STING1 and neoplasm: This conclusion is strengthened by these two studies: First, the low expression of stimulator of interferon genes (STING) was positively correlated to signs of tumor invasion (Song et al., 2017); and second, UMUC14 cells with low mitogen-activated protein kinase phosphatase 1 (MKP-1) expression were more invasive than UMUC6 cells with high MKP-1 (Shimada et al., 2007).
