An Allele of Glutamate Formiminotransferase Triggers 5‐Methyl‐Tetrahydrofolate‐to‐MeFox Conversion and Facilitates Folate Biofortification in Maize

Advanced Science, EarlyView.
This work demonstrates the distinct roles of the glutamate formiminotransferase (GFT) enzyme in plants. The GFT triggers the conversion of 5‐methyl‐tetrahydrofolate to MeFox in plants, a process distinct from its role as a formiminotransferase in mammals.

HERV‐K TM Subunit Elicits CD8+ T Cell Anergy and Tumor Immune Evasion via Targeting CD3 Coreceptor ε in AML and PDAC

Advanced Science, EarlyView.
Novel viral immune checkpoint K‐TM subunit is aberrantly expressed in CD8+ T cells and enriched in sera of cancer patients, inducing CD8+ T cell anergy and eliciting potent tumor immune escape in mouse model. Mechanistically, K‐TM directly targets and induces the phosphorylation of CD3ε receptor.

Snord15b Maintains Stemness of Intestinal Stem Cells via Enhancement of Alternative Splicing of Btrc Short Isoform for Suppression of β‐Catenin Ubiquitination

Advanced Science, EarlyView.
In intestinal stem cells (ISCs), Snord15b associates with Ilf2 to recruit splicing factors for alternative splicing of Btrc mRNA, leading to the generation of short Btrc. This short Btrc fails to form a functional E3 ubiquitin ligase complex for β‐catenin ubiquitination and degradation.

Adaptation of the Pivotal-Differential Genome Pattern for the Induction of Intergenomic Chromosome Recombination in Hybrids of Synthetic Amphidiploids within Triticeae Tribe

Frontiers in Plant Science, 2017
A pivotal-differential evolution pattern is when two allopolyploids share a common genome, which is called pivotal, and differ with respect to the other genome or genomes, called differential.

Modeling Control of Invasive Fire Ants by Gene Drive

Advanced Science, EarlyView.
The fire ant Solenopsis invicta is characterized by exceptional invasive capabilities, rendering conventional control ineffective. Here, we explore the use of homing suppression gene drive in fire ants by developing a spatially explicit model. Overall, these results show that target population suppression requires an extended time scale, but that gene ...

Draper‐ATG3 Interaction Positively Regulates Autophagy to Mediate Silk Gland Degradation in Bombyx mori

Advanced Science, EarlyView.
Draper is evolutionarily conserved across most insect species. Loss of Draper inhibits autophagy activation, delaying middle silk gland degradation in the silkworm during metamorphosis. Draper interacts with autophagy ‐ related protein 3 (ATG3) to orchestrate autophagosome formation—a process essential for silk gland degradation during the larval‐pupal

C14ORF39/SIX6OS1 is a constituent of the synaptonemal complex and is essential for mouse fertility

Nature Communications, 2016
The synaptonemal complex is a meiosis-specific proteinaceous structure that supports homologous chromosome pairs during meiosis. Here, the authors show that SIX6OS1 (of previously unknown function) is part of the synaptonemal complex central element and ...

Topoisomerase II- and condensin-dependent breakage of MEC1ATR-sensitive fragile sites occurs independently of spindle tension, anaphase, or cytokinesis.

PLoS Genetics, 2012
Fragile sites are loci of recurrent chromosome breakage in the genome. They are found in organisms ranging from bacteria to humans and are implicated in genome instability, evolution, and cancer.

Decoding Dental Stem Cell Aging: Mechanisms, Therapeutic Strategies, and Beyond

Advanced Science, EarlyView.
Dental stem cell (DSC) aging involves genomic instability, mitochondrial dysfunction, telomere attrition, and epigenetic alterations, leading to impaired proliferation, reduced differentiation potential, and pro‐inflammatory secretory activity. These processes drive cellular senescence and compromise regenerative and immunomodulatory functions, thereby

Meiotic chromosome movement: what’s lamin got to do with it?

Nucleus, 2019
Active meiotic chromosome movements are a universally conserved feature. They occur at the early stages of prophase of the first meiotic division and support the chromosome pairing process by (1) efficiently installing the synaptonemal complex between ...
