چکیده
A major limitation in understanding embryonic development is the lack of cell type-specific markers. Existing gene expression and marker atlases provide valuable tools, but they typically have one or more limitations: a lack of single-cell resolution; an inability to register multiple expression patterns to determine their precise relationship; an inability to be upgraded by users; an inability to compare novel patterns with the database patterns; and a lack of three-dimensional images. Here, we develop new ‘atlas-builder’ software that overcomes each of these limitations. A newly generated atlas is three-dimensional, allows the precise registration of an infinite number of cell type-specific markers, is searchable and is openended. Our software can be used to create an atlas of any tissue in any organism that contains stereotyped cell positions. We used the software to generate an ‘eNeuro’ atlas of the Drosophila embryonic CNS containing eight transcription factors that mark the major CNS cell types (motor neurons, glia, neurosecretory cells and interneurons). We found neuronal, but not glial, nuclei occupied stereotyped locations. We added 75 new Gal4 markers to the atlas to identify over 50% of all interneurons in the ventral CNS, and these lines allowed functional access to those interneurons for the first time. We expect the atlas-builder software to benefit a large proportion of the developmental biology community, and the eNeuro atlas to serve as a publicly accessible hub for integrating neuronal attributes – cell lineage, gene expression patterns, axon/dendrite projections, neurotransmitters – and linking them to individual neurons.

متن کاملProbing for semantic evidence of composition by means of simple classification tasks
We propose a diagnostic method for probing specific information captured in vector representations of sentence meaning, via simple classification tasks with strategically constructed sentence sets. We identify some key types of semantic information that we might expect to be captured in sentence composition, and illustrate example classification tasks for targeting this information.
متن کاملTranslating the molecular message of triple-negative breast cancer into targeted therapy.
Triple-negative breast cancer (TNBC) has a poor prognosis with limited treatment options. Genomic analysis of TNBCs offers the opportunity to decode TNBC into biologically relevant subtypes with unique molecular targets. With further research, these findings may be translated into effective targeted therapeutic options.
