Homoisoflavanone Delays Colorectal Cancer Progression via DNA Damage‐Induced Mitochondrial Apoptosis and Parthanatos‐Like Cell Death

Advanced Science, EarlyView.
Homoisoflavanone (HIF), a bioactive compound isolated from Polygonatum kingianum, selectively suppresses colorectal cancer progression by inducing DNA damage‐mediated mitochondrial apoptosis and parthanatos‐like cell death. HIF triggers mitochondrial dysfunction, including depolarized membrane potential, elevated ROS, and ATP depletion, while impairing

Spatiotemporal dynamics of homologous recombination repair at single collapsed replication forks

Nature Communications, 2018
How factors involved in homologous recombination interact and function is a matter of interest. Here the authors use super-resolution imaging to describe the spatiotemporal dynamics of proteins associated with homologous recombination DNA repair in ...

Lipid Droplet‐Localized Spindle Apparatus Coiled‐Coil Protein 1 Regulates Lipid Droplet Distribution

Advanced Science, EarlyView.
SPDL1‐L, a long isoform of SPDL1, is identified as a bona fide lipid droplet‐associated protein that acts as a dynein adaptor to drive perinuclear clustering of lipid droplets. By linking lipid droplets to the microtubule network, SPDL1‐L extends the function of SPDL1 beyond mitosis and contributes to lipid droplet organization and nuclear remodeling ...

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

Advanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

Contribution of Gli1+ Adventitial Stem Cells to Smooth Muscle Cells in Atherosclerosis and Vascular Injury

Advanced Science, EarlyView.
Gli1+ adventitial stem cells (ASCs) have been thought to generate smooth muscle cells (SMCs) in atherosclerosis. Using a dual‐recombinase lineage tracing to exclude ectopic labeling, Wang et al. found that Gli1+ ASCs do not contribute to SMCs in atherosclerotic plaques.

Cleavage‐Resistant CYLD Protects Against Autoimmune Hepatitis

Advanced Science, EarlyView.
Proteolytic cleavage of the deubiquitinase CYLD emerges as a critical driver of autoimmune hepatitis. TNFα‐induced CYLD loss in macrophages amplifies S100A9‐triggered MAPK activation, leading to excessive chemokine production and hepatic inflammation. Pharmacological inhibition of MEK signaling effectively attenuates experimental disease, highlighting ...

Targeted recombination between homologous chromosomes for precise breeding in tomato

Nature Communications, 2017
Homologous recombination (HR) between parental chromosomes occurs stochastically. Here, we report on targeted recombination between homologous chromosomes upon somatic induction of DNA double-strand breaks (DSBs) via CRISPR-Cas9.

Proteogenomic Characterization Reveals Subtype‐Specific Therapeutic Potential for HER2‐Low Breast Cancer

Advanced Science, EarlyView.
Multiomic profiling of HER2‐low breast cancer identifies three proteomic subtypes with distinct therapeutic strategies: endocrine, antiangiogenic, and anti‐HER2 therapies. Genomic and lactate modification landscapes are detailed, providing insights for precise management.

Interplay between Fanconi anemia and homologous recombination pathways in genome integrity

EMBO Journal, 2016
The Fanconi anemia (FA) pathway plays a central role in the repair of DNA interstrand crosslinks (ICLs) and regulates cellular responses to replication stress. Homologous recombination (HR), the error‐free pathway for double‐strand break (DSB) repair, is
