Abstract
Enhancers are regulatory DNA elements that play a crucial role in controlling gene expression in specific cell types, including neurons. Enhancer activity is tightly regulated and involves the recruitment of various proteins and enzymes to facilitate the opening of chromatin and the activation of target genes. Given the importance of enhancers in neuronal function, the presence of single-strand DNA breaks (SSBs) in these regions raises intriguing questions about their potential impact on gene regulation and neuronal activity. Single-strand DNA breaks (SSBs) have been identified as important lesions in the genome, with the potential to influence gene expression and genomic stability. By understanding the role of SSB repair and human mono-functional Thymine-DNA glycosylase (TDG) catalyzed futile excision of regular bases in enhancer regions, we may gain insights into the molecular mechanisms underlying neurological disorders and potentially identify new therapeutic targets for intervention.
