Objective To investigate the expression of CXC chemokine receptor 1 (CXCR1) and CXC chemokine receptor 2 (CXCR2) in triplenegative breast cancer (TNBC) and its significance.Methods The EnVision immunohistochemistry system was used to detect the expression of CXCR1 and CXCR2 in 28 specimens from normal tissues adjacent to breast cancer,30 specimens of invasive ductal carcinoma not otherwise specified (IDC-NOS),and 34 TNBC specimens.The relationship between the expression of CXCR1 and CXCR2,and clinical pathological features was analyzed.Results In the adjacent normal tissues of breast cancer,the positive expression rates of CXCR 1 and CXCR2 were 89.3％ and 92.9％,respectively;CXCR1 and CXCR2 expression displayed no significant association with clinicopathological parameters such as age,tumor size,or Scarff-Bloom-Richardson (SBR) score.The positive expression rates of CXCR1 and CXCR2 were 63.3％ and 60.0％,respectively,in the IDC-NOS samples and 23.5％ and 35.3％,respectively,in the TNBC samples.There was a positive correlation between CXCR1 and CXCR2 expression in the TNBC samples (r =0.606,P ＜ 0.001).Conclusion Correlation of CXCR1 and CXCR2 expression with sample type was strong in adjacent normal tissues,moderate in IDC-NOS samples,and low in TNBC samples.CXCR1 expression was positively correlated with CXCR2 expression in all sample types.The expression of CXCR1 or CXCR2 was closely related to the development and promotion of TNBC.

The mammalian liver has a very strong regeneration capacity after partial hepatectomy (PH). To further learn the genes participating in the liver regeneration (LR), 551 cDNAs selected from subtracted cDNA libraries of the regenerating rat liver were screened by microarray, and their expression profiles were studied by cluster and generalization analyses. Among them, 177 genes were identified unreported and up- or down-regulated more than twofold at one or more time points after PH, of which 62 genes were down-regulated to less than 0.5; 99 genes were up-regulated to 2-10 folds, and 16 genes were either up- or down-regulated at different time points during LR. By using BLAST and GENSCAN, these genes were located on responsible chromosomes with 131 genes on the long arms of the chromosomes. The cluster and generalization analyses showed that the gene expression profiles are similar in 2 and 4, 12 and 16, 96 and 144 h respectively after PH, suggesting that the actions of the genes expressed in the same profiles are similar, and those expressed in different profiles have less similarity. However, the types, characteristics and functions of the 177 genes remain to be further studied.
