    Defects in the homologous recombination repair of DNA can result in gene mutation and cancer. In this study, Peng et al.identify a gene signature associated with homologous recombination repair deficiency and show that this can be used both to predict repair defects and clinical outcome in cancer patients.

    Renin cells have traditionally been associated with the kidney where they regulate blood pressure and fluid electrolyte homeostasis. In this study, Belyea et al.describe a renin progenitor in the bone marrow that gives rise to B-cell leukaemia when RBP-J, the final effector of the Notch pathway, is deleted.

    Many studies provide evidence of genes that are associated with cancer prognosis but a global view of these genes is lacking. Using data from ‘The Cancer Genome Atlas’, Yang et al.investigate the network properties of prognostic genes and show that these genes tend to be within highly interconnected groups but not the most connected nodes in the gene co-expression network.

    R-spondin 2 has an important role in development but its function in cancer has not been described. In this study, Wu et al. demonstrate that R-spondin 2 is decreased in expression in colorectal cancer and this is associated with promoter methylation and inhibition of Wnt signalling.

    A role for the serpin maspin has been described in both development and cancer. In this study, the authors demonstrate that maspin knockout mice develop normally and that maspin does not function as a tumour suppressor, suggesting that another gene at the maspin locus may be responsible for this activity.

    Non-coding RNAs have recently emerged as crucial regulators of gene expression. Here Rutnam et al.identify a pseudogene complementary to the 3′-UTR of the TUSC2 tumour suppressor that regulates TUSC2 levels by acting as a decoy for endogenous microRNAs and thereby inhibits tumorigenesis.

    The majority of ovarian granulosa tumours harbour the C134W mutation in FOXL2 but the mechanism of tumorigenesis is largely unknown. Here, Kim et al. show that mutant FOXL2 is hyperphosphorylated by GSK3β, which targets the protein for degradation, and find that GSK3β inhibition represses the growth of ovarian granulosa cells.

    The Hippo tumour suppressor pathway is inactivated in many cancer types, but how this occurs is unclear. Here, the authors show that integrin-linked kinase (ILK) has a role in inhibiting the Hippo pathway and pharmacological inhibition of ILK reduces the size of tumours in mice.
