Pancreatic islets isolated from β₂ adrenergic receptor knockout mice show reduced insulin secretion in response to nutrients - doi: 10.4025/actascibiolsci.v35i3.15842

Acta Scientiarum: Biological Sciences, 2013
Activation of β2 adrenergic receptors by catecholamine or catecholamine-mimetic substances may enhance insulin secretion. We herein investigated KCl- and nutrient-stimulated insulin secretion in pancreatic islets isolated from β2 knockout (β2KO) mice ...

Aging and Insulin Secretion

Experimental Biology and Medicine, 1995
Aging in mammals has often been associated with decreased insulin secretion and a subsequent deterioration in the ability to maintain glucose homeostasis. However, recent studies have demonstrated that factors such as disease, obesity, and physical activity more closely reflect diminished insulin secretion rather than aging per se. Thus, the purpose of

Rosuvastatin Treatment Affects Both Basal and Glucose-Induced Insulin Secretion in INS-1 832/13 Cells. [PDF]

PLoS ONE, 2016
Rosuvastatin is a member of the statin family. Like the other statins it is prescribed to lower cholesterol levels and thereby reduce the risk of cardiovascular events.

Diagnostic and referral pathways in patients with rare lipodystrophy and insulin-resistance syndromes: key milestones assessed from a national reference center

Orphanet Journal of Rare Diseases
Background Rare syndromes of lipodystrophy and insulin-resistance display heterogeneous clinical expressions. Their early recognition, diagnosis and management are required to avoid long-term complications.

Autoantibodies directed against insulin receptor during the course of Castleman disease: a new case reaffirming autoimmune hypoglycemia as a relapse warning signal

European Journal of Case Reports in Internal Medicine
This case study presents the case of a 54-year-old human immunodeficiency virus (HIV)-positive male who developed type B insulin resistance syndrome (TBIRS) in conjunction with a relapse of human herpesvirus 8 (HHV8)-positive multicentric Castleman ...

Insulin receptor signaling in the GnRH neuron plays a role in the abnormal GnRH pulsatility of obese female mice. [PDF]

PLoS ONE, 2015
Infertility associated with obesity is characterized by abnormal hormone release from reproductive tissues in the hypothalamus, pituitary, and ovary. These tissues maintain insulin sensitivity upon peripheral insulin resistance.

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Low, but Physiological, Concentration of GLP-1 Stimulates Insulin Secretion Independent of the cAMP-Dependent Protein Kinase Pathway

Journal of Pharmacological Sciences, 2008
Glucagon-like peptide-1 (GLP-1) induces pancreatic insulin secretion via the cAMP-dependent protein kinase (PKA) pathway. However, the GLP-1 concentration used in the previous in vitro experiments was far from the in vivo concentrations.
