For many years, DNA gyrase was thought to be responsible both for unlinking replicated daughter chromosomes and for controlling negative superhelical tension in bacterial DNA. However, in 1990 a homolog of gyrase, topoisomerase IV, that had a potent decatenating activity was discovered. It is now clear that topoisomerase IV, rather than gyrase, is(More)
Antibacterial activities of gatifloxacin (AM1155), a new C-8-methoxy fluoroquinolone, and two structurally related compounds, AM1121 and ciprofloxacin, were studied with an isogenic set of ten quinolone-resistant, gyrA (gyrase) mutants of Escherichia coli. To compare the effect of each mutation on resistance, the mutant responses were normalized to those of(More)
Studies have shown that homeobox D10 (HOXD10) is the target gene of microRNA-10b (miR-10b) and is closely associated with the inhibition of cell migration and invasion. Ras homolog family member C (RhoC) has been reported to promote tumor metastasis in various types of cancer. The effect of miR-10b on colorectal cancer (CRC) metastasis and the associated(More)
