The miRNA bantam regulates growth and tumorigenesis by repressing the cell cycle regulator tribblesThis work identifies the cell cycle regulator tribbles as a target of the miRNA bantam involved in the growth regulatory and oncogenic functions of bantam in Drosophila epithelia.
TAF-ChIP: an ultra-low input approach for genome-wide chromatin immunoprecipitation assayThe authors present a novel method for obtaining chromatin profiles from low cell numbers without prior nuclei isolation. The method is successfully implemented in generating epigenetic profile from 100 cells with high signal-to-noise ratio.
PRDM9 forms a trimer by interactions within the zinc finger arrayPRDM9 forms a trimer as a soluble protein and in complex with DNA mediated by the ZnF domain. Five ZnFs are already sufficient for multimerization and only one DNA molecule is complexed in the trimer.
Membrane curvature sensing of the lipid-anchored K-Ras small GTPaseProteolipid nanoassemblies of K-Ras and lipids in the plasma membrane sense changing membrane curvature architecture and convert mechanical perturbations to mitogenic signaling.
Human DNA polymerase delta requires an iron–sulfur cluster for high-fidelity DNA synthesisThe iron–sulfur cluster in human DNA polymerase delta has an impact on DNA polymerase and exonuclease activities and can hence influence the fidelity of DNA synthesis.
De novo prediction of cell-type complexity in single-cell RNA-seq and tumor microenvironmentsThis study describes a computational method for determining statistical support to varying levels of heterogeneity provided by single-cell RNA-sequencing data with applications to tumor samples.
Systematic identification of recognition motifs for the hub protein LC8LC8 is a eukaryotic hub protein that interacts with multifarious partners; analysis of more than 100 binding/nonbinding sequences led to an algorithm that predicts LC8 partners with 78% accuracy.
Fibril-induced glutamine-/asparagine-rich prions recruit stress granule proteins in mammalian cellsThis study provides evidence that exogenous proteinaceous seeds can induce protein aggregates that sequester stress granule components independent of stress granule assembly.
Dietary restriction induces posttranscriptional regulation of longevity genesBy modulating posttranscriptional processes, including RNA editing, miRNA biogenesis, and intron retention, dietary restriction enacts some of its pro-longevity benefits in Caenorhabditis elegans through posttranscriptional regulation of gene expression.
The cancer cell proteome and transcriptome predicts sensitivity to targeted and cytotoxic drugsThis study shows that the proteomic and transcriptomic states of cancer cells are more predictive of drug sensitivity than genomic markers for most drugs, both within and across tumor types.
