Modeling stochastic clonal interference
We study the competition between several advantageous mutants in an asexual population (clonal interference) as a function of the time between the appearance of the mutants ∆t, their selective advantages, and the rate of deleterious mutations. We find that the overall probability of fixation (the probability that at least one of the mutants becomes the ancestor of the entire population) does no...
متن کاملStudy on the Biological Characteristics of CD133+ Cells Interfered by RNA Interference in Gastric Cancer
Background. To detect the changes of biological characteristics in gastric cancer cells interfered by CD133-specific small interfering RNA (siRNA). Methods. First to select the siRNA which has the strongest interference effect among 3 siRNAs (i.e., siRNA1, siRNA2, and siRNA3) in KATO-III cells by RT-PCR and Western blotting assays. Then, CD133(+) cells were sorted out from KATO-III cells using ...
متن کاملClonal interference in large populations.
Clonal interference, the competition between lineages arising from different beneficial mutations in an asexually reproducing population, is an important factor determining the tempo and mode of microbial adaptation. The standard theory of this phenomenon neglects the occurrence of multiple mutations as well as the correlation between loss by genetic drift and clonal competition, which is quest...
متن کاملClonal heterogeneity of lymphoid malignancies correlates with poor prognosis
Clonal heterogeneity in lymphoid malignancies has been recently reported in adult T-cell lymphoma/leukemia, peripheral T-cell lymphoma, not otherwise specified, and mantle cell lymphoma. Our analysis was extended to other types of lymphoma including marginal zone lymphoma, follicular lymphoma and diffuse large B-cell lymphoma. To determine the presence of clonal heterogeneity, 332 cases were ex...
متن کاملClonal Interference in the Evolution of Influenza
The seasonal influenza A virus undergoes rapid evolution to escape human immune response. Adaptive changes occur primarily in antigenic epitopes, the antibody-binding domains of the viral hemagglutinin. This process involves recurrent selective sweeps, in which clusters of simultaneous nucleotide fixations in the hemagglutinin coding sequence are observed about every 4 years. Here, we show that...
