Transporter proteins implicated in neuropathy development induced by oxaliplatin and paclitaxel have been identified (Huang et al., 2020; Leblanc et al., 2018; Sprowl et al., 2016); even so, the specific transporter proteins contributing to BTZ accumulation in the DRG remain unclear (Stage et al., 2021). The gene discussed is CASC3; the disease is neuropathy.
