TOP STORY
High Insulin Levels Tied to Obesity Pathway
Researchers found that giving mice high levels of insulin, which is typically done to counter the effects of diabetes or insulin resistance in type 2 diabetes, also fosters processes that lead to obesity.

DIABETES & PANCREATITIS

SORCS1 Is Necessary for Normal Insulin Secretory Granule Biogenesis in Metabolically Stressed β-Cells
The luminal domain of SORCS1, when expressed in a β-cell line, acted as a dominant-negative, leading to secretory granules (SG) and insulin deficiency. Using syncollin-dsRed5TIMER adenovirus, researchers found that the loss of Sorcs1 function greatly impairs the rapid replenishment of SG following secretagogue challenge.

Chronic Pancreatitis and Pancreatic Cancer Demonstrate Active Epithelial-Mesenchymal Transition Profile, Regulated by miR-217-SIRT1 Pathway
Since recent evidence indicates microRNAs (miRNAs) may be involved in epithelial-mesenchymal transition (EMT), researchers set out to reveal the miRNA which might regulate the EMT in chronic pancreatitis and pancreatic cancer and its potential mechanism. [Cancer Lett] Full Article

Na+ Current Properties in Islet α- and β-Cells Reflect Cell-Specific Scn3a and Scn9a Expression
Single-cell PCR analyses showed that both α- and β-cells have Nav1.3 (Scn3) and Nav1.7 (Scn9a) α-subunits, but their relative proportions differ: β-cells principally express Nav1.7 and α-cells Nav1.3. [J Physiol] Abstract

Co-Culture with Mature Islet Cells Augments the Differentiation of Insulin-Producing Cells from Pluripotent Stem Cells
Researchers describe a method to efficiently differentiate pluripotent stem cells (PSCs) into insulin-producing cells by co-culturing mature islets with directed-differentiated pancreatic endoderm cells from mouse and human PSCs. [Stem Cell Rev] Abstract

PANCREATIC CANCER

Thiol-ene Hydrogels as Desmoplasia-Mimetic Matrices for Modeling Pancreatic Cancer Cell Growth, Invasion, and Drug Resistance
Researchers report a photo-curable and bio-orthogonal thiol-ene hydrogel platform for studying the growth, morphogenesis, drug resistance, and cancer stem cell marker expression in pancreatic ductal adenocarcinoma cells cultured in 3D. [Biomaterials] Abstract

KRAS Mutational Subtype and Copy Number Predict In Vitro Response of Human Pancreatic Cancer Cell Lines to MEK Inhibition
Researchers studied the molecular mechanism regulating sensitivity to MEK inhibition in pancreatic cancer cell lines. [Br J Cancer] Full Article

Down-Regulation of 5-HT1B and 5-HT1D Receptors Inhibits Proliferation, Clonogenicity and Invasion of Human Pancreatic Cancer Cells
Researchers found that knockdown of serotonin (5-HT)1B and 5-HT1D receptors expression, using specific small interfering RNA, induced significant inhibition of proliferation and clonogenicity of pancreatic cancer cells. [PLoS One] Full Article

ANO1 (TMEM16A) in Pancreatic Ductal Adenocarcinoma (PDAC)
Scientists aimed to establish the significance of ANO1 in PDAC behavior and demarcate its roles in PDAC from those of the volume-regulated anion channel. [Pflugers Arch] Full Article
