Application | Comment | Organism |
---|---|---|
drug development | RX-3117, an orally available cytidine analogue, is activated by UCK2 which may be used to select patients potentially sensitive to RX-3117 | Homo sapiens |
Protein Variants | Comment | Organism |
---|---|---|
additional information | enzyme silencing by transfection of A549 and SW1573 cell lines with UCK-siRNAs. Transfection of UCK1-siRNA efficiently downregulates UCK1-mRNA, but not UCK2-mRNA expression, and does not affect sensitivity to RX-3117. Transfection of UCK2-siRNA completely downregulates UCK2-mRNA and protein and protects both A549 and SW1573 against RX-3117 | Homo sapiens |
