STING1 and small cell lung carcinoma: Li et al. [166] identified three STING-related subtypes of SCLC from the RNA-seq dataset: STING-high, STING-median, and STING-low, among which, STING-high tumors were associated with increased immune infiltration and expression of immune checkpoint genes, while the STING-low type had higher activity of DDR and cell-cycle-checkpoint-related pathways.
