IL1R2 Marks and Sorts a Spermatogonial Stem Cell Population Critical for Restoring Spermatogenesis Upon Interruption in Mammals

open access: yesAdvanced Science, EarlyView.
Spermatogonial stem cells (SSCs) provide critical support to spermatogenesis. Here, the author established Il1r2 as a sorting marker for SSCs, with which further insights into the SSC heterogeneity and dynamic features can be obtained. They also confirmed findings in both mouse and human, thus validating IL1R2 as the surface marker for isolating and ...

Wedelolactone, a Novel TLR2 Agonist, Promotes Neutrophil Differentiation and Ameliorates Neutropenia: A Multi‐Omics Approach to Unravel the Mechanism

open access: yesAdvanced Science, EarlyView.
Wedelolactone (WED), a natural TLR2 agonist, promotes neutrophil differentiation and enhances bactericidal function, offering a potential therapeutic strategy for neutropenia. Using a multi‐omics approach, this study reveals that WED activates the TLR2/MEK/ERK pathway, upregulating key transcription factors (PU.1, CEBPβ) to drive neutrophil development.

The Decline in German Output Volatility: A Bayesian Analysis [PDF]

open access: yes
Empirical evidence suggests a sharp volatility decline of the growth in U.S. gross domestic product (GDP) in the mid-1980s. Using Bayesian methods, we analyze whether a volatility reduction can also be detected for the German GDP.

CHB‐Induced Immune Zonation Chaos Elicited LXRα‐mediated Lipid Metabolism Disorders in Kupffer Cells to Induce Cancer Stem Cell Formation

open access: yesAdvanced Science, EarlyView.
By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...

Does Eco-labeling of Services Matter? Evidence from Higher Education [PDF]

open access: yes, 2016
Eco-labeling of services has become increasingly common, yet little empirical evidence exists concerning its effectiveness. We address this gap in the literature by analyzing a highly visible eco-label, the American College and University Presidents ...

The Disordered Region of ASXL1 Acts as an Auto‐Regulator Through Condensation

open access: yesAdvanced Science, EarlyView.
ASXL1's long IDR encodes an electrostatic “basic platform + acidic brake” that autoregulates condensation. Truncation at a clinical hotspot lifts this brake, forming condensates that retarget BRD2, remodel local chromatin accessibility, and impair neutrophil maturation.

A Self‐Organized Liquid Reaction Container for Cellular Memory

open access: yesAdvanced Science, EarlyView.
How cells restore epigenetic information lost during replication is not known. This work proposes a mechanism based on the formation of biomolecular condensates. These condensates are induced by the chromosome itself and serve as reaction vessels for reconstructing missing epigenetic markers.
