Stimulator of interferon response cGAMP interactor 1 mRNA (STING1 mRNA)

STING1 mRNA is the transcript of the Stimulator of Interferon Response cGAMP Interactor 1 gene, which encodes the STING protein, a pivotal regulator of the innate immune system [1]. The STING protein functions as a sensor for cytosolic DNA, typically originating from pathogens or damaged tumor cells, and its activation leads to the production of Type I interferons and pro-inflammatory cytokines [2]. In therapeutic development, STING1 mRNA is utilized in two distinct ways: as a therapeutic agent (mRNA therapy) where synthetic mRNA is delivered to tumors to induce STING expression and stimulate anti-tumor immunity, or as a target for degradation (RNA interference or antisense therapy) to treat autoinflammatory diseases like STING-associated vasculopathy with onset in infancy (SAVI) [3, 4]. This dual approach allows for the precise modulation of the cGAS-STING pathway, which is often dysregulated in both malignancy and chronic inflammation [1, 2]. Current research focuses on optimizing delivery systems, such as lipid nanoparticles, to enhance the stability and tissue-specific targeting of these RNA-based molecules [3]. While small molecule agonists have faced challenges regarding systemic toxicity and delivery, mRNA-based approaches offer a potentially more controlled and localized method of pathway activation. Furthermore, the use of antisense oligonucleotides targeting STING1 mRNA provides a promising strategy for managing interferonopathies where the pathway is constitutively active [4].
