Lactate Activates the HCAR1/β‐Arrestin2/PP2A Signaling Axis to Mediate STAT1/2 Dephosphorylation and Drive Osteosarcoma Progression

open access: yesAdvanced Science, EarlyView.
In the present study, it is found that in osteosarcoma, lactate‐activated HCAR1 promotes β‐arrestin 2 translocation from cytoplasm to nucleus. In the nucleus, β‐arrestin 2 recruits PP2A to the activated STAT1/2 dimers, mediating STAT1/2 dephosphorylation and inhibiting the transcription of downstream anti‐oncogenes to promote OS progression.

Development of a 3D Human Colon Model Along with Bioelectronics for the Induction and Monitoring of Diseases

open access: yesAdvanced Science, EarlyView.
We present a functional three‐dimensional in‐vivo‐mimicking human colon (3D‐IVM‐HC) model engineered via Freeform Reversible Embedding of Suspended Hydrogels bioprinting with gelatin methacrylate (GelMA)/alginate hydrogels. This 3D non‐animal model replicates crypt‐like architectures, epithelial polarization, and stromal–tumor interactions, showing ...

KLK1 as an Epithelial‐Specific Brake Inhibits Colorectal Tumorigenesis by Suppressing B1R‐Mediated Fibroblast Phenotypic Transition

open access: yesAdvanced Science, EarlyView.
KLK1 downregulation disrupts the intestinal mucosal barrier and impairs kallikrein‐kinin signaling, thereby reducing Lys‐des‐Arg9‐BK production. This enhances B1R activation on ADAMDEC1⁺ fibroblasts, promoting inflammation and extracellular matrix (ECM) remodeling. The resulting iCAFs promote colorectal cancer progression, highlighting a novel KLK1‐B1R

Novel Evolutionarily Conserved Oncogene COA4 is Driven by KRAS Mutant and Promotes Cancer Metastasis Through Dual Mitochondrial Metabolism‐Dependent and ‐Independent Mechanisms

open access: yesAdvanced Science, EarlyView.
In KRAS‐mutant tumors, KRAS transcriptionally upregulates COA4 via the PI3K/AKT/E2F1 axis, promoting metastasis. Mechanistically, COA4 enhances tumor cell migration through dual pathways: within mitochondria, it boosts oxidative phosphorylation; in the cytoplasm, it binds and activates CDC42 to stimulate pseudopodia formation.

Genetic and Functional Evidence Links Germline Biallelic Inactivating Variants in WWOX to Histological Mixed‐Type Thyroid Cancer

open access: yesAdvanced Science, EarlyView.
The role of germline WWOX loss‐of‐function variants in oncogenesis has remained poorly characterized. This study provides the first comprehensive genetic and functional evidence that such variants promote tumorigenesis through the disruption of multiple tumor‐suppressive mechanisms.
