p53-loss induced prostatic epithelial cell plasticity and invasion is driven by a crosstalk with the tumor microenvironment.

Prostate cancer is a heterogeneous disease with a slow progression and a highly variable clinical outcome. The tumor suppressor genes PTEN and TP53 are frequently mutated in prostate cancer and are predictive of early metastatic dissemination and unfavorable patient outcomes. The progression of solid tumors to metastasis is often associated with increased cell plasticity, but the complex events underlying TP53-loss-induced disease aggressiveness remain incompletely understood.

A branching model for intergenerational telomere length dynamics.

We build and study an individual based model of the telomere length's evolution in a population across multiple generations. This model is a continuous time typed branching process, where the type of an individual includes its gamete mean telomere length and its age. We study its Malthusian's behaviour and provide numerical simulations to understand the influence of biologically relevant parameters.

Exogenous dsRNA triggers sequence-specific RNAi and fungal stress responses to control Magnaporthe oryzae in Brachypodium distachyon.

In vertebrates and plants, dsRNA plays crucial roles as PAMP and as a mediator of RNAi. How higher fungi respond to dsRNA is not known. We demonstrate that Magnaporthe oryzae (Mo), a globally significant crop pathogen, internalizes dsRNA across a broad size range of 21 to about 3000 bp.

PGT-A: what's it for, what's wrong?

PGT-A, what's it for? Considering the increase in fetal aneuploidies with a woman's age and the high number of miscarriages associated with fetal karyotype anomalies, the concept of selecting IVF embryos based on their karyotype in order to transfer only euploid embryos and eliminate aneuploid ones was proposed. Preimplantation genetic testing for aneuploidy (PGT-A) was then established, nearly 30 years ago, with the expectation that the transfer of euploid embryos would lead to a significant improvement in medically assisted reproduction (MAR) outcomes. PGT-A, what's wrong? Despite the practice and widespread use, PGT-A has not consistently proven its effectiveness.

Phenomenological Modeling of Antibody Response from Vaccine Strain Composition.

The elicitation of broadly neutralizing antibodies (bnAbs) is a major goal of vaccine design for highly mutable pathogens, such as influenza, HIV, and coronavirus. Although many rational vaccine design strategies for eliciting bnAbs have been devised, their efficacies need to be evaluated in preclinical animal models and in clinical trials. To improve outcomes for such vaccines, it would be useful to develop methods that can predict vaccine efficacies against arbitrary pathogen variants.

Salt-Compact Albumin as a New Pure Protein-based Biomaterials: From Design to In Vivo Studies.

Current biodegradable materials are facing many challenges when used for the design of implantable devices because of shortcomings such as toxicity of crosslinking agents and degradation derivatives, limited cell adhesion, and limited immunological compatibility. Here, a class of materials built entirely of stable protein is designed using a simple protocol based on salt-assisted compaction of albumin, breaking with current crosslinking strategies. Salt-assisted compaction is based on the assembly of albumin in the presence of high concentrations of specific salts such as sodium bromide.

DECORIN, a triceps-derived myokine, protects sorted β-cells and human islets against chronic inflammation associated with type 2 diabetes.

Aim: Pancreatic β-cells are susceptible to inflammation, leading to decreased insulin production/secretion and cell death. Previously, we have identified a novel triceps-derived myokine, DECORIN, which plays a pivotal role in skeletal muscle-to-pancreas interorgan communication. However, whether DECORIN can directly impact β-cell function and susceptibility to inflammation remains unexplored.

A Robust -Symmetric Aluminate Hydride for CO Hydroboration Catalysis: Mechanistic Insights and Countercation Influence on Catalytic Performance.

The present study details the synthesis and characterization of a robust, monomeric Al-H aluminate supported by a tridentate -phenolate ligand, isolated as [][Li(THF)] and [][N(Bu)] salts, which were then exploited as CO hydroboration catalysts. As initial reactivity studies, it was observed that the nucleophilic Al-H anion in [][C] (C = countercation [Li(THF)] or [N(Bu)]) reacts fast with CO, to afford the corresponding Al-formate complexes [][C], which were isolated and structurally characterized. Such anions were then exploited as potential CO reduction catalysts.
