Retroperitoneal pararenal dedifferentiated liposarcoma with epithelioid/neuroendocrine features, somatostatin-positive.

open access: yesForum of Clinical Oncology, 2023
Liposarcomas are malignant mesenchymal neoplasms that, although derived from adipocytes, may dedifferentiate to other cell types. We present an exceedingly rare case of epithelioid/neuroendocrine dedifferentiation with somatostatin expression of a ...

Somatostatin and somatostatin receptors in retinal diseases [PDF]

open access: yesEuropean Journal of Endocrinology, 2000
Somatostatin is a small neuropeptide that is producedin the central nervous system, where it acts as aneurotransmitter. This neuropeptide also has animportant role in the neuroendocrine system as aninhibitor of hormone release, the most strikingexample of which is the inhibition of growth hormonerelease.

Reduced brain somatostatin in mood disorders: a common pathophysiological substrate and drug target?

open access: yesFrontiers in Pharmacology, 2013
Our knowledge of the pathophysiology of affect dysregulation has progressively increased, but the pharmacological treatments remain inadequate. Here, we summarize the current literature on deficits in somatostatin, an inhibitory modulatory neuropeptide ...

The therapeutic effect of the neuropeptide hormone somatostatin on Schistosoma mansoni caused liver fibrosis

open access: yesBMC Infectious Diseases, 2005
Background The neuropeptide somatostatin is one of the major regulatory peptides in the central nervous system and the digestive tract. Our recent work has delineated an association between fibrosis and low levels of endogenous somatostatin plasma levels

Effects of Aging on the Structure and Expression of NMDA Receptors of Somatostatin Expressing Neurons in the Mouse Hippocampus

open access: yesFrontiers in Aging Neuroscience, 2021
Changes in the physiology, neurochemistry and structure of neurons, particularly of their dendritic spines, are thought to be crucial players in age-related cognitive decline. One of the most studied brain structures affected by aging is the hippocampus,

Cellular mechanisms underlying central sensitization in a mouse model of chronic muscle pain

open access: yeseLife, 2022
Chronic pain disorders are often associated with negative emotions, including anxiety and depression. The central nucleus of the amygdala (CeA) has emerged as an integrative hub for nociceptive and affective components during central pain development ...

Somatostatin in the rat periventricular nucleus: sex differences and effect of gonadal steroids [PDF]

open access: yes, 2008
In the rat, the sexual dimorphism in growth hormone release is driven by sex steroids, and is suggested to result mainly from differences in somatostatin (SOM) release patterns from the median eminence.

The decrease in growth hormone (GH) response after repeated stimulation with GH-Releasing hormone is partly caused by an elevation of somatostatin tonus. [PDF]

open access: yes, 1996
Repeated injection of GHRH leads to a decrease in the GH response in normal subjects. Arginine (Arg) stimulates GH secretion by suppression of hypothalamic somatostatin.

Role of mTOR system and its relation with somatostatin and dopamine receptors on cell proliferation, hormone secretion and intracellular signalling in hepatocellular and cholangiocellular carcinomas. [PDF]

open access: yes, 2011
Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) are among the most lethal of human malignancies with s a very poor prognosis, with a

Recent Advances in the Modeling of Alzheimer’s Disease

open access: yesFrontiers in Neuroscience, 2022
Since 1995, more than 100 transgenic (Tg) mouse models of Alzheimer’s disease (AD) have been generated in which mutant amyloid precursor protein (APP) or APP/presenilin 1 (PS1) cDNA is overexpressed (1st generation models).
