Exosomes from cancer-associated fibroblasts enhance the "Warburg effect" in tumors and contain de novo metabolites that can contribute to the entire compendia of central carbon metabolism within cancer cells.
Impaired autophagy influences intestinal inflammation and hypersensitivity responses by orchestrating mucosal T cell populations, suggesting new translational perspectives for the treatment of these conditions.
The reanalysis of data from a recent study that claimed retrotransposon mutations are ubiquitous in the human brain outlines a general framework for the design and analysis of single-cell genomics studies.
Neuronal ELAV-like (nELAVL) proteins are associated with non-coding Y RNAs in stressed neurons and in the brains of Alzheimer's disease patients, suggesting a new means of regulatory protein sequestration and mRNA target regulation.
Chemical inhibition of Bub1 shows that the catalytic activity is not required for normal mitotic progression, but it makes chromosome segregation and cell proliferation more sensitive to the effects of the anti-cancer drug Paclitaxel.
Mutants of influenza A virus with increased CpG dinucleotide frequencies show restricted replication and reduced or absent pathogenicity, and powerful host innate and adaptive responses to infection that confer immunity to re-infection.
In the fruit fly Drosophila melanogaster, stem cell activity ages female guts but not male guts; furthermore, males with feminized guts develop pathologies but gain an increase in lifespan through dietary restriction.
The Acyl-CoA binding domain-containing 7 (Acbd7) gene is expressed in the hypothalamus, encodes a peptide that suppresses appetite, increases metabolic rate and interacts with the leptin-melanocortin system.
Expression of Drosophila bitter receptors in taste neurons produced increased, decreased, or novel responses, supporting a model in which the response profile is determined by activation, inhibition, or competition among receptors.
The transition from bad to good treatments for HIV was accompanied by a shift from soft sweeps of many drug resistance mutations spreading simultaneously to harder sweeps of one drug resistant genotype at a time.
Time-lapse recording and theoretical analysis of individual cells isolated from the zebrafish segmentation clock reveal that they behave as self-sustained, autonomous oscillators with distinctive noisy dynamics.
Antagonistic signaling by the kinases PI3K and Itpkb limits the kinetics and enforces the Notch-dependence of beta-selection – the most important cell-fate determining process in alpha beta T cell development.
Genetic and biochemical evidence shows that the basal transcription machinery of muscle cells invariably relies on TBP/TFIID because TBP2 is not expressed in muscle cells, and thus resolves a longstanding issue raised by previous conflicting data.
The structure of a bivalent double-knot tarantula toxin bound to the outer pore of the capsaicin receptor reveals a novel mode of toxin-channel recognition that has important implications for thermosensation.
In an investigation into the effects of drugs on proteins, an active machine learning algorithm chose which sets of experiments to perform and was able to learn an accurate model of the effects after doing only a fraction of the experiments.
Nucleolar protein localization involves the phase separation within the nucleolar matrix via three types of multivalent features: acidic tracts, nucleic acid binding domains and arginine-rich low complexity sequences.
A lipid mediator lysophosphatidic acid (LPA) derived from fibroblastic reticular cells regulates T-cell movement through the densely packed reticular network in lymph nodes in a manner dependent on the LPA receptor LPA2-ROCK-myosin II.
Two common mutant versions of estrogen receptor alpha achieve constitutive activity and hormone-resistance by preferentially adopting a suite of conformations that expose the coregulator-binding surface.
The maternally provided histone demethylase LSD1/KDM1A has an instrumental role at the beginning of life, shaping the histone methylation landscape and the transcriptional repertoire of the early mouse embryo.
