A cell-free reaction that reconstitutes the selective sorting of a miRNA into exosomes reveals an RNA-binding protein, YBX1, as a critical sorting factor.
The PPARγ protein acts in macrophages to inhibit breast cancer progression and mediate the anti-tumor effects of rosiglitazone by suppressing Gpr132 – a pro-tumor and pro-inflammatory factor in macrophages.
A new technique for biodistribution and targeted uptake studies of nanoparticle imaging agents is demonstrated and used to achieve levels of detail that are inaccessible through existing methods.
The protein IFI6 regulates DNA replication via the transcription factor E2F2, which is necessary for transformation and growth of melanomas induced by the NRASQ61K mutant oncogene product.

Loss of function of the selective autophagy adaptor protein Alfy/Wdfy3 leads to profound wiring defects from the forebrain through to the spinal cord, highlighting the growing importance for macroautophagy in the developing brain.
Cell biological, biochemical and structural studies reveal the mechanistic roles of two new mitochondrial iron-sulfur protein assembly factors, explaining the patho-biochemical defects of affected patients.

Epstein-Barr virus controls B-cell growth and survival through large-scale reorganization of the enhancers of the MYC and BCL2L11 genes, and may promote MYC translocations as a result.
Building on previous work (Booth et al, 2014), we show how two mitotic phosphatases are formed, how they are regulated by opposing kinases during the cell cycle and reveal a novel opportunity for the development of cancer therapeutics.

Three months treatment with the drug rapamycin increases lifespan, alters cancer prevalence, remodels the microbiome, and improves functional measures of health in middle aged mice in a dose- and sex-dependent manner.
