Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
For assessing the cancer-causing potential for humans of a chemical compound, the conventional approach is the use of the 2-year rodent carcinogenicity bioassay, thus alternatives such as in vitro toxicogenomics are highly desired. In the present study, the transcriptomics responses following exposure to genotoxic (GTX) and non-genotoxic (NGTX) hepatocarcinogens and non-carcinogens (NC) in five liver-based in vitro models, namely conventional and epigenetically-stabilized cultures of primary rat hepatocytes, the human hepatoma-derived HepaRG and HepG2 cell lines and the human embryonic stem cell-derived hepatocyte-like cells hES-Heps are examined and compared.
Publication Title
Transcriptomic responses generated by hepatocarcinogens in a battery of liver-based in vitro models.

Description
Patients with febrile malaria were recruited in order to determine Peripheral Blood Mononuclear Cell (PBMC) gene expression during malaria. Blood was harvested from patients during the acute phase of the illness, and then patients were given a curative regimen of antimalarials. Three to four weeks after treatment, patients returned to the malaria clinic and blood was collected again, in order that each patient could serve as his or her own control. PBMC were isolated at the time of blood collection and forzen in RNA extraction buffer. At the end of the study, each patient was arrayed for ~47,000 transcripts, comparing gene expression at the end of therapy to that at the beginning. The goal was to determine which genes were altered as a result of disease at least 2 fold in a statistically significant manner and to assess if the genes involved could be related to Toll-like receptor signaling pathways. Approximately 60 genes involved in inflammation were confirmed by qPCR.

Description
The precise molecular mechanism of action and targets through which thalidomide and related immunomodulatory drugs (IMiDs) exert their anti-tumor effects remains unclear. We investigated the role of cereblon (CRBN), a primary teratogenic target of thalidomide, in the anti-myeloma activity of IMiDs. CRBN depletion is initially cytotoxic to human myeloma cells but surviving cells with stable CRBN depletion become highly resistant to both lenalidomide and pomalidomide, but not to the unrelated drugs bortezomib, dexamethasone and melphalan. Acquired deletion of CRBN was found to be the primary genetic event differentiating isogenic MM1.S cell lines cultured to be sensitive or resistant to lenalidomide and pomalidomide. Gene expression changes induced by lenalidomide were dramatically suppressed in the presence of CRBN depletion further demonstrating that CRBN is required for lenalidomide activity. Downstream targets of CRBN include interferon regulatory factor 4 (IRF4) previously reported to also be a target of lenalidomide. Patients exposed to and putatively resistant to lenalidomide had lower CRBN levels in paired samples before and after therapy. In summary, CRBN is an essential requirement for IMiD activity, and a possible biomarker for the clinical assessment of anti-myeloma efficacy.

Description
Patients had low calorie diet weight reduction run in prior to the day of surgery. The human liver and subcutaneous fat tissue samples were obtained from 12 obese subjects undergoing bariatric surgery and then used for the mRNA expression analyses. Overall design: mRNA profiles of human liver and subcutaneous fat tissue samples were generated by RNA sequencing using Illumina HiSeq 2500.
