Directions: Put the following sentences in correct order to make up an abstract of a research paper. Abstract 1. We investigated p8 expression in 72 human pancreatic tissues, including 38 pancreatic cancers (PCs), by immunohistochemistry. 2. The p8 gene is a recently identified gene with mitogenic activity. 3. The p8 was over-expressed also in human pancreatic cancer lines (MIA PaCa-2 and PANC-1). 4. Its expression is induced in acute pancreatitis, pancreatic development, and regeneration. 5. The p8 was overexpressed (positive cells >25% in 1,000 cells) in 71% (27 of 38) of PCs, but in only 17% (3 of 18) of chronic pancreatitis cases. 6. However, the expression of p8 in pancreatic cancer is not reported. 7. There was no overexpression in mucinous cystadenoma or in normal pancreas. 8. The p8 overexpression rate in PC was significantly higher than that in other conditions (p<0.05). 9. These results suggest that p8 is involved in the development of pancreatic cancer, reflecting its mitogenic activity. 10. Reverse transcription-PCR analysis confirmed p8 mRNA overexpression (tumor/nontumor ratio >2) in 75% (3 of 4) of PCs.
