The switch from mitotic cell cycles to the one meiotic cell cycle in each generation is triggered through dramatic upregulation of a broad gene expression program by transcriptional regulator STRA8.

Cell biological study reveals the mechanism by which multiple satellite-DNA-binding proteins cooperate to form chromocenter to encapsulate the full complement of chromosomes.

Depleting Mi-2 in the progeny of neural stem cells prevents normal enhancer decommissioning so that they become sensitive to Notch activity and re-acquire stem cell properties.
With the removal of confounding artifacts, ribosome profiling can yield insight into the mechanism of protein synthesis in bacteria at high resolution.

The histone chaperone FACT and the deubiquitinating enzyme Ubp10 act in concert to remove ubiquitin from histone H2B in nucleosomes, and likely coordinate nucleosome assembly during DNA replication and transcription.
The requirements for preinitiation complex formation/stability and transcription by RNA polymerase II in yeast cells are different from those in vitro, thereby altering the current view of basal transcription.
The MondoA transcription factor localizes to the outer mitochondrial membrane where it coordinates an adaptive transcriptional response to elevated cellular energy represented by high cytoplasmic glucose and high mitochondrial ATP.

The chromosome architectural protein, CTCF, is phosphorylated at Ser224 in a cell-cycle-dependent manner and abrogation of phosphorylation leads to a cell growth defect.
