Objectives:
The effect of geldanamycin (GA) on the brain is poorly understood. The induction of specific heat shock protein (HSP) isoforms by GA has not been studied in detail. The aim of this work was to identify the HSP70 genes that become up-regulated in the mouse brain after GA administration.
Methods:
The brains of male hsp 70.1 knockout and littermate mice were obtained after GA injection into the lateral ventricle. The mice were killed 6 hours later to investigate the levels of hsp 70.1 and hsp 70.3 using semi-quantitative reverse transcriptase polymerase chain reactions.
Results:
GA infusion into the mouse brain led to the up-regulation of hsp 70.1.
Discussion:
Further work is needed to more clearly define the role of those genes in the clinical effects of GA.
