TOP STORY

The Role of β Cell Glucagon-Like Peptide-1 Signaling in Glucose Regulation and Response to Diabetes Drugs
Glucagon-like peptide-1 (GLP-1), an insulinotropic gut peptide released after eating, is essential for normal glucose tolerance. To determine whether this effect is mediated directly by GLP-1 receptors (GLP1R) on islet β cells, researchers developed mice with β cell-specific knockdown of Glp1r. [Cell Metab]

DIABETES & PANCREATITIS

Chronological Analysis with Fluorescent Timer Reveals Unique Features of Newly Generated β Cells
While numerous studies have uncovered the molecular mechanisms regulating pancreas development, it remains to be clarified how β cells arise from progenitors, and how recently specified β cells are different from pre-existing β cells. Scientists developed a mouse model in which the insulin 1 promoter drives DsRed-E5 “Timer” fluorescence that shifts its spectrum over time. [Diabetes] Abstract

Efficacy of Gemcitabine Conjugated and miRNA-205 Complexed Micelles for Treatment of Advanced Pancreatic Cancer
Researchers designed self-assembling, gemcitabine conjugated cationic copolymers for co-delivery of a tumor suppressor miRNA-205 and evaluated their in vivo efficacy in a pancreatic cancer ectopic tumor model developed using gemcitabine resistant MIA PaCa-2^R cells. [Biomaterials] Abstract

TRB3 Is Involved in Free Fatty Acid-Induced INS-1-Derived Cell Apoptosis via the Protein Kinase C δ Pathway
Researchers outlined the role of tribbles homolog 3 (TRB3) in free fatty acids (FFAs)-induced INS-1 β cell apoptosis. TRB3 was promptly induced in INS-1 cells after stimulation by FFAs, and this was accompanied by enhanced INS-1 cell apoptosis. [PLoS One] Full Article

Puerarin Protects Pancreatic β-Cell Survival via PI3K/Akt Signaling Pathway
Scientists investigated the effect of puerarin on pancreatic β-cell survival and function. In cultured islets and MIN6 cells, puerarin protected β-cell from cobalt chloride-induced apoptosis, and restored the impaired capacity of glucose stimulated insulin secretion. [J Mol Endocrinol] Abstract

PANCREATIC CANCER

Gemcitabine and Chk1 Inhibition Potentiate EGFR-Directed Radioimmunotherapy against Pancreatic Ductal Adenocarcinoma
The combination of gemcitabine and Chk1 inhibitor PF-477736 with ¹⁷⁷Lu-anti-EGFR antibody was tolerated in mice. This triplet was effective in established tumors and prevented the recurrence of pancreatic ductal adenocarcinoma in four cell-line derived and one patient-derived xenograft models. [Clin Cancer Res] Abstract

PRIMA-1, a Mutant p53 Reactivator, Induces Apoptosis and Enhances Chemotherapeutic Cytotoxicity in Pancreatic Cancer Cell Lines
Scientists investigated the effects of p53 reactivation and induction of massive apoptosis (PRIMA-1) on cell viability, cell cycle and expression of p53-regulated proteins in PANC-1 and BxPC-3, and CAPAN-2 pancreatic cell lines. [Invest New Drugs] Abstract

Radiosensitization of Pancreatic Cancer Cells In Vitro and In Vivo through Poly (ADP-Ribose) Polymerase Inhibition with ABT-888
Scientists determined whether poly (ADP-ribose) polymerase-1/2 inhibition enhances radiation-induced cytotoxicity of pancreatic adenocarcinoma in vitro and in vivo, and the mechanism by which this occurs. [Transl Oncol] Full Article

Pancreatic Tumor Cell Secreted CCN1/Cyr61 Promotes Endothelial Cell Migration and Aberrant Neovascularization
In vitro and in vivo models show that pancreatic cancer cell generated unique microenvironments can underlie endothelial cell migration and tumor angiogenesis. [Sci Rep] Full Article

REVIEWS

Revealing Transcription Factors during Human Pancreatic β Cell Development
The authors present current knowledge of developing human β cell transcription factor expression, as compared to rodents. They also discuss recent studies employing transcription factor or epigenetic modulation to generate β cells. [Trends Endocrinol Metab] Abstract

Skin Deep: From Dermal Fibroblasts to Pancreatic Beta Cells
Researchers discuss a novel 3D platform for the generation of highly efficient human insulin-producing cells. [Immunol Res] Abstract
