P-31: Effect of Cryptop Vitrification on DNAMethylation Pattern of Oct4 and Mest Genes inMurine Preimplantation Embryos
Background: Because of the protection of surplus embryos, Cryopreservation is usually used in ART. It is not clear, the vitrified-warmed embryos that have normal morphology, be normal in genetic level, too. DNA methylation of gene regulatory regions can causes inhibition of gene expression. We study effect of vitrification method of cryopreservation on DNA methylation and gene expression level ...
متن کاملP-70: Evidence for Differential Gene Expression of A Major EpigeneticModifier Enzyme, de novo DNA Methyltransferase 3b, through Vitrification of Mouse Ovary Tissue
Background: Ovarian tissue cryopreservation is a feasible method to preserve female reproductive potential, especially in young patients with cancer or in women at risk of premature ovarian failure. Vitrification has recently emerged as a new trend for biological specimen preservation. On the other hand, gene expression that changes during vitrification can influence oocyte maturation and need ...
متن کاملEffects of 5-aza-2ˈ-deoxycytidine and Valproic Acid on Epigenetic-modifying DNMT1 Gene Expression, Apoptosis Induction and Cell Viability in Hepatocellular Carcinoma WCH-17 cell line
Background: DNA molecule of the eukaryotic cells is found in the form of a nucleoprotein complex named chromatin. Two epigenetic modifications are critical for transcriptional control of genes, including acetylation and DNA methylation. Hypermethylation of tumor suppressor genes is catalyzed by various DNA methyltransferase enzymes (DNMTs), including DNMT1, DNMT2, and DNMT3. The most well chara...
متن کاملGene Expression and Promoter Methylation Status of VHL, Runx-3, E-cadherin, P15 and P16 Genes During EPO-Mediated Erythroid Differentiation of CD34+ Hematopoietic Stem Cells
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...
متن کاملConstruction of an Eukaryotic Expression Vector Encoding Herpes Simplex Virus Type 2 Glycoprotein D and In Vitro Expression of the Desired Protein
To construct of an eukaryotic expression vector encoding herpes simplex virus type 2 (HSV-2) glycoprotein D (gD2), an Iranian isolate of HSV-2 was propagated in HeLa cell line and its DNA was extracted and used as template in polymerase chain reactions (PCR), to amplify gD2 gene. Primers were designed and the restriction enzyme sites for EcoRI and XhoI were considered at their 5′ ends respectiv...
