Mechanical Activation of Piezo1 Drives Osteoarthritis Through Kdm5c‐Mediated Epigenetic Silencing

Advanced Science, EarlyView.
Excessive mechanical stress activates Piezo1, triggering Ca2+‐dependent cytoskeletal forces that deform the nucleus and reduce H3K4me3. Kdm5c demethylates H3K4me3 at Col2a1 and Runx3 promoters. Kdm5c knockout rescues degradation. Repurposed telmisartan directly inhibits Kdm5c, blocking this axis and showing disease‐modifying efficacy in mouse OA models

Identification of active Plasmodium falciparum calpain to establish screening system for Pf-calpain-based drug development

Malaria Journal, 2013
Background With the increasing resistance of malaria parasites to available drugs, there is an urgent demand to develop new anti-malarial drugs. Calpain inhibitor, ALLN, is proposed to inhibit parasite proliferation by suppressing haemoglobin degradation.

Intracellular versus extracellular inhibition of calpain I causes differential effects on pain in a rat model of joint inflammation

Molecular Pain, 2021
Calpain I is a calcium-dependent cysteine protease which has dual effects on tissue inflammation depending on its cellular location. Intracellularly, calpain I has pro-inflammatory properties but becomes anti-inflammatory when exteriorised into the ...

Deconstruction of Human Age‐Related Cataract Capsules Defines Aging

Advanced Science, EarlyView.
We generate a comprehensive atlas of age‐related cataracts (ARC) at a single‐cell resolution, encompassing three disease states—mild cataract group (Mild), severe cortical cataract group (Severe_C), and severe nuclear cataract group (Severe_N). We find that ARC involves seven distinct lens capsule cell types, with notable differences in cellular ...

Spatio-temporal regulation of calpain activity after experimental myocardial infarction in vivo

Biochemistry and Biophysics Reports, 2021
Background: Calpains are calcium activated cysteine proteases that play a pivotal role in the pathophysiology of cardiac remodeling. Methods: Here, we performed left anterior descending coronary artery ligation in rats as a model for ischemic systolic ...

Peripheral Blood DNA Methylation Changes Precede Lymphoma Diagnosis in Primary Sjögren's Disease

Arthritis &Rheumatology, EarlyView.
Objective Primary Sjögren's disease (SjD) is a systemic autoimmune disease associated with an increased risk of lymphoma. The molecular mechanisms underlying lymphomagenesis remain poorly understood, and sensitive biomarkers for early identification of patients at high risk of developing lymphoma are lacking.

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

BMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.
