Caspase 5c Amplifies Wnt via APC Cleavage to Promote Intestinal Homeostasis

[Nature] Scientists showed that caspase 5 (CASP5) is restricted to the human intestinal epithelium and manifests as three isoforms—CASP5A, CASP5B and CASP5C—among which CASP5C uniquely promotes Wnt signalling, which is essential for epithelial development and regeneration

TGM2-Mediated Serotonylation of GPX4 Confers Ferroptosis Resistance to Promote Gastric Tumorigenesis

[Cell Discovery] Using untargeted plasma metabolomics, researchers revealed that the level of serotonin (5-HT) is significantly elevated in gastric cancer (GC) patients. Functionally, 5-HT treatment dramatically promoted GC cell proliferation and tumor growth in a dose-dependent manner.

NOD2 Drives Regenerative Fetal-Like Reprogramming in the Intestinal Epithelium

[Proceedings of the National Academy of Sciences of the United States of America] Using irradiation injury as a model for small intestinal epithelium injury and repair, scientists found that the intestinal microbiota accelerated epithelial restitution by amplifying a repair-associated inflammatory response that promoted the emergence of fetal-like intestinal epithelial cells, marked by Ly6a and Clu.

RUNX2 Drives Adenoma-to-Carcinoma Transition in Colon Cancer

[Cell Death & Disease] Single-cell RNA sequencing revealed that CD8+ exhausted T cells were significantly enriched in adenoma and carcinoma tissues compared to adjacent normal tissues.

METTL3-Mediated m6a Modification of lncRNA MALAT1 Promotes Colorectal Cancer Progression by Activating the NF-κB Signaling Pathway

[Journal of Translational Medicine] Investigators elucidated the METTL3-N6-methyladenosine (m6A)-MALAT1-NF-κB regulatory axis in colorectal cancer, advancing the understanding of epigenetic mechanisms in cancer progression.

Aspartate Transporter SLC1A3 Promotes Colorectal Cancer via MDM2-P53 Pathway and M2 Macrophage Polarization

[Cancer Science] Researchers found that solute carrier family 1 member 3 (SLC1A3) is significantly overexpressed in colorectal cancer tissues compared to adjacent normal tissues, and elevated SLC1A3 expression is associated with poor prognosis.

SAC Regulates Glutathione Metabolism via the Keap1/Nrf2/GPX4 Signaling Pathway to Inhibit Ferroptosis and Alleviate Ulcerative Colitis

[Scientific Reports] Scientists investigated the molecular mechanism by which sulfurized garlic (SAC) inhibits ferroptosis through targeting Keap1/Nrf2/GPX4 signaling pathway, thereby restoring intestinal epithelial cell barrier function and alleviating ulcerative colitis.

The Role of Alternative Splicing in Gastric Cancer

[Biology Direct] The authors summarize the current knowledge of alternative splicing (AS) in gastric cancer (GC). Accumulating evidence shows that aberrant AS contributes to the oncogenesis, progression, invasion, metastasis, and drug resistance of GC.

The AGA Research Foundation Awards $2.9 Million in Digestive Health Research Funding

[American Gastroenterological Association] The American Gastroenterological Association (AGA) announced the selection of 84 recipients to receive $2.9 million in research funding through the annual AGA Research Foundation Awards Program.

Accelerating Leigh Syndrome Drug Discovery through Deep Learning Screening in Brain Organoids

[Nature Communications] Researchers highlighted azoles as promising candidates for Leigh and demonstrate the potential of combining in silico screens with human brain organoids as new approach methodologies

Retinoic Acid Drives Cell Fate Specification, Maturation, and Retinal Regionality in Human Retinal Organoids

[Nature Communications] Scientists showed that temporal and dosage-dependant modulation of retinoic acid during human retinal organoid differentiation induces distinct changes in retinal cell abundance, maturation, and organisation.

Patient-Derived Pediatric Brain Tumor Orthotopic Xenografts and Tumor Organoids Faithfully Recapitulate Primary Tumors

[Science Advances] Investigators described the establishment of tumor organoid (TO) and TO xenografts from patient-derived orthotopic xenografts of medulloblastoma, embryonal tumor with multilayer rosettes, and atypical teratoid rhabdoid tumors.
