DEL‐1 is an Endogenous Senolytic Protein that Inhibits Senescence‐Associated Bone Loss

open access: yesAdvanced Science, EarlyView.
Senescent bone marrow stromal cells accumulate in the aging bone microenvironment, promoting bone degeneration. DEL‐1, an endogenous secreted protein, acts as a natural senolytic that selectively eliminates these cells. By engaging a β3 integrin/CD73/adenosine/p38 MAPK/BCL‐2 pathway, DEL‐1 counters aging‐related bone loss, revealing promising ...

5‐Hydroxymethylcytosine Dynamics Reveals Coordinated Reprogramming of Parental Genomes and X Chromosome Dosage Balance in Mouse SCNT Embryos

open access: yesAdvanced Science, EarlyView.
Genome‐wide, high‐resolution profiling of hydroxymethylation in mouse SCNT embryos reveals a transient, allele‐symmetric 5hmC reprogramming pattern distinct from natural embryos, with X‐chromosomes and imprinting control regions resistant to proper remodeling.

GSK3β‐Regulated Lipolysis is Required for Histone Acetylation and Decidualization in Early Pregnancy

open access: yesAdvanced Science, EarlyView.
Uterine Gsk3b knockout impairs decidual cell terminal differentiation by causing lipid droplet accumulation. GSK3β phosphorylates RNF213 to promote its lysosomal degradation, thereby enhancing lipolysis. The released fatty acids undergo β‐oxidation to generate acetyl‐CoA, which modulates histone acetylation and regulates decidual cell terminal ...

Interactome comparison of human embryonic stem cell lines with the inner cell mass and trophectoderm [PDF]

open access: yes, 2018
Networks of interacting co-regulated genes distinguish the inner cell mass (ICM) from the differentiated trophectoderm (TE) in the preimplantation blastocyst, in a species specific manner.

Autocrine Netrin‐1 Signaling in Hepatic Stellate Cells Drives Liver Fibrosis and Diet‐Induced Metabolic Dysfunction‐Associated Steatohepatitis in Mice

open access: yesAdvanced Science, EarlyView.
Netrin‐1 expression is upregulated in hepatic stellate cells (HSCs) during metabolic dysfunction–associated steatohepatitis and injury‐mediated liver fibrosis. Secreted Netrin‐1 establishes an autocrine positive feedback loop by binding to UNC5B receptors on HSCs.

Pregnancy and perinatal outcomes after day 5 versus day 6 blastocyst-stage embryo transfer: A systematic review and meta-analysis. [PDF]

open access: yesActa Obstet Gynecol Scand
We conducted a meta‐analysis to compare the pregnancy and perinatal outcomes after day 5 versus day 6 single frozen‐thawed blastocyst transfer, aims to identify more appropriate strategies for transplantation. ART practitioners should give priority to transfer D5 rather than D6 blastocysts in single vitrified‐warmed cycle in clinical practice. Abstract

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).

PFOS Disrupts Oocyte Maturation and Early Embryonic Development via Ovarian FOXK1 O‐GlcNAcylation in Mice

open access: yesAdvanced Science, EarlyView.
Perfluorooctane sulfonate (PFOS) exposure disrupts oocyte maturation and early embryonic development. This study elucidates the mechanism by which enhanced O‐GlcNAcylation of FOXK1 underlies the PFOS‐induced reduction of progesterone levels in granulosa cells and the disturbance of follicular microenvironment.
