DRD2 and injury: Moreover, DRD2 signaling also modulated cell proliferation and modifies the pathology in a renal ischemia/reperfusion injury disease model, via its effects on Wnt/β‐catenin signaling, thus suggesting DRD2 as a transcriptional modulator of Wnt/β‐catenin signal transduction, with broad implications for health and development of new therapeutics (Han et al., 2019).
