  • Temporal multi-omic analysis of tissues from rats undergoing up to eight weeks of endurance exercise training reveals widespread shared, tissue-specific and sex-specific changes, including immune, metabolic, stress response and mitochondrial pathways.

  • The molecular alterations driving anti-androgen resistance in prostate cancer are unclear. Here, the authors show, using a network-based approach, that inhibition of the hexosamine biosynthetic pathway is necessary to develop resistance and that increasing the activity of the pathway enhances the anti-androgen response.

  • It is known that exercise influences many human traits, but not which tissues and genes are most important. This study connects transcriptome data collected across 15 tissues during exercise training in rats as part of the Molecular Transducers of Physical Activity Consortium with human data to identify traits with similar tissue specific gene expression signatures to exercise.

  • Metastasis is a fatal complication of prostate cancer, but its mechanisms remain largely unknown. In this report, the authors identify a signaling pathway commonly deregulated in human prostate cancer and describe how it can foster both primary growth and metastatic tumor progression. Epigenetic silencing of the RasGAP DAB2IP by EZH2 overexpression results in aberrant activation of Ras signaling, but also of NF-κB. These two events are mediated by different DAB2IP domains and have distinct roles in localized growth and distant dissemination.

  • Individuals with Down's syndrome are known to have a lower rate of certain solid cancers. Now, a mouse model with one extra copy of Dscr1, a gene located on chromosome 21, is shown to display decreased tumour growth; this is thought to be via suppression of angiogenesis mediated by decreasing the activity of the calcineurin pathway.
