Structure-Activity Relationship Studies of an Autophagy Inhibitor That Targets the ATG14L-Beclin1 Protein-Protein Interaction Reveal Modifications That Improve Potency and Solubility and Maintain Selectivity.

Autophagy, a recycling process in eukaryotes, contributes to tumor growth and metastasis by alleviating cellular stress and facilitating survival and chemoresistance. The development of small molecules that selectively inhibit this pathway has proven challenging and is required to determine if autophagy inhibition can be harnessed as an effective therapeutic strategy in cancer. Compound 19 was previously identified as a selective autophagy inhibitor that targets the ATG14L-Beclin1 protein-protein interaction, which regulates the formation, localization, and function of VPS34 Complex I to initiate autophagy.

Distinct and interdependent functions of three RING proteins regulate recombination during mammalian meiosis.

During meiosis, each pair of homologous chromosomes becomes connected by at least one crossover, as required for accurate segregation, and adjacent crossovers are widely separated thereby limiting total numbers. In coarsening models, this crossover patterning results from nascent recombination sites competing to accrue a limiting pro-crossover RING-domain protein (COR) that diffuses between synapsed chromosomes. Here, we delineate the localization dynamics of three mammalian CORs in the mouse and determine their interdependencies.

Characterizing progenitor cells in developing and injured spinal cord: Insights from single-nucleus transcriptomics and lineage tracing.

In this study, we present a cross-species investigation that extends from development to injury.

Integrative proteogenomic analyses provide novel interpretations of type 1 diabetes risk loci through circulating proteins.

Circulating proteins may be promising biomarkers or drug targets. Leveraging genome-wide association studies of type 1 diabetes (18,942 cases and 501,638 controls of European ancestry) and circulating protein abundances (10,708 European ancestry individuals), Mendelian randomization analyses were conducted to assess the associations between circulating abundances of 1,560 candidate proteins and the risk of type 1 diabetes, followed by multiple sensitivity and colocalization analyses, horizontal pleiotropy examinations, and replications. Bulk tissue and single-cell gene expression enrichment analyses were performed to explore candidate tissues and cell types for prioritized proteins.

Malian field isolates provide insight into Plasmodium malariae intra-erythrocytic development and invasion.

Plasmodium malariae is the third most prevalent human malaria parasite species and contributes significantly to morbidity. Nevertheless, our comprehension of this parasite's biology remains limited, primarily due to its frequent co-infections with other species and the lack of a continuous in vitro culture system. To effectively combat and eliminate this overlooked parasite, it is imperative to acquire a better understanding of this species.

Endocytosis of Wnt ligands from surrounding epithelial cells positions microtubule nucleation sites at dendrite branch points.

Microtubule nucleation is important for microtubule organization in dendrites and for neuronal injury responses. The core nucleation protein, γTubulin (γTub), is localized to dendrite branch points in Drosophila sensory neurons by Wnt receptors and scaffolding proteins on endosomes. However, whether Wnt ligands are important is unknown.

Leveraging cancer mutation data to inform the pathogenicity classification of germline missense variants.

Neuropeptide Y in cancer-biological functions and potential clinical implications.

Neuropeptide Y (NPY) is a sympathetic neurotransmitter widely distributed in the peripheral and central nervous system, affecting many physiological functions. Consequently, dysregulation of the NPY system contributes to numerous pathological disorders, including stress, obesity, and cancer. The pleiotropic functions of NPY in humans are mediated by G protein-coupled receptors (Y1R, Y2R, Y5R), which activate several signaling pathways and thereby regulate cell growth, differentiation, apoptosis, proliferation, angiogenesis, and metabolism.

Retinal OCT-Derived Texture Features as Potential Biomarkers for Early Diagnosis and Progression of Diabetic Retinopathy.

Purpose: Diabetic retinopathy (DR) is usually diagnosed many years after diabetes onset. Indeed, an early diagnosis of DR remains a notable challenge, and, thus, developing novel approaches for earlier disease detection is of utmost importance. We aim to explore the potential of texture analysis of optical coherence tomography (OCT) retinal images in detecting retinal changes in streptozotocin (STZ)-induced diabetic animals at "silent" disease stages when early retinal molecular and cellular changes that cannot be clinically detectable are already occurring.

Immobile Integrin Signaling Transit and Relay Nodes Organize Mechanosignaling through Force-Dependent Phosphorylation in Focal Adhesions.

Transmembrane signaling receptors, such as integrins, organize as nanoclusters that provide several advantages, including increasing avidity, sensitivity (increasing the signal-to-noise ratio), and robustness (signaling threshold) of the signal in contrast to signaling by single receptors. Furthermore, compared to large micron-sized clusters, nanoclusters offer the advantage of rapid turnover for the disassembly of the signal. However, whether nanoclusters function as signaling hubs remains poorly understood.
