Maternal Preconception Antibiotic Exposure Disrupts Microbial Succession: A Transgenerational Risk for Offspring Gut Mucosal Immaturity and Colitis Susceptibility

open access: yesAdvanced Science, EarlyView.
This study reveals that maternal antibiotic exposure prior to conception disrupts intergenerational gut microbial succession. By enhancing maternal‐offspring microbial transmission, altering microbial developmental trajectories and increasing selective pressures during community assembly, these disturbances lead to persistent gut mucosal immaturity and

Hypofractionated Radiotherapy Induces ISG15+MHC‐I+ Neutrophils to Augment Anti‐Tumor Immunity and Prime Immune Checkpoint Blockade Responses in Rectal Cancer

open access: yesAdvanced Science, EarlyView.
ABSTRACT Our previous clinical trials had demonstrated that neoadjuvant hypofractionated radiotherapy (HFRT) combined with immunotherapy yields promising clinical outcomes in locally advanced rectal cancer (LARC). However, this combined modality benefits only a subset of patients, highlighting the need to uncover the mechanisms underlying how ...

DMAP1 Deficiency Suppresses Lung Cancer Progression by Destabilizing Replication Fork and Activating IFN Signaling‐Mediated Anti‐tumor Immunity

open access: yesAdvanced Science, EarlyView.
Lung cancer remains the leading cause of cancer‐related death. We investigated the role of the epigenetic regulator DMAP1 in NSCLC and found that its loss induces replication stress and DNA damage. This in turn activates type I IFN signaling via the cGAS–STING pathway and transcriptional ISG de‐repression, enhancing anti‐tumor immune responses ...

Organ‐Specific and Conserved Regulatory Logic Orchestrates Gene Expression in the Embryonic Mesothelium

open access: yesAdvanced Science, EarlyView.
Integrated multi‐omic profiling maps the gene‐regulatory landscape of the coelomic mesothelium across heart, lung, and pancreas. A cardiac‐restricted regulatory program is uncovered in which TBX20 activates heart mesothelial (epicardial) cis‐regulatory elements, while MAF emerges as a conserved regulator of mesothelial identity.

Adipocyte‐Derived Exosomal miR‐5099 Mitigates M1 Macrophage Polarization and Adipose Inflammation via c‐Met/NF‐κB Axis to Improve Metabolic Health

open access: yesAdvanced Science, EarlyView.
Celastrol upregulates adipocyte‐derived exosomal miR‐5099, suppressing the macrophage c‐Met/NF‐κB axis to mitigate pro‐inflammatory M1 polarization and adipose inflammation. These miR‐5099‐enriched exosomes also act as endocrine signals targeting the liver, muscle, and adipocytes to significantly enhance systemic insulin sensitivity.

NK Cell Activation by Platinum Boosts Immunotherapy in HR+/HER2− Breast Cancer

open access: yesAdvanced Science, EarlyView.
Multi‐omics and single‐cell analyses identify activated NK cells as key mediators of anti‐PD‐(L)1 response in HR+/HER2− breast cancer. Platinum chemotherapy enhances NK cell cytotoxicity through NF‐κB–associated signaling, synergizing with immunotherapy and providing a rationale for combination treatment.

DNA Barcoding as a Plant Identification Method

open access: yesApplied Sciences
In the last two decades, plant taxonomy has bloomed, following the development of a novel technique, namely, DNA barcoding. DNA barcodes are standardized sequences, ideally unique, coding or non-coding, either from the genome of the organism or from its ...

Reduced Maintenance DNA Methylation Thresholds Enable Sensitive Reporter Assays for UHRF1 and DNMT1 Inhibition

open access: yesAdvanced Science, EarlyView.
The authors engineer colorectal cancer cells with reduced redundancy of UHRF1 and DNMT1, key DNA methylation maintenance factors, lowering the maintenance threshold and sensitizing cells to inhibition. They develop reporter assays driven by endogenous tumor‐suppressor gene promoters with enhanced sensitivity and dynamic range to demethylating drugs ...

Proton FLASH Exposure Preserves Gut Commensal Microbiomes and Spares Intestinal Stem Cells

open access: yesAdvanced Science, EarlyView.
This study highlights the role of Proton FLASH abdominal irradiation in sparing of intestinal stem cells and preservation of key gut microbial population resulting minimization of radiation toxicity in intestinal epithelium in mice. Our findings support the potential of Proton FLASH to improve the therapeutic ratio for abdominal radiation exposure ...

DNA Origami Barcodes for Immunostaining

open access: yesACS Applied Materials & Interfaces
In histology, immunostaining of biological samples is a gold standard for studying cellular processes, such as the expression of cell surface markers or the cellular uptake of proteins and drug molecules. Immuno-gold labeling is a commonly used technique to achieve nanometer spatial resolution, but simultaneous visualization of multiple antigens in ...
