The influence of recombinant interferon α2β synthesized in plants on the reparative enzyme mgmt expression in human somatic cells in vitro
[Free Full Text (pdf)] ![]() SUMMARY. The influence of recombinant interferon α2β synthe-sized in trasgenic plants on the expression of human repair protein O6-methylguanine-DNA methyltransfe-rase (MGMT) in both tumour and non-tumour ori-ginated cells was investigated. Human tumour Håp-2 cells (epidermoid carcinoma of the larynx) and non-tumour human E8 cells (originated in our laboratory from embrionic germ cells) were treated with purified recombinant interferon α2β in serum-free medium. Protein levels were determined by Western-blot method. Recombinant interferon α2β caused decrease in MGMT protein amount in tumour Håp-2 cells at all treated concentrations (2, 20, 200, 2000 IU/ml) relatively to the control level. In human non-tumour cells E8 we revealed a decrease in MGMT amount at two of the highest concentrations: 200 and 2000 IU/ml, although a statistically significant effect compared to the control level was observed only at a concentration of 200 IU/ml.
