Description
Treatment of cancer cells with anti-cancer drugs often fails to achieve complete remission. Yet, such drug treatments may induce alteration in the tumor’s gene expression patterns, including those of Cancer/Testis Antigens (CTA). The degradation products of such antigens can be presented as HLA peptides on the surface of the tumor cells and be developed into anti-cancer immunotherapeutics. For example, the DNA methyl transferase inhibitor, 5-aza-2''-deoxycytidine (Decitabine) has limited anti-tumor efficacy, yet it induces the expression of many genes, including CTAs that are normally silenced in the healthy adult tissues. In this study, the presentation of many new HLA peptides derived from CTAs and induced by Decitabine was demonstrated in three human Glioblastoma cell lines. Such presentation of CTA-derived HLA peptides can be exploited for development of new treatment modalities, combining drug treatment with anti-CTA targeted immunotherapy. The Decitabine-induced HLA peptidomes include many CTAs that are not normally detected in healthy tissues or in cancer cells, unless treated with the drug. In addition, the study included large-scale analyses of the simultaneous effects of Decitabine on the transcriptomes, proteomes and HLA peptidomes of the human Glioblastoma cells. It demonstrates the poor correlations between these three levels of gene expression, both in their total levels and in their response to the drug. Overall design: The transcriptomes, proteomes and HLA peptidomes of the U-87, T98G and LNT-229 GBM human cell lines were analyzed before and after treatment with Decitabine. Overall, the RNA-Seq transcriptome analyses resulted in the identification of above 26000 transcripts, the proteome analyses identified about 7500 proteins and the HLA class I peptidome analyses resulted in above 25000 identified HLA peptides. Two biological repetitions of the transcriptome, three of the proteome and three of the HLA peptidome were performed with each of the cell lines and treatment, resulting in highly reproducible datasets.

Affymetrix Mouse Expression 430A Array (moe430a)
Description
The arylhydrocarbon receptor is a ligand inducible transcription factor. Known to control xenobiotic metabolizing enzymes, it also affects - depending on the cell type - numerous other genes, either directly or indirectly. With respect to the immune system, persistent activation leads to immunosuppression. We asked how the AhR is involved in Langerhans cells. These antigen presenting cells of the skin are responsible for allergies against chemicals (thus xenobiotic metabolism might be relevant) and a recently detected endogenous ligand, FICZ made by UVB radiation from tryptophane, is particularly abundant in the skin.

Description
Young individuals possess distinct properties that adults do not. The juvenile animals show higher activities for growth, healing, learning and plasticity than adults. The machinery for establishing these juvenile properties is not fully understood. To better understand the molecular constituents for the above properties, we performed a comprehensive transcriptome analysis of differently aged cells of mice by high-throughput sequencing. The samples are isolated mouse hepatocytes and caridomyocytes in triplicate. As a result, we identified the genes selectively highly expressed in the young cells. These genes, collectively called as juvenility-associated genes (JAGs), show significant enrichments in the functions such as alternative splicing, phosphorylation and extracellular matrix (ECM). This implies the juvenescence might be achieved by these functions at the cell level. The JAG mutations are associated with progeria syndromes and growth disorders. Thus, the JAGs might organize the juvenile property of young animals and analysis of JAGs may provide scientific and therapeutic approaches toward treating the genetic diseases.

Description
In the present study we investigate the role of IL-4 receptor a subunit in intestinal inflammation using DSS-induced colitis model. Our finding suggest that IL-4Ra deficiency enhances intestinal mucosal barrier function through the upregulation of NOX1-dependent ROS production, thereby suppressing the development of intestinal inflammation.

Description
In humans, the embryonic genome activation (EGA) program is functional by day 3 after fertilization. The 6-8 cell stage embryo (day 3 post-fertilization) starts the process of compaction that leads to the generation of the tightly organized cell mass of the morula and is followed by differentiation of the morula into a blastocyst. The transition from day 3 embryos to day 5 blastocysts is likely to be controlled by many and specific changes in the expression of different genes. We used mRNA amplification technique and compared the transcriptomes of day 3 human embryos and trophectoderm (TE) cells from day 5 human blastocysts to identify transcripts that are differentially expressed during the embryo-to-TE transition and involved in the TE specification.
Publication Title
Transcriptome analysis during human trophectoderm specification suggests new roles of metabolic and epigenetic genes.
