Integration of single‐cell and bulk RNA‐sequencing data reveals the prognostic potential of epithelial gene markers for prostate cancer

open access: yesMolecular Oncology, EarlyView.
Prostate cancer is a leading malignancy with significant clinical heterogeneity in men. An 11‐gene signature derived from dysregulated epithelial cell markers effectively predicted biochemical recurrence‐free survival in patients who underwent radical surgery or radiotherapy.

Stochastic dynamics of three competing clones: Conditions and times for invasion, coexistence and fixation [PDF]

open access: yesarXiv, 2016
In large clonal populations, several clones generally compete which results in complex evolutionary and ecological dynamics: experiments show successive selective sweeps of favorable mutations as well as long-term coexistence of multiple clonal strains.

Population genetics of multigene families that are dispersed into two or more chromosomes.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1983
The evolution of multigene families whose members are dispersed into two or more nonhomologous chromosomes is studied from the standpoint of population genetics.

Clinical significance of stratifying prostate cancer patients through specific circulating genes

open access: yesMolecular Oncology, EarlyView.
We tested a specific panel of genes representative of luminal, neuroendocrine and stem‐like cells in the blood of prostate cancer patients, showing predictive value from diagnosis to late stages of disease. This approach allows monitoring of treatment responses and outcomes at specific time points in trajectories.

Non-Mendelian Single-Nucleotide Polymorphism Inheritance and Atypical Meiotic Configurations are Prevalent in Hop

open access: yesThe Plant Genome, 2017
Hop ( L.) breeding programs seek to exploit genetic resources for bitter flavor, aroma, and disease resistance. However, these efforts have been thwarted by segregation distortion including female-biased sex ratios.

The fixation probability of rare mutators in finite asexual populations

open access: yes, 2008
A mutator is an allele that increases the mutation rate throughout the genome by disrupting some aspect of DNA replication or repair. Mutators that increase the mutation rate by the order of 100 fold have been observed to spontaneously emerge and achieve

1 Understanding Gene Duplication Through Biochemistry and Population Genetics

open access: yes, 2011
Gene duplication has emerged as an important process supporting the functional diversification of genes. Since publication of the seminal book Evolution by Gene Duplication by Ohno (1970), the hypothesis regarding the importance of gene duplication in ...

SUBSTITUTION PROCESSES IN MOLECULAR EVOLUTION. II. EXCHANGEABLE MODELS FROM POPULATION GENETICS

open access: yesEvolution; international journal of organic evolution, 1994
Substitution processes are of two sorts: origination processes record the times at which nucleotide mutations that ultimately fix in the population first appear, and fixation processes record the times at which they actually fix.

Response to neoadjuvant chemotherapy in early breast cancers is associated with epithelial–mesenchymal transition and tumor‐infiltrating lymphocytes

open access: yesMolecular Oncology, EarlyView.
Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

Loss and Recovery of Genetic Diversity in Adapting Populations of HIV [PDF]

open access: yesarXiv, 2013
The evolution of drug resistance in HIV occurs by the fixation of specific, well-known, drug-resistance mutations, but the underlying population genetic processes are not well understood. By analyzing within-patient longitudinal sequence data, we make four observations that shed a light on the underlying processes and allow us infer the short-term ...
