View SamplesHuman NK cells were sorted into CD56dim and CD56bright NK cell subpopulations. In order to define characteristics of both populations gene profiling was performed using Affymetrix arrays U133a and U133B.
Gene and protein characteristics reflect functional diversity of CD56dim and CD56bright NK cells.

View SamplesReconstitution of cell lines and occurrence of complications following hematopoietic stem cell transplantation (HSCT) are regulated by genome expression. Microarray technique allows for simultaneous assessment of expression of nearly all human genes. The objective of the study was to compare whole genome expression in children before and after HSCT. A total of 44 children treated with HSCT were enrolled in the study. Gene expression was measured before HSCT (pre-HSCT group; n=44) and after a median of 6 months after allogenic HSCT (post-HSCT group; n=27; all children were included in the pre-HSCT group). Neoplasms were the indication for HSCT in 73% of the patients. Whole genome expression was assessed in leukocytes using GeneChip HumanGene 1.0 ST microarray. The analysis of genomic profiles before and after HSCT revealed 18 significantly different genes with defined function. These genes are responsible for proliferation and differentiation of cells (14 genes), apoptosis (8 genes), migration of cells (3 genes) and fluid/electrolyte homeostasis (2 genes). Our findings allow us to conclude that activation of genes involved in reconstitution of donor cell lines, and those related to immune reactions observed after HSCT, form the genetic background for physiological and pathological processes following HSCT.

View SamplesClear cell renal cell carcinoma is the most common type among kidney cancers, accounting for 80% of all kidney cancer cases and over 30% of patients have metastases at the time disease is diagnosed. The process od epithelial-mesenchymal transition is crucial for the development and progression of cancer, and here we wanted to check the expression of genes on different stages of tumor progression, and find which of them changes significantly with increased grade.

View SamplesMice expressing luciferase and GFP under control of the FoxP3 promoter were treated with either the DR3 agonist antibody 4C12 or the DR3 agonist fusion protein TL1A-Ig with low-dose IL-2 (or isotype control antibody), regulatory T cells were sorted from spleens on day 7, and bulk RNA sequencing was performed.

View SamplesIn the current study, we investigated the collective roles of protein tyrosine phosphatases (PTPs) and histone deacetylases (HDACs) on regulation of IRG expression in human choriocarcinoma cells by genome-wide transcriptional profiling. Logic-rules were optimized to derive rules governing gene expression patterns observed upon different combinations of treatment with PTP and HDAC inhibitors. The data reveal that IRGs can be divided into distinct subsets that are differentially modulated by co-treatment of Jar cells with IFN-? and PTP versus HDAC inhibitors, respectively. Furthermore, promoter analysis of the genes governed by the rules identifies transcription factor binding sites associated with the different gene subsets. Thus, the regulatory modes identified in this study provide insights into the complex regulation of inflammatory pathways at the fetal-maternal interface, as well as mechanisms that choriocarcinoma cells may utilize to promote their survival.
