About this study
Official title: The Effect of NF-кB Dependent Proinflammation on the Overexpression of Receptor of Advanced Glycation End Products (RAGE) and the Osteogenic Differentiation Defect in the Mesenchymal Stem Cell-isolated From Patients With Type 2 Diabetes
This study determines whether NF-кB dependent proinflammatory state found in type 2 diabetes yield to a higher RAGE activation in the mesenchymal stem cell, as well as the effects of the proinflammation on osteoblast differentiation impairment and cellular apoptosis in type 2 diabetic patients. This study will compare non-diabetic control subjects and type 2 diabetic patients with metformin monotherapy failure in the aspect of 1) serum markers for NF-кB dependent proinflammatory state and its intracellular signals, 2) osteogenic differentiation and apoptosis of the mesenchymal stem cells, and 3) serum AGE, RAGE and cellular RAGE activation.
Read the detailed description
This study aims to explore whether proinflammation in type 2 diabetes is an mechanism underlined higher RAGE activation and osteoblast differentiation defect demonstrated in the MSC of type 2 diabetes, as well as the effects of the proinflammation on cellular differentiation and apoptosis of the MSC. Type 2 diabetes was known to be in proinflammatory state due to NF-кB-dependent cytokine secretion (for example, TNF-α, IL1 and IL6), which in turn contribute to NF-кB upregulation. Because RAGE expression is partly regulated by NF-кB signal, the NF-кB upregulation in proinflammatory state observed in type 2 diabetes may entail RAGE overactivation in this population. Therefore, the proinflammatory state and its correlation to cellular NF-кB-dependent RAGE activation is noteworthy to be determined in the MSC of type 2 diabetes. Furthermore, the effect of proinflammation on differentiation potential and apoptosis of the MSC in type 2 diabetes remains to be elucidated.
