Movement deficits and neuronal loss in basal ganglia in TRPC1 deficient mice.

In this study, we reported that TRPC1 deficiency caused movement disorder as measured by swimming test, modified open field test and sunflower seeds eating test. Immunofluorescent staining showed significant loss of both NeuN-positive cells and tyrosine hydroxylase (TH) -positive cells in the caudate putamen (CPu), the external globus pallidus (GPe), and the substantia nigra pars reticulata (SNr) in 5-month-old TRPC1 knockout mice (TRPC1-/-) compared to the wild type (WT) mice. TUNEL staining further revealed that TUNEL-positive cells were significantly increased in the CPu, GPe, and SNr of TRPC1-/- mice. Taken together, these data suggests that TRPC1 is involved in the control of motor function by inhibiting the apoptosis of neuronal cells of basal ganglia.
