We measured the basal protein expression level of SSTR2 in human fibroblast cells (917 and WI38 cells), aggressive thyroid cancer cell lines (TPC, FTC236, and Hth7), and in various NET cell lines (medullary thyroid cancer: TT and MZ cells, pancreatic NE cancer: BON-1, and pulmonary carcinoid: H727) (Figure 1). This evidence concerns the gene SSTR2 and medullary thyroid gland carcinoma.
