  1. Data indicate the ratios of 2-ΔCT values of corresponding gene pairs. The ratios were calculated by dividing the greater value with the smaller one so as to get quotients exceeding 1. CT values were determined by calculating the means of three parallel PCR amplifications from three independent cDNA samples (N = 9) prepared from SK-NF-I cultures kept for 8 hrs in 1% hypoxia.
