TranscriptomicsTranscriptomic response to benzo[a]pyrene treatment in HepG2 cells (RNA-Seq)
Whole-genome transcriptome measurements are pivotal for characterizing carcinogenic mechanisms of chemicals and predicting toxic classes, such as genotoxicity, from in vitro and in vivo assays. DNA microarrays have evolved as the gold standard for this purpose. In recent years deep sequencing techno...

TranscriptomicsComparison of hepatocarcinogen-induced gene expression profiles in conventional primary rat hepatocytes with in vivo rat liver
At present, substantial efforts are focused on the development of in vitro assays coupled with M-bM-^@M-^]omicsM-bM-^@M-^] technologies for the identification of carcinogenic substances as an alternative to the classical 2-year rodent carcinogenicity bioassay. A prerequisite for the eventual regulat...

TranscriptomicsExtensive temporal transcriptome and microRNA analyses identify molecular mechanisms underlying mitochondrial dysfunction induced by multi-walled carbon nanotubes in human lung cells (miRNA)
Understanding toxicity pathways of engineered nanomaterials (ENM) has recently been brought forward as a key step in 21st century ENM risk assessment. Molecular mechanisms linked to phenotypic end points is a step towards the development of toxicity tests based on key events, which may allow for gro...

TranscriptomicsTranscription profiling by array to identify Sex-Specific Transcriptome Responses to Polychlorinated Biphenyls (PCBs)
Blood samples were collected from adult volunteers at a time in the past when they were apparently healthy. Omics-based assays including gene expression were performed on blood samples from subjects who have since developed lymphoma or breast cancer, together with equal numbers of samples from match...

TranscriptomicsAnalysis of human enteroids and colonoids (3D organoid models from small intestine and colon) exposed to chemotherapy agent 5-fluorouracil (5FU) in a dose-repeated exposure across three doses (10,100 and 1000uM) and sampled at three points (24, 48 and 72h) since initial exposure. Organoids were obtained from healthy human tissues.
ADRs (adverse drug reactions) are one of the main reasons for treatment discontinuation or alterations in dose regimens in clinical settings. Chemotherapy-induced ADRs are common, especially gastrointestinal-induced ones. Within TransQST (transqst.org), one of the main goal is to improve the in vitr...
