cGAS-STING at the crossroads in cancer therapy

Area of Science:

• Immunology
• Molecular Biology
• Oncology

Background:

• DNA, both exogenous and endogenous, triggers immune responses via pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs).
• The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is a conserved signaling cascade activated by DNA, leading to inflammatory responses.
• Dysregulation of the cGAS-STING pathway is implicated in the pathogenesis and progression of neoplastic diseases.

Purpose of the Study:

• To review the molecular mechanisms of cGAS-STING pathway deregulation in cancer.
• To highlight the dual role of cGAS-STING signaling in inhibiting and promoting tumor development.
• To discuss the challenges and potential of cGAS-STING agonists in cancer therapy.

Main Methods:

• Literature review of molecular mechanisms.
• Analysis of cGAS-STING pathway's role in tumorigenesis.
• Evaluation of therapeutic strategies involving cGAS-STING modulation.

Main Results:

• The cGAS-STING pathway exhibits complex roles, acting as both a tumor suppressor and a tumor promoter depending on the context.
• Deregulation of cGAS-STING signaling can initiate and drive tumor development.
• Modulating the cGAS-STING pathway presents therapeutic opportunities but also significant challenges.

Conclusions:

• Understanding the intricate molecular mechanisms of cGAS-STING deregulation is essential for its effective targeting in cancer.
• Targeting the cGAS-STING pathway holds significant promise for innovative cancer therapies.
• Further research is needed to overcome challenges associated with cGAS-STING agonists for optimal therapeutic outcomes.
