26474434 Data showed that the distribution of somatostatin receptor (SSTR) subtypes among the 199 pancreatic neuroendocrine tumors (PNETs) was: SSTR2 (54.8%), SSTR1 (53.3%), SSTR4 (51.8%), SSTR5 (33.7%), and SSTR3 (28.6%).
25962406 An immunohistochemical investigation of the expression of somatostatin receptor subtypes
25925002 SSTR2 and SSTR5 protein levels were induced as compared to any agent alone.
25854304 This is the first evidence indicating that sst5TMD4 is expressed in human medullary thyroid carcinoma cells, where it associates with more aggressive behavior, suggesting that sst5TMD4 might play a functionally relevant role.
25808161 Data indicate that somatostatin receptor scintigraphy (SRS) and immunohistochemical results for somatostatin and dopamine receptors sstr2, sstr3, sstr5 and D2R were compared in neuroendocrine neoplasms tissues.
25765179 Somatostatin receptors were expressed in a high proportion of merkel cell carcinomas, although expression was heterogeneous between tumours and was not associated with disease severity.
25637790 A truncated sst5-variant (sst5TMD4) can influence the secretory response of somatotropinomas to somatostatin analogues-therapy.
25008035 SSTR5 was the predominantly expressed receptor subtype in the cytoplasm of all GH-secreting adenomas tested, regardless of whether they came from octreotide-naive, octreotide-responsive, or octreotide-resistant patients. SSTR5 mRNA predominance was significant only in octreotide treated patients. Its expression was not correlated with baseline or post-octreotide GH or IGF-1 levels or tumor volume.
24967740 SSTR 5 was shown to be the main receptor subtype in the analysed differentiated or anaplastic thyroid malignancies, whereas SSTR 2 was found only in a small percentage.
24634938 Tumor cells in the tissue samples of the patients diagnosed with advanced-stage hepatocellular carcinoma expressed a high proportion of SSTR1 and SSTR5.
24465589 SSTR5 protein is overexpressed in poorly differentiated thyroid cancer and may be involved in the lack of response to somatostatin analogue treatment.
24189142 Whereas sst2 receptors might play a primary role in the differentiation and regulation of TSH, LH, and FSH cells, sst5 receptors appear to be mainly involved in GH regulation from birth onward

21419811 demonstrate that cells transfected with SSTR1 or SSTR1/5 negatively regulates EGF mediated effects attributed to the inhibition of EGFR phosphorylation.
21383526 differential gene expression profiles revealed more abundant mRNA expression in ectopic ACTH syndrome than in Cushing disease of SSTR-5
21249361 SSTR5 P335L is a hypofunctional protein with a potentially harmful effect on function, as well as potential latent effect, and therefore it could affect the clinical response to somatostatin analog therapy for patients with pancreatic cancer.
21238583 The heterodimerization of somatostatin receptor-5 not only indicate the receptor's specificity of interaction but also provide new insight to understand the molecular mechanism in regulation of signaling pathway in receptor specific manner.
21190959 These data indicate that the activation and/or overexpression of SST receptors along with the inhibition of EGFR will serve as an important therapeutic approach in the treatment of ErbB-positive tumors.

19070659 To the best of our knowledge, this is the first report describing crosstalk/interactions between SSTRs and ErbBs.
18936524 Immunohistochemistry stufy of SSTR5 in prostate tissue from patients with bladder outlet obstruction showed that close to 90% of secretory cells showed a weak positivity in the cytoplasm.
18653781 Data show that human somatostatin receptors (SSTR)2 and SSTR5 heterodimerize, and that selective activation of SSTR2 and not SSTR5, or their costimulation, modulates the association.
18066572 The majority of all benign, premalignant and malignant laryngeal specimens expressed moderate to high levels of expression of SSTR5.
17159301 The expression of SSTR5 in TSHoma may be a useful marker for predicting the outcome of octreotide therapy.

15914528 role for SSTR5 t-461c and c1004t alleles in influencing GH and IGF-I levels in patients with acromegaly, whereas SSTR2 and SSTR5 variants seem to have a minor role in determining the responsiveness to somatostatin analogs
15247250 activation of hSSTR5 but not hSSTR1 is necessary for heterodimeric assembly
15118275 The degree (or level) of sst2 and sst5 expression is critical for the ultimate GH response of somatotropinomas to endogenous SRIF tone and exogenous SRIF analogue therapy.
