Bisulfite treatment of DNA from fibroblast cells of Aicardi-Goutières syndrome (AGS) patients was performed using the EZ DNA Methylation-Direct Kit prior to MethylC-seq. Results showed a global loss of DNA methylation from patients with TREX1, RNASEH2, and SAMHD1 mutations, indicating epigenetic abnormalities in AGS.Lim YW, et. al. (2015).

In this publication, researchers investigated the regulatory effects of BRCA and glucocorticoid receptor (GR). Genomic DNA extracted from both ovarian cancer and normal ovarian tissue was bisulfite converted using EZ DNA Methylation-Direct Kit and BRCA1 promoter methylation was analyzed. Immunochemistry, real-time PCR, regression analysis, knockdown, and overexpression experiments were also performed to examine the relationship between BRCA1 and GR expression levels, which were found to positively correlate in cancer tissues.Fang YY et al. (2014) Glucocorticoid receptor repression mediated by BRCA1 inactivation in ovarian cancer. BMC Cancer. 14:188.
Epigenetic changes were shown to be induced in the midbrain of adult mice by social isolation from 3-6 months of age. Genomic DNA was isolated from the midbrain of the “lonely” mice and was bisulfite converted using the EZ DNA Methylation-Direct Kit. Bisulfite pyrosequencing was performed and the researchers found that social isolation of adult male C57BL/6 mice led to global DNA methylation changes in the midbrain.Siuda D et al. (2014) Social isolation-induced epigenetic changes in midbrain of adult mice. J Physiol Pharmacol. 65(2):247-55.
