| Open AccessBlunted ventral striatal responses to anticipated rewards foreshadow problematic drug use in novelty-seeking adolescents
Some adolescents seek novelty, but it is unknown whether the brain circuits underlying this behaviour can be used to predict later, problematic behaviour. Here, authors show that diminished ventral striatal and prefrontal activity in response to anticipated rewards at age 14 in these individuals predicts problematic drug use at age 16.

| Open AccessMolecular dissection of colorectal cancer in pre-clinical models identifies biomarkers predicting sensitivity to EGFR inhibitors
The heterogeneity of colorectal cancer has important clinical and therapeutic implications. Here the authors analysed the responses of a large biobank of organoids and xenografts derived from colorectal patients to a panel of clinically relevant therapeutic agents to identify genes signatures associated with drug response.

| Open AccessMonitoring peripheral nerve degeneration in ALS by label-free stimulated Raman scattering imaging
Sensitive and label-free imaging methods to visualize nerve degeneration are currently lacking. Here authors show that stimulated Raman scattering (SRS) microscopy can be used to monitor peripheral nerve degeneration in mouse models of amyotrophic lateral sclerosis (ALS) and in postmortem tissue from ALS patients.

| 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 AccessMAP3K8/TPL-2/COT is a potential predictive marker for MEK inhibitor treatment in high-grade serous ovarian carcinomas
The identification of pharmaceutically targetable biomarkers is essential for improving therapeutic options for cancer patients. In this study, the authors identify MAP3K8 as a potential predictive marker for MEK inhibitor treatment in patients with aggressive ovarian cancer.

| Open AccessImmunological biomarkers predict HIV-1 viral rebound after treatment interruption
In some HIV-1-infected individuals, viraemia remains undetectable after antiretroviral treatment, but which of these patients will experience viral rebound is difficult to predict. Here the authors show that T cell exhaustion markers before treatment are predictive of shorter time to viral rebound.

Low MITF/AXL ratio predicts early resistance to multiple targeted drugs in melanoma
Increased expression of MITF transcription factor is thought to promote melanoma progression and kinase inhibitor resistance. Here Muller et al. show that MITF loss is also common in melanomas and confers kinase inhibitor resistance due to upregulation of AXL and other receptor tyrosine kinases.

Angiotensin II plasma levels are linked to disease severity and predict fatal outcomes in H7N9-infected patients
An avian influenza H7N9 virus causes severe human disease, including acute and often lethal respiratory failure. Here, the authors report that plasma levels of angiotensin II, a regulatory peptide of the renin–angiotensin system, are associated with disease severity and fatal outcome in infected patients.
