When the NXF1 gene functions properly, RNA of a single-exon gene is exported

Cells use two separate routes to export RNA out of the nucleus

Asking a different question about the bacteria in our microbiomes might help target disease more precisely

The reproduction rates of the bacteria in one's gut may be a good indicator of health or disease


Gene expression of schizophrenia-related genes. 1,028 genes with very similar expression profiles are shown, one to a row, and 480 samples are arrayed in the columns. Red-to-blue shows the strength of the gene's expression level, red being stronger

New research reveals a cluster of genetic “typos” that may increase the risk of schizophrenia

Algorithm-generated comparisons among the genomes of cells from 450 tissue samples: The analysis revealed a striking similarity (red colors, upper right rectangle) in tRNA signatures among cancerous cells and healthy dividing cells, as well as a degree of similarity among the non-dividing cells (red colors, lower left rectangle), whereas no such similarity (blue) was found when dividing cells were compared with non-dividing ones

Synonyms in the gene code spell differences in cell division
