  The authors of this important study investigate how telomere length regulates hTERT expression via non-telomeric binding of the telomere-associated protein TRF2. They conclusively show that TRF2 binding to long telomeres results in a reduction in its binding to the hTERT promoter, while short telomeres restore TRF2 binding in the hTERT promoter, recruiting repressor complexes like PRC2, and suppressing hTERT expression. There is convincing support for the claims and the findings should be of broad interest for cell biologists and those working in fields where telomeres alter function, such as cancer and aging.

  This work presents a useful resource combining scRNA-seq and spatial transcriptomics studies to map mouse pre-clinical models of colorectal cancer, identifying distinct cellular programs and microenvironments that could enhance patient stratification and therapeutic approaches in colorectal cancer. While the novelty of the biological findings remains limited and incompletely supported by the evidence provided in the manuscript, the data were collected and analyzed using a validated methodology that will be of interest to the community in future studies.

  This important study employs an optogenetics approach aimed at activating oncogene (KRASG12V) expression in a single somatic cell, with a focus on following the progression of activated cell to examine tumourigenesis probabilities under altered tissue environments. Although the description of the methodologies applied is incomplete, the authors propose a mechanism whereby reactivation of re-programming factors correlates with the increased likelihood of a mutant cell undergoing malignant transformation. This work will be of interest to developmental and cancer biologists, especially in relation to the genetic tools described.

  This work attempts to demonstrate an ATP-independent non-canonical role of proteasomal component PA28y in the promotion of oral squamous cell carcinoma growth, migration, and invasion. Although the authors have addressed some concerns, uncertainties regarding the PA28g-C1QBP direct interaction still exist. The overall findings of the manuscript are useful, but the validation evidence is incomplete.

  In this valuable study, Seidel et al. identify and characterize a novel subset of hepatocellular carcinoma patient-derived xenograft models defined by active Jagged 1-Notch2 signaling and a distinctive progenitor-like gene expression profile. Within the limitations of the PDX system they used, their methods are state-of-the-art, their data are strong and believable, and their conclusions are convincing. However, the ability to identify HCC patients that might respond is limited, and the mechanistic assessment downstream of JAG1/NOTCH2 is relatively descriptive. Some additional clarifications and experiments would strengthen the paper.

  This manuscript provides valuable mechanistic insight into NSCLC progression, both in terms of tumour metastasis and the development of chemoresistance. The authors draw upon a range of techniques and assays and the evidence shown is solid and has been strengthened by incorporation of suggestions by the two reviewers. The work presented will be of interest to cancer biologists and more broadly to those interested in NSCLC translational studies.
