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.
