As a result, many of these micro VC funds which don't have the multiple hits required to survive, will by contrast, die a slow death.
Second, hprt mutations arise preferentially in dividing T-cells, which can accumulate additional mutations in the same clone, reminiscent of the multiple hits required in the evolution of malignancy.
It performs gapped alignment for single-end reads, supports paired-end mapping, generates mapping quality and gives multiple hits if required.
It may be that methylation levels are generally well conserved following a duplication event because such "multiple hits" are required to substantially remodel the methylation levels at a region.
This concept proposes that redundant mechanisms are available to bring about normal repolarization; therefore, to elicit the full-blown LQTS phenotype multiple hits might be required to sufficiently reduce the reserve (Roden, 2006).
Focusing on epigenetic regulators, we identified WDR5, a core member of the COMPASS histone H3 Lys4 (H3K4) MLL (1 4) methyltransferase complex, as a top tumor maintenance hit required across multiple human and mouse tumors.
Since multiple "hits" are thought to be required for malignant transformation [ 67], it might be advantageous for a tissue to minimize the number of cells that carry two or more mutations [ 11, 68], even if that came at the cost of an overall increase in mutation frequency.
Even in individuals with multiple genetic/acquired risk factors, aHUS may not occur until adulthood, indicating that a triggering event that activates the alternative pathway is required for disease manifestation in genetically susceptible individuals (the multiple hits theory).
Lastly, as EMS may produce multiple hits in the gene of interest [ 20], verifying the mutation responsible for the scored phenotype requires laborious complementation tests or full-genome sequencing.
Effects will be due to "multiple hits" of environmental exposures and may occur only after a latent period of months to decades, requiring a lifespan research approach, including prospective human studies.
We estimate with confidence that: Effects will be due to "multiple hits" of environmental exposures and may occur only after a latent period of months to decades, requiring a lifespan research approach, including prospective human studies.
