A probabilistic model for gene content evolution with duplication, loss, and horizontal transfer

open access: yes, 2005
We introduce a Markov model for the evolution of a gene family along a phylogeny. The model includes parameters for the rates of horizontal gene transfer, gene duplication, and gene loss, in addition to branch lengths in the phylogeny. The likelihood for

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

open access: yesMolecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.

Evidence of Massive Horizontal Gene Transfer Between Humans and Plasmodium vivax [PDF]

open access: yes, 2011
The horizontal transfer of DNA between different organisms is a major force shaping the genomes of prokaryotes, but is considered to have a minor role in eukaryotes, with only a handful of known examples, mostly of limited size.

Predictors of response and rational combinations for the novel MCL‐1 inhibitor MIK665 in acute myeloid leukemia

open access: yesMolecular Oncology, EarlyView.
This study characterizes the responses of primary acute myeloid leukemia (AML) patient samples to the MCL‐1 inhibitor MIK665. The results revealed that monocytic differentiation is associated with MIK665 sensitivity. Conversely, elevated ABCB1 expression is a potential biomarker of resistance to the treatment, which can be overcome by the combination ...

Horizontal gene transfer in bacteria: an ecological and evolutionary perspective

open access: yesActa Agriculturae Slovenica, 2000
In recent years, molecular genetics and genome analysis provided extensive evidence that gene loss and acquisition are likely to be the primary mechanisms by which bacteria genetically adapt to novel or changed environments and by which bacterial ...

Horizontal gene transfer contributed to the evolution of extracellular surface structures [PDF]

open access: yes, 2012
The single-cell layered ectoderm of the fresh water polyp Hydra fulfills the function of an epidermis by protecting the animals from the surrounding medium.

Molecular characterisation of human penile carcinoma and generation of paired epithelial primary cell lines

open access: yesMolecular Oncology, EarlyView.
Generation of two normal and tumour (cancerous) paired human cell lines using an established tissue culture technique and their characterisation is described. Cell lines were characterised at cellular, protein, chromosome and gene expression levels and for HPV status.

Gene silencing and large-scale domain structure of the E. coli genome

open access: yes, 2012
The H-NS chromosome-organizing protein in E. coli can stabilize genomic DNA loops, and form oligomeric structures connected to repression of gene expression.

LINC01116, a hypoxia‐lncRNA marker of pathological lymphangiogenesis and poor prognosis in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...

Topological data analysis captures horizontal gene transfer in antimicrobial resistance gene families among clinically relevant bacteria

open access: yesFrontiers in Microbiology
Antibiotic resistance, projected to cause 10 million deaths annually by 2050, remains a critical health threat. Hospitals drive multidrug resistance via horizontal gene transfer.
