Researchers Identify Gene that Pushes Normal Pancreas Cells to Change Shape, a Key Step to Cancer Development
Investigators have identified a molecule that pushes normal pancreatic cells to transform their shape, laying the groundwork for development of pancreatic cancer – one of the most difficult tumors to treat. [Press release from Mayo Clinic discussing publication in Nature Communications] Press Release | Abstract

Insulin Secretory Granules Control Autophagy in Pancreatic β Cells
In contrast to many mammalian cells, macroautophagy in pancreatic β cells was suppressed upon starvation. Starved β cells induced lysosomal degradation of nascent secretory insulin granules, which was controlled by protein kinase D, a key player in secretory granule biogenesis. [Science] Abstract

Feedback Inhibition of CREB Signaling Promotes Beta Cell Dysfunction in Insulin Resistance
Scientists showed that mice with a knockout of the CREB coactivator CRTC2 in beta cells have impaired oral glucose tolerance due to decreases in circulating insulin concentrations. CRTC2 was found to promote beta cell function in part by stimulating the expression of the transcription factor MafA. [Cell Rep]

Alginate Encapsulant Incorporating CXCL12 Supports Long-Term Allo- and Xenoislet Transplantation without Systemic Immune Suppression
Researchers investigated the effect of alginate microcapsules incorporating CXCL12 on islet function. Coating of islets with CXCL12 or microencapsulation of islets with alginate incorporating the chemokine, resulted in long-term allo- and xenoislet survival and function, as well as a selective increase in intragraft regulatory T cells. [Am J Transplant] Abstract | Press Release

Ets-1 as an Early Response Gene against Hypoxia-Induced Apoptosis in Pancreatic β-Cells
Scientists identified the transcription factor Ets-1 (v-ets erythroblastosis virus E26 oncogene homolog 1) as an early response gene against hypoxia-induced apoptosis in pancreatic β-cells. [Cell Death Dis] Full Article

Compensatory Hyperinsulinemia in High-Fat Diet-Induced Obese Mice Is Associated with Enhanced Insulin Translation in Islets
Scientists investigated whether insulin synthesis was altered in correlation with a high-fat diet, for the purpose of obtaining further understanding of the compensatory mechanisms in pancreatic β-cells. [Biochem Biophys Res Commun] Abstract


Antitumor Effect of Anti-Tissue Factor Antibody-MMAE Conjugate in Human Pancreatic Tumor Xenografts
Researchers investigated the anti-tumor effect of an antibody-drug conjugate (ADC) consisting of an anti-tissue factor monoclonal antibody and monomethyl auristatin E (MMAE). The cytotoxic and antitumor effects of the ADCs against four pancreatic cancer cell lines were analyzed. [Int J Cancer] Abstract | Full Article

Tenascin-C Induces Resistance to Apoptosis in Pancreatic Cancer Cells through Activation of ERK/NF-κB Pathway
Scientists performed an analysis to determine the effects of tenascin-C on modulating cell apoptosis and chemo-resistance and explored its mechanisms involving activation in pancreatic cancer cells. [Apoptosis] Abstract

Hexon Modification to Improve the Activity of Oncolytic Adenovirus Vectors against Neoplastic and Stromal Cells in Pancreatic Cancer
Scientists inserted the TGFβ receptor targeting peptide CKS17 into the hypervariable region 5 of the capsid protein hexon with the aim to generate a replicating Ad vector with improved activity in complex tumors. They demonstrated increased transduction of both pancreatic cancer cell lines and of pancreatic stellate cells and enhanced cytotoxicity in co-cultures of both cell types. [PLoS One] Full Article

The Epigenetic Agents Suberoylanilide Hydroxamic Acid and 5-AZA-2′ Deoxycytidine Decrease Cell Proliferation, Induce Cell Death and Delay the Growth of MiaPaCa2 Pancreatic Cancer Cells In Vivo
Treatment with histone deacetylase inhibitors and DNA methyltransferase inhibitors decreased cell proliferation in MiaPaCa2 cells, and suberoylanilide hydroxamic acid treatment, with or without 5-AZA-2′ deoxycytidine (5-AZA-dc), resulted in higher cell death and lower DNA synthesis compared to 5-AZA-dc alone and controls. [Int J Oncol] Abstract

Oncogenic miR-23a in Pancreatic Ductal Adenocarcinogenesis via Inhibiting APAF1
Ectopic miR-23a significantly suppressed the APAF1 gene expression in pancreatic cancer cells. Similar to siAPAF1, miR-23a significantly promoted pancreatic cancer cell proliferation and repressed apoptosis. [Dig Dis Sci] Abstract

Novel Directions in Neoadjuvant Therapy for Pancreas Adenocarcinoma
The authors examine the historical precedent as well as the current state of affairs regarding neoadjuvant therapy in resectable and borderline resectable pancreatic adenocarcinoma. In addition, they review the definitions for resectable and borderline resectable disease and highlight key areas of clinical investigation in the field and summarize the major ongoing neoadjuvant studies focused on resectable pancreatic adenocarcinoma.
