Researchers Create Atlas of Protein-Coding Genes in Mammalian Brain

Genome-wide transcriptomics analysis of anatomically dissected regions in mammalian brains uncovers regional and species-specific expression: multiple regions of the human, pig, and mouse brain were dissected and analyzed; a uniform manifold approximation and projection (UMAP) analysis (middle) shows the global expression patterns of 1,710 samples in the human brain, with the cerebellum as the outlier; the Human Protein Atlas (HPA) Brain Atlas (right) shows the expression of individual genes, for example, synaptosomal-associated protein 25 (SNAP25), in the different brain regions in the three mammalian species.

The Brain Atlas explores the protein expression in the mammalian brain by visualization and integration of data from three species of mammals: human, pig and mouse. The open-access resource is based on the analysis of nearly 1,900 brain samples covering 27 brain regions. Genome-wide transcriptomics analysis of anatomically dissected regions in mammalian brains uncovers regional and species-specific expression: multiple regions of the human, pig, and...

Depiction of huge bacteriophages (red, left) and normal phages infecting a bacterial cell. The huge phage injects its DNA into the host cell, where Cas proteins -- part of the CRISPR immune system typically found only in bacteria and archaea -- manipulate the host cell’s response to other viruses. The authors have not yet photographed any huge phages, so all are depicted resembling the most common type of phage, T4. Image credit: Jill Banfield Lab / University of California, Berkeley.
