The Challenge of a Siberian Bluegrass (Poa) Phylogeny [PDF]

open access: yes, 2010
In Siberia, the bluegrass genus (Poa) comprises 43 species and 61 subspecies in 12 sections. Diverse modes of speciation, including polyploidy and hybridization, have led to reticulate evolution and adaptive radiation.

Re-evaluating homoploid reticulate evolution in the annual sunflowers

open access: yesbioRxiv, 2022
Sunflowers of the genus Helianthus are models for hybridization research and contain three of the best studied examples of homoploid hybrid speciation. To understand the broader picture of hybridization within the annual sunflowers, we used whole genome ...

Evidence for Widespread Reticulate Evolution within Human Duplicons [PDF]

open access: yesThe American Journal of Human Genetics, 2005
Approximately 5% of the human genome consists of segmental duplications that can cause genomic mutations and may play a role in gene innovation. Reticulate evolutionary processes, such as unequal crossing-over and gene conversion, are known to occur within specific duplicon families, but the broader contribution of these processes to the evolution of ...

Intein‐based modular chimeric antigen receptor platform for specific CD19/CD20 co‐targeting

open access: yesMolecular Oncology, EarlyView.
CARtein is a modular CAR platform that uses split inteins to splice antigen‐recognition modules onto a universal signaling backbone, enabling precise, scarless assembly without re‐engineering signaling domains. Deployed here against CD19 and CD20 in B‐cell malignancies, the design supports flexible multi‐antigen targeting to boost T‐cell activation and

The use of chloroplast genome sequences to solve phylogenetic incongruences in Polystachya Hook (Orchidaceae Juss) [PDF]

open access: yes, 2018
Background: Current evidence suggests that for more robust estimates of species tree and divergence times, several unlinked genes are required. However, most phylogenetic trees for non-model organisms are based on single sequences or just a few regions ...

Improving PARP inhibitor efficacy in bladder cancer without genetic BRCAness by combination with PLX51107

open access: yesMolecular Oncology, EarlyView.
Clinical trials on PARP inhibitors in urothelial carcinoma (UC) showed limited efficacy and a lack of predictive biomarkers. We propose SLFN5, SLFN11, and OAS1 as UC‐specific response predictors. We suggest Talazoparib as the better PARP inhibitor for UC than Olaparib.

Plant kleptomaniacs: geographical genetic patterns in the amphi-apomictic Rubus ser. Glandulosi (Rosaceae) reveal complex reticulate evolution of Eurasian brambles

open access: yesbioRxiv
Rubus ser. Glandulosi represents a unique model of geographic parthenogenesis on a homoploid (4x) level. We employed double digest restriction-site associated DNA sequencing (ddRADseq) in 587 individuals of different Rubus taxa and modelling of suitable ...

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Exploring phylogenetic hypotheses via Gibbs sampling on evolutionary networks

open access: yesBMC Genomics, 2016
Background Phylogenetic networks are leaf-labeled graphs used to model and display complex evolutionary relationships that do not fit a single tree. There are two classes of phylogenetic networks: Data-display networks and evolutionary networks.

A bajocian (Middle jurassic) marine gastropod assemblage from the badamu formation, Central Iran [PDF]

open access: yes, 2016
Nine species of gastropods are reported from the Bajocian (Middle Jurassic) part of the Badamu Formation of Central Iran. This is the first report of a gastropod assemblage of this age from the shelves of the Kimmerian Continent.
