Statistical Inference of Allopolyploid Species Networks in the Presence of Incomplete Lineage Sorting [PDF]

open access: yesSystematic Biology, 2013
Polyploidy is an important speciation mechanism, particularly in land plants. Allopolyploid species are formed after hybridization between otherwise intersterile parental species. Recent theoretical progress has led to successful implementation of species tree models that take population genetic parameters into account.

Non-parametric correction of estimated gene trees using TRACTION

open access: yesAlgorithms for Molecular Biology, 2020
Motivation Estimated gene trees are often inaccurate, due to insufficient phylogenetic signal in the single gene alignment, among other causes. Gene tree correction aims to improve the accuracy of an estimated gene tree by using computational techniques ...

Human prostate sphere-forming cells represent a subset of basal epithelial cells capable of glandular regeneration in vivo. [PDF]

open access: yes, 2009
BackgroundProstate stem/progenitor cells function in glandular development and maintenance. They may be targets for tumor initiation, so characterization of these cells may have therapeutic implications.

Inferring Kangaroo Phylogeny from Incongruent Nuclear and Mitochondrial Genes [PDF]

open access: yes, 2015
The marsupial genus Macropus includes three subgenera, the familiar large grazing kangaroos and wallaroos of M. (Macropus) and M. (Osphranter), as well as the smaller mixed grazing/browsing wallabies of M. (Notamacropus).

Simulation-Based Evaluation of Hybridization Network Reconstruction Methods in the Presence of Incomplete Lineage Sorting. [PDF]

open access: yesEvol Bioinform Online, 2017
Hybridization events generate reticulate species relationships, giving rise to species networks rather than species trees. We report a comparative study of consensus, maximum parsimony, and maximum likelihood methods of species network reconstruction using gene trees simulated assuming a known species history.

An approximate likelihood method reveals ancient gene flow between human, chimpanzee and gorilla

open access: yesPeer Community Journal
Gene flow and incomplete lineage sorting are two distinct sources of phylogenetic conflict, i.e., gene trees that differ in topology from each other and from the species tree.

Coalescent histories on phylogenetic networks and detection of hybridization despite incomplete lineage sorting. [PDF]

open access: yesSyst Biol, 2011
Analyses of the increasingly available genomic data continue to reveal the extent of hybridization and its role in the evolutionary diversification of various groups of species. We show, through extensive coalescent-based simulations of multilocus data sets on phylogenetic networks, how divergence times before and after hybridization events can result ...

An analytical comparison of coalescent-based multilocus methods: The three-taxon case [PDF]

open access: yes, 2012
Incomplete lineage sorting (ILS) is a common source of gene tree incongruence in multilocus analyses. A large number of methods have been developed to infer species trees in the presence of ILS.

Decellularized Extracellular Matrix (dECM) in Tendon Regeneration: A Comprehensive Review

open access: yesAdvanced Healthcare Materials, EarlyView.
Decellularized Extracellular Matrix (dECM) offers a promising solution by replicating the native tendon microenvironment and promoting regeneration. This review highlights advances in the decellularization methods, as well as their integration with emerging technologies and translational progress in tendon tissue engineering.

Engineered ETS1‐Nanoconjugate Restores Immune Homeostasis through Dual Immune‐Vascular Modulation in Relapsing and Progressive Multiple Sclerosis

open access: yesAdvanced Healthcare Materials, EarlyView.
The biomimetic nanoplatform IMNP (ETS1 pDNA/PBAE@ITP‐MM) undergoes targeted disassembly at inflammatory vascular sites to release the ETS1 plasmid (pETS1). This release initiates a cascade of effects that inhibit pathogenic pathways and support immune homeostasis. (Abbreviations: EndMT, endothelial‐to‐mesenchymal transition; EC, endothelial cell; TC, T
