    Generation of Human Islet Cell Type-Specific Identity Genesets

    Scientists showed the efficacy of genesets describing the identity of human α-, β-, γ- and δ-cells to outline cell identity changes and unraveled some of their underlying genetic mechanisms, whether during embryonic pancreas development or in experimental setups aimed at developing glucose-responsive insulin-secreting cells.

    Essential Role of Lysosomal Ca2+-Mediated TFEB Activation in Mitophagy and Functional Adaptation of Pancreatic β-Cells to Metabolic Stress

    Researchers investigated the changes of lysosomal Ca2+ by mitochondrial or metabolic stress that could modulate transcription factor EB (TFEB) activation and, additionally, the role of TFEB-induced mitophagy in β-cell function.

    Abstract

    Long-Term Feeder-Free Culture of Human Pancreatic Progenitors on Fibronectin or Matrix-Free Polymer Potentiates β Cell Differentiation

    The authors reported on a protocol enabling a long-term expansion of human pancreatic progenitors in a defined medium on fibronectin, in the absence of feeder layers.

    Circular RNA Circ-MTHFD1L Induces HR Repair to Promote Gemcitabine Resistance via the miR-615-3p/RPN6 Axis in Pancreatic Ductal Adenocarcinoma

    Researchers screened the differentially expressed circRNAs in human pancreatic cancer cell lines and gemcitabine resistant pancreatic cancer cell lines and discovered a new gemcitabine resistant-related molecule in pancreatic cancer.
