عنوان انگلیسی Comparison of Epigenetic Modifier Genes in Bovine Adipose Tissue-Derived Stem Cell Based Embryos, as Donors, with In Vitro and Parthenogenesis Embryos
چکیده انگلیسی مقاله Objective
Regarding that undifferentiated mesenchymal stem cells, as donor cells, require less epigenetic reprogramming, possibility of using bovine adipose tissue-derived stem cells (BASCs) with low level of DNMTs and HDACs expression was evaluated.
Materials and Methods
In this experimental study, we examined gene expression of epigenetic modifiers including DNA methyltransferases (DNMT1, DNMT3A and DNMT3B) and histone deacetylases (HDAC1-3), as well as protein levels of histone H3 acetylation at lysine 9 (H3K9ac) and POU5F1 (also known as OCT4) at two stages of preimplantation development among in vitro fertilization (IVF), parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT) groups.
Results
The results revealed that developmental competence of IVF embryos was higher than SCNT embryos (P < 0.05). In the PA and SCNT groups, DNMT1, HDAC2 and HDAC3 mRNA were overexpressed (P < 0.05), and proteins levels of H3K9ac and POU5F1 were reduced at 6-8 cells and blastocyst stages compared to IVF (P < 0.05). The mRNA expression of DNMT1 an
