Multimodal Investigation of Angiogenesis and Its Prevention by Small Compounds in a Zebrafish Cancer Model

Advanced Science, EarlyView.
A combined optical coherence tomography angiography and fluorescence imaging approach assesses tumor angiogenesis and drug effects in a novel zebrafish cancer model. By analyzing 3D vasculature data, the two imaging methods complement each other to quantify blood flow, vessel structure, and drug efficacy.

Comprehensive Characterization of Bihormonal Cells and Endocrine Cell Lineages in Mammalian Pancreatic Islets

Advanced Science, EarlyView.
This study integrates dual‐reporter genetics, imaging flow cytometry, and single‐cell sequencing to characterize rare bihormonal cells in mouse and human pancreatic islets. Gcg⁺Ins⁺ cells resemble α‐cells rather than transitional states. Cross‐species gene network analysis refines islet cell taxonomy and reveals human‐specific δ‐cell subtypes ...

JA‐Mediated Regulation of Amino Acid Homeostasis Adjusts Metabolic Flux and Enhances Spider Mite Tolerance via the SlJAZ8‐SlWRKY57‐SlAVT6s Module in Tomato

Advanced Science, EarlyView.
This study elucidates a novel SlJAZ8‐SlWRKY57‐SlAVT6A/SlAVT6B module that effectively channels metabolic flux from primary to secondary metabolism, impacting plant growth, development, and resistance. Two novel vacuolar amino acid exporters, SlAVT6A and SlAVT6B, fine‐tunes trichomes, terpenes, and gibberellins, bolstering spider mite resistance.

Integrative Single‐Cell Analysis Reveals Iron Overload‐Induced Senescence and Metabolic Reprogramming in Ovarian Endometriosis‐Associated Infertility

Advanced Science, EarlyView.
Iron overload in ovarian endometriosis (OE) disrupts follicular function and contributes to infertility. This study maps iron‐induced cellular changes using single‐cell and spatial transcriptomics, revealing senescence phenotypes in OE patients and mouse models. Similar patterns are observed in aging ovaries, highlighting iron metabolism as a potential

Gastrula‐Premarked Posterior Enhancer Primes Posterior Tissue Development Through Cross‐Talk with TGF‐β Signaling Pathway

Advanced Science, EarlyView.
A gastrula‐premarked enhancer within the first intron of Cdx2 governs posterior embryonic development via both regulating Cdx2 expression in cis and coordinating TGF‐β signaling in trans to ensure proper posterior body development. Functional rescue in gastruloids reveals a Cdx2‐independent pathway, highlighting p‐Enh‐eRNA as key epigenetic ...
