HMGB2–RAD21 Axis Promotes Fibro/Adipogenic Progenitor Proliferation and Regulates Fat Infiltration

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
This study constructed the first developmental atlas of embryonic skeletal muscle fibro/adipogenic progenitors (FAPs) and identified an HMGB2+ FAPs subpopulation that regulates FAP pool size and muscle homeostasis. HMGB2 directly targets the RAD21 promoter, and its knockout significantly reduces FAP numbers, thereby lowering the potential for ...

Senescent Synovial Intimal Fibroblasts Aggravate Osteoarthritis by Regulating Macrophage Polarization and Chondrocyte Phenotype Through ANGPTL4‐α5β1 Axis

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
Senescent synovial intimal fibroblasts (SIF) are identified as key drivers of osteoarthritis. They promote M1 macrophage polarization and cartilage degeneration via the ANGPTL4–α5β1 axis, regulated by transcription factors EGR1 and ATF3. Pharmacological inhibition of this pathway alleviates disease, revealing SIF senescence as a promising therapeutic ...

m1A‐Dependent TRMT6/61A‐ARG2 Axis Drives Protumorigenic Senescence by Remodeling the Tumor Microenvironment

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
Uncovering a new layer of translational control, this study reveals how TRMT6/TRMT61A‐mediated tRNA‐m1A methylation drives pro‐tumorigenic senescence in colorectal cancer. By selectively enhancing ARG2 translation, this epitranscriptomic axis triggers an NF‐κB‐dependent SASP.

Co‐Treatment With rhBMP‐2 and Rapamycin Modulates Osteogenesis–Adipogenesis Balance to Enhance Aged Bone Regeneration

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
This study demonstrates that the imbalance between osteogenic and adipogenic differentiation in senescent BMSCs, leading to excessive adipocyte accumulation, which subsequently impairs bone regeneration in aged mice. To address this pathological dysregulation, a novel energy‐supplying hydrogel system (PBR) has been developed to restore balanced ...

Engineering Immune Cell to Counteract Aging and Aging‐Associated Diseases

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
This review highlights a paradigm shift in which advanced immune cell therapies, initially developed for cancer, are now being harnessed to combat aging. By engineering immune cells to selectively clear senescent cells and remodel pro‐inflammatory tissue microenvironments, these strategies offer a novel and powerful approach to delay age‐related ...

The protective effects of vitamin E and C against oxidative stress induced by sulfasalazine in the testis of male adult rats

open access: yesJournal of Fasa University of Medical Sciences, 2012
Background & Objective: Sulfasalazine (SASP) is a drug used for the treatment of inflammatory bowel diseases. SASP causes testicular damage. The aim of this study was to verify whether or not an additional supply of vitamin E or C or together prevent the

Dual‐Target ROS‐Driven Spatiotemporal Senolysis for Vascular Repair and Immune Microenvironment Reprogramming in the Treatment of Ocular Fundus Neovascularization

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
We developed a senolytic approach using procyanidin C1 (PCC1)‐loaded platform, a clinically established and safe hyaluronic acid‐based scaffold, to selectively eliminate senescent endothelial and microglial cells. This dual‐targeting strategy significantly suppresses pathological neovascularization and promotes vascular repair, presenting a safe and ...

Symbolic Action Motivates Further Collective Action by Increasing Identification With the Common Cause

open access: yesJournal of Community &Applied Social Psychology, Volume 36, Issue 2, March/April 2026.
ABSTRACT Publicly broadcasting one's support for a social cause is often maligned as ‘slacktivism’. We investigate whether such symbolic action by advantaged group members in support of the cause of a disadvantaged group can motivate more concrete collective action when it solidifies a sense of belonging to a common cause.

Study of auxiliary propulsion requirements for large space systems. Volume 1: Executive summary [PDF]

open access: yes
An insight into auxiliary propulsion systems (APS) requirements for large space systems (LSS) launchable by a single shuttle is presented. In an effort to scope the APS requirements for LSS, a set of generic LSSs were defined.
