Definition: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: The aim of this study was to investigate the role of peroxiredoxin 1 (Prdx1) in the invasiveness of pancreatic ductal adenocarcinoma (PDAC) cells.', 'Immunohistochemistry was used to determine overexpression of Prdx1 in human PDAC tissues. Immunoprecipitation and immunocytochemistry were used to determine the interaction and intracellular distribution of Prdx1 and a member of the mitogen-activated protein kinase (MAPK) family protein, p38 MAPK, in PDAC cells. Finally, immunocytochemistry and Matrigel invasion assay were used to examine the effects of Prdx1 and p38 MAPK on the formation of cell protrusions and PDAC cell invasion.', 'Prdx1 is overexpressed in human PDAC tissues. Peroxiredoxin 1 interacts with active forms of p38 MAPK, and complexes of Prdx1 and phosphorylated p38 MAPK localize at the leading edges of migrating PDAC cells. Suppression of Prdx1 decreases active p38 MAPK localized in cell protrusions and inhibits the invasiveness of PDAC cells. Consequently, suppression of Prdx1 inhibits membrane ruffling and protrusions. The p38 MAPK inhibitor SB203580 also decreases the formation of membrane protrusions and inhibits invasiveness.
Output:
Does peroxiredoxin 1 promote pancreatic cancer cell invasion by modulating p38 MAPK activity?
