'These publicly accessible databases aim to provide an overview of all animal studies (including those that are ongoing and work that may remain unpublished) to increase transparency and reduce unnecessary duplication of experiments. Unfortunately, usage to date has been low, with only a few hundred entries across each registry [7]. As a potential solution, we propose integrating preclinical registration within the animal use protocol (AUP) review process'
