Alba domain-containing proteins are ubiquitously found in archaea and eukaryotes. By binding to either DNA, RNA, or DNA:RNA hybrids, these proteins function in genome stabilization, chromatin organization, gene regulation, and/or translational modulation. In the malaria parasite , six Alba domain proteins PfAlba1-6 have been described, of which PfAlba1 has emerged as a "master regulator" of translation during parasite intra-erythrocytic development (IED).

Over the past decade, immune checkpoint inhibitors (ICIs) have transformed the treatment of cancer, though they come with the risk of immune-related adverse (irAEs) events such as hepatotoxicity or Immune-mediated Liver Injury from Checkpoint Inhibitors (ILICI). ILICI is a serious irAE that, when severe, requires cessation of ICI and initiation of immunosuppression. Cytotoxic T Lymphocytes (CTLs) play a central role in ILICI; however, they are just part of the picture as immunotherapy broadly impacts all aspects of the immune microenvironment and can directly and indirectly activate innate and adaptive immune cells.

Background: Achieving a durable mitral line block using radiofrequency as a part of an anatomical approach for ablation in patients with persistent atrial fibrillation or for treating peri-mitral flutter has always been challenging due to the complex anatomy of the mitral isthmus. Epicardial ablation via the coronary sinus and the vein of Marshall has been proposed to help create durable lesions. Recently, a novel lattice-tip catheter using pulsed field ablation has shown promising results for creating mitral lines, despite limited data.

Introduction: We explored which dementia risk factors in two multidomain prevention trials mediate beneficial, neutral, or counteracting effects on dementia incidence.
Methods: We pooled data from the multidomain MAPT (Multidomain Alzheimer Preventive Trial; n = 1679, up to 5-year follow-up) and preDIVA trials (Prevention of Dementia by Intensive Vascular Care; n = 3526, up to 12-year follow-up) in adults aged 70+. We used multiple mediation analysis to quantify the role of 2-year changes in body mass index, systolic blood pressure, total cholesterol, and physical activity in the intervention effects on dementia incidence.

Retroviruses carry a genomic intron-containing RNA with a long structured 5'-untranslated region, which acts either as a genome encapsidated in the viral progeny or as an mRNA encoding the key structural protein, Gag. We developed a single-molecule microscopy approach to simultaneously visualize the viral mRNA and the nascent Gag protein during translation directly in the cell. We found that a minority of the RNA molecules serve as mRNA and that they are translated in a fast and efficient process.

In the animal kingdom, metamorphosis is a well-known developmental transition within various taxa (Cnidarians, Echinoderms, Molluscs, Arthropods, Vertebrates, etc.), which is characterized by the switching from a larval stage to an adult form through the induction of morpho-anatomical, physiological, behavioral, and/or ecological changes. Over the last decades, numerous studies have focused on the hormonal control of cellular processes underlying metamorphosis.

Insects and flowering plants are the most abundant and diverse multicellular organisms on Earth, accounting for 75% of known species. Their evolution has been largely interdependent since the so-called Angiosperm Terrestrial Revolution (100-50 Mya), when the explosion of plant diversity stimulated the evolution of pollinating and herbivorous insects. Plant-insect interactions rely heavily on chemical communication via volatile organic compounds (VOCs).

During recent years, much progress has been made in understanding the origin and evolution of the dog. Thanks to the collaboration between zooarchaeology, genomics and paleogenetics, researchers were able to hypothesize scenarios regarding the origins of the canine lineages present in Europe at the end of the Pleistocene and the beginning of the Holocene. Research has also shown a correlation between human and canine migration across time and space, highlighting a strong relationship between man and his best friend.

The disruption of proteostasis provides a favourable context for the emergence of therapeutic innovations, in particular by exploiting technologies such as the PROTAC (Proteolysis Targeting Chimera) approach. These technologies aim to selectively target proteins involved in various diseases, including cancer and neurodegenerative diseases, by inducing their specific degradation via the ubiquitin-proteasome system. The PROTAC approach opens new opportunities for restoring altered protein homeostasis and modulating the pathological consequences of proteostasis deregulation.

In the anthropocene era, one of the greatest challenges facing trophic modeling applied to the marine environment is its ability to couple the multiple effects of both climate change and local anthropogenic activities, notably the development of offshore wind farms. The major challenge is to create scenarios to characterize their cumulative effects on the functioning of the entire socio-ecological system, in order to propose appropriate management plans. Although modeling cumulative impact on socio-ecological networks is not yet widely used, data reported in the present review article show that the relevance of this approach could be established in the context of offshore wind power.

The advent of high-throughput omics data and the generation of new algorithms provide the biologists with the opportunity to explore living processes in the context of systems biology aiming at revealing the gene interactions, the networks underlying complex cellular functions. In this article, we discuss two methods for gene network reconstruction, WGCNA (Weighted Gene Correlation Network Analysis) developed by Steve Horvath and collaborators in 2008, and MIIC (Multivariate Information-based Inductive Causation) developed by Hervé Isambert and his team in 2017 and 2024. These two methods are complementary, WGCNA generating undirected networks in which most gene-to-gene interactions are indirect, while MIIC reveals direct interactions and some causal links.
