A humanized PRSS1 transgenic mouse was established and treated with caerulein to mimic the development of CP, as evidenced by pathogenic alterations, collagen deposition, and increased expression of the inflammatory factors IL-6, IL-1β, and TNF-α.
Results demonstrated that apelin inhibited the up-regulation of pancreatic tumor necrosis factor α, macrophage inflammatory protein-1 α/β, and IL-1β expression significantly in mice with CP.
MicroRNAs play important roles in the development and progression of many human diseases. mir-146a could significantly suppress the induction of proinflammatory cytokines IL-1β, IL-6, TNF-α, NF-κB and chemokine MCP-1, which might play important roles in chronic pancreatitis.
The aim of our study was to assess the clinical significance of -308G/ATNF-alpha and +874A/T INF-gamma genes polymorphisms as well as TNF-alpha and INF-gamma serum levels in pancreatic adenocarcinoma (PA) and chronic pancreatitis (CP) as regards to healthy volunteers.
We sought to study the frequency of peptic ulcer, the association of peptic ulcer with H. pylori and host TNF-alpha promoter haplotype in AIP and nonautoimmune chronic pancreatitis.
No associations were identified between SNPs in the promoter regions of the IL-1beta, IL-6, or TNFalpha proinflammatory cytokines genes or the TGFbeta1 and VEGF genes and susceptibility to CP.
The aims of this study were to describe and compare the frequencies of polymorphisms on the interleukin (IL)-6, IL-10, tumor necrosis factor (TNF)-alpha, transforming growth factor (TGF)-beta1, and interferon (IFN)-gamma genes between patients with chronic pancreatitis (CP) and healthy individuals from Bahia, Brazil.
The frequencies of the promotor polymorphisms of IL10-627A, IL10-1117A, TNF-238A and TNF-308A in patients with alcoholic chronic pancreatitis, idiopathic pancreatitis, SPINK1-N34S-associated chronic pancreatitis and pancreatic cancer did not differ significantly from the control group.
