    GRK2 Contributes to Glucose Mediated Calcium Responses and Insulin Secretion in Pancreatic Islet Cells

    Utilizing Min6 cells, a pancreatic ß-cell model, scientists knocked down G-protein coupled receptor kinase 2 (GRK2) and measured glucose-mediated intracellular calcium responses and insulin secretion.

    Pronounced Proliferation of Non-Beta Cells in Response to Beta-Cell Mitogens in Isolated Human Islets of Langerhans

    Islets were kept intact or dispersed into single cells and cultured in the presence of harmine, glucose, or heparin-binding epidermal growth factor-like growth factor (HB-EGF), and subsequently analyzed by immunohistochemistry or flow cytometry.

    In Vitro Assessment of a Synergistic Combination of Gemcitabine and Zebularine in Pancreatic Cancer Cells

    Researchers investigated the effect of a cytidine deaminase inhibitor – Zebularine on anticancer activity of Gemcitabine in pancreatic cancer cell lines MiaPaCa-2, BxPC-3, and Panc-1. Zeb treatment synergistically increased Gem-induced cytotoxicity in all three pancreatic cancer cell lines.

    Apolipoprotein E Promotes Immune Suppression in Pancreatic Cancer through NF-kB-Mediated Production of CXCL1

    Investigators reported that Apolipoprotein E (ApoE) was elevated in peripheral blood monocytes in pancreatic ductal adenocarcinoma patients, and plasma ApoE protein levels stratified patient survival.

    Abstract

    A Transcriptionally Distinct Subpopulation of Healthy Acinar Cells Exhibit Features of Pancreatic Progenitors and Pancreatic Ductal Adenocarcinoma

    Scientists re-analyzed multiple pancreas and pancreatic ductal adenocarcinoma single-cell RNA-seq datasets and found a subset of non-malignant acinar cells, which they refered to as acinar edge cells, whose transcriptomes highly diverged from a typical acinar cell in each dataset.

    Abstract

    Pancreatic Cancer Intrinsic PI3Kα Activity Accelerates Metastasis and Rewires Macrophage Component

    Researchers searched for a gene signature that discriminate localized pancreatic ductal adenocarcinoma (PDAC) from confirmed metastatic PDAC and devised a preclinical protocol using circulating cell-free DNA (cfDNA) as an early biomarker of micro-metastatic disease to validate the identification of key signaling events.
