Longitudinal Study of Transcriptomic Changes Occurring Over the Course of CHOP Treatment in Canine Lymphoma

The standard treatment for canine lymphoma (cL) is the CHOP chemotherapy protocol. Most cL patients treated with CHOP initially achieve remission but the duration varies and the majority of dogs eventually relapse with a multidrug resistant phenotype. This study assesses changes in gene expression occurring in cL tumor cell populations over the course of CHOP treatment. We measured gene expression using RNA-Seq on 15 cL patient samples taken prior to treatment and again 6 weeks into treatment. Overall design: Differential gene expression between canine lymphoma tumour samples from 15 dogs taken prior to treatment and 6 weeks into treatment. There were no replicate or control samples.
