Cryo-electron microscopy structures, combined with biochemical experiments, show how the E. coli F element-encoded TraR protein regulates transcription initiation by altering RNA polymerase conformation and conformational heterogeneity.
Stochasticity introduced computationally into a gene expression oscillator creates heterogeneity in the time of differentiation of identical cells and offers robustness to the progenitor state and the outcome of cell division.
In isogenically matched colorectal cancer (CRC) cell lines, mutant KRAS alters the composition of secreted miRNAs in extracellular vesicles that can then transfer repressive activity to wild type cells.
A novel method predicts cancer and immune cell types from bulk tumor gene expression data with the ability to consider uncharacterized and possibly highly variable cell types, which is validated in human genome.
The molecular microenvironment of coronaviral replicase complexes provides functional and spatial links between conserved cellular processes and viral RNA synthesis, and highlights potential targets for the development of novel antivirals.
The three-dimensional structures of 50 sensory cilia present in the head of the adult C. elegans hermaphrodite have been reconstructed to provide a foundation for investigations into the mechanisms by which the diversity of cilia structures is generated and how this structural diversity is related to specific sensory neuron functions.
