Objective To investigate the effect of indomethacin on the protein expression profile of colorectal cancer cell line HCT116 xenografts in nude mice, and to screen the indomethacin anticancer-related proteins. Methods The nude mice with colorectal cancer cell line HCT116 xenograft were treated with or without indomethacin, and then the total proteins extracted from xenografts were separated and visualized by immobilized pH gradient two-dimensional gel (2-DE) electrophoresis. The differential expression proteins between the experimental and control groups were analyzed using PDQuest image analysis software, and identified by peptide mass fingerprinting based on matrix-assisted laser desorption ionization time of flight mass spectrometry and database searching. Results The 2-DE patterns with high resolution and reproducibility were obtained, displayed about 1100 protein spots in each gel, and the matching rate in the two groups was 96. 0% and 93. 6% , respectively. Thirty-one differentially expressed protein spots were found between the two groups, of which 25 spots decreased and 6 increased in the expression levels in the experimental group than in the control group. Eighteen peptide mass fingerprinting maps were obtained, and twelve proteins including galectin-1, annexin and trancription factor, were primarily identified after database searching, most of which were involved in tumor cell proliferation, invasion, apoptosis and immunity. Conclusions Indomethacin exerts its inhibiting effects on colorectal cancer through regulating multiple proteins expression directly or indirectly. The data will be helpful to elucidate the mechanism inhibiting cancer by indomethacin, and to find new targets of chemotherapeutic drugs.

Objective To investigate the residual functions in the hepatic lobe with deprivation of bile duct by observation of histomorphological and functional changes in the hepatic cells in a rat model. Methods The right hepatic bile ducts of rats were obstructed with cyanoacrylate and then ligated two weeks after the left and caudate lobes were removed. The lobus quadratus hepatis served as self-control with or without portal vein ligation. The venous blood from individualized liver lobe was examined and histological observation was done to examine the histomorphological and functional changes in the hepatic cells. Results Compared to the controls of both sham operation and untreated lobe, the hepatic lobe with bile ducts deprived did not undergo atrophy significantly with few ultrastructural changes. The hepatocytes of the hepatic lobe with bile duct deprived contained plenty of mitochondria, ribosomes and rough endoplasmic reticulum when observed under transmission electron microscope (TEM). The results of periodic acid-Schiff staining revealed normal glycogen metabolism in the hepatic cells. No significant decrease was detected in the serum albumin and fibrinogen concentrations by examination of blood collected from vein of this liver lobe with deprivation of bile ducts. Conclusions The liver lobes with bile ducts deprived retain most of the liver functions such as protein synthesis and nutrition metabolism, and show no atrophy during the observation period. It is suggested that the hepatic lobes with bile duct deprived still possess the value of preservation. The present study has founded a theoretic basis for remaining the remaining liver lobes with bile duct deprived or ligated in some emergency and specific clinical situations.
