  eLife Assessment

  This valuable study demonstrates that the GSK-3 inhibitor AZD2858 inhibits the formation of TOPBP1 condensates and hence DNA damage responses in colorectal cancer cells. The evidence supporting the claims of the authors is convincing, although uncovering how this drug blocks bio-condensate formation would have strengthened the study. The work will be of interest to cancer researchers searching for synergistic drug combination strategies.

  This study presents a useful finding for the ferroptosis-mediated tumor microenvironment (TME) in triple-negative breast cancer (TNBC) using public single-cell RNA sequencing (scRNA-seq) and bulk RNA sequencing data. The data were collected and analyzed using solid and validated methodology and can be used as a starting point for functional studies of TME in TNBC. The work will be of interest to medical biologists working in the field of TNBC.

  eLife Assessment

  The authors present an important set of data implicating ETFDH as an epigenetically suppressed gene in cancer with tumor suppressive functions. The evidence is solid, with the authors demonstrating that ETFDH suppression results in accumulation of amino acids that impact metabolism via hyperactive mTORC1.

  eLife Assessment

  In this valuable study, the authors demonstrate that TCF7L2 plays a role in the pathogenesis of cachexia in a mouse model of GI cancer. The results are solid, although future studies will need further mechanistic analyses. These data will be interesting to cancer biologists, especially those trying to understand late-stage complications such as cachexia and wasting, a major cause of cancer morbidity and mortality.

  eLife Assessment

  This useful study explores the role of RAP2A in asymmetric cell division (ACD) regulation in glioblastoma stem cells (GSCs), drawing parallels to Drosophila ACD mechanisms and proposing that an imbalance toward symmetric divisions drives tumor progression. While findings on RAP2A's role in GSC expansion are promising, the study is nevertheless incomplete. Limitations include the lack of comprehensive GBM subtype analysis, insufficient mechanistic validation, and reliance on neurosphere models without in vivo confirmation. Addressing those gaps is necessary to substantiate the study's claims.
