T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

POU2F1 Promotes Chemoresistance in Colorectal Cancer Cells via Attenuates the MDR2 Degradation Mediated by PPP1R11 Lactylation

Advanced Science, EarlyView.
Schematic diagram of our study showing that highly expressed POU2F1 in colorectal cancer (CRC) can directly accelerate the cytosolic lactate export to decrease PPP1R11 lactylation at K59, thereby attenuating the E3 ligase enzyme activity and protein stability of PPP1R11, which inhibits the ubiquitination of MDR2 at K413 and K538 but increases the ...

Repeated Disuse Atrophy Imprints a Molecular Memory in Skeletal Muscle: Transcriptional Resilience in Young Adults and Susceptibility in Aged Muscle

Advanced Science, EarlyView.
Repeated disuse imprints a molecular memory in skeletal muscle, conferring transcriptional resilience in young adults but exaggerated susceptibility in aged muscle, driven by epigenetic regulation of aerobic metabolism, mitochondrial and NAD+ pathways.

Interaction between cellular retinoic acid-binding protein II and histone hypoacetylation in renal cell carcinoma [PDF]

, 2008
Renal cell carcinoma is a rare but serious malignancy. Since a reduction in the level of retinoic acid receptor beta 2 (RARbeta2) expression in cancer cells due in part to histone hypoacetylation which is controlled by histone deacetylase (HD), the study

KMT2C Loss Promotes NF2‐Wildtype Meningioma Progression and Ferroptosis Sensitivity via Epigenetic Repression of Hippo Signaling

Advanced Science, EarlyView.
In NF2–wild‐type meningiomas, loss of the epigenetic regulator KMT2C suppresses NF2 transcription and inactivates Hippo signaling, driving tumor progression and increasing ferroptosis sensitivity. Restoration of histone acetylation reverses these effects and inhibits tumor growth, identifying KMT2C as a key regulator linking epigenetic control, NF2 ...

SIRT1 Prevents Ferroptosis in Corneal Epithelial Cells by Enhancing HIF1α Protein Stability in Dry Eye Disease

Advanced Science, EarlyView.
Hyperosmotic stress drives ferroptosis in corneal epithelium via SIRT1 downregulation. This work demonstrates that SIRT1 activation stabilizes HIF1α, which transcriptionally upregulates GPX4 to inhibit lipid peroxidation and cell death. The identified SIRT1/HIF1α/GPX4 axis reveals a novel defense mechanism and potential therapy for dry eye disease ...

SATB2 Mediates H3K9 Delactylation by Recruiting HDAC3 to Repress LCN2 and Inhibit Lung Tumor Growth and Metastasis

Advanced Science, EarlyView.
This study highlights the capacity for tumor suppressor SATB2 to recruit HDAC3 and catalyze histone H3K9 delactylation, thereby repress transcription of the oncogene LCN2. This novel epigenetic‐metabolic axis inhibits the growth and metastasis of non‐small cell lung cancer, delineating a new mechanistic pathway with potential therapeutic relevance ...

Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

Advanced Science, EarlyView.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Post‐Translational Regulation of CD8+ T Cell Fate and Dysfunction in Tumor Immunity

Advanced Science, EarlyView.
This review delineates how post‐translational modifications (PTMs) function as a central regulatory interface governing CD8+ T cell activation, differentiation, persistence, and exhaustion in antitumor immunity. By integrating antigenic, metabolic, and microenvironmental cues, diverse PTM programs coordinate transcriptional and chromatin states that ...
