Expression profiles of IGnT genes in K-562 cells expressing wild-type and mutant C/EBPα. Wild-type C/EBPα and C/EBPα mutants with respective substitutions of S21A, S21D, S234A, and S234D were expressed in K-562 cells cultured in noninducing conditions. Real-time PCR was used to quantify the IGnTA, IGnTB, IGnTC, and GAPDH transcripts in the cDNA samples. The quantities of the IGnT transcripts were normalized to that of GAPDH transcript in each sample. Data were obtained from 3 detections; SDs are shown.
