Increased level of Oct-1 protein in tumor cells modulates cellular response to anticancer drugs

Аннотация

The effect of overexpression of Oct-1 protein isoforms on the cell response to two anticancer drugs camptothecin and dexamethasone was studied. The effect of Oct-1 isoforms on regulated gene transcription was estimated by the difference in the level of mRNA in Burkitt’s lymphoma cells (Namalwa line) untransfected and stably transfected with Oct-1 isoforms. The response to anticancer drugs of the Oct-1 target genes involved in the development of apoptosis depended, firstly, on the type of drug, secondly, on the concentration of Oct-1 in cells. and, thirdly, on the Oct-1 isoform with which these cells were transfected.
