TOP STORY

CFTR and Anoctamin 1 (ANO1) Contribute to cAMP Amplified Exocytosis and Insulin Secretion in Human and Murine Pancreatic Beta-Cells
Experiments were performed on islets and single beta-cells from human donors and NMRI-mice. Detection of cystic fibrosis transmembrane conductance regulator (CFTR) was investigated using PCR and confocal microscopy. Effects on insulin secretion were measured with radioimmunoassay.

DIABETES & PANCREATITIS

Imatinib Mesylate Stimulates Low-Density Lipoprotein Receptor-Related Protein 1-Mediated ERK Phosphorylation in Insulin Producing Cells
Scientists studied LRP1 function in beta-cells and to what extent imatinib modulates LRP1 activity. LRP1 and c-Abl gene knockdown was performed by RNAi using rat INS-1 832/13 and human EndoC1-bH1 cells. [Clin Sci] Abstract

Maternal Inheritance of an Inactive Type III Deiodinase Gene Allele Affects Mouse Pancreatic β-Cells and Disrupts Glucose Homeostasis
Researchers used heterozygous D3KO animals to study the allelic expression pattern of Dio3 in pancreatic β-cells and the metabolic phenotype resulting from its inactivation. [Endocrinology] Abstract

Quantitative Proteomics Reveals the Link between Minichromosome Maintenance Complex and Glucose-Induced Proliferation of Rat Pancreatic INS-1E β-Cells
Scientists applied the SILAC strategy to INS-1E cells cultivated with medium or high glucose concentrations for 24 hours, and they targeted nuclear proteins that have a central role in proliferation-related mechanisms. [J Proteomics] Abstract

Transplantation of Betacellulin-Transduced Islets Improves Glucose Intolerance in Diabetic Mice
Researchers transduced islets with adenoviruses expressing betacellulin, an epidermal growth factor receptor ligand, which promotes β-cell growth and differentiation, and transplanted these islets under the renal capsule of streptozotocin-induced diabetic mice. [Exp Mol Med] Full Article

PANCREATIC CANCER

Targeting the Warburg Effect with a Novel Glucose Transporter Inhibitor to Overcome Gemcitabine Resistance in Pancreatic Cancer Cells
The effects of gemcitabine and/or CG-5 on viability, survival, glucose uptake, and DNA damage were evaluated in gemcitabine-sensitive and -resistant pancreatic cancer cell lines. [Carcinogenesis] Abstract

Profiling and Targeting of Cellular Bioenergetics: Inhibition of Pancreatic Cancer Cell Proliferation
Scientists mapped the two intrinsic cellular bioenergetic parameters, oxygen consumption rate and proton production rate in six different pancreatic cancer cell lines and determined their differential sensitivity to mitochondrial and glycolytic inhibitors. [Br J Cancer] Abstract

Gemcitabine Diphosphate Choline Is a Major Metabolite Linked to the Kennedy Pathway in Pancreatic Cancer Models In Vivo
Researchers used a mouse model of pancreatic ductal adenocarcinoma: KRAS^G12D; p53^R172H; pdx-Cre that recapitulates the human disease to study gemcitabine intra-tumoral metabolism. [Br J Cancer] Full Article

XMD8-92 Inhibits Pancreatic Tumor Xenograft Growth via DCLK1-Dependent Mechanism
Scientists showed that XMD8-92 inhibits AsPC-1 cancer cell proliferation and tumor xenograft growth. XMD8-92 treated tumors demonstrated significant downregulation of doublecortin-like kinase1 (DCLK1) and several of its downstream targets via upregulation of tumor suppressor miRNAs. [Cancer Lett] Abstract

Pancreatic Cancer Cell Glycosylation Regulates Cell Adhesion and Invasion through the Modulation of α2β1 Integrin and E-Cadherin Function
Scientists addressed the role of a glycosylation pattern in the functional properties of two glycoproteins involved in the processes of cancer cell invasion and migration, α2β1 integrin, the main receptor for type 1 collagen, and E-cadherin, responsible for cell-cell contacts and whose deregulation determines cell invasive capabilities.

REVIEWS

Use of Herbal Medicines and Natural Products: An Alternative Approach to Overcoming the Apoptotic Resistance of Pancreatic Cancer
The authors give a critical appraisal of the use of herbal medicines or natural products alone and in combination with anti-cancer drugs. They also discuss the potential regulatory mechanisms whereby apoptotic resistance is involved in these protective pathways. [Int J Biochem Cell Biol] Abstract
