pathology. However, how the DNA methylation on specific genes would affect the outcome of NASH is unclear. I intend to determine whether cannabigerol (CBG), a non-psychotropic cannabinoid, has either a hypo- or hyper-methylational effect on four genes of focus using MCD-induced NASH liver tissue. These four genes include CDKN1A, BMAL1, PPARgamma, and PNPLA3, all of which have potential pathological effects regarding NAFLD. My research question is: what is the hypo/hyper-methylation rates effect on promoter regions CDKN1A, BMAL1, PPARalpha, and PNPLA3 with CBG implementation utilizing a mouse model with MCD diet to induce NASH? Using frozen mice liver tissue, I will perform a methylation-specific polymerase chain reaction (PCR) to amplify promoter regions of the four genes. Then, I will utilize gel-electrophoresis to check whether the promoter region is methylated or unmethylated. Each of the four genes will be examined under four conditions, providing 16 data points of analysis: control diet, control diet and CBG, MCD diet, and MCD diet and CBG. I hypothesize that first, MCD diet will hyper-methylate my four genes of focus as compared to the control diet. Therefore, the four genes will be more inhibited for the MCD diet group. Second, I hypothesize that the CBG implementation will decrease the local methylation rates at my four focus genes.
