Abstract
Pancreatic ductal adenocarcinoma (PDAC) has a minimal (<15%) 5-year existence, in part due to resistance to chemoradiotherapy. Previous research reveals the impact of paricalcitol (P) and hydroxychloroquine (H) on altering the lysosomal fusion, decreasing stromal burden, and triggering PDAC to chemotherapies. This investigation aims to elucidate the molecular properties of the H and P combination and their potential in sensitizing PDAC to gemcitabine (G). PH potentiates the effects of G in in vitro, orthotopic mouse models, and a patient-derived xenograft model of PDAC. Proteomic and single-cell RNA sequencing (RNA-seq) analyses reveal that GPH treatment upregulates autophagy and endoplasmic reticulum (ER) stress-related transcripts. GPH treatment decreases the number of Ki67, fibroblast-associated protein (FAP), and alpha-smooth muscle actin (SMA)-expressing fibroblasts with a decrease in autophagy-related transcripts. The GPH treatment increases M1 polarization and CD4+ and CD8+ T cells and reduces CD4+ and CD8+ regulatory T cells (Tregs). These effects of GPH were confirmed in paired biopsies obtained from patients treated in a clinical trial (NCT04524702).

期刊介绍:
Cell Reports Medicine is an esteemed open-access journal by Cell Press that publishes groundbreaking research in translational and clinical biomedical sciences, influencing human health and medicine.
Our journal ensures wide visibility and accessibility, reaching scientists and clinicians across various medical disciplines. We publish original research that spans from intriguing human biology concepts to all aspects of clinical work. We encourage submissions that introduce innovative ideas, forging new paths in clinical research and practice. We also welcome studies that provide vital information, enhancing our understanding of current standards of care in diagnosis, treatment, and prognosis. This encompasses translational studies, clinical trials (including long-term follow-ups), genomics, biomarker discovery, and technological advancements that contribute to diagnostics, treatment, and healthcare. Additionally, studies based on vertebrate model organisms are within the scope of the journal, as long as they directly relate to human health and disease.
