Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

open access: yesAdvanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

open access: yesAdvanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

PARPi Combining Nanoparticle LIN28B siRNA for the Management of Malignant Ascites

open access: yesAdvanced Science, EarlyView.
This study demonstrates that co‐inhibition of LIN28B and PARP using siLin28b/DSSP@lip‐PEG‐FA nanoparticles in combination with the PARP inhibitor BMN673 effectively suppresses the accumulation of malignant ascites associated with advanced cancers.

The Disordered Region of ASXL1 Acts as an Auto‐Regulator Through Condensation

open access: yesAdvanced Science, EarlyView.
ASXL1's long IDR encodes an electrostatic “basic platform + acidic brake” that autoregulates condensation. Truncation at a clinical hotspot lifts this brake, forming condensates that retarget BRD2, remodel local chromatin accessibility, and impair neutrophil maturation.

A Biomarker‐Driven Ovary–Endometrium Organ‐on‐a‐Chip Mimicking 3D Multicellular Complexity and Menstrual Cyclicity for Predicting Reproductive Toxicity

open access: yesAdvanced Science, EarlyView.
We present a dual‐organ, biomarker‐integrated ovaryendometrium organ‐on‐a‐chip that recapitulates 3D tissue complexity, menstrual cycle dynamics, and hormonal crosstalk. This platform enables real‐time, cell‐typespecific fluorescent readouts of reproductive toxicity using ANGPTL4 and SERPINB2 as early‐response reporters.

Novel Vascularized Human Liver Organoids for Modeling Alcohol‐Induced Liver Injury and Developing Hepatoprotective Therapy

open access: yesAdvanced Science, EarlyView.
This study successfully engineered vascularized liver organoids (3HLOs) by co‐culturing human reprogrammed hepatocyte‐like cells (hrHLs) with human umbilical vein endothelial cells (HUVECs) and human umbilical mesenchymal stem cells (HUMSCs). Upon implantation, the 3HLOs established functional vascular anastomosis with the host circulation and ...

Nuclear Factor I‐B Delays Liver Fibrosis by Inhibiting Chemokine Ligand 5 Transcription

open access: yesAdvanced Science, EarlyView.
This study identifies the transcription factor Nuclear Factor I‐B (NFIB) as a key suppressor of liver fibrosis. NFIB expression declines during hepatic stellate cell activation, and its overexpression reduces fibrosis in mice models. The mechanism involves NFIB directly repressing chemokine C─C motif ligand 5 (CCL5), thereby alleviating oxidative ...

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

open access: yesAdvanced Science, EarlyView.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.

Red Blood Cells Internalize Extracellular DNA via Apoptotic Bodies with Clinical Relevance to Cancer Patients

open access: yesAdvanced Science, EarlyView.
Mature red blood cells (RBCs) can capture extracellular DNA, with short fragments homologous to cfDNA. This uptake is mediated by apoptotic bodies, which induce RBC oxidative stress, deformation, and accelerated in vivo clearance. The rbcDNA abundance correlates with tumor burden and therapeutic response, highlighting its potential as a liquid biopsy ...

Transplantation of GABAergic Interneuron Progenitors Restores Cortical Circuit Function in an Alzheimer's Disease Mouse Model

open access: yesAdvanced Science, EarlyView.
Transplantation of medial ganglionic eminence (MGE) interneuron progenitors into APP/PS1 cortices restored the slow oscillation characteristic of Alzheimer's disease. Donor cells survived, migrated, and matured into functional GABAergic interneurons, forming synaptic connections.
