Among multiple epigenetic modifications, DNA cytosine methylation has been most reliably studied in experimental and clinical settings (Olkhov-Mitsel and Bapat, 2012; Klengel et al., 2014). Intergenerational effects of war trauma among Palestinian families mediated via psychological maltreatment.
Studies attempting to understand stress-dependent developmental programming, have largely focused on promoter methylation of stress-regulatory genes, such as the glucocorticoid receptor (GR) gene, in association with vulnerability and resilience to psychiatric disorders (Daskalakis et al., 2013). doi: 10.1002/cam4.22 Pubmed Abstract | Pubmed Full Text | Cross Ref Full Text | Google Scholar Palosaari, E., Punamaki, R.
More studies examined methylation in this region (Moser et al., 2007; Alt et al., 2010; Radtke et al., 2011; Mulligan et al., 2012; Steiger et al., 2013; Yehuda et al., 2013, 2014a; Rodney and Mulligan, 2014), but only the above 16 report methylation differences at a single Cp G site resolution. Methylation changes at NR3C1 in newborns associate with maternal prenatal stress exposure and newborn birth weight. doi: 10.4161/epi.21180 Pubmed Abstract | Pubmed Full Text | Cross Ref Full Text | Google Scholar Na, K.
It is already becoming clear that different studies use different methodologies, examine slightly different sub-regions, and accordingly, produce different findings with respect to directionality of the associations with stressful experience and stress-related illness (Figure 2).
The coverage of every study is represented with a gray box and the direction of the site-specific findings is also depicted (▴ for hypermethylation, ▾ for hypomethylation, ▴▾ for both hyper- and hypo- methylation).
The sex distribution, age group of participant at assessment and type of collected tissue are indicated in the left, while the method of quantitative methylation analysis used is indicated on the right.
Furthermore, CD82 blockade by a specific antibody downregulated BCL2L12 in parallel with dephosphorylation of signal transducer and activator of transcription 5 (STAT5) and AKT, whereas pharmacological inhibition of STAT5 and AKT activation decreased BCL2L12 expression in leukemia cells.The first of these studies examined the rat hippocampal GR exon 1 promoter methylation showing an association with variation in maternal care the first week of life particularly at the nerve growth factor-inducible protein A (NGFI-A) binding sequence (Weaver et al., 2004).

Strategies for discovery and validation of methylated and hydroxymethylated DNA biomarkers. Soon, other methylation studies of the ortholog human GR promoter (GR exon 1 promoter) emerged.

Chie Nishioka performed all experiments and wrote the article.Atsuya Nobumoto and Masayuki Tsuda provided technical support.Extended Student-led Research or Evaluation Project (ESREP). AML cells revealed that the levels of anti-apoptotic protein BCL2L12 were downregulated after CD82 depletion by specific short hairpin RNA (sh RNA).The numbering is relative to the start codon (ATG: 1), which is located 13 nucleotides downstream from the start of exon 2. Boxes represent known or putative canonical (solid-lined box) and non-canonical (broken-lined box) NGFI-A–binding sites according to Mc Gowan et al. region of the glucocorticoid receptor gene (NR3C1), and reported methylation changes in specific C—phosphate—G dinucleotides (i.e., Cp G sites) in relation to adverse life experiences (occurring in utero or early postnatal life) or conditions associated with adversity: borderline personality disorder (BPD), major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). The 47 Cp G sites in the exon 1 (sites 44–47) regions are numbered according to Figure 1, while 12 sites upstream or 5 sites downstream of the region are not numbered. doi: 10.1038/npp.2012.112 Pubmed Abstract | Pubmed Full Text | Cross Ref Full Text | Google Scholar Moser, D., Molitor, A., Kumsta, R., Tatschner, T., Riederer, P., and Meyer, J. The glucocorticoid receptor gene exon 1-F promoter is not methylated at the NGFI-A binding site in human hippocampus. In addition, sh RNA-mediated downregulation of BCL2L12 increased the levels of cleaved caspase-3 and suppressed proliferation of leukemia cells, impairing their engraftment in immunodeficient mice.Taken together, our results indicate that CD82 regulated BCL2L12 expression via STAT5A and AKT signaling and stimulated proliferation and engrafting of leukemia cells, suggesting that CD82 and BCL2L12 may be promising therapeutic targets in AML.
