    Acinar Cell Clonal Expansion in Pancreas Homeostasis and Carcinogenesis

    Using lineage tracing from the endogenous telomerase reverse transcriptase (Tert) locus, scientists identified a rare TERT-positive subpopulation of pancreatic acinar cells dispersed throughout the exocrine compartment.

    A Microenvironment-Inspired Synthetic Three-Dimensional Model for Pancreatic Ductal Adenocarcinoma Organoids

    Experimental in vitro models that capture pathophysiological characteristics of human tumors are essential for basic and translational cancer biology. Researchers described a fully synthetic hydrogel extracellular matrix designed to elicit key phenotypic traits of the pancreatic environment in culture.

    KARATE: PKA-Induced KRAS4B-RHOA-mTORC2 Supercomplex Phosphorylates AKT in Insulin Signaling and Glucose Homeostasis

    By investigating insulin receptor signaling in human cells and biochemical reconstitution, scientists found that insulin induced the activation of mTORC2 toward AKT by assembling a supercomplex with KRAS4B and RHOA GTPases, termed KARATE (KRAS4B-RHOA-mTORC2 Ensemble).

    A Putative Long Noncoding RNA-Encoded Micropeptide Maintains Cellular Homeostasis in Pancreatic β Cells

    Investigators experimentally verified one such micropeptide encoded by a β cell- and neural cell-enriched lncRNA TCL1 upstream neural differentiation-associated RNA. They provided the first evidence that lncRNA-encoded micropeptides played a critical role in pancreatic β cell functions.

    Proteogenomic Characterization of Pancreatic Ductal Adenocarcinoma

    Toward understanding the underlying molecular alterations that drive pancreatic ductal adenocarcinoma oncogenesis, scientists conducted comprehensive proteogenomic analysis of 140 pancreatic cancers, 67 normal adjacent tissues, and 9 normal pancreatic ductal tissues.

    MUC5AC Serves as the Nexus for β-Catenin/C-Myc Interplay to Promote Glutamine Dependency during Pancreatic Cancer Chemoresistance

    Murine and human pancreatic 3D-tumoroids were used to evaluate gemcitabine’s efficacy in combination with β-catenin and glutaminolysis inhibitors.

    LINC00261 Elevation Inhibits Angiogenesis and Cell Cycle Progression of Pancreatic Cancer Cells by Upregulating SCP2 via Targeting FOXP3

    Long non-coding RNAs biological functions and molecular mechanisms associated with pancreatic cancer (PC) remain to be poorly elucidated. Researchers clarified the role of lncRNA LINC00261 in PC and confirmed its regulatory mechanisms.

    Comprehensive Analysis of the Transcriptional Expressions and Prognostic Value of S100A Family in Pancreatic Ductal Adenocarcinoma

    The authors investigated the transcriptional expressions, methylation level and prognostic value of S100As in pancreatic ductal adenocarcinoma (PDAC) patients. Real-time PCR was used to detect the expressions of S100A2/4/6/10/14/16 in four pancreatic cancer cell lines and pancreatic cancer tissues from PDAC patients undergoing surgery.

    CCL2 Produced by Pancreatic Ductal Adenocarcinoma Is Essential for the Accumulation and Activation of Monocytic Myeloid-Derived Suppressor Cells

    Investigators compared normal pancreatic tissues with pancreatic ductal adenocarcinoma tissues according to The Cancer Genome Atlas and clinical samples. Flow cytometry was used to identify monocytic myeloid-derived suppressor cells.
