| Open AccessReconciled rat and human metabolic networks for comparative toxicogenomics and biomarker predictions
The rat is a widely-used model for human biology, but we must be aware of metabolic differences. Here, the authors reconstruct the genome-scale metabolic network of the rat, and after reconciling it with an improved human metabolic model, demonstrate the power of the models to integrate toxicogenomics data, providing species-specific biomarker predictions in response to a panel of drugs.

| Open AccessBasal forebrain degeneration precedes and predicts the cortical spread of Alzheimer’s pathology
Whether Alzheimer’s disease originates in basal forebrain or entorhinal cortex remains highly debated. Here the authors use structural magnetic resonance data from a longitudinal sample of participants stratified by cerebrospinal biomarker and clinical diagnosis to show that tissue volume changes appear earlier in the basal forebrain than in the entorhinal cortex.

| Open AccessTranslation control during prolonged mTORC1 inhibition mediated by 4E-BP3
The eIF4E-binding proteins (4E-BPs) are critical repressors of cap-dependent translation via mTOR, a pathway frequently hyperactivated in cancer. Here the authors show that 4E-BP3 specifically mediates the cap-dependent translation repression and antiproliferative effects of prolonged pharmacological mTOR inhibition.

| Open AccessSingle-cell differences in matrix gene expression do not predict matrix deposition
Regenerative tissue engineering with mesenchymal stem cells is hampered by bulk methods of assessing differentiation status and a general assumption that expression of individual markers of stem cell differentiation correlate with functional capacity. Here the authors debunk this assumption by applying single-cell techniques to disassociate aggrecan mRNA abundance and matrix deposition.

| Open AccessCerebrospinal fluid-derived circulating tumour DNA better represents the genomic alterations of brain tumours than plasma
DNA circulating in the plasma of cancer patients carries features of the primary tumour, however such DNA is found in low levels in brain cancer patients. Here, the authors show that circulating tumour DNA can be detected in the cerebral spinal fluid of cancer patients and that this better recapitulates the primary tumour compared to DNA from the plasma.

| Open AccessSTAT3 regulated ARF expression suppresses prostate cancer metastasis
IL6-STAT3 signaling is activated in prostate cancer, however inhibiting this pathway has not lead to a survival advantage in patients. Here, Pencik et al.show that loss of the IL6-STAT3 axis in mice and humans leads to metastasis due to loss of ARF, unravelling STAT3 and ARF as potential prognostic markers in prostate cancer.

| Open AccessDesialylation is a mechanism of Fc-independent platelet clearance and a therapeutic target in immune thrombocytopenia
Immune thrombocytopenia (ITP) is caused by autoantibody-mediated platelet clearance, but refractoriness to current immunomodulatory therapies is common. Here the authors show that desialylated platelets can be cleared via hepatic Ashwell–Morell receptor, a process that can be attenuated by sialidase inhibitors, suggesting a new therapy for ITP.
