Human Trypsin-3 (PRSS3) ELISA kit

1. PRSS3 is downregulated by intragenic hypermethylation in HCC. * Epigenetic silencing of PRSS3 facilitates growth, migration, and invasion of HCC. * PRSS3 intragenic methylation has implication in diagnosis of HCC. PMID: 28844099
2. PRSS3 acts as an oncogene in invasive ductal carcinoma of the breast development and progression PMID: 28423522
3. Study developed a new high resolution crystal structure of mesotrypsin complexed with diminazene through a structure-based molecular docking screen that could help facilitate derivatization efforts, addressing current pan-inhibition of human trypsins through rigidification of diminazene to select for a conformation that maximizes interactions with the non-conserved Arg-193 residue. PMID: 28463992
4. Data show that silencing tumor-endothelial cells (EC) for trypsinogen 4 accumulated tissue factor pathway inhibitor-2 (TFPI-2) in the matrix. PMID: 26318044
5. These findings suggest that inhibitor cleavage represents a functional adaptation of mesotrypsin that may have evolved in response to positive selection pressure. PMID: 26175157
6. High PRSS3 expression in EOC tissues was significantly associated with advanced FIGO stage and lymph node metastasis. PMID: 25735255
7. Data suggest that mesotrypsin cleavage of Kunitz domains may contribute to cancer progression. PMID: 25301953
8. 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. PMID: 24872419
9. extra-pancreatic trypsinogen 3 is produced by esophageal adenocarcinoma cells and activates PAR-2 in an autocrine manner. PMID: 24146905
10. IFN regulatory factor 2 (Irf2) has a regulatory role in trypsinogen5 gene transcription, which is resistant to a major endogenous trypsin inhibitor, Spink3 PMID: 22042864
11. Report PRSS3/mesotrypsin upregulation in breast cancer cells and identify CD109 as the functional proteolytic target of mesotrypsin. PMID: 20035377
12. PRSS3 plays an important role in the progression, metastasis and prognosis of human pancreatic cancer. PMID: 20947888
13. Investigation did not reveal an association between PRSS3 variants and chronic pancreatitis. PMID: 20484962
14. 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 PMID: 19924134
15. 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. PMID: 19920152
16. X-ray structure in complex with the inhibitor benzamidine at 1.7 A resolution; crystal structure reveals basis for inhibitor resistance PMID: 11827488
17. biological function of human mesotrypsin is digestive degradation of trypsin inhibitors PMID: 14507909
18. The results classify E32del mesotrypsinogen as a frequent polymorphic variant, which is not associated with chronic alcoholic pancreatitis PMID: 15855826
19. PRSS3 promoter methylation is associated with advanced bladder cancer PMID: 15987713
20. 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. PMID: 16013053
21. 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. PMID: 16412431
22. analysis of structural rearrangement during the acylation step in human trypsin 4 on 4-methylumbelliferyl 4-guanidinobenzoate substrate analogue PMID: 16492676
23. 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 PMID: 16759229
24. 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. PMID: 17406981
25. 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. PMID: 17623652
26. 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. PMID: 18363639
27. Absence of mesotrypsinogen gene (PRSS3) copy number variations in patients with chronic pancreatitis. PMID: 18665091
28. 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. PMID: 19249338
