Oxidative stress, i.e., excessive production of oxygen free radicals and reactive oxygen species, leads to lipid peroxidation and to formation of reactive aldehydes which act as second messengers of free radicals. It has previously been shown that oxidative stress may be involved in the transcriptional regulation of cytomegalovirus (CMV) immediate early promoter, involved in viral reactivation from latency. In the current study we used a plasmid containing the yellow fluorescent protein (YFP) gene under the control of CMV-1 promoter to monitor the influence of hydrogen peroxide and reactive aldehydes, 4-hydroxy-2-nonenal (HNE) and acrolein, on CMV-1 promoter activation in human embryonic kidney cells (HEK293). While acrolein was ineffective, hydrogen peroxide slightly (50 %) stimulated the CMV promoter. In contrast, HNE had a strong, up to 3-fold, enhancing effect on the CMV-1 promoter within four as well as after 24 h of treatment. The most effective was the treatment with 24 μM HNE. This effect of HNE suggests that stressful conditions associated with lipid peroxidation could lead to CMV activation.

Embryonic cells, when cultured at high density, are referred to as „micromass” cultures and can be used as a tool to predict the teratogenic potential of xenobiotics in screen test. The rate of proliferation and differentiation can easily be measured quantitatively by simple staining methods with subsequent spectrophotometry. However, reproducibility of the results can be influenced by variability of the technique. To adapt this method in our laboratory systematic series of experiments with limb bud cell cultures were undertaken. Inter-relationships between different variables were checked.

Malachite green (MG) consisting of green crystals with a metallic lustre, is very soluble in water and is highly cytotoxic to mammalian cells and also acts as a liver tumor promoter. In view of its industrial importance and possible exposure to human beings, MG poses a potential environmental health hazard. The malignant transformation of Syrian hamster embryo (SHE) cells by MG has been reported earlier. In this study, an attempt has been made to study the levels of vimentin, vimentin phosphorylation and the expression of PCNA and BrdU incorporation in MG transformed cells compared to control cells. Immunohistochemical and immunoprecipitation studies showed enhanced levels of vimentin in transformed cells compared to normal cells. Metabolic labelling studies showed an overall increase in phosphorylation of total cellular proteins as well as hyperphosphorylation of vimentin in transformed cells. Transformed cells also showed an increased doubling time, PCNA expression and BrdU incorporation. This study indicates a close relationship between vimentin levels, hyperphosphorylation of vimentin and increased cell proliferation associated with the malignant transformation of SHE cells.
