Expression of choline acetyltransferase mRNA in T-lymphocytes.

[Effect of acupuncture on the expression of choline acetyltransferase mRNA in the brain of ovarietomized rats].

The purpose of the present study was to investigate the mechanism of the effect of estrogen on the production of acetylcholine in the brain and to study the regulatory role of acupuncture of Zusanli acupoint in acetylcholine production in the brain of ovariectomized rats. Experimental female Wistar rats were divided into three groups: intact group (INT), ovariectomized group (OVX), and ovariect...

Developmental and regional expression of choline acetyltransferase mRNA in the rat central nervous system.

The developmental and regional expression of choline acetyltransferase (ChAT) mRNA was examined in the rat brain and spinal cord by northern blot analysis and in situ hybridization. ChAT mRNA expression in the brain showed a biphasic increase during development, with a first peak at two weeks postnatally, a marked decrease by the third week, and a second increase between the third and fifth wee...

Choline transporter 1 maintains cholinergic function in choline acetyltransferase haploinsufficiency.

Choline acetyltransferase (ChAT), the enzyme that synthesizes the neurotransmitter acetylcholine (ACh), is thought to be present in kinetic excess in cholinergic neurons. The rate-limiting factor in ACh production is the provision of choline to ChAT. Cholinergic neurons are relatively unique in their expression of the choline transporter 1 (CHT1), which exhibits high-affinity for choline and ca...

Detection of leptin and leptin receptor mRNA expression in the bovine t

Choline acetyltransferase from rat brain.

The localization, purification, and some enzymatic properties of choline acetyltransferase from rat brain were studied. Most assays were performed with a specific radiometric micromethod. Solubilization of the enzyme was examined after homogenization of cerebral cortices by means which disintegrate nerve endings. In isotonic KC1 the enzyme was recovered in solution. In more dilute KC1 the enzym...
