Gene expression pattern after insertion of dexamethasone-eluting electrode into the guinea pig cochlea.

Project description:To investigate the effect of the dexamethasone-eluting electrode in the guinea pig cochlea, and compared the gene expression after 7 days insertion with that of a normal electrode or non-treated control by microarray. Male Hartley guinea pigs (SLC, Shizuoka, Japan) with an age of seven weeks were used for the study. Three were implanted with normal electrodes while three others received a dexamethasone-eluting electrode. The cochleae from two animals, which did not undergo surgery. Seven days after electrode implantation the whole temporal bone was removed and placed into RNAlater solution (Ambion, Life Technologies Co., Grand Island, NY) to stabilize and protect cellular RNA. The whole cochlea was dissected out under a microscope and total RNA were extracted.

Gene expression pattern after insertion of dexamethasone-eluting electrode into the guinea pig cochlea.

Project description:A cochlear implant is an indispensable apparatus for a profound hearing loss patient. But insertion of the electrode entails a great deal of stress to the cochlea, and may cause irreversible damage to hair cells and related nerve structure. Although damage prevention effects of dexamethasone have been reported, long-term administration is difficult. In this study, we used a dexamethasone-eluting electrode in the guinea pig cochlea, and compared the gene expression after 7 days insertion with that of a normal electrode and non-surgically treated control by microarray. 40 genes were up-regulated 2-fold or more in the normal electrode group compared to the non-surgically treated group. Most of the up-regulated genes were associated with immune response and inflammation. In the dexamethasone-eluting group, compared to the normal electrode group, 7 of the 40 genes were further up-regulated, while 12 of them were down-regulated and there was a tendency to return to the non-surgical condition. 9 genes were down-regulated 2-fold or less with normal electrode insertion, and 4 of the 9 tended to return to the non-surgical condition in the dexamethasone-eluting group. These genes are certainly involved in the maintenance of the physiological functions of the cochlea. Our results indicate that the dexamethasone-eluting electrode will have an effect on the normalization of homeostasis in the cochlea.
