Proteogenomic Characterization Reveals Metabolic Vulnerabilities and Aberrant Phosphorylation in Colorectal Metastasis to Liver

open access: yesAdvanced Science, EarlyView.
This study provides a multi‐omics landscape of treatment‐naïve colorectal liver metastasis and reveals dysregulated molecules and cellular pathways. SHMT1 and NDRG1 Ser330 phosphorylation are demonstrated to display crucial roles in tumorigenesis and liver metastasis. Two proteomics subtypes (metabolism and RNA function) with distinct clinical outcomes

CypA Mediates Non‐Small Cell Lung Cancer Chemoresistance by Attenuating Ferroptosis via Stabilizing SLC7A11

open access: yesAdvanced Science, EarlyView.
Summary diagram for the role of CypA in chemoresistance in non‐small cell lung cancer (NSCLC). CypA is overexpressed in chemoresistance NSCLC and drives therapeutic evasion by competitively binding to the K37 site of SLC7A11, thereby blocking TRIM3 mediated K11‐linked ubiquitination and proteasomal degradation, ultimately inhibiting lipid peroxidation ...

Targeting WEE1 in ARID1A/TP53 Concurrent Mutant Colorectal Cancer by Exploiting R‐Loop Accumulation and DNA Repair Deficiencies

open access: yesAdvanced Science, EarlyView.
ARID1A, a SWI/SNF complex component, is frequently mutated in colorectal cancer (CRC). CRC with ARID1A/TP53 concurrent mutations shows marked sensitivity to WEE1 inhibition. ARID1A loss induces R‐loop‐mediated replication stress, impairs ATF3 transcription, and amplifies WEE1i‐induced DNA damage, suggesting a promising therapeutic vulnerability ...

Efferocytosis‐Driven Polyamine Metabolism in Macrophages Enhances Cancer Stem Cell Enrichment after Chemotherapy in Ovarian Cancer

open access: yesAdvanced Science, EarlyView.
Chemotherapy‐induced efferocytosis drives ovarian cancer stem cell enrichment. By engulfing apoptotic cancer cells, macrophages upregulate ODC1 and produce putrescine, which elevates osteopontin (OPN) expression. Secreted OPN then activates the CD44 receptor on cancer cells, promoting stemness and chemoresistance.

Folic Acid‐Modified Ginger‐Derived Exosome‐Like Nanoparticles Co‐Delivering Sunitinib Suppress Renal Cell Carcinoma via PI3K‐Akt Pathway Inhibition, P‐gp Downregulation, and Macrophage Reprogramming

open access: yesAdvanced Science, EarlyView.
FPD‐GELNs co‐deliver Su and bioactive components. This active‐passive dual‐targeting strategy suppresses the progression of RCC through the following mechanisms: 1) inhibition of the PI3K‐Akt signaling pathway; 2) downregulation of ABCB1/P‐gp to enhance the chemosensitivity of RCC to Su; and 3) reprogramming of macrophages toward M1 polarization and ...
