Integrative analyses of speciation and divergence in Psammodromus hispanicus (Squamata: Lacertidae)

open access: yesBMC Evolutionary Biology, 2011
Background Genetic, phenotypic and ecological divergence within a lineage is the result of past and ongoing evolutionary processes, which lead ultimately to diversification and speciation. Integrative analyses allow linking diversification to geological,

Population gene introgression and high genome plasticity for the zoonotic pathogen Streptococcus agalactiae [PDF]

open access: yes, 2019
The influence that bacterial adaptation (or niche partitioning) within species has on gene spillover and transmission among bacteria populations occupying different niches is not well understood.

Cytomegalovirus infection is common in prostate cancer and antiviral therapies inhibit progression in disease models

open access: yesMolecular Oncology, EarlyView.
Human cytomegalovirus infection is common in normal prostate epithelium, prostate tumor tissue, and prostate cancer cell lines. CMV promotes cell survival, proliferation, and androgen receptor signaling. Anti‐CMV pharmaceutical compounds in clinical use inhibited cell expansion in prostate cancer models in vitro and in vivo, motivating investigation ...

Molecular epidemiology of Mycobacterium africanum in Ghana [PDF]

open access: yes, 2016
BACKGROUND: Mycobacterium africanum comprises two phylogenetic lineages within the M. tuberculosis complex (MTBC) and is an important cause of human tuberculosis (TB) in West Africa. The reasons for this geographic restriction of M.

Beyond cytotoxic T cells: reprogrammed regulatory T cells help facilitate response to dual checkpoint blockade

open access: yesMolecular Oncology, EarlyView.
Rolig, Peng, and colleagues have shed new light on how dual blockade of PD1 and LAG3 enhances antitumor immunity. They found that response to immunotherapy with anti‐PD1 + anti‐LAG3 was associated with reprogramming of canonically suppressive CD4+ regulatory T cells to an inflammatory state.

Genotypic Diversity Is Associated with Clinical Outcome and Phenotype in Cryptococcal Meningitis across Southern Africa.

open access: yesPLoS Neglected Tropical Diseases, 2015
Cryptococcal meningitis is a major cause of mortality throughout the developing world, yet little is known about the genetic markers underlying Cryptococcal virulence and patient outcome.

Persistent Wnt/β-catenin signaling determines dorsalization of the postnatal subventricular zone and neural Stem cell specification into oligodendrocytes and glutamatergic neurons [PDF]

open access: yes, 2014
In the postnatal and adult central nervous system (CNS), the subventricular zone (SVZ) of the forebrain is the main source of neural stem cells (NSCs) that generate olfactory neurons and oligodendrocytes (OLs), the myelinating cells of the CNS.

Small modifier, big decision: switching to SUMO mode adds weight to cancer stemness in mammary tumors

open access: yesMolecular Oncology, EarlyView.
Inhibition of protein SUMOylation has been shown to block tumorigenesis; however, the specific mechanisms by which SUMOylation controls the tumor‐initiating capacities remain elusive. Li et al. describe the role of Etv1 SUMOylation in cancer stem cells using mouse models of mammary gland tumorigenesis.

Lineage specific recombination rates and microevolution in Listeria monocytogenes

open access: yesBMC Evolutionary Biology, 2008
Background The bacterium Listeria monocytogenes is a saprotroph as well as an opportunistic human foodborne pathogen, which has previously been shown to consist of at least two widespread lineages (termed lineages I and II) and an uncommon lineage ...

A Unifying Scenario on the Origin and Evolution of Cellular and Viral Domains [PDF]

open access: yes, 2009
The cellular theory on the nature of life has been one of the first major advancements in biology. Viruses, however, are the most abundant life forms, and their exclusion from mainstream biology and the Tree of Life (TOL) is a major paradox in biology ...
