The discovery of synthetic lethality between BRCA mutations and PARP inhibitors ranks has led to major advances in the treatment of BRCA-mutated cancers. Mutations in BRCA1 and BRCA2 can leave cells with a deficiency in homologous repair (HR). And that deficiency can make them vulnerable to PARP inhibitors, which block alternate DNA repair pathways, as well as platinum-based treatment, which induces DNA mutations that BRCA-deficient cells are unable to cope with.
Using advanced intravital microscopy to visualize immune cell movement within the tissues, investigators at the Peter Doherty Institute for Infection and Immunity, Melbourne have discovered that the neurotransmitter noradrenaline produced by the sympathetic nervous system causes a dramatic paralysis of immune cell movement.
Researchers have gained new insights into what makes for transplantable livers – and what doesn’t. In a clinical trial of 12 livers, a team from Massachusetts General Hospital showed that both livers with high fat content and those without could be viable for transplantation.

Twenty years after the first, exclusively white human genomes were fully sequenced, science finds itself in the same position as the rest of society: with the uncomfortable realization that old inequalities are often morphing, rather than disappearing. Vocal racists – scientists of the stripe of a James Watson – are by no means a thing of the past. But they are only the tip of the iceberg.

A study led by Chinese radiologists at Peking University in Beijing has shown that positron emission tomography imaging of intercellular adhesion molecule-1 (ICAM-1) expression is a predictor for the abscopal effect, whereby nonirradiated cancers respond to radiotherapy.
