Restoration of SIRT3 Expression in Aged Mice Alleviates UUO‐Induced Renal Fibrosis by Reducing GSK‐3β Hyperacetylation

Advanced Science, EarlyView.
SIRT3 expression is significantly downregulated in the aged kidney, rendering the kidney more vulnerable to fibrotic changes in obstructive nephropathy. By promoting GSK‐3β deacetylation, SIRT3 indirectly inhibits Wnt/β‐catenin signaling, thereby suppressing renal fibrosis.

An Apple Susceptibility‐Related LRR Receptor‐Like Kinase MdRLKT21 Activates Plant Immunity by Hijacking a Trans‐Kingdom Fungal microRNA‐Like RNA

Advanced Science, EarlyView.
The apple susceptibility‐related LRR‐RLK MdRLKT21 competitively binds to fungal sRNA effectors and subsequently activates defenses by salvaging the expression of MdRLKT1 and MdRLKT2 and thereby releasing the resistance protein MdRFP1. These findings provide new insights into the molecular mechanism by which plants counteract pathogen‐secreted sRNA ...

Cutaneous cytomegalovirus infection in a child with hyper IgE and specific defects in antibody response to protein vaccines

Brazilian Journal of Infectious Diseases
Cytomegalovirus (CMV) infection is a common opportunistic systemic infection in immunocompromised patients, but skin involvement is rare. Herein, we report a 10 year-old girl from consanguineous parents who was referred to our center because of ...

Irisin Attenuates Pulmonary Vascular Remodeling in Pulmonary Arterial Hypertension via Ubiquitin‐Mediated Regulation of ENO1

Advanced Science, EarlyView.
Irisin is a crucial plasma biomarker and promising therapeutic target that reflects disease severity, pulmonary vascular remodeling status and clinical outcome in patients with pulmonary arterial hypertension (PAH). As a novel protective factor, irisin is downregulated in PAH. By ubiquitination, irisin promotes Enolase 1 degradation and suppresses cell

MYC/TET3‐Regulated TMEM65 Activates OXPHOS‐SERPINB3 Pathway to Promote Progression and Cisplatin Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Triple‐negative breast cancer (TNBC) remains a major challenge in breast cancer management as it lacks effective therapeutic targets. This study uncovers that MYC/TET3‐regulated mitochondrial inner‐membrane protein TMEM65 promotes TNBC progression and cisplatin resistance by activating the OXPHOS‐SERPINB3 pathway and reveals TMEM65 as a potential ...

Intestinal Epithelial‐Derived USP13 Alleviates Colonic Inflammation by Suppressing GRP78‐mediated Endoplasmic Reticulum Stress

Advanced Science, EarlyView.
USP13 deficiency in intestinal epithelial cells aggravates DSS‐induced colitis by enhancing ER stress and apoptosis. USP13 interacts with GRP78 and reduces its K63‐linked ubiquitination to alleviate epithelial injury. Restoring USP13 expression or targeting the USP13‐GRP78 axis may represent a promising strategy for treating inflammatory bowel disease ...

Osteoblast‐CD4+ CTL Crosstalk Mediated by SIRT1/DAAM2 Axis Prevents Age‐Related Bone Loss

Advanced Science, EarlyView.
In the osteoblastic niche, SIRT1 activates and recruits CD4+ CTLs by increasing DAAM2 expression via EZH2 deacetylation and boosting the secretion of key chemokines, such as CCL3, CCL5, and CXCL10. Then, CD4+ CTL directly eliminates senescent osteoblasts in an MHC‐II‐dependent way, thereby slowing down the process of bone ageing and effectively ...
