SSTR is frequently expressed in thyroid cancer, with SSTR1 being the most commonly expressed in up to 88.8% of cases while SSTR2 is expressed in 44% of cases.[8, 12] We confirmed that all SSTR subtypes including SSTR4 are expressed in our panel of thyroid cancer cell lines both by Western blot and by immunofluorescence that is able to detect native receptor expression on the intact cell membranes (Fig 3). This evidence concerns the gene SSTR1 and thyroid gland carcinoma.
