  Evaluation Summary:

  This paper will be of broad interest to many fields, including drug discovery, cancer biology, and structure biology. It makes a significant advance in understanding the mechanism of action of hormone therapies for breast cancer, and how resistance driving mutations alter drug responses. The structural biology data has clear potential for strong impact though some additional analysis might be needed.

  Evaluation Summary:

  This manuscript addresses outstanding questions about the molecular mechanisms by which the two types of arginine-methylating enzymes affect the processing and fate of transcripts in mammalian cells. This work makes important inroads into these questions, uncovering an inverse effect of the two types of enzymes on intron retention during post-transcriptional splicing, linking the effects to specific target proteins. With better support of some key claims , the paper will provide a lot of new information about the functional consequences of asymmetric and symmetric demethylation.

Crosstalk with keratinocytes causes GNAQ oncogene specificity in melanoma

• Curated by eLife

  Evaluation Summary:

  In this manuscript, the authors study the discrepancy between the frequency of mutations in Gq alpha subunit (GNAQ and its paralogue GNA11) in uveal vs cutaneous melanoma. They hypothesize that the restriction of GNAQ and GNA11 mutations to non-epithelial melanomas is due to epidermal factors, which convert the impact of GNAQ Q209L mutation from being oncogenic to being inhibitory to melanocyte survival and proliferation, and reduce the maintenance, rather than the establishment of interfollicular epithelial melanocytes. This work provides new insights into the poorly understood difference in mutation frequency in different melanoma types.

  Evaluation Summary:

  Truncated splice variants of the androgen receptor (AR) lacking a ligand-binding domain are thought to contribute to therapeutic resistance to antiandrogens in advanced prostate cancer. In this manuscript, the authors show that AR-V7, the most well-studied such truncated variant, displays a different mechanism of nuclear targeting and interaction with chromatin compared to the full-length AR. This work provides new insights into how AR-V7 may contribute to the pathology of Castrate-Resistant Prostate Cancer and will be of interest to researchers trying to improve prostate cancer therapies.

  Evaluation Summary:

  This work develops a multistage/component mathematical model to analyze advanced colorectal adenomas and the impact that aspirin therapy has on adenoma formation rates. This study will be interesting to the cancer evolution community and in particular those interested in colorectal cancer incidence. While the model is mainly focused on aspirin chemoprevention, the model could be adapted to test other putative preventative agents, and thus could have a broad impact.

  Evaluation Summary:

  This study identifies ZHX2 as an oncogenic factor in triple negative breast cancer (TNBC), which interferes with hypoxia-related regulators and accounts for cancer aggressiveness and poor prognosis. The authors show that ZHX2 interacts with HIF1α and increases the expression of its downstream targets and identify ZHX2 residues critical for regulating its activity. This work provides a potential novel target in TNBC treatment and would be of interest to cancer biology researchers.

  Evaluation Summary:

  This paper investigating specific metabolic dependencies of pancreatic cancer cells growing in vitro and in vivo will be of interest to scientists in the field of cancer metabolism. The data reveal that cancer-associated stromal cells can play an important role supporting the redox state of cancer cells cultured in vitro, but at present the data do not support the conclusion that this mechanism controls the metabolic resilience of cancer cells growing in vivo and alternate hypotheses remain to be addressed.
