Abstract

Background: DNA glycation, a process where Glc non-enzymatically binds to DNA, is implicated in various detrimental effects, including strand breaks, mutations, and altered gene expression. This damage is considered a significant contributor to the pathogenesis of diabetes mellitus and its associated complications. Consequently, there has been increasing interest in identifying antiglycation agents as a strategy for preventing and mitigating these complications. Prior research has indicated that extracts from Tamarix aphylla (T. aphylla) leaves possess antidiabetic properties. Therefore, this study aimed to investigate, for the first time, the impact of T. aphylla extract on Glc-mediated DNA glycation.
Methods: DNA samples were incubated with Glc over a four-week period. Subsequently, the modulatory effects of T. aphylla on Glc-induced DNA structural alterations were investigated employing a range of analytical techniques. These methodologies encompassed ultraviolet-visible (UV-Vis) spectroscopy, fluorescence spectroscopy, circular dichroism (CD) spectroscopy, and agarose gel electrophoresis.
Results: The results obtained from UV–Vis and fluorescence spectroscopy demonstrated that T. aphylla extract led to a reduction in the formation of DNA-advanced glycation end products (AGEs). Furthermore, CD spectroscopy and agarose gel electrophoresis analyses indicated that the structural alterations of glycated DNA were diminished in the presence of T. aphylla extract.
Conclusion: Based on the evidence presented, T. aphylla demonstrates protective properties against DNA glycation. Consequently, pending further rigorous investigation, it may represent a potentially valuable therapeutic agent for mitigating the detrimental consequences of glycation, particularly in environments characterized by elevated Glc concentrations and hyperglycemic states.
