Summary
Thioredoxin (Trx) is a multifunctional protein with a redox-active disulfide/dithiol in the active site. Thioredoxin, with its redox-regulating and reactive oxygen species (ROS) scavenging activities, plays several important biologic roles both in intracellular and extracellular compartments. The purpose of this report was to quantify the relative expression of Trx in rat hippocampus following an oxidative stress-involving treatment such as kainic acid (KA) using real-time PCR and the 2(T)(-DeltaDeltaC) method. The relative changes in expression of Trx mRNA in KA-treated and control animals were significantly different as 2.02 +/- 0.77 and 1.0 +/- 0.26, respectively (P < 0.05). Minimum and maximum n-fold changes in Trx expression in KA-treated and control animals were determined as (1.4-5.2) and (0.8-1.3), respectively. Thus, real-time PCR and the 2(T)(-DeltaDeltaC) method for data analysis from real-time PCR were found to be an accurate and sensitive method for quantifying Trx mRNA levels.
