Genome Editing of Lineage Determinants in Human Pluripotent Stem Cells Reveals Mechanisms of Pancreatic Development and Diabetes
Scientists used TALEN and CRISPR/Cas-mediated gene editing and human pluripotent stem cells-directed differentiation for a systematic analysis of the roles of eight pancreatic transcription factors (PDX1, RFX6, PTF1A, GLIS3, MNX1, NGN3, HES1, and ARX). [Cell Stem Cell] Abstract | Graphical Abstract

Age-Dependent Pancreatic Gene Regulation Reveals Mechanisms Governing Human β Cell Function
The authors described a multimodal strategy for isolating pancreatic endocrine and exocrine cells from children and adults to identify age-dependent gene expression and chromatin changes on a genomic scale. [Cell Metab] Abstract | Press Release | Graphical Abstract

Extranuclear Actions of the Androgen Receptor Enhance Glucose-Stimulated Insulin Secretion in the Male
Investigators showed that male mice lacking androgen receptor in β cells exhibit decreased glucose-stimulated insulin secretion, leading to glucose intolerance. [Cell Metab] Abstract | Graphical Abstract

Transforming Growth Factor-β Limits Secretion of Lumican by Activated Stellate Cells within Primary Pancreatic Adenocarcinoma Tumors
Lumican expression in pancreatic ductal adenocarcinoma from 27 patients was determined by IHC and quantitatively analyzed for co-localization with pancreatic stellate cells (PSC). In vitro studies examined the molecular mechanisms of lumican transcription and secretion from PSC, and cell adhesion and migration assays examined the effect of lumican on PSC in a collagen-rich environment. [Clin Cancer Res] Abstract

Sensitization to and Challenge with Gliadin Induce Pancreatitis and Extrapancreatic Inflammation in HLA-DQ8 Mice: An Animal Model of Type 1 Autoimmune Pancreatitis
Scientists aimed to establish a pathogenetic mechanism of pancreatitis in celiac disease and IgG4-related disease using gluten-sensitive human leukocyte antigen (HLA)-DQ8 transgenic mice. [Gut Liver]

Peptide Binding Glucose Regulated Protein 78 Improves Type 1 Diabetes by Preventing Pancreatic β Cell Apoptosis
The authors examined the effects of peptide binding cell surface GRP78 to reduce the deleterious effects of diabetes induced by streptozotocin. They demonstrated the ability of the peptide to protect the pancreatic β cells from apoptosis. [Exp Clin Endocrinol Diabetes] Abstract


Abrogating Cholesterol Esterification Suppresses Growth and Metastasis of Pancreatic Cancer
The authors report a significant role of cholesterol metabolism in cancer metastasis. By using label-free Raman spectromicroscopy, they found an aberrant accumulation of cholesteryl ester in human pancreatic cancer specimens and cell lines, mediated by acyl-CoA cholesterol acyltransferase-1 enzyme. [Oncogene] Full Article

Micelle Mixtures for Coadministration of Gemcitabine and GDC-0449 to Treat Pancreatic Cancer
Investigators report the use of methoxy poly(ethylene glycol)-block-poly(2-methyl-2-carboxyl-propylene carbonate)-graft-dodecanol copolymer for conjugating gemcitabine and encapsulating a Hedgehog inhibitor, vismodegib, into its hydrophobic core for treating pancreatic ductal adenocarcinoma. [Mol Pharm] Abstract

Low Dose Monoethyl Phthalate (MEP) Exposure Triggers Proliferation by Activating PDX-1 at 1.1B4 Human Pancreatic Beta Cells
Researchers studied the effects of MEP, the metabolite of diethyl phthalate, exposure on 1.1B4 human pancreatic beta cells at low doses. They showed that MEP treatment induced proliferation in 1.1B4 cells. [Food Chem Toxicol] Abstract

Transcriptome Analysis of Piperlongumine-Treated Human Pancreatic Cancer Cells Reveals Involvement of Oxidative Stress and Endoplasmic Reticulum Stress Pathways
Researchers aimed to identify the underlying molecular mechanisms for piperlongumine (PL) anticancer effects on human pancreatic cancer cells. RNA sequencing was used to identify the effects of PL on the transcriptome of MIA PaCa-2 human pancreatic cancer cells. [J Med Food] Abstract

Weekend-Free Culture hPSCs with mTeSR™1 or TeSR™-E8™
Replicative Capacity of β-Cells and Type 1 Diabetes
The reviewers highlight features of the β-cell, including it being part of a pancreatic islet, a mini-organ that is highly vascularized and highly innervated, and efforts to promote β-cell proliferation. [J Autoimmun] Abstract
