Special Issue Information

Dear Colleagues,

Pancreatitis (both acute and chronic) is a complex disease that can be caused by genetic and/or environmental factors. Since the identification of a gain-of-function missense variant in the PRSS1 gene as a cause of hereditary pancreatitis in 1996, a diverse array of inherited variants in more than 10 genes/loci (including CFTR, SPINK1, CTRC, CPA1, CEL, CTRB1-CTRB2, CELA3B, PNLIP, CLDN2 and TRPV6) have been reported to cause or predispose to hereditary, familial, idiopathic and/or alcoholic chronic pancreatitis. Most of the known pancreatitis genes encode pancreatic zymogens that are specifically expressed in the pancreatic acinar cells; the corresponding pathogenic variants operate either through a trypsin- or misfolding-dependent pathway. Moreover, hypertriglyceridemia-induced acute pancreatitis is often predisposed by variants in LPL, APOC2, APOA5, GPIHBP1 and LMF1 genes. These genetic findings not only provided penetrating insights into the pathogenesis of pancreatitis, but also served as the basis for personalized prevention and treatment. Nonetheless, some reported gene associations remain to be replicated, the pathogenic mechanisms underlying some replicated disease associations remain to be elucidated, the pathogenic relevance of many genetic variants remains to be determined, and new disease genes remain to be discovered. This Special Issue welcomes all types of contributions that improve our understanding of the genetics of acute and chronic pancreatitis, including but not limited to topics such as genotype–phenotype relationship, gene–environment interaction, new gene and variant discovery, as well as genetic animal models of pancreatitis.

Oxidative stress has been implicated in the initiation of acute pancreatitis (AP). HDL is considered to be a preventing factor against cell membrane oxidation, thanks to the presence on its surface of apolipoprotein A-I (apoA-I) and paraoxonase-1 (PON1), which activity can be modified by genetic and environmental factors. The impact of SNP rs662 in the PON1 gene and SNP rs670 and rs5069 in the APOAI gene on PON1 activities and its concentration in the population of AP patients and healthy volunteers was investigated. In the group of patients with AP, a decreased HDL concentration and PON1 activities were observed. A decrease in the aryloesterase and lactonase activities of PON1 in AP patients with the TT genotype for SNP rs662 (especially in smokers) was found. In the group of patients with the AA genotype (rs670), the highest concentrations of HDL and apoA-I were observed, which were gradually decreasing in the course of AP. Changes in the concentration of apoA-I were associated with the changes in the concentration and activities of PON1 in the AP patients with the AA genotype for SNP rs670. A decreasing apoA-I concentration contributing to lowering PON1 concentration and its activities during the hospitalization of AP patients with the CC genotype for SNP rs5069 were shown. Therefore, more susceptibility of persons with the CC genotype for SNP rs5069 to pro/antioxidative imbalance was shown. In this process, an important role was played by the HDL level and its interaction with PON1 and apoA-I. Full article

Chronic pancreatitis (CP) is a fibroinflammatory disorder of the pancreas. Our understanding of CP pathogenesis is partly limited by the incomplete characterization of pancreatic cell types. Here, we performed single-cell RNA sequencing on 3825 cells from the pancreas of one control mouse and mice with caerulein-induced CP. An analysis of the single-cell transcriptomes revealed 16 unique clusters and cell type-specific gene expression patterns in the mouse pancreas. Sub-clustering of the pancreatic mesenchymal cells from the control mouse revealed four clusters of cells with specific gene expression profiles (combinatorial expressions of Smoc2, Cxcl14, Tnfaip6, and Fn1). We observed that immune cells in the pancreas of the CP mice were abundant and diverse in cellular type. Compared to the control, 547 upregulated genes (including Mmp7, Ttr, Rgs5, Adh1, and Cldn2) and 257 downregulated genes were identified in ductal cells from the CP group. The elevated expression levels of MMP7 and TTR were further verified in the pancreatic ducts of CP patients. This study provides a preliminary description of the single-cell transcriptome profiles of mouse pancreata and accurately demonstrates the characteristics of pancreatic ductal cells in CP. The findings provide insight into novel disease-specific biomarkers and potential therapeutic targets of CP. Full article
