HPD is an m6A Methyltransferase that Protects Colorectal Cancer Cells from Ferroptotic Cell Death by m6A Methylating SLC7A11/GPX4

open access: yesAdvanced Science, EarlyView.
This study reveals that the tyrosine metabolic enzyme HPD functions as a previously uncharacterized, METTL3‐independent m6A methyltransferase. It promotes colorectal tumor progression by coordinately regulating the SLC7A11/GPX4 axis to suppress ferroptosis.

The Tumor‐to‐Endothelial Transfer of FTO Promotes Vascular Remodeling and Metastasis in Nasopharyngeal Carcinoma

open access: yesAdvanced Science, EarlyView.
Integrated omics analysis of matched primary and liver metastatic NPC tumors reveals a unique NOTCH1+ CSC subpopulation exhibiting enhanced stemness properties and tumorigenic capacity. With in vitro and in vivo assays, exosomal transfer of tumor‐derived FTO from NOTCH1+ cells to the endothelium promotes vascular permeability and metastatic potential ...

Clinofibrate Disrupts the SNORA80B/YTHDC1‐Driven M6A Modification to Suppress Cholesterol Metabolism and Cisplatin Resistance in ESCC

open access: yesAdvanced Science, EarlyView.
This study uncovers a non‐canonical role of SNORA80B in ESCC, showing it mediates AR‐driven metabolic reprogramming via N⁶‐methyladenosine (m6A) methylation. By binding YTHDC1, SNORA80B stabilizes cholesterol‐metabolic enzyme mRNAs and promotes tumor progression. The FDA‐approved drug clinofibrate inhibits SNORA80B by disrupting cholesterol homeostasis,

Lactylation‐Driven YTHDC1 Alleviates MASLD by Suppressing PTPN22‐Mediated Dephosphorylation of NLRP3

open access: yesAdvanced Science, EarlyView.
In MASLD, YTHDC1 undergoes increased lactylation and ubiquitination, reducing its expression. AARS1 mediates lactylation at lysine 565, while disrupted binding to LDHA further promotes lactylation, suppressing YTHDC1. This downregulation enhances PTPN22 mRNA stability, leading to NLRP3 dephosphorylation and activation, which exacerbates inflammation ...

Correlative Imaging Platform Linking Taste Cell Function to Molecular Identity

open access: yesAdvanced Science, EarlyView.
A correlative imaging platform is developed to study how individual taste cells respond to different taste qualities. By linking cellular activity with molecular identity and environmental context, dual‐tuned taste cells capable of detecting both sweet and umami stimuli are identified.

Replacing Helper Lipids With Cationic Lipids Enhances mRNA Lipid Nanoparticles Stability in Solution

open access: yesAdvanced Science, EarlyView.
Partial Replacement of phospholipid lipid by cationic lipid improves storage stability of commercial mRNA LNPs by stabilizing their internal microstructure. Abstract Messenger RNA lipid nanoparticles (mRNA‐LNPs) have achieved remarkable success in clinical vaccination efforts to curb the COVID‐19 pandemic, and have attracted tremendous interest from ...

Carbon Monoxide Nanomodulator Reverses Ischemia‐Reperfusion Injury in Stroke: A Novel Dual‐Channel Therapy Mode of Co‐driving Neuroprotection and Neurogenesis

open access: yesAdvanced Science, EarlyView.
This work develops a biomimetic and reactive oxygen species‐activated carbon monoxide (CO) nanogenerator to penetrate blood‐brain barrier, arrive in stroke‐affected regions, and release CO in a controlled manner for an innovative dual‐channel therapy strategy via co‐driving neuroprotection and neurogenesis.

CD27 and ICOS as Targets of PD‐1/PD‐L1 Signaling to Regulate Resident Memory CD8+ T‐Cell‐Mediated Pulmonary Protection and Pathology

open access: yesAdvanced Science, EarlyView.
Here it is revealed that the costimulatory receptors CD27 and ICOS are essential for the long‐term maintenance of PD‐1high CD8+ TRM cells following influenza infection. PD‐L1 blockade enhances the proliferation and activation of these cells through Nur77 activation downstream of the CD27/ICOS signaling axis, thereby boosting host immunity against ...

EST analysis of gene expression in early cleavage-stage sea urchin embryos [PDF]

open access: yes, 1999
A set of 956 expressed sequence tags derived from 7-hour (mid-cleavage) sea urchin embryos was analyzed to assess biosynthetic functions and to illuminate the structure of the message population at this stage.
