Fig. 5. TRESK transcript expression increased in the dorsal horn of spinal cord of SNL rats. Quantitative real-time PCR of TRESK gene expression in the ipsilateral L5-6 spinal cord at 0, 7, 14, 21, and 28 days after SNL. Data are presented as the fold change from the control (naïve) mean±SEM, which represented normalized averages derived from the threshold cycles in 6 to 8 ipsilateral samples. ^*p<0.05 vs. control, ^†p<0.01 vs. control. TRESK, TWIK-related spinal cord K⁺; SNL, spinal nerve ligation; PCR, polymerase chain reaction.
