In addition, fatty acid receptor 2 (FFAR2) signaling antagonizes TLR2- and TLR3-induced lung cancer progression by inhibiting the process of cyclic adenosine monophosphate (cAMP)-adenylate-activated protein kinase (AMPK)-transforming growth factor β-activated kinase 1 (TAK1)-NF-κB activation (Kim et al., 2023). The gene discussed is FFAR2; the disease is lung cancer.
