objective:glioblastoma is an invasive tumor of the central nervous system. epigenetic therapy of cancer is potentially very useful in reversing some of cancer defects due to reversibility of epigenetic alterations. meg3 is a tumor suppressor long non-coding rna (lncrna) that expresses in the majority of normal tissues. methylation of the meg3 promoter region elicits a decrease in its expression...

results methylation in at least one gene was reported about 93.8%. the methylation of sfrp2 was reported in 39 out of the 48 subjects (81.2%) whereas methylation of mgmt was observed in 32 subjects (66.6%). conclusions the current study results showed that methylation of sfrp2 and mgmt play an important role in polyp formation. materials and methods forty eight tissue samples of polyp and adeno...

background: vhl (von hippel-lindau), runx-3 (runt-related transcription factor 3), e-cadherin (epithelial cadherin), p15 (ink4a, cyclin dependent kinase inhibitor), and p16 (ink4b) genes are essential in hematopoiesis. the aim of this study was to explore the correlation between gene expression and promoter methylation in cd34+ stem cells before and after differentiation to erythroid lineage. m...

Aberrant DNA methylation has been reported as an important phenotype in acute myeloid leukemia. However the clinical significance of methylation changes has not been clear yet. In this study methylation Specific Melting Curve Analysis (MS-MCA) and real time PCR was used to assess the CDKN2B promoter hyper-methylation and gene expression in 59 Iranian acute myeloid leukemia (AML) patients. The i...

Studies on earthworms using molecular markers are rare in Africa except a handful from South Africa. Reports on Libyodrilus violaceous,an earthworm found in West Africaare available including their metal tolerance and bioaccumulation capacity but their molecular characterization and ecotoxicology studies are scarce. In this study, triplicate L. violaceous specimens were collec...

Alcohol use disorder (AUD) has a complex, multifactorial etiology involving dysregulation across several brain regions and peripheral organs. Acute chronic alcohol consumption cause epigenetic modifications in these systems, which underlie changes gene expression subsequently, the emergence of pathophysiological phenotypes associated with AUD. One such mechanism is methylation, can occur on DNA...

conclusions no association was found between tfam promoter methylation and mes. the present study suggests that the tfam promoter methylation is not associated with risk of mes. objectives the aim of study was to investigate the possible association between promoter methylation of mitochondrial transcription factor a (tfam) and mes. patients and methods dna was extracted from peripheral blood o...

Epigenetic changes play an essential role in cancer pathogenesis. It has been established by next-generation sequencing that more than 50% of the human cancers carry mutations in mechanisms involved in the organization of the chromatin and epigenetic regulations. DNA methylation is among the most common epigenetic changes in leukemia. In contrast to DNA mutations which are passively inherited f...
