Anticancer Effects of miR-124 Delivered by BM-MSC Derived Exosomes on Cell Proliferation, Epithelial Mesenchymal Transition, and Chemotherapy Sensitivity of Pancreatic Cancer Cells

miR-124 or EZH2 was overexpressed in AsPC-1 and PANC1 cells. Then, the effects on cell viability, apoptosis, invasion, migration and epithelial mesenchymal transition were evaluated. The roles of miR-124 on the expression and function of EZH2 in pancreatic tumors were determined by dual luciferase reporter assay. Subsequently, miR-124 was transfected to bone marrow mesenchymal stromal cells (BM-MSCs), and the BM-MSCs derived exosomes were isolated and co-cultured with AsPC-1 and PANC1 cells, or injected into pancreatic cancer tumor-bearing mice.

Aberrant Methylation Underlies Insulin Gene Expression in Human Insulinoma

Scientists found a consistent, abnormal methylation pattern in insulinomas. They found that abnormal insulin (INS) promoter methylation and altered transcription factor expression created alternative drivers of INS expression, replacing canonical PDX1-driven beta cell specification with a pathological, looping, distal enhancer-based form of transcriptional regulation.

Non-Coding RNA Biomarkers in Pancreatic Ductal Adenocarcinoma

The authors focus on three types of well-established ncRNAs — microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs) — and discuss their potential as diagnostic, prognostic and predictive biomarkers in pancreatic ductal adenocarcinoma.

Paracrine Regulation of Somatostatin Secretion by Insulin and Glucagon in Mouse Pancreatic Islets

Researchers demonstrated that somatostatin and glucagon secretion were linked in a reciprocal feedback cycle with somatostatin inhibiting glucagon secretion at low and high glucose levels, and glucagon stimulating somatostatin secretion via the glucagon and GLP-1 receptors.

Co-impairment of Autonomic and Glucagon Responses to Insulin-Induced Hypoglycemia in Dogs with Naturally-Occurring Insulin-Dependent Diabetes Mellitus

Plasma glucagon responses during hyperinsulinemic-hypoglycemic clamps (40 mg/dL) were assessed in dogs with spontaneous diabetes (n=13) and healthy non-diabetic dogs (n=6). Plasma C-peptide responses to intravenous glucagon were measured to assess endogenous insulin secretion. Plasma pancreatic polypeptide, epinephrine and norepinephrine were measured as indices of parasympathetic and sympathoadrenal autonomic responses to insulin-induced hypoglycemia.

Pancreas-Specific Deletion of Protein Kinase D Attenuates Inflammation, Necrosis, and Severity of Acute Pancreatitis

Investigators generated a mouse model with pancreas-specific deletion of PKD3, the predominant PKD isoform in mouse pancreatic acinar cells, by crossing Pkd3flox/flox mice with Pdx1-Cre transgenic mice which express Cre recombinase under the control of the mouse Pdx1 promoter.

Neurotensin Receptor 1 Signaling Promotes Pancreatic Cancer Progression

Investigators used sublines to screen molecular targets for the treatment of pancreatic cancer. Among the genes with increased expression levels in the sublines, they focused on those encoding cell surface receptors that may be involved in the interactions between cancer cells and the tumor microenvironment.
