An Engineered PfAgo with Wide Catalytic Temperature Range and Substrate Spectrum

open access: yesAdvanced Science, EarlyView.
This work presents a strategy for engineering thermophilic Ago proteins to obtain wide catalytic temperature range and broad substrate spectrum. This strategy is applied to engineer PfAgo and TtdAgo, and the biochemical properties of the engineered PfAgo are systematically characterized. The study further elucidates the structural differences involved.

Collaborative Duality of CircGLIS3(2) RNA and Protein in human Wound Repair

open access: yesAdvanced Science, EarlyView.
CircGLIS3(2), a circRNA transiently upregulated in dermal fibroblasts during acute wound healing, is induced by IL‐1α and TGF‐β. Its RNA activates fibroblasts into matrix‐secreting cells, while its encoded protein enhances proliferation. The RNA stabilizes PCOLCE, and the protein interacts with BTF3, collectively accelerating wound repair. Abstract The

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

open access: yesAdvanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Pyruvate Carboxylase in Macrophages Aggravates Atherosclerosis by Regulating Metabolism Reprogramming to Promote Inflammatory Responses Through the Hypoxia‐Inducible Factor‐1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
This study investigates the role of macrophage pyruvate carboxylase (PC) in atherosclerosis (AS) demonstrating that PC upregulation in macrophages promotes metabolism reprogramming to enhance inflammatory responses via the HIF‐1 signaling pathway.

Semaphorin 3E‐Plexin‐D1 Pathway Downstream of the Luteinizing Hormone Surge Regulates Ovulation, Granulosa Cell Luteinization, and Ovarian Angiogenesis in Mice

open access: yesAdvanced Science, EarlyView.
The Semaphorin 3E (Sema3E)‐Plexin‐D1 pathway mediated by C/EBPα and C/EBPβ downstream of the luteinizing hormone (LH) surge plays important roles in the mouse preovulatory ovary. Timely activation and suppression of this pathway during the preovulatory stage are crucial for ovulation, corpus luteum formation, and proper angiogenesis.

Dual‐Locking the SARS‐CoV‐2 Spike Trimer: An Amphipathic Molecular “Bolt” Stabilizes Conserved Druggable Interfaces for Coronavirus Inhibition

open access: yesAdvanced Science, EarlyView.
A new amphipathic molecule, S416 is discovered, that locks the SARS‐CoV‐2 spike protein in its closed state, blocking viral entry. S416 acts as a molecular bolt, binding six sites: three between adjacent RBDs and three connecting NTDs to RBDs. This dual‐locking mechanism stiffens the spike structure and reduces its flexibility.
