  Evaluation Summary:

  Menjivar et al. identify a previously unrecognized role of myeloid cell Arginase1 (Arg1) activity in shaping the anti-tumor immune response in pancreatic ductal adenocarcinoma (PDAC). The proposed therapeutic combination is a new approach for pancreatic cancer, with an enhanced response to immune therapy upon arginase inhibition.

  Evaluation Summary:

  This study builds on previous observations of arginine depletion in the pancreatic tumor microenvironment, with the goal of developing and using a cell culture medium (TIFM) that better recapitulates nutrient levels in the TME. With this system, the authors identify arginine biosynthesis as an adaptation of pancreatic cancer cells to arginine starvation. This work reinforces a timely message that builds upon the push for optimizing and reformulating cell culture media, so as to improve fidelity, and better recapitulation of physiological/pathophysiological cellular behavior. The latter is in turn critical for translational and therapeutic applications. The work will be of interest to tumor biologists.

  Evaluation Summary:

  This paper provides insight into a potentially new genetically defined subset of prostate tumors driven by concurrent loss of two tumor suppressor genes. This study both validates previous findings and provides new data that is compelling overall. With some additional statistical and biochemical evidence to support the conclusions, the work would be of interest to cancer biologists studying molecular mechanisms of prostate cancer.

Theoretical analysis reveals a role for RAF conformational autoinhibition in paradoxical activation

1. Gaurav Mendiratta
2. Edward Stites

• Curated by eLife

  eLife assessment

  This important study uses mathematical modelling to demonstrate that conformational autoinhibition of the RAF kinase is an important feature of its paradoxical activation by pharmacological inhibitors. This part of the theoretical analysis is highly compelling but its extension to the investigation of how the binding of 14-3-3 adaptors additionally contributes to the paradoxical activation phenomenon is incomplete and would benefit from more rigorous experimental validation. With the experimental part addressing 14-3-3-dependent regulation strengthened or the 14-3-3 part completely removed, this paper would be of considerable interest to cell biologists and cancer biologists, ultimately paving the way for improved RAF therapeutics.

  Evaluation Summary:

  This manuscript shows that mutations in the gene encoding an enhancer chromatin-modifying enzyme MLL3 cooperate with Myc overexpression to drive hepatocellular carcinoma in mouse models. The authors identify Cyclin Dependent Kinase Inhibitor 2A (Cdkn2a) as a critical direct target gene of MLL3. Overall, the manuscript makes a compelling case that MLL3 is a hepatocellular carcinoma tumor suppressor that directly binds and activates the Cdkn2a locus. This study provides important insights for cancer biologists and those interested in specific epigenetic mechanisms that regulate liver cancer development. Editorial and some experimental suggestions were made to strengthen the work.

  Evaluation Summary:

  In this manuscript, the authors identify enhancer-associated (e)RNAs that are specifically associated with esophageal adenocarcinoma. Based on combining the data with analyses of patient gene expression data and epigenetic data from cell lines, they conclude that eRNAs are markers of enhancers relevant to the transition from Barrett's esophagus to cancer. This work provides new insights into the epigenetic alterations that occur in cancer progression, and it will be of interest to the cancer and epigenetics fields.
