Analysis of mid-colon and mid-jejunum segments from C57BL/6J wild-type mice exposed to 5-fluorouracil (5-FU). Intravenous exposure to 5-FU was performed with two doses (20 and 50 mg/kg), over a period of 4 days. Mucosal scrapes samples were collected for RNA isolation at 6, 24 and 96h since initial exposure. A recovery period of 2 days (sampled at 144h) followed up the 96h of repeated exposure. Samples from time-matched controls (saline 10 mM Tris/NaOH buffer pH 8.5) were also quantified.

ABSTRACT: 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 vitro-in vivo translation in toxicological studies, as well as translation between non-clinical species (such as rat and mouse) and humans. This experimental setup aimed to investigate the injury dynamics underlying repeated exposure to two doses of 5-FU (20 and 50 mg/kg), sampled at multiple time points (6, 24, 96 and 144h). The 144h time point comprises of recovery samples (i.e., 48h following the last dosing with 5-FU). This dataset is part of the TransQST collection.

RNA-seq of human colon biopsy tissue of healthy segments, from advanced breast cancer patients treated with capecitabine (5-FU)

Project description: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 vitro-in vivo translation in toxicological studies, as well as translation between non-clinical species (such as rat and mouse) and humans. This experimental setup therefore aimed to investigate the effects of capecitabine, which is activated into 5-FU in the body, on advanced breast cancer patients. Healthy colon tissue was collected from the patients before and after the first cycle of the monotherapy, which consists of 2 weeks treatment followed by 1 week rest. Each patient was their own control sample. Transcriptomic data collected from the colon biopsies was compared with previous data collected from colon organoids to verify for the translatability of the in vitro model to humans. This dataset is part of the TransQST collaboration.

Analysis of mid-colon and mid-jejunum segments from C57BL/6J wild-type mice exposed to doxorubicin (DOX)

Project description: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 vitro-in vivo translation in toxicological studies, as well as translation between non-clinical species (such as rat and mouse) and humans. This experimental setup therefore aimed to investigate the effects of DOX on mouse tissue derived from colon and jejunum biopsies. Experiments were conducted in a dose (5 and 10 mg/kg) and time series regimen (6, 24, 72 and 96h). Time-matched controls were measured as well. Intravenous exposure to DOX was performed with two doses (5 and 10 mg/kg), over a period of 4 days. Mucosal scrapes samples were collected for RNA isolation at 6, 24, 72 and 96h since initial exposure. Samples from time-matched controls (saline 10 mM Tris/NaOH buffer pH 8.5) were also quantified.
