Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

open access: yesAdvanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

Disruption of ARID1B Recruitment to the Nuclear Pore Complex as a New Anticancer Therapeutic Strategy

open access: yesAdvanced Science, EarlyView.
This study identifies ARID1B as a chromatin‐bound driver of tumor growth in TNBC. ARID1B impairs ARID1A function and directly activates oncogenic programs through SWI/SNF remodeling. Its nuclear localization, mediated by the KPNA2–KPNB1–RANBP2 import machinery, is essential for its tumor‐promoting activity.

A High‐Fidelity RNA‐Targeting Cas13X Downregulates Connexin43 in Macroglia: A Novel Neuroprotective Strategy for Glaucoma

open access: yesAdvanced Science, EarlyView.
This study highlights the role of connexin43 (Cx43) in mediating glia activation and neuroinflammation in glaucoma. Using Cx43 knockout mice, it is shown that macroglial cells‐derived Cx43 modulates microglial activation, proliferation, migration, and polarization.

POLE Deficiency Exacerbates Diesel Engine Exhaust‐Induced Genomic Instability and Malignant Transformation of Bronchial Epithelial Cells

open access: yesAdvanced Science, EarlyView.
This study establishes a diesel engine exhaust (DEE)‐induced malignant transformation model in bronchial epithelial cells. Whole genome sequencing(WGS) and RNA‐seq reveal DEE‐induced mutational signatures and gene expression profiles. Mechanistically, DEEaffect polymerase epsilon (POLE) and mismatch repair, driving genomic instability and promoting ...

LEDGF Binds H3R17me2a Promoting De Novo Nucleotide Biosynthesis in SETD2 Mutant Clear Cell Renal Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
In SETD2‐mutant ccRCC, the original LEDGF recognition of the H3K36me3 regulatory axis no longer exists. LEDGF interacts with CARM1‐dependent H3R17me2a regulating the transcription of key enzymes in the de novo synthesis pathway. The abnormally elevated LEDGF leads to the accumulation of purine nucleotides in SETD2‐mutant ccRCC, thereby satisfying the ...

Microphysiological Uremia Model Reveals Biophysical Potentiators of Vascular Dysfunction

open access: yesAdvanced Science, EarlyView.
A microfluidic platform of engineered blood vessels is developed to study the role of mechanical forces in immune cell adhesion and extravasation in uremic microenvironments. Elevated pressure increases monocyte activity, with ICAM‐1 as a key driver. Matrix density influences monocyte phenotypes, but the uremic environment consistently promoted a pro ...

Pyruvate Carboxylase in Macrophages Aggravates Atherosclerosis by Regulating Metabolism Reprogramming to Promote Inflammatory Responses Through the Hypoxia‐Inducible Factor‐1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
This study investigates the role of macrophage pyruvate carboxylase (PC) in atherosclerosis (AS) demonstrating that PC upregulation in macrophages promotes metabolism reprogramming to enhance inflammatory responses via the HIF‐1 signaling pathway.

Localized Delivery of the mRNAs Encoding CD47 Inhibitor and Interleukins 12, 15, and 21 Elicits Robust Antitumor Immunity

open access: yesAdvanced Science, EarlyView.
The co‐delivery of mRNAs encoding a CD47 inhibitor and a cytokine cocktail (interleukins 12, 15, and 21) via lipid nanoparticles enables effective localized immunotherapy. This strategy not only suppresses tumor progression but also enhances type 1 conventional dendritic cell (cDC1) differentiation and activates CD8+ T cells, thereby inducing robust ...

Discovery of Natural Compound α‐Hederin via Large‐Scale Screening as a Targeted JAK/STAT3 Inhibitor for Ovarian Cancer Therapy

open access: yesAdvanced Science, EarlyView.
This study identifies α‐Hederin as a potent dual JAK1/JAK2 inhibitor that blocks STAT3 activation in ovarian cancer. By disrupting STAT3‐driven transcriptional programs, α‐Hederin suppresses tumor proliferation, invasion, and EMT, while enhancing cisplatin efficacy and overcoming chemoresistance.
