26318044 Data show that silencing tumor-endothelial cells (EC) for trypsinogen 4 accumulated tissue factor pathway inhibitor-2 (TFPI-2) in the matrix.
26175157 These findings suggest that inhibitor cleavage represents a functional adaptation of mesotrypsin that may have evolved in response to positive selection pressure.
25735255 High PRSS3 expression in EOC tissues was significantly associated with advanced FIGO stage and lymph node metastasis.
25301953 Data suggest that mesotrypsin cleavage of Kunitz domains may contribute to cancer progression.
24872419 Mesotrypsin generated saposins A-D from prosaposin, and mature caspase-14 contributed to this process by activating mesotrypsinogen to mesotrypsin. Knockdown of these proteases markedly down-regulated saposin A synthesis in skin equivalent models.
24146905 extra-pancreatic trypsinogen 3 is produced by esophageal adenocarcinoma cells and activates PAR-2 in an autocrine manner.
22042864 IFN regulatory factor 2 (Irf2) has a regulatory role in trypsinogen5 gene transcription, which is resistant to a major endogenous trypsin inhibitor, Spink3
20947888 PRSS3 plays an important role in the progression, metastasis and prognosis of human pancreatic cancer.

20035377 Report PRSS3/mesotrypsin upregulation in breast cancer cells and identify CD109 as the functional proteolytic target of mesotrypsin.
19924134 Because mesotrypsin is resistant to naturally occurring trypsin inhibitors, confined expression of the isoforms of mesotrypsinogens and enteropeptidase may indicate that mesotrypsin is involved in keratinocyte terminal differentiation
19920152 Processing by mesotrypsin may ablate the protease inhibitory function of APP/protease nexin 2 in vivo and may also modulate other activities of APP/protease nexin 2 that involve the Kunitz domain.
19249338 Here, we report that nexin-1 inhibits trypsin-4, and forms stable complexes only with this trypsin-isoenzyme. This result suggests that nexin-1 could modulate trypsin activity in brain where both nexin-1 and trypsin-4 are expressed.
18665091 Absence of mesotrypsinogen gene (PRSS3) copy number variations in patients with chronic pancreatitis.
18363639 This study reveals enhanced mRNA expression of trypsinogen IV and SERT and a higher 5-HT content in the small intestine of IBS patients compared to healthy subjects.
17623652 trypsin IV and p23 are inhibitor-resistant trypsins that can cleave and activate PARs, causing PAR(1)- and PAR(2)-dependent inflammation and PAR(2)-dependent hyperalgesia.
17406981 human trypsinogen 4 is widely but unevenly distributed in the human brain. It is localized in neurons and glial cells, predominantly in astrocytes & the extracellular matrix.
16759229 mesotrypsin cannot activate pancreatic zymogens, but might activate certain proteinase-activated receptors because of its thrombin-like subsite specificity; alpha1AT Pittsburgh is an effective mesotrypsin inhibitor
16492676 analysis of structural rearrangement during the acylation step in human trypsin 4 on 4-methylumbelliferyl 4-guanidinobenzoate substrate analogue
16412431 Results suggest that human trypsin 4 may be one of the candidate proteases involved in the pathomechanism of multiple sclerosis via cleavage of myelin basic protein.
16013053 we determined the promoter hypermethylation status of PRSS3 in a case series study of primary NSCLC, and found methylation of this gene to be common, occurring in 53% (86 of 166) of tumors examined.
15987713 PRSS3 promoter methylation is associated with advanced bladder cancer
15855826 Observational study of gene-disease association. (HuGE Navigator)
15855826 The results classify E32del mesotrypsinogen as a frequent polymorphic variant, which is not associated with chronic alcoholic pancreatitis
14507909 biological function of human mesotrypsin is digestive degradation of trypsin inhibitors
11827488 X-ray structure in complex with the inhibitor benzamidine at 1.7 A resolution; crystal structure reveals basis for inhibitor resistance
