Chronic DHM and PRE-084 hydrochloride treatment attenuated the development of PD-like motor functions in Dicer cKO mice. All mice were injected with 10 mg/mL tamoxifen (i.p.) twice a day for 5 days. Meanwhile, mice also received daily injections of 10 mg/kg of DHM, 1 mg/kg of PRE-084 hydrochloride, or vehicle, respectively, for 8 weeks. Behavioral tests were conducted every other week starting from week 6. The pole test and rotarod test were performed in mice at indicated times with or without DHM and PRE-084 hydrochloride injections, respectively.
