Purpose: Limited knowledge about disease mechanisms, few published cases, and the lack of functional assessment of variants for neurodevelopmental genetic disorders challenge diagnostic classification for variants and increase the frequency of variants of uncertain significance (VUS). Because inheritance patterns aid in variant interpretation for neurodevelopmental conditions, genetic testing including only the proband leads to larger numbers of VUS than testing strategies that include the parents.

Methods: We reinterpreted genetic variants submitted to the Simons Searchlight research registry using American College of Medical Genetics and Genomics variant interpretation guidelines, familial cascade testing, and literature curation with annual VUS reevaluation.

Ferroptosis is an oxidative, non-apoptotic cell death frequently inactivated in cancer, but the underlying mechanisms in oncogene-specific tumors remain poorly understood. Here, we discover that lactate dehydrogenase (LDH) B, but not the closely related LDHA, subunits of active LDH with a known function in glycolysis, noncanonically promotes ferroptosis defense in KRAS-driven lung cancer. Using murine models and human-derived tumor cell lines, we show that LDHB silencing impairs glutathione (GSH) levels and sensitizes cancer cells to blockade of either GSH biosynthesis or utilization by unleashing KRAS-specific, ferroptosis-catalyzed metabolic synthetic lethality, culminating in increased glutamine metabolism, oxidative phosphorylation (OXPHOS) and mitochondrial reactive oxygen species (mitoROS).

Nat Commun

November 2024

Conservation Science Group, Department of Zoology, University of Cambridge, Cambridge, UK.

Tidal marshes are threatened coastal ecosystems known for their capacity to store large amounts of carbon in their water-logged soils. Accurate quantification and mapping of global tidal marshes soil organic carbon (SOC) stocks is of considerable value to conservation efforts. Here, we used training data from 3710 unique locations, landscape-level environmental drivers and a global tidal marsh extent map to produce a global, spatially explicit map of SOC storage in tidal marshes at 30 m resolution.

Acute myeloid leukemia (AML) derives from hematopoietic stem and progenitor cells (HSPCs). To date, no AML-exclusive, non-HSPC-expressed cell-surface target molecules for AML selective immunotherapy have been identified. Therefore, to still apply surface-directed immunotherapy in this disease setting, time-limited combined immune-targeting of AML cells and healthy HSPCs, followed by hematopoietic stem cell transplantation (HSCT), might be a viable therapeutic approach.

Gamma aminobutyric acid type A receptors (GABARs) play a key role in the mammalian central nervous system (CNS) as drivers of neuroinhibitory circuits, which are commonly targeted for therapeutic purposes with potentiator drugs. However, due to their widespread expression and strong inhibitory action, systemic pharmaceutical potentiation of GABARs inevitably causes adverse effects regardless of the drug selectivity. Therefore, therapeutic guidelines must often limit or exclude clinically available GABAR potentiators, despite their high efficacy, good biodistribution, and favorable molecular properties.

Vapor flux induced by temperature gradient is responsible for providing liquid water to hypoliths.

Sci Rep

October 2024

Department of Environmental Systems Science, Swiss Federal Institute of Technology ETH, Universitätstrasse 16, Zürich, CH-8092, Switzerland.

Commonly comprised of cyanobacteria, algae, bacteria and fungi, hypolithic communities inhabit the underside of cobblestones and pebbles in diverse desert biomes. Notwithstanding their abundance and widespread geographic distribution and their growth in the driest regions on Earth, the source of water supporting these communities remains puzzling. Adding to the puzzle is the presence of cyanobacteria that require liquid water for net photosynthesis.

Article Synopsis
  • - The study explores the relationship between pain habituation (how pain response decreases over time) and conditioned pain modulation (CPM), which is a measure of the body’s ability to manage pain, in 45 healthy participants.
  • - Pain habituation was evaluated using subjective pain ratings and objective measures (CHEP and SSR) during heat stimuli, revealing significant variability in participants’ responses, particularly in subjective ratings.
  • - It was found that while subjective pain habituation correlated with cold-induced CPM effects, this correlation did not hold for other CPM measures, suggesting that subjective and objective pain responses may reflect different aspects of how our body modulates pain.

Article Synopsis
  • Left ventricular global longitudinal strain (LV-GLS) is a promising early marker for heart failure, and this study aimed to establish cut-off points to distinguish healthy hearts from those affected by heart failure using different imaging techniques.
  • The study analyzed data from healthy subjects and heart failure patients to determine LV-GLS cut-offs, finding values of -19.3% for fast strain-encoded imaging (fSENC) and -15.1% for feature tracking (FT) to differentiate healthy individuals from those with heart failure.
  • Both techniques effectively identify heart failure with consistent results, and a conversion factor was established to translate LV-GLS between fSENC and FT, suggesting a simplified threshold of -15% for FT

Neuronal hyperexcitability is a key driver of persistent pain states including neuropathic pain. Leucine-rich, glioma inactivated 1 (LGI1), is a secreted protein known to regulate excitability within the nervous system and is the target of autoantibodies from neuropathic pain patients. Therapies that block or reduce antibody levels are effective at relieving pain in these patients, suggesting that LGI1 has an important role in clinical pain.

Small energy benefits of in-wake flying in long-duration migratory flights.

Proc Biol Sci

January 2024

Waldrappteam Research and Conservation, Schulgasse 28 , Mutters 6162, Austria.

During long-distance migrations, some bird species make use of in-wake flying, which should allow them to profit from the upwash produced by another bird. While indirect evidence supports energy saving as the primary benefit of in-wake flying, measurements are still missing. We equipped migrating northern bald ibises () with high-precision global navigation satellite system data loggers to track their position in the flock.

Tumor-Homing Antibody-Cytokine Fusions for Cancer Therapy.

Onco Targets Ther

August 2024

Philochem AG, Otelfingen, 8112, Switzerland.

Recombinant cytokine products have emerged as a promising avenue in cancer therapy due to their capacity to modulate and enhance the immune response against tumors. However, their clinical application is significantly hindered by systemic toxicities already at low doses, thus preventing escalation to therapeutically active regimens. One promising approach to overcoming these limitations is using antibody-cytokine fusion proteins (also called immunocytokines).
