WebInvestigating whether CH could be used as a prognostic biomarker for patients with bladder cancer found that detection of CH may provide crucial prognostic information about tumor recurrence in bladder cancer. Purpose: Recent studies have reported that centrosome hyperamplification (CH) is closely related to chromosomal instability in bladder cancer. … WebComplex inverted structures promote hyper-amplification process and shape amplicon structures in response to genetic selection. IRs are a potent trigger for the formation of dicentric chromosomes that can initiate BFB cycles, and thereafter hyper-amplification by RCR requires a direct repeat on the dicentric chromosome.
