Transgenic mice with high levels of FGF21 live for longer than wild-type mice and do so without reducing food intake.

A unique form of regulation has been observed in the unfolded protein response of S. pombe, along with a novel mechanism of post-transcriptional mRNA processing.

A combination of molecular dynamics simulations and X-ray diffraction data has been used to construct more realistic models of proteins and to provide new insights into their interactions with other proteins and biomolecules.

Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

Experiments in mice have shown than an enzyme that repairs broken DNA inside the nucleus also has a central role in the innate immune system because it is able to detect foreign DNA outside the nucleus.

Cleavage of a membrane-bound transcription factor by the chemotherapeutic reagent doxorubicin can block the proliferation of tumor cells.

The ability of epithelial cells to distinguish between domains on opposing cell surfaces within a tissue, a property known as planar cell polarity, relies on proteins and protein complexes directing the traffic of signaling proteins to specific locations on the cell surface membrane.

A combination of single-molecule imaging and an in vitro model of the cell cortex has allowed the interactions between actin filaments and filaments made of myosin II to be studied in detail.

The HITS-CLIP sequencing method is used to demonstrate that cryptic exons can detect messenger RNA that contains nonsense mutations, and then cause this RNA to decay, which shows that these exons are involved in maintaining the electrical balance of neurons and, possibly, preventing epilepsy.
