    KRASMG12D Inhibition Reprograms the Microenvironment of Early and Advanced Pancreatic Cancer to Promote FAS-Mediated Killing by CD8+ T Cells

    Scientists demonstrated that MRTX1133 reverses early PDAC growth, increased intratumoral CD8+ effector T cells, decreases myeloid infiltration, and reprogramed cancer-associated fibroblasts.

    Modeling Islet Enhancers Using Deep Learning Identifies Candidate Causal Variants at Loci Associated with T2D and Glycemic Traits

    Focusing on pancreatic islets, a type 2 diabetes (T2D) relevant tissue, researchers showed that their model learned islet-specific transcription factor regulatory patterns and could be used to prioritize candidate causal variants.

    Targeting BCAA Metabolism to Potentiate Metformin’s Therapeutic Efficacy in the Treatment of Diabetes in Mice

    Mice were treated with vehicle or metformin for more than four weeks to investigate the effects of metformin in vivo. In vitro, primary mouse hepatocytes and HepG2 cells were treated with two mmol/l metformin.

    Impact of Butylparaben on β-Cell Damage and Insulin/PEPCK Expression in Zebrafish Larvae: Protective Effects of Morin

    Researchers investigated the potential protective mechanism of morin against oxidative stress-induced damage caused by butylparaben (BP) in zebrafish larvae. They exposed the zebrafish larvae to BP or five days, leading to increased oxidative stress and apoptosis in β-cells. However

    Biological Activity of Recombinant Human PDX1 Protein Produced from Escherichia coli

    Investigators reported the bioactivity of the purified human pancreatic and duodenum homeobox 1 (PDX1) fusion protein using various assays like cell migration, proliferation, cell cycle analysis, and gene expression.

    Single Cell Transcriptomic Analyses Implicate an Immunosuppressive Tumor Microenvironment in Pancreatic Cancer Liver Metastasis

    Scientists presented the single-cell transcriptomic landscape of synchronously resected pancreatic ductal adenocarcinoma primary tumors and matched liver metastases. They performed comparative analysis on both cellular composition and functional phenotype between primary and metastatic tumors.

    SMC3 Epigenetic Silencing Regulates Rab27a Expression and Drives Pancreatic Cancer Progression

    To assess the mechanism that regulate Rab27a expression in PDAC, researchers used PDAC cell lines. The biological significance of these findings was validated in PDAC genetically engineered mouse models and human samples.

    Integrative Proteomics and N-glycoproteomics Reveal the Synergistic Anti-tumor Effects of Aspirin- and Gemcitabine-Based Chemotherapy on Pancreatic Cancer Cells

    The authors found that the addition of aspirin enhanced the inhibitory effect of gemcitabine on the activity of PANC-1 and BxPC-3 cells. Quantitative N-glycoproteome, proteome, phosphorylation, and transcriptome data were obtained from integrated multi-omics analysis to evaluate the anti-tumor effects of aspirin and gemcitabine on pancreatic cancer cells.
