Adapting systems biology to address the complexity of human disease in the single-cell era.

Systems biology aims to achieve holistic insights into the molecular workings of cellular systems through iterative loops of measurement, analysis and perturbation. This framework has had remarkable success in unicellular model organisms, and recent experimental and computational advances - from single-cell and spatial profiling to CRISPR genome editing and machine learning - have raised the exciting possibility of leveraging such strategies to prevent, diagnose and treat human diseases. However, adapting systems-inspired approaches to dissect human disease complexity is challenging, given that discrepancies between the biological features of human tissues and the experimental models typically used to probe function (which we term 'translational distance') can confound insight.

Enhancing transporter activity in heterologous expression systems with SAHA: a 2500-times more potent and odorless alternative to butyrate.

The functional characterization of plasma membrane transport proteins often relies on their heterologous expression in cultured cells. However, some transporters exhibit low activity, hindering meaningful functional assays. Heterologous expression is usually based on strong viral promoters which in living cells are prone to promoter silencing, a major problem.

Two-Dimensional Siloxene Nanosheets: Understanding the Effect of Heat Treatment on the Surface Chemistry and Resulting Electrochemistry in Lithium-Based Batteries.

Two-dimensional (2D) silicon materials are conceptually appealing as negative electrode materials in lithium-ion batteries due to their layered morphology, which can accommodate (de)lithiation-induced volume changes. Herein, heat treatment of 2D Siloxene materials was used to modify the surface functional groups to determine the impact on the electrochemical behavior. Spectroscopic characterization of the heat-treated nanosheets confirmed the loss of oxygenated and hydride surface functional groups with an increased annealing temperature.

Programs, origins and immunomodulatory functions of myeloid cells in glioma.

Gliomas are incurable malignancies notable for having an immunosuppressive microenvironment with abundant myeloid cells, the immunomodulatory phenotypes of which remain poorly defined. Here we systematically investigate these phenotypes by integrating single-cell RNA sequencing, chromatin accessibility, spatial transcriptomics and glioma organoid explant systems. We discovered four immunomodulatory expression programs: microglial inflammatory and scavenger immunosuppressive programs, which are both unique to primary brain tumours, and systemic inflammatory and complement immunosuppressive programs, which are also expressed by non-brain tumours.

(Acari: Psoroptidae) infestations in Southern pudus (): and data of an unexpected host-parasite record.

(Acari: Psoroptidae) constitutes an obligate, non-burrowing ectoparasite and causes otodectic mange primarily in domestic and wild carnivores. Only few studies have described this parasite in herbivore hosts so far. In the current study, we report infestations in Southern pudus (), categorized in the IUCN red list as near threatened.
