A Study on the Cell Layer Patterns of a Citrus Periclinal Chimera Reveals β‐Cryptoxanthin Regulation in Citrus Fruits

Advanced Science, EarlyView.
Researchers have identified a citrus chimera with distinctive tissue origins and carotenoid profiles. It is discovered that fruit tissues develop from all three cell layers but in different proportions. A key transcription factor, MYB107, regulates β‐cryptoxanthin production by directly activating carotenoid biosynthesis genes, explaining why some ...

Arabidopsis TRB Proteins Form Two Closely Related Complexes to Mediate H3K4me3 Demethylation and Transcriptional Repression

Advanced Science, EarlyView.
This study reveals that Arabidopsis telomere repeat binding proteins (TRBs) form two closely related complexes. These complexes mediate H3K4me3 demethylation and transcriptional repression through a positive feedback loop and cooperate with PEAT and PRC2 complexes to regulate multiple histone modifications and gene expression across the genome ...

Microglial Deletion of Hrh4 Alleviates Alzheimer's Disease Pathologies by Enhancing Microglial Phagocytosis of Amyloid‐β and Tau

Advanced Science, EarlyView.
Histamine H4 receptor (H4R) antagonist VUF6002 mimics low‐dose X‐ray irradiation in aged Alzheimer's disease (AD) mice, enhancing microglial clearance of amyloid‐beta/hyperphosphorylated tau aggregates and restoring cognition. Microglial H4R deletion activates cAMP/TGF‐β1/Smad3 pathway, enhancing phagocytosis, while TGF‐β receptor 1 deletion abolishes ...

Gut Microbial Genetic Variation Prolongs Host Healthy Longevity and Remodels Metabolome and Proteome in Drosophila Melanogaster

Advanced Science, EarlyView.
This study reveals that specific genetic variations in gut‐residing Saccharomyces cerevisiae significantly extend healthspan and lifespan in Drosophila melanogaster. These mutants rejuvenate aged intestinal metabolism, upregulate mitochondrial proteins, and enhance energy pathways.
