Background: DNA Glycation damages DNA by inducing breaks of strands, mutations, and finally changes in gene expression, which is assumed as a main factor in pathogenesis of diabetes and its complications. Therefore, antiglycation agents have been focused recently for preventing and alleviating diabetes complications. According to the reported antidiabetic effects of Tamarix aphylla (T. aphylla) leaves extract, this study was aimed to determine the effect of T. aphylla on glucose-mediated DNA glycation for the first time.
