In vivo monitoring of recovery from neurodegeneration in conditional transgenic SCA1 mice.

ABSTRACT: Reliable and objective markers of neuronal function and pathology that can directly assess the effects of neuroprotective treatments in the brain are urgently needed for clinical trials in neurodegenerative diseases. Here we assessed the sensitivity of high field proton magnetic resonance spectroscopy ((1)H MRS) to monitor reversal of neurodegeneration by taking advantage of a well characterized conditional mouse model of spinocerebellar ataxia type 1 (SCA1), where the cerebellar pathology and ataxic phenotype are reversible by doxycycline administration. Transgene expression was suppressed by feeding the mice with chow that contains doxycycline from 6 to 12 weeks of age in an early stage group and from 12 to 24 weeks in a mid-stage group. Cerebellar neurochemical profiles of treated and u
