An RNA-seq dataset containing 675 commonly used human cancer cell lines obtained from Array Express (Klijn et al., 2015, ArrayExpress experiment E-MATB-2706), 622 of which contained data for TAAR1 RNA expression, revealed that TAAR1 RNA is most highly expressed in the pancreatic somatostatinoma cell line QGP-1, lung carcinoid tumor cell line UMC-11, and the lung adenocarcinoma cell line VMRC-LCD. Here, TAAR1 is linked to pancreatic somatostatinoma.
