Lactylation Enhances the Activity of Lactate Dehydrogenase A and Promotes the Chemoresistance to Cisplatin Through Facilitating DNA Nonhomologous End Junction in Lung Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
Lactylation, linked to glycolysis, is poorly understood in regulation. It is found that LDHA is lactylated at Lys81/Lys318 by AARS1, boosting its activity and cellular lactylation via positive feedback in LUAD. Lactylation regulates NHEJ‐related proteins; their delactylation impairs NHEJ and increases cisplatin sensitivity, offering anticancer insights.

ACSL5 Regulates Glucose Metabolism and Chemotherapy Sensitivity in Colorectal Cancer Cells under Glutamine Deficiency

open access: yesAdvanced Science, EarlyView.
Glutamine deprivation triggers ACSL5 upregulation in tumor cells, sustaining their viability via dual metabolic rewiring programs. ACSL5 enhances glycolysis by relieving p53's inhibition of PGAM1 while also sustaining mitochondrial respiration and TCA cycle flux through promoting IDH2 dimerization.

Characterizing Stage‐Specific Cellular Dynamics and Microenvironmental Remodeling in Lung Adenocarcinoma by Single‐Cell RNA Sequencing

open access: yesAdvanced Science, EarlyView.
This study integrated early‐stage patient specimens with publicly available datasets encompassing non‐malignant lung tissues and advanced‐stage LUAD through single‐cell sequencing, revealing a dynamically remodeled tumor microenvironment characterized by a hypoxia‐adapted malignant subset (C5), immunosuppressive LGMN+ macrophages, STAT1‐driven ...

LMO7 Suppresses Tumor‐Associated Macrophage Phagocytosis of Tumor Cells Through Degradation of LRP1

open access: yesAdvanced Science, EarlyView.
LMO7 in tumor‐associated macrophages suppresses phagocytosis of tumor cells and limits cytotoxic T lymphocytes infiltration, fostering tumor progression. Mechanistically, LMO7 mediates the ubiquitination and degradation of the phagocytic receptor LRP1, impairing its ability to engulf tumor cells and driving macrophages toward an antitumor phenotype ...

KRAS Withdrawal in Cholangiocarcinoma Leads to Immune Infiltration and Tumor Regression

open access: yesAdvanced Science, EarlyView.
Cholangiocarcinoma (CCA) driven by oncogenic KRAS depends on its continuous activation for tumor maintenance. Using a conditional KRAS model, the authors show that turning off KRAS triggers rapid tumor regression accompanied by immune cell infiltration and cytokine release. The findings uncover a KRAS–senescence–immune signaling axis and highlight KRAS
