Different Methylation Patterns of RUNX2, OSX, DLX5 and BSP in Osteoblastic Differentiation of Mesenchymal Stem Cells

OBJECTIVE Runt-related transcription factor 2 (RUNX2) and osterix (OSX) as two specific osteoblast transcription factors and distal-less homeobox 5 (DLX5) as a non-specific one are of paramount importance in regulating osteoblast related genes including osteocalcin, bone sialoprotein (BSP), osteopontin and collagen type Iα1. The present study sets out to investigate whether epigenetic regulatio...

epigenetic changes of runx2 and dlx5 genes in osteoblastic differentiation induced by zoledronic acid in mesenchymal stem cells

objective: zoledronic acid as a main treatment for osteoporosis has an important role in differentiation of mesenchymal stem cells. however, mechanism of osteoblastic differentiation induction by zoledronic acid is not well understood until now. in this research we evaluate zoledronic acid effect on methylation status of runx2 and dlx5 promoters. materials and methods: after isolation and expa...

Evaluation of Changes in Global DNA Methylation during Osteoblastic Differentiation of Mesenchymal Stem Cells: A Laboratory Study

Background and Objectives: Control processes in osteoblastic differentiation of mesenchymal stem cells are not yet fully understood. Epigenetic mechanisms, especially the methylation of CpG Islands in the promoter of genes, are considered as one of the most important control mechanisms in stem cell differentiation. In the process of differentiation, it is debated whether only the methylation of...

does dna methylation plays a critical role in osteoblastic differentiation of mesenchymal stem cells (mscs)?

ror2 promoter methylation change in osteoblastic differentiation of mesenchymal stem cells

objective: osteoblasts arise from multipotent mesenchymal stem cells (mscs) present in the bone marrow stroma and undergo further differentiation to osteocytes or bone cells. many factors such as proteins present in the wnt signaling pathway affect osteoblast differentiation. ror2 is an orphan tyrosine kinase receptor that acts as a co-receptor in the non-canonical wnt signaling pathway. howeve...

تاثیر داروی زولدرونیک اسید در بیان و متیلاسیون ژن BSP در طول تمایز استئوبلاستیک سلولهای بنیادی مزانشیمی

Background and Aim: Bone sialoprotein (BSP) is a specific marker of osteoblastic differentiation. In this research, the effect of Zoledronic Acid on BSP expression and methylation status during osteoblastic differentiation of mesenchymal stem cells (MSCs) was evaluated. Materials and Methods: In this experimental study, MSCs were isolated from human bone marrow. For osteogenic differentiation,...
