  • Inorganic nitrate and nitrite from endogenous or dietary sources are metabolized in vivo to nitric oxide (NO) and other bioactive nitrogen oxides. The nitrate-nitrite-NO pathway is emerging as an important mediator of blood flow regulation, cell signaling, energetics and tissue responses to hypoxia. The latest advances in our understanding of the biochemistry, physiology and therapeutics of nitrate, nitrite and NO were discussed during a recent 2-day meeting at the Nobel Forum, Karolinska Institutet in Stockholm.

  • García-Prat, Perdiguero, Alonso-Martín et al. show that skeletal muscle contains a subpopulation of quiescent stem cells, maintained by FoxO signalling, that is preserved into late life but declines in advanced geriatric age.

  • Some antiseizure medications including valporate are associated with neurodevelopmental conditions in children exposed in utero but evidence is less clear for other drugs. Here the authors investigate associations between antiseizure medication use in pregnancy and neurodevelopmental conditions using electronic health record data from the UK and Sweden.

  • The authors defined a roadmap for investigating the genetic covariance between structural or functional brain phenotypes and risk for psychiatric disorders. Their proof-of-concept study using the largest available common variant data sets for schizophrenia and volumes of several (mainly subcortical) brain structures did not find evidence of genetic overlap.

  • Of the 342 planets so far discovered orbiting other stars, 58 'transit' the stellar disk; the light from the star passes through the atmosphere of the planet, and in a few cases the basic atmospheric composition of the planet can be estimated. The transmission spectrum of our planet, obtained during a lunar eclipse, is now reported, with implications for the search to find analogues of Earth.

  • Mutations in LSM11 and RNU7-1, which encode components of the replication-dependent histone pre-mRNA–processing complex, cause an autoinflammatory syndrome due to enhanced interferon signaling mediated by the cGAS–STING pathway, showing an essential role for nuclear histones in suppressing the immunogenicity of self-DNA.

Here the authors analyse 111 TSC-associated tissues for TSC1/TSC2 status, DNA mutations, copy number aberrations, differential gene expression and DNA methylation patterns providing a comprehensive genomic landscape.

  • There is high prevalence of whole genome duplication (WGD) in high grade serous ovarian cancer. Here, the authors compare tumours with and without WGD and find that those that acquired WGD early during tumour evolution are associated with worse survival and have the lowest expression of MHC-II.

  • Trypanosomes evade the immune response through antigenic variation of a surface coat containing variant surface glycoproteins (VSG). They also express invariant surface glycoproteins (ISGs), which are less well understood. Here, Macleod et al. show that ISG65 of T. brucei is a receptor for complement component 3. They provide the crystal structure of T. brucei ISG65 in complex with complement C3d and show evidence that ISG65 is involved in reducing trypanosome susceptibility to C3-mediated clearance in vivo.

  • HNF1B is overexpressed in the clear cell subtype and epigenetically silenced in the serous subtype of ovarian cancer. Pearce and colleagues now show that genetic variants in HNF1B are differentially associated with risks of developing these two cancer subtypes, possibly through an epigenetic mechanism.

  • Myosin Va is a two-headed molecular motor that transports cargo inside cells by moving along actin filaments. The trailing head detaches and swings 72 nm forward to bind to a new leading position. During the processive movement at least one of the heads remain bound to actin. This report visualizes the movement of a fluorescently-labelled myosin Va molecule while simultaneously observing the binding and dissociation of a fluorescent ATP analogue. This is the first direct demonstration of nucleotide binding to and movement of myosin V motors during stepping.
