<h3>Objective</h3> Growing evidence suggests that a phenotypic switch converting pancreatic acinar cells to duct-like can lead intraepithelial neoplasia and eventually invasive ductal adenocarcinoma. Histologically, the onset of this is characterised by co-expression markers in acini, lesion called acinar-to-ductal metaplasia (ADM). The transcriptional regulators required initiate ADM are unknown, but need be identified characterise regulatory networks drive ADM. In study, role transcription...
The COVID-19 pandemic has caused significant mortality and morbidity around the world. Although effective vaccines have been developed, large parts of world remain unvaccinated while new SARS-CoV-2 strains keep emerging.
Abstract Nerves are a notable feature of the tumor microenvironment in some epithelial tumors, but their role malignant progression pancreatic ductal adenocarcinoma (PDAC) is uncertain. Here, we identify dense innervation precancerous lesions, known as intraepithelial neoplasms (PanIN), and describe unique subpopulation neuroendocrine PanIN cells that express neuropeptide substance P (SP) receptor neurokinin 1-R (NK1-R). Using organoid culture, demonstrated sensory neurons promoted...
<h3>Objective</h3> The transcription factor SOX9 was recently shown to stimulate ductal gene expression in pancreatic acinar-to-ductal metaplasia and accelerate development of premalignant lesions preceding adenocarcinoma (PDAC). Here, we investigate how operates tumourigenesis. <h3>Design</h3> We analysed genomic transcriptomic data from surgically resected PDAC extended the analysis xenografts samples cell lines. manipulated human lines mouse models developing PDAC. <h3>Results</h3> found...

Abstract Inflammation in the context of pancreatic injury drives acinar-to-ductal metaplasia (ADM), a cell state that can be hijacked by mutant Kras to drive formation cancer. ADM has been described alternatively bear progenitor features, but extent which lineage reversion is broad feature response and early tumorigenesis - particularlyacross different alleles remains poorly understood. Herein we implement novel Ptf1a-tdTomato mice characterize late progenitors serve as benchmarks define...
Renal functions are regulated by steroid sex hormones, but the exhaustive identification of their receptors along nephron is still lacking. Here, we have localized all known nuclear or membrane‐bound hormone and some activators male female mice. Almost present in kidney, them having very restricted localization. Only one gene tested among 11 (ARA54) exhibits a gender difference level its expression. This first “renal map” receptor expression may serve as pre‐requisite for investigating role...
SUMMARY Inflammation is essential to the disruption of tissue homeostasis, and, in pancreas, can destabilize identity terminally differentiated acinar cells. Herein we employ lineage-traced mouse models delineate chromatin dynamics that accompany cycle metaplasia and regeneration following pancreatitis, unveil presence an epigenetic memory inflammation pancreatic cell compartment. We observe despite histologic resolution cells fail return their molecular baseline after several months,...
Abstract The transcription factor SOX9 has recently been shown to have a role in the ontogenesis of pancreatic ductal adenocarcinoma (PDAC) through metaplastic changes acinar cells. Nevertheless, mechanisms which operates remain be explored. We analyzed genomic and transcriptomic data from cohort surgically resected cases PDAC (n=90) Australian Pancreatic cancer Genome Initiative (APGI). Genetic aberrations (mutation copy number changes) gene were found 15% patient tumors. Protein expression...
