Description
A distinct type of macrophages helps breast cancer cells to overcome rate-limiting steps in the metastatic process and establish lethal metastatic tumors. Since only a minor population of cancer cells can establish macroscopic metastatic tumors, we hypothesized that this metastatic cancer cell population have higher expression of receptors for macrophage-derived ligands compared to their parental cells.

Description
ES cells are able to self-renew and remain pluripotent. These characteristics are maintained by both genetic and epigenetic regulators. Protein arginine methyltransferase (PRMT) 4 and 5 are shown to be important in early embryonic development and in ES cells. PRMT6-mediated di-methylation of histone H3 at arginine 2 (H3R2me2) can antagonize the tri-methylation of histone H3 at lysine 4, which marks active genes. However, it is unclear whether PRMT6 and PRMT6-mediated H3R2me2 play crucial roles in early embryonic development and ES cell identity. In this study, we investigate their functions using mouse ES cells as the model.

Description
Epithelial-mesenchymal transition (EMT) induced by microenvironment stimuli can be attributed to the transcriptional regulation of epithelial and mesenchymal phenotypes. Here we show how EMT is coordinated with cancer metabolism, an emerging hallmark of tumorigenesis.

Description
Purpose: The management of adrenocortical tumors (ACTs) is complex, compounded by the difficulty in discriminating benign from malignant tumors using conventional histology. The Weiss score is the current most widely used system for ACT diagnosis but it has limitations, particularly with ACTs with a score of 3. The am of this study was to identify molecular markers whose expression can discriminate adrenocortical carcinomas (ACCs) from adrenocortical adenomas (ACAs) by microarray gene expression profiling and to determine their clinical applicability by using immunohistochemistry (IHC). Experimental design: Microarray gene expression profiling was used to identify 7 molecular markers which were significantly differentially expressed between ACCs and ACAs. These results were confirmed with quantitative PCR for all 7 genes and IHC for 3 protein. Results: Microarray gene expression profiling was able to accurately categorize ACTs into ACCs and ACAs. All 7 genes were strong discriminators of ACCs from ACAs on qPCR. IHC with IGF2, MAD2L1, CCNB1 and Ki-67, but not ACADVL or ALOX15B, had high diagnostic accuracy in differentiating ACCs from ACAs. The best results however were obtained with a combination of IGF2 and Ki-67 with 96% sensitivity and 100% specificity in diagnosing ACCs. Conclusion: Microarray gene expression profiling accurately differentiates ACCs from ACAs. The combination of IGF2 and Ki-67 IHC is also highly accurate in distinguishing between the 2 groups and is particularly helpful in ACTs with Weiss score of 3.

Description
To investigate if biologically distinct subsets exists in extranodal NK/T-cell lymphoma (NKTL), we performed unsupervised integrative analyses of gene expression profiling (GEP), miRNA profiling, and copy number aberration (CNA) on 66 cases of NKTL from diverse anatomical sites. This series is the GEP data.

The hallmark of human cancer is heterogeneity, mirroring the complexity of genetic and epigenetic alterations acquired during oncogenesis. We extracted RNA of 34 cultured human ovarian carcinoma cell lines and performed expression microarrays so that cultured cell lines can represent in vivo human tumors.
