Integrative Approaches to Treating Cellular Senescence in Kidney Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Cellular senescence in the kidney plays a crucial role in the progression of acute kidney injury and chronic kidney disease. Therapeutic approaches targeting senescent cells, such as small molecule senolytic and senomorphic drugs, display efficacy in preclinical models.

A Renal Clearable Probe for In Vivo Monoamine Oxidase (MAO) Detection

open access: yesAdvanced Science, EarlyView.
A renal‐clearable Cy7‐based fluorogenic probe enables rapid and non‐invasive detection of monoamine oxidase (MAO) activity in vivo. Upon MAO‐mediated activation, the fluorescent product is efficiently excreted in urine, allowing direct quantification of enzyme overexpression.

In vivo fate of bone marrow mesenchymal stem cells implanted into rat pulpotomized molars

open access: yesStem Cell Research, 2019
In our previous work, we established an in vivo coronal pulp regeneration model in which biodegradable hydrogel-made scaffolds carrying rat bone marrow mesenchymal stem cells (BM-MSCs) were implanted in the coronal pulp chamber of pulpotomized rat ...

Inhibiting cGAS‐STING to Preserve Mitochondrial–Nuclear Communication and Stemness in Young Tendon Stem Cells: A Hydrogel Strategy against Age‐Related Tendinopathy

open access: yesAdvanced Science, EarlyView.
A dual‐targeting strategy to rejuvenate aged tendons. A reactive oxygen species (ROS)‐responsive hydrogel co‐delivers a selenium nanozyme (scavenges ROS) and a STING inhibitor to tendon stem cells. This combined action restores mitochondria–nucleus communication, alleviates cellular senescence, and rejuvenates tendon regeneration, offering a novel ...

First Generation Proteolysis Targeting Chimeras (PROTACs) for the Treatment of Progeria

open access: yesAdvanced Science, EarlyView.
We report the first PROTACs designed to degrade progerin, introducing a novel therapeutic approach for progeria. The best compound, UCM‐18142, significantly reduces progerin levels and improves key disease phenotypes in patient‐derived cells and in the LmnaG609G/G609G mouse model, paving the way for new treatment strategies targeting the root cause of ...

Therapeutic Gases in Biomedicine: Updates on Nitric Oxide and Beyond

open access: yesAdvanced Science, EarlyView.
Therapeutic gases, including NO, CO, H2S, H2, CO2, O2, and Xe, play vital roles in cellular signaling and repair. This review highlights the emerging carriers and delivery systems that enable controlled, localized gas release for diagnostic and therapeutic applications.

PRELID1 and VDAC3 Coordinate a Senescence‐Like State in Germinal Center B Cells to Promote IL‐7–Driven Antitumor Immunity in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
Colorectal cancer is characterized by an immunosuppressive microenvironment that limits immunotherapy efficacy. We identify a senescence‐like state in germinal center B cells driven by the PRELID1–VDAC3 axis, which promotes IL‐7 secretion, alleviates CD8+ T‐cell exhaustion, and enhances antitumor immunity. Targeting this pathway improves responsiveness

Study of β-Galactosidase Enzyme Activity Produced by Lactobacilli in Milk and Cheese

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2012
<p>Background and objective Lactose intolerance is a discomfort state that occurs in some people after ingestion of milk and it is due to insufficient amount of beta galactosidase in the human gut to digest lactose.
