Clinical Importance of Somatostatin Receptor 2 (SSTR2) and Somatostatin Receptor 5 (SSTR5) Expression in Thyrotropin-Producing Pituitary Adenoma (TSHoma) [PDF]

Medical Science Monitor, 2017
BACKGROUND Thyrotropin-secreting pituitary adenomas (TSHomas) are a rare cause of hyperthyroidism. Somatostatin analogs have proved to be effective for inhibiting pituitary hormones secretion, working via interactions with somatostatin receptors (SSTRs). Moreover, antiproliferative activity of somatostatin analog is now demonstrated in several studies.

Advances in Parahydrogen‐Induced Polarization for Nuclear Magnetic Resonance of Peptides, Proteins, and Biopolymers

ChemistryEurope, EarlyView.
Hyperpolarization by parahydrogen‐induced polarization enhances the sensitivity of nuclear magnetic resonance spectroscopy of amino acids, peptides, mini‐proteins, and biopolymers using nonnatural amino acids with unsaturated side chains up to three orders of magnitude.

A novel PTEN variant causing hemimegalencephaly and focal nodular heterotopias in the developing human brain

Epilepsia, EarlyView.
Abstract Brain development and subsequent brain function are highly sensitive to genetic mutations, which can result in severe neurodevelopmental malformations. Alterations in PTEN signaling cause a spectrum of developmental malformations and neurological diseases including epilepsy.

New cross-roads for second line medical therapy in acromegaly [PDF]

Archives of the Balkan Medical Union, 2018
Acromegaly is a complex disorder caused by growth hormone excess mostly due to a pituitary adenoma. Surgery represents the first option but rate of long time success is almost 50% thus the patients need other therapies.

Gut‐microbiota‐brain Axis and post‐traumatic epilepsy

Epilepsia Open, EarlyView.
Abstract There has been growing evidence that perturbations in gut‐microbiota‐brain axis (GMBA) are involved in mechanisms of chronic sequelae of traumatic brain injury (TBI). This review discusses the connection between GMBA and post‐traumatic epilepsy (PTE), the latter being a common outcome of TBI.

The expression and the nuclear activity of the caretaker gene ku86 are modulated by somatostatin

European Journal of Histochemistry, 2009
Somatostatin is a peptide hormone that exerts antisecretory and antiproliferative activities on some human tumors. The Ku70/86 heterodimer acts as regulatory subunit of the DNA dependent protein kinase and its DNA binding activity mediates DNA double ...

Survival outcomes and prognostic factors of gastric carcinoma with neuroendocrine differentiation

International Journal of Cancer, EarlyView.
What's New? Although gastric carcinoma with neuroendocrine differentiation (GCNED) is associated with more aggressive features than conventional GC, its prognosis and survival remain poorly defined. To better understand survival patterns, the authors of the present study examined clinicopathological and prognostic features of GCNED patients following ...

Cholecystokinin and Somatostatin Negatively Affect Growth of the Somatostatin-RIN-14B Cells

International Journal of Endocrinology, 2009
With the exclusive presence of the pancreatic CCK-2 receptors on the pancreatic delta cells of six different species, this study was undertaken to determine the role of cholecystokinin and gastrin on growth of these somatostatin (SS) cells.

Regulation of somatostatin expression by vitamin D3 and valproic acid in human adipose-derived mesenchymal stem cells

Stem Cell Research & Therapy, 2019
Background Adipose-derived mesenchymal stem cells (ADMSC) are non-haematopoietic, fibroblast-like multipotent progenitor cells. They have the potential for trilineage (adipocyte, chondrocyte and osteocyte) differentiation as well as differentiation into ...

Clinical Implications of Ki‐67 Index, Grade and Hormonal Changes in Pancreatic Neuroendocrine Tumors: Insights Into Tumor Heterogeneity Based on Primary and Secondary Lesions

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background Pancreatic neuroendocrine tumors (PanNETs) show heterogeneity, including temporal shifts in proliferation and hormone production; however, their clinical implications remain uncertain. Methods This retrospective study included 114 patients with metastatic or recurrent PanNETs at Kyushu University Hospital.
