Single-cell transcriptome analysis identifies MIF as a novel tumor-associated neutrophil marker for pancreatic ductal adenocarcinoma.

ABSTRACT: Pancreatic cancer is a common cause of cancer mortality, and pancreatic ductal adenocarcinoma (PDAC) is the most common subtype. Tumor-associated neutrophils (TANs) have been recognized as potential therapeutic targets. In this study, we utilized bulk and single-cell RNA sequencing (scRNA‒seq) to identify seven distinct subtypes of neutrophils in PDAC. Oxidized low-density lipoprotein receptor 1 (OLR1)+ neutrophils and macrophage migration inhibitory factor (MIF)+ neutrophils were classified as TANs. The clinical relevance, dynamic transitional process, function, cell‒cell communication and transcription factor activity of neutrophil subclusters in PDAC were characterized. Furthermore, the novel MIF+ TANs were fully validated in PDAC tissues, an orthotopic pancreatic tumor model and a pati
