Abstract
Chronic pancreatitis (CP) as a progressive inflammatory disorder, remains untreatable. The novel treatment strategy for CP is imperative. We attempted to explore the therapeutic biomarkers for CP. The single-cell sequencing data were retrieved from Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) in idiopathic CP were identified, followed by function and pathway annotation, and PPI network established. DEGs of interest were verified in human tissue samples. The function of candidate biomarker was determined in the murine model with CP. A total of 208 genes were specially differentially expressed in idiopathic patients. Functional enrichment analysis showed DEGs were mainly enriched in glycogen catabolic process, RNA splicing, and glucagon signaling pathway. A PPI network centered on HDAC1 was constructed. HDAC1 was overexpressed in CP patients. The murine model with CP was induced by repetitive cerulein treatment. Silencing sh-HDAC1 treatment reversed cerulein-induced inflammatory cells accumulation, high expression of TGF-β1, and collagen 1 in pancreas in vivo. HDAC1 might be served as potential biomarker for CP. The present study provided insights into the molecular mechanism of CP that may be useful in further investigations.

Inherited pancreatic exocrine insufficiency and pancreatitis: When children transition to adult care. Best Pract Res Clin Gastroenterol 2021; 56-57:101782. [PMID: 35331395 DOI: 10.1016/j.bpg.2021.101782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 11/09/2021] [Accepted: 12/07/2021] [Indexed: 01/31/2023]
Abstract
Hereditary pancreatitis (HP) encompasses two distinct disease groups: the first manifests as congenital exocrine pancreatic insufficiency (EPI), and the second includes hereditary forms of pancreatitis. EPI represents the ultimate expression of gland function loss. Cystic fibrosis is by far the most frequent aetiology of early-onset EPI; genetics and a growing understanding of the disease mechanisms have paved the way for innovative and personalized treatment approaches. Efforts are ongoing to further decipher the pathophysiology and explore new therapies for other causes of EPI. HP occurs in patients carrying mutations in genes encoding digestive proteases or proteins playing an important role in proper pancreatic function and homeostasis. Improved sequencing techniques have led to the discovery of several causal and disease promoting genes. Most forms of HP have a paediatric onset but complications usually manifest during adulthood. Surveillance in experienced centres is mandatory to diagnose and address these complications in a timely manner.

A high prevalence of genetic polymorphisms in idiopathic and alcohol-associated chronic pancreatitis patients in Ireland. HPB (Oxford) 2021; 23:231-237.

Abstract
BACKGROUND Individual genetic architecture is considered central to susceptibility and progression of disease in chronic pancreatitis. The study aimed to evaluate the presence of common pancreatic gene mutations in a defined cohort of idiopathic and alcohol-induced chronic pancreatitis patients in Ireland. METHODS The study comprised patients with idiopathic and alcohol-induced chronic pancreatitis and historic controls. Variants in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, cationic trypsinogen (PRSS1) gene and serine protease inhibitor kazal type-1 (SPINK1) gene, were assessed by Taqman© genotyping assay. RESULTS Of n = 126 patients and n = 167 controls, mutations were detected in 23 (20%) and in 10 (6%) respectively (P < 0.001). The majority of mutations found were in the SPINK1 gene variant N34S (13%) which increased disease risk almost six-fold (OR 5.9). Neither CFTR severe mutation (F508del) (P = 0.649) nor mild variant (R117H) (P = 0.327) were over-represented amongst patients compared to control subjects. PRSS1 variants were not detected in either patient or control subjects. CONCLUSION There was a significant prevalence of chronic pancreatitis-associated gene mutations in this well-phenotyped cohort. In patients with alcohol-related or idiopathic chronic pancreatitis, the possibility of genetic mutations in the SPINK 1 gene should be considered as a contributing aetiology factor.

Clinical interpretation of PRSS1 variants in patients with pancreatitis. Clin Res Hepatol Gastroenterol 2021; 45:101497.

Abstract
Since the description of the PRSS1 gene encoding the cationic trypsinogen as being involved in dominant hereditary pancreatitis, more than 50 PRSS1 variants have been reported. Among the PRSS1 variants that have been classified as pathogenic, some have a high penetrance and others have a low penetrance. Assessing the clinical relevance of PRSS1 variants is often complicated in the absence of functional evidence and interpretation of rare variants is not very easy in clinical practice. The aim of this study was to review the different variants identified in the PRSS1 gene and to classify them according to their degree of deleterious effect. This classification was based on the results of several in vitro experiments and on population data, in comparing the allelic frequency of each variant in patients with pancreatitis and in unaffected individuals. This review should help geneticists and clinicians in charge of patient's care and genetic counseling to interpret molecular results.

Abstract
Premature activation of digestive enzymes in the pancreas has been linked to development of pancreatitis for more than a century. Recent development of novel models to study the role of pathologic enzyme activation has led to advances in our understanding of the mechanisms of pancreatic injury. Colocalization of zymogen and lysosomal fraction occurs early after pancreatitis-causing stimulus. Cathepsin B activates trypsinogen in these colocalized organelles. Active trypsin increases permeability of these organelles resulting in leakage of cathepsin B into the cytosol leading to acinar cell death. Although trypsin-mediated cell death leads to pancreatic injury in early stages of pancreatitis, multiple parallel mechanisms, including activation of inflammatory cascades, endoplasmic reticulum stress, autophagy, and mitochondrial dysfunction in the acinar cells are now recognized to be important in driving the profound systemic inflammatory response and extensive pancreatic injury seen in acute pancreatitis. Chymotrypsin, another acinar protease, has recently been shown be play critical role in clearance of pathologically activated trypsin protecting against pancreatic injury. Mutations in trypsin and other genes thought to be associated with pathologic enzyme activation (such as serine protease inhibitor 1) have been found in familial forms of pancreatitis. Sustained intra-acinar activation of nuclear factor κB pathway seems to be key pathogenic mechanism in chronic pancreatitis. Better understanding of these mechanisms will hopefully allow us to improve treatment strategies in acute and chronic pancreatitis.
