Long‐Term Active Rather than Passive Restoration Promotes Soil Organic Carbon Accumulation by Alleviating Microbial Nitrogen Limitation in an Extremely Degraded Alpine Grassland

open access: yesAdvanced Science, EarlyView.
Active restoration increases soil organic carbon stocks by reducing microbial nitrogen limitation. Nitrogen availability promotes particulate to mineral‐associated organic carbon conversion by reducing microbial carbon use efficiency. Passive restoration has no effect on soil organic carbon stocks.

ACSL5 Regulates Glucose Metabolism and Chemotherapy Sensitivity in Colorectal Cancer Cells under Glutamine Deficiency

open access: yesAdvanced Science, EarlyView.
Glutamine deprivation triggers ACSL5 upregulation in tumor cells, sustaining their viability via dual metabolic rewiring programs. ACSL5 enhances glycolysis by relieving p53's inhibition of PGAM1 while also sustaining mitochondrial respiration and TCA cycle flux through promoting IDH2 dimerization.

Lipid‐Driven OLR1/FOXM1/FGF19 Axis Orchestrates Crosstalk in an Epithelial‐Fibroblast Positive Feedback Promoting Progesterone Resistance in Endometrial Cancer

open access: yesAdvanced Science, EarlyView.
It is revealed that a metabolic–stromal loop driven by oxLDL–OLR1–FOXM1–FGF19 signaling promotes progesterone resistance in endometrial cancer. OxLDL activates epithelial–fibroblast crosstalk, enhancing proliferation and hormonal insensitivity. Disruption of this circuit, especially with resveratrol, restores MPA sensitivity, highlighting a potential ...

Ex Vivo Spatiotemporal Characterization of Spermatogenesis in Mouse Testicular Organoids

open access: yesAdvanced Science, EarlyView.
To date, in vitro spermatogenesis remains a challenge in reproductive medicine. In this study, Sun et al. developed a promising in vitro strategy to generate testicular organoids that enable germ cells from newborn mice to enter meiosis, complete chromosome recombination and synapsis, and develop into haploid spermatids.

Nap1L4a Cooperates with Scl/Klf1 to Recruit H2A.Z in Mediating Interactions Among Cis‐Regulatory Elements and Transcription Required for Primitive Erythropoiesis in Zebrafish

open access: yesAdvanced Science, EarlyView.
Nap1l4a is required in erythropoiesis and hypoxia responses via physical interaction with Klf1 and Scl to recruit the histone variant H2A.Z. This facilitates its associated cis‐regulatory element (CRE) remodeling and the consequent chromatin assembly, and activates the transcription of erythroid lineage‐specific genes.

The Evolutionarily Conserved TPM1 Super‐Enhancer Drives Skeletal Muscle Regeneration via Mechanotransduction Signaling

open access: yesAdvanced Science, EarlyView.
By integrating biomechanical and epigenetic cues, the evolutionarily conserved TPM1 super‐enhancer drives myogenesis via TEAD4‐mediated chromatin looping. This mechanism produces species‐specific outputs (linear TPM1 mRNA in mice and CircTPM1 in bovine) that activate PI3K/AKT mechanotransduction and the MYH10/MYL3 axis to execute cytoskeletal ...

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 ...
