abstract = {IntroductionAromatic (ar-) turmerone is a major bioactive
compound of the herb Curcuma longa. It has been suggested
that ar-turmerone inhibits microglia activation, a property
that may be useful in treating neurodegenerative disease.
Furthermore, the effects of ar-turmerone on neural stem
cells (NSCs) remain to be investigated.MethodsWe exposed
primary fetal rat NSCs to various concentrations of
ar-turmerone. Thereafter, cell proliferation and
differentiation potential were assessed. In vivo, naïve
rats were treated with a single intracerebroventricular
(i.c.v.) injection of ar-turmerone. Proliferative activity
of endogenous NSCs was assessed in vivo, by using
noninvasive positron emission tomography (PET) imaging and
the tracer [18F]-fluoro-L-thymidine ([18F]FLT), as well as
ex vivo.ResultsIn vitro, ar-turmerone increased
dose-dependently the number of cultured NSCs, because of an
increase in NSC proliferation (P < 0.01). Proliferation
data were supported by qPCR-data for Ki-67 mRNA. In vitro as
well as in vivo, ar-turmerone promoted neuronal
differentiation of NSCs. In vivo, after i.c.v. injection of
ar-turmerone, proliferating NSCs were mobilized from the
subventricular zone (SVZ) and the hippocampus of adult rats,
as demonstrated by both [18F]FLT-PET and histology
(P < 0.05).ConclusionsBoth in vitro and in vivo data
suggest that ar-turmerone induces NSC proliferation.
Ar-turmerone thus constitutes a promising candidate to
support regeneration in neurologic disease.},
