Decay of Driver Mutations Shapes the Landscape of Intestinal Transformation

[Nature] The authors established that the presence of diverse priming events in the normal mouse intestinal epithelium can change the transformation and clonal-selection landscape, permitting the fixation of strong driver mutations in Apc and Ctnnb1 that are otherwise lost due to negative selection.

A Niche-Dependent Redox Rheostat Regulates Epithelial Stem Cell Fate

[Nature Communications] Scientists showed that cellular redox balance orchestrates niche factors with metabolic state to govern cell fate decisions.

Iron Homeostasis and Cell Clonality Drive Cancer-Associated Intestinal DNA Methylation Drift in Aging

[Nature Aging] By analyzing DNA methylation and gene expression data from healthy and cancerous human colon samples, investigators identified an aging and colon cancer-associated DNA methylation drift.

RNA-Binding Protein HnRNPU Regulates Proliferation and Ferroptosis in Colon Adenocarcinoma by Stabilizing the mRNA of System Xc−

[Experimental & Molecular Medicine] The authors identified increased heterogeneous nuclear ribonucleoprotein U (HnRNPU) expression in patients with colon adenocarcinoma, with higher levels correlating with poor patient survival.

TAF1 Acetyltransferase Promotes Colorectal Carcinoma Metastasis by Catalyzing β-hydroxybutyrylation of KCTD9

[Oncogene] Researchers identified that TATA-binding protein-associated factor-1 (TAF1), also as a lysine acetyltransferase, is frequently upregulated in colorectal cancer.

A GPER-PKA-Centrin Axis Regulates Centrosome Numbers and Centriole Integrity in Colon Cancer Cells

[Communications Biology] Scientists showed that protein Kinase A (PKA) is central to a signaling cascade involving the G protein-coupled estrogen receptor GPER1, which is essential for centrosome integrity in colon cancer cells.

Same Mutation, Different Fates: The Yin-Yang of BRAF-Driven Therapeutic Responses in Melanoma and Colorectal Cancer

[Biochimica Et Biophysica Acta-Reviews On Cancer] The authors dissect the “yin-yang” of BRAF as a therapeutic vulnerability in in melanoma and colorectal cancer and underscore the critical importance of tumor-specific context in precision oncology.

Camilla Engblom One of This Year’s Wallenberg Academy Fellows

[Karolinska Institute] One of the young researchers receiving Knut and Alice Wallenberg Foundation’s basic research grant this year is Camilla Engblom. She will use the funding to study a piece of the puzzle that could help develop more precise and personalized treatments for cancer and inflammatory bowel disease.

Gas Plasma-Induced Bacterial PAMP Release Promotes Skin Cancer Cell Death

[Cell Death & Disease] Researchers elucidated gas plasma-induced bacterial pathogen-associated molecular patterns (PAMP) release and their combination with direct gas plasma exposure in skin cancer cells in vitro.

The Syntenic Long Non-Coding RNA DANCR Is an Essential Regulator of Zebrafish Development and a Human Melanoma Oncogene

[PLoS Genetics] Scientists identified melanoma-associated lncRNAs predicted to be components of the MITF gene regulatory network in human melanoma that have positionally equivalent transcripts in zebrafish.

Exploiting Metabolic Adaptations to Overcome Dabrafenib Treatment Resistance in Melanoma Cells

[Molecular Oncology] The authors dissected signaling and mitochondrial alterations that characterize the transition from BRAF-specific inhibitors responsiveness to resistance in A375 melanoma cells.

GPX8 Is Transcriptionally Regulated by KLF16 and Promotes Osteosarcoma Progression

[Journal of Translational Medicine] Researchers demonstrated that glutathione peroxidase 8 (GPX8) is a critical oncogene in osteosarcoma progression and that its expression is regulated by kruppel‑like factor 16 (KLF16).
