D-Tyr-tRNA(Tyr) deacylase, a new role in Alzheimer's-associated disease in SAMP8 mice.

Objective: To assess the expression level of D-Tyr-tRNA(Tyr) deacylase (DTD) in SAMP8 mice and speculate the function of DTD in disorders associated with Alzheimer's disease (AD).

Methods: Altogether 12 SAMP8 mice and 12 SAMR1 mice were used in this study. Semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were performed to detect the mRNA and protein levels of DTD in the mice.
