In PPJ collected from healthy subjects no significant degradation was observed by incubating PPJ at 37\u00b0C up to 6 h. By further incubation for 24 h, glycoprotein\u20101, procarboxypeptidase A\u20101 and lipase were nearly completely degraded, while \u03b1\u2010amylase and procarboxypeptidase B\u20101 were not degraded under these conditions; \u03b1\u2010amylase became labile in the presence of 1 m<jats:sc>M<\/jats:sc> ethylene diaminetetraacetic acid (EDTA) or 10 m<jats:sc>M<\/jats:sc> phenyl methyl sulfonyl fluoride (PMSF). Protein degradation was observed by 2\u2010DE of an initial fraction of PPJ collected from patients with chronic calcific pancreatitis (CCP). The 2\u2010DE patterns of subsequent fractions resembled those of PPJ from healthy subjects. The mixture of the last fraction with the initial fraction showed significant protein degradation, inhibited by adding aprotinin. Furthermore, the extent of protein degradation correlated with the dilatation of the main pancreatic duct as a consequence of intraductal stagnation of pancreatic juice. These findings demonstrate that protein degradation in PPJ is accelerated by intraductal activation of serine proteases in the case of patients with CCP. 2\u2010DE of PPJ from patients with CCP provides useful information for the evaluation of intraductal activation of zymogens and the progress of chronic pancreatitis.<\/jats:p>","DOI":"10.1002\/elps.1150170430","type":"journal-article","created":{"date-parts":[[2005,5,28]],"date-time":"2005-05-28T11:11:10Z","timestamp":1117278670000},"page":"797-802","source":"Crossref","is-referenced-by-count":4,"title":["Protein degradation in human pure pancreatic juice analyzed by two\u2010dimensional gel electrophoresis"],"prefix":"10.1002","volume":"17","author":[{"given":"Toshifumi","family":"Furui","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miyuki","family":"Ikeda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liao","family":"Chao\u2010Ming","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiwamu","family":"Okita","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuyuki","family":"Nakamura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,4,14]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0009-8981(75)90105-9"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/000456328201900205"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0016-5085(91)90600-P"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.3109\/00365529309098248"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9258(19)41496-8"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/227680a0"},{"key":"e_1_2_1_8_2","doi-asserted-by":"crossref","first-page":"412","DOI":"10.1016\/S0016-5085(19)33072-0","volume":"65","author":"Allan B.
