Dopamine-sensitive adenylate cyclase activity in the striatum in Parkinson's disease. 1979

M Shibuya

Dopamine (DA) sensitive adenylate cyclase activity was measured in homogenates of caudate nucleus and putamen from frozen brain of eight Parkinsonian patients and nine controls. In the control group, there was no difference in enzyme activity in respect to sex or age (21--77 years old). Caudate nucleus and putamen exhibited similar mean activity. In the Parkinsonian group, there was a significant decrease in both basal (by 50%) and DA stimulated (by 80%) activities compared with that of control group. This suggests that there may exist a functional disturbance in the postsynaptic (post-DA-nergic) region in the striatum of patients with Parkinson's disease; in addition, the decrease in basal as well as DA stimulated activity as measured in homogenates may not be the biochemical substrate for the hypothetical "denervation supersensitivity" expected to occur in Parkinson's disease.

UI MeSH Term Description Entries
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010300 Parkinson Disease A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

D004298 Dopamine One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
