The expression of hTERT, c-myc, PPARγ, cyclin D and bcl-2 genes over 12 h (hours) in normal human PBMCs treated with growth medium containing 10% NHS and 2.5 mM EGTA. The cells were harvested at indicated time points and subjected to RT-PCR and western blotting. (A) Representative agarose gel photographs showing ethidium bromide stained RT-PCR products of hTERT, c-myc, PPARγ and β2M genes. (B) Graph showing the changes in mRNA levels of hTERT, c-myc and PPARγ genes with increasing time after EGTA treatment. The relative levels of hTERT, c-myc and PPARγ mRNA expression were determined by measuring their band intensities using SCION IMAGE analysis software and normalizing to β2M band intensity. Data are expressed as percentage of control (0 h). Each data point represents mean ± SD of three independent experiments. (C) Western blot analysis of expression of cyclin D and bcl-2 proteins. Equal amount of protein was used for the four samples. The western blot shown is a representative of three independent experiments.
