Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

open access: yesAdvanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

X-chromosome inactivation mosaicism in the three germ layers and the germ line of the mouse embryo [PDF]

open access: yes, 1982
Electrophoretic variant forms of the X-linked enzyme phosphoglycerate kinase (PGK-1, E.C.2, 7, 2, 3) have been used to examine X-chromosome mosaicism in tissues from 121/2-day post coitum heterozygous female mouse embryos.

Nurr1 Orchestrates Claustrum Development and Functionality

open access: yesAdvanced Science, EarlyView.
Nurr1 (Nr4a2) is the master transcription factor to control claustrum morphogenesis and cell fate decision postmitotically by inhibiting intracellular G‐protein signaling. Nurr1 deficiency alters the transcriptomic profiles of subcortical claustral neurons into neocortical insular neurons, resulting in defected claustrum development, impaired axonal ...

Stochastic Nanoscale Biophysical Cues as a Basis for the Induction of Glioblastoma‐Like Transcriptional Programs in Astrocytes

open access: yesAdvanced Science, EarlyView.
Stochastic nanoscale physical cues induce glioblastoma (GBM)‐associated transcriptional traits in naïve astrocytes leading to spontaneous formation of spheroids. Cells within spheroids express activated‐MMP2 and a differential gene expression pattern involving P53 and NOTCH3, providing evidence for a role for changes in brain topography, as observed in

Primitive erythropoiesis in the mammalian embryo

open access: yesThe International Journal of Developmental Biology, 2010
Erythropoiesis in adult mammals is characterized by the progressive maturation of hematopoietic stem cells to lineage-specific progenitors, to morphologically identifiable precursors which enucleate to form mature erythrocytes. In contrast, primitive erythropoiesis is characterized by the appearance within the yolk sac of a transient, lineage ...

A Cold Stress‐Activated Endocrine Sentinel Chemical Hormone Promotes Insect Survival via Mitochondrial Adaptations Through the Adipokinetic Hormone Receptor

open access: yesAdvanced Science, EarlyView.
Seasonal cold adaptation is vital for insect survival, yet the molecular mechanisms linking diapause to mitochondrial resilience remain largely unresolved. We identify ascaroside C9 (asc‐C9) as a key endocrine signal that enhances diapause survival during cold stress by activating the AKHR–PGC1α–UCP4 axis, thereby driving cold‐induced lipolysis and ...

Comprehensive Profiling of N6‐methyladnosine (m6A) Readouts Reveals Novel m6A Readers That Regulate Human Embryonic Stem Cell Differentiation

open access: yesAdvanced Science, EarlyView.
This research deciphers the m6A transcriptome by profiling its sites and functional readout effects: from mRNA stability, translation to alternative splicing, across five different cell types. Machine learning model identifies novel m6A‐binding proteins DDX6 and FXR2 and novel m6A reader proteins FUBP3 and L1TD1.

Role of the Mitochondrial Genome During Early Development in Mice [PDF]

open access: yes, 1973
The role of the mitochondrial genome in early development and differentiation was studied in mouse embryos cultured in vitro from the two to four cell stage to the blastocyst (about 100 cells).

Genomics Insights Into High‐Latitude Adaptation of Tibetan Macaques

open access: yesAdvanced Science, EarlyView.
Tibetan macaques exhibit unique adaptations to cold, high‐latitude environments, including shortened tails and enhanced fat storage. Genomic analyses reveal a species‐specific TBX6 mutation linked to tail reduction and selection on lipid metabolism genes.
