The Population Genetics of Clonal and Partially Clonal Diploids [PDF]

open access: yesGenetics, 2003
Abstract The consequences of variable rates of clonal reproduction on the population genetics of neutral markers are explored in diploid organisms within a subdivided population (island model). We use both analytical and stochastic simulation approaches. High rates of clonal reproduction will positively affect heterozygosity.

Impact of CMV Infection on Natural Killer Cell Clonal Repertoire in CMV-Naïve Rhesus Macaques

open access: yesFrontiers in Immunology, 2019
Recent functional, gene expression, and epigenetic studies have suggested the presence of a subset of mature natural killer (NK) cells responsible for maintaining NK cell memory. The lack of endogenous clonal markers in NK cells impedes understanding the

Microsatellites within the feline androgen receptor are suitable for X chromosome-linked clonality testing in archival material [PDF]

open access: yes, 2016
Objectives A hallmark of neoplasms is their origin from a single cell; that is, clonality. Many techniques have been developed in human medicine to utilise this feature of tumours for diagnostic purposes.

Reversibility of lymphomas and lymphoproliferative lesions developing under cyclosporin-steroid therapy [PDF]

open access: yes, 1984
Post-transplant lymphomas or other lymphoproliferative lesions, which were usually associated with Epstein-Barr virus infections, developed in 8, 4, 3, and 2 recipients, respectively, of cadaveric kidney, liver, heart, and heart-lung homografts ...

Combination immunotherapy induces distinct T-cell repertoire responses when administered to patients with different malignancies. [PDF]

open access: yes, 2020
BackgroundCTLA-4 blockade with ipilimumab is Food and Drug Administration-approved for melanoma as a monotherapy and has been shown to modulate the circulating T-cell repertoire.

IGHV mutational status of nodal marginal zone lymphoma by NGS reveals distinct pathogenic pathways with different prognostic implications [PDF]

open access: yes, 2019
The precise B cell of origin and molecular pathogenesis of nodal marginal zone lymphoma (NMZL) remain poorly defined. To date, due to the rarity of NMZL, the vast majority of already-published studies have been conducted on a limited number of samples ...

Statistical Tests for Clonality [PDF]

open access: yesBiometrics, 2006
Summary Cancer investigators frequently conduct studies to examine tumor samples from pairs of apparently independent primary tumors with a view to determine whether they share a “clonal” origin. The genetic fingerprints of the tumors are compared using a panel of markers, often representing loss of heterozygosity (LOH) at distinct genetic loci.

Coexistence of Multiple Endemic and Pandemic Lineages of the Rice Blast Pathogen

open access: yesmBio, 2018
The rice blast fungus Magnaporthe oryzae (syn., Pyricularia oryzae) is both a threat to global food security and a model for plant pathology. Molecular pathologists need an accurate understanding of the origins and line of descent of M.

The role of anthropogenic dispersal in shaping the distribution and genetic composition of a widespread North American tree species

open access: yesEcology and Evolution, 2021
Dispersal and colonization are among the most important ecological processes for species persistence as they allow species to track changing environmental conditions.

Genetic Basis of Self-Incompatibility in the Lichen-Forming Fungus Lobaria pulmonaria and Skewed Frequency Distribution of Mating-Type Idiomorphs: Implications for Conservation [PDF]

open access: yes, 2012
Fungal populations that reproduce sexually are likely to be genetically more diverse and have a higher adaptive potential than asexually reproducing populations.
