Targeting 8-oxoguanine DNA glycosylase-1 (OGG1) as a therapeutic strategy in inflammatory-related diseases

OBJECTIVE: Inflammatory diseases are influenced by oxidative stress. Oxidatively damaged 8-oxoG in DNA is linked to inflammation. The enzyme OGG1 is responsible for repairing the damaged base in the DNA which is linked to pro-inflammatory signaling and severe inflammation. This study aims to explore the potential of targeting OGG1 as a therapeutic strategy in inflammatory disease conditions.

METHODS: A comprehensive search and review of literature were conducted using appropriate scientific databases such as Google Scholar, Scopus, PubMed, Web of Science, and other references to obtain relevant information that suited the title and content of this article.

RESULTS: Compelling pieces of evidence from many previous studies have shown the crucial role of the OGG1/8oxoG pathway in inflammatory disease conditions, leading to severe inflammatory response and death. Therefore, based on these pieces of evidence, targeting this enzyme (OGG1) using specific pharmacological inhibitors or interventions might lead to downregulation and amelioration of severe inflammation to reduce the morbimortality related to several disease conditions.

CONCLUSION: This review highlighted the molecular mechanism of OGG1 activity via the 8-oxo/OGG1 pathway and its role in inflammation and inflammatory disease conditions. Due to the paucity of studies involving OGG1in inflammatory infectious diseases, further research projects are needed to explore the therapeutic potential of various OGG1 inhibitors to serve as novel therapeutic strategies in infectious inflammatory diseases of medical importance in developing countries such as malaria, meningitis, tuberculosis among others.
