Dronabinol 116-145 mitogen-activated protein kinase 1 Mus musculus 32-66 15857401-1 2005 We investigated the role of the Ras/extracellular-regulated kinase (ERK) pathway in the development of tolerance to Delta(9)-tetrahydrocannabinol (THC)-induced reduction in spontaneous locomotor activity by a genetic (Ras-specific guanine nucleotide exchange factor (Ras-GRF1) knock-out mice) and pharmacological approach. Dronabinol 116-145 mitogen-activated protein kinase 1 Mus musculus 68-71 15857401-1 2005 We investigated the role of the Ras/extracellular-regulated kinase (ERK) pathway in the development of tolerance to Delta(9)-tetrahydrocannabinol (THC)-induced reduction in spontaneous locomotor activity by a genetic (Ras-specific guanine nucleotide exchange factor (Ras-GRF1) knock-out mice) and pharmacological approach. Dronabinol 147-150 mitogen-activated protein kinase 1 Mus musculus 32-66 15857401-1 2005 We investigated the role of the Ras/extracellular-regulated kinase (ERK) pathway in the development of tolerance to Delta(9)-tetrahydrocannabinol (THC)-induced reduction in spontaneous locomotor activity by a genetic (Ras-specific guanine nucleotide exchange factor (Ras-GRF1) knock-out mice) and pharmacological approach. Dronabinol 147-150 mitogen-activated protein kinase 1 Mus musculus 68-71 15857401-3 2005 ), a specific inhibitor of mitogen-activated protein kinase kinase (MEK), the upstream kinase of ERK, fully prevented the development of tolerance to THC-induced hypolocomotion. Dronabinol 150-153 mitogen-activated protein kinase 1 Mus musculus 97-100 15857401-7 2005 These findings suggest that at least in the caudate putamen and cerebellum, the Ras/ERK pathway is essential for triggering the alteration in CB1 receptor function responsible for tolerance to THC-induced hypomotility.
