DISRUPTION OF EXPRESSION OF MRNA HSP27 AND UBIQUITIN AS A MECHANISM OF ESCAPING OF JURKAT LINE TUMOR CELLS FROM APOTOSIS

The research objective is to establish the link between heat shock protein 27 and ubiquitin mRNA expression as well as Jukart tumor cell apoptosis. The method of flow cytofluorometry has been used to evaluate apoptosis realization using FITC-labeled annexin V and propidium iodide along with the amount of reactive oxygen species. Spectrofluorimetry has been applied to register the caspase-3 activity. The content of hydroxyl radicals has been determined by spectrophotometry. The level of ubiquitin and heat shock protein 27 mRNA expression has been identified using real-time PCR. Intact Jukart tumor cells and blood lymphocytes of healthy donors served the material for the research. Following the carried out research it has been found out that the fall in the amount of annexin V positive cells and the reduced caspase-3 activity were accompanied by the rise in the content of hydroxyl radicals and reactive oxygen species against the backdrop of the increased heat shock protein 27 and ubiquitin mRNA expression in Jukart tumor cells.
