It has also been confirmed that 2′3′ cyclic GMP-AMP (cGAMP) moves through GJs formed between cancer cells and astrocytes, and accelerates the stimulator of interferon genes (STING) pathway in astrocytes, which finally promotes cytokine secretion such as tumor necrosis factor (TNF), which in turn assists cancer cell survival [3]. The gene discussed is STING1; the disease is cancer.
