Ionizing Radiations and the Mammalian Embryo [PDF]

open access: yesActa Radiologica: Therapy, Physics, Biology, 1963
It was found that the mammalian embryo shows varying reactions to ionizing radiations such that it is always more radiosensitive than is the adult into which it develops, at some stages 100 times as sensitive. After neurogenesis is completed, congenital anomalies of that system are rarely producod, but exencephaly (hrain hernia) has been caused by ...

Compressed Cells Facilitate Adhesion Through Glycocalyx

open access: yesAdvanced Science, EarlyView.
This study quantifies how cell compression and confinement triggers cell adhesion. Under low compression, integrins dominate cell adhesion to extracellular matrix (ECM) proteins, whereas the glycocalyx contributes weak unspecific adhesion. With increasing compression, the glycocalyx increases its unspecific adhesion to ECM and non‐ECM proteins and can ...

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

open access: yesAdvanced 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.

Optogenetic‐Controlled iPSC‐Based Vaccines for Prophylactic and Therapeutic Tumor Suppression in Mice

open access: yesAdvanced Science, EarlyView.
This study develops an a red/far‐red light‐controlled iPSC‐based vaccines (RIVA) based on the chimeric photosensory protein FnBphP and its interaction partner LDB3 for cancer immunotherapy. The RIVA preserves the multiple intrinsic tumor antigens of iPSCs and enables optogenetic control of the expression of the immune adjuvant type I interferon β under

Patterns and Processes of Genomic Evolution Inferred From the Ten Smallest Vertebrate Genomes

open access: yesAdvanced Science, EarlyView.
By integrating phylogenetic relationships derived from nuclear DNA with population genetic analyses across ten pufferfish species, the genetic differentiation mechanisms underpinning the radiative speciation of the most compact vertebrate genomes has elucidated.

Tracing and Capturing the Epiblast Pluripotency of Sheep Preimplantation Embryos

open access: yesAdvanced Science, EarlyView.
This study performs a comprehensive single‐cell transcriptome analysis of sheep embryos from embryonic (E) day 1 to E14 to elucidate the mechanism of early lineage specification and the pluripotency changes (naïve, formative, and primed) of epiblast.

Novel Antimicrobial Protein Fibroblast Growth Factor 8 Accelerates Skin Wound Healing via Directly Inhibiting Bacteria and Activating Glycolysis

open access: yesAdvanced Science, EarlyView.
Wound infections induce gcFGF8a expression, which subsequently executes direct antimicrobial activity to suppress local infection while simultaneously activating the FGFR4‐mediated ERK/AKT‐mTOR signaling cascade, thereby upregulating HIF1α and enhancing glycolysis. These coordinated actions synergistically promote tissue repair by eliminating pathogens

The Chicken Embryo: An Old but Promising Model for In Vivo Preclinical Research

open access: yesBiomedicines
The chicken embryo has emerged as a valuable model for preclinical studies due to its unique combination of accessibility, affordability, and relevance to human biology.

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

open access: yesAdvanced 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 ...
