TIMP3 attenuates cerebral ischemia/reperfusion-induced apoptosis and oxidative stress in neurocytes by regulating the AKT pathway.

Experimental and therapeutic medicine

Meng L, Zhang Y, Li D, Shang X, Hao X, Chen X, Gao F.
PMID: 34335915
Exp Ther Med. 2021 Sep;22(3):973. doi: 10.3892/etm.2021.10405. Epub 2021 Jul 08.

Ischemic stroke seriously threatens human health and creates a large social burden. The present study investigated whether tissue inhibitor of metalloproteinases-3 (TIMP3) prevented cerebral ischemia/reperfusion (I/R), with the aim to explore the underlying mechanism. A transient middle cerebral artery...

Modulation of Cardiac Fibrosis in and Beyond Cells.

The extracellular matrix (ECM) plays important roles in maintaining physiological structure and functions of various tissues and organs. Cardiac fibrosis is the excess deposition of ECM, including both fibrillar (collagens I and III) and non-fibrillar proteins. Characteristics of fibrosis...

CKAP4 participates in tryptase-induced phenotypic conversion in atrial fibroblasts through PAR2/p38/JNK pathway.

American journal of translational research

PMID: 34017388
Am J Transl Res. 2021 Apr 15;13(4):2270-2282. eCollection 2021.

Our previous study found that tryptase activated atrial fibroblasts, increased collagen synthesis in atrial fibroblasts through protease activated receptor-2 (PAR2) receptors. Recent studies showed that cytoskeleton-associated protein 4 (CKAP4) played an important role in ventricular fibroblast activation. The present...

Effects of coenzyme Q10 supplementation on inflammation, angiogenesis, and oxidative stress in breast cancer patients: a systematic review and meta-analysis of randomized controlled- trials.

BACKGROUND/OBJECTIVE: Systemic inflammation and oxidative stress (OS) are associated with breast cancer. CoQ10 as an adjuvant treatment with conventional anti-cancer chemotherapy has been demonstrated to help in the inflammatory process and OS. This systematic review and meta-analysis of randomized...

Relationships between Circulating Matrix Metalloproteinases, Tissue Inhibitor TIMP-2, and Renal Function in Patients with Myocarditis.

Kidney Blood Press Res. 2021 Nov 19;1-9. doi: 10.1159/000519594. Epub 2021 Nov 19.

INTRODUCTION: Under physiological conditions, the myocardial extracellular matrix (ECM) is maintained by matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). However, changes in the balance between MMPs and TIMPs can lead to pathological remodeling of the ECM, which...

A Porcine Model of Heart Failure With Preserved Ejection Fraction Induced by Chronic Pressure Overload Characterized by Cardiac Fibrosis and Remodeling.

Heart failure is induced by multiple pathological mechanisms, and current therapies are ineffective against heart failure with preserved ejection fraction (HFpEF). As there are limited animal models of HFpEF, its underlying mechanisms have not yet been elucidated. Here, we...

Cholestasis caused by slowing or blockage of bile flow is a serious liver disease that can lead to liver fibrosis and cirrhosis. The link between transforming growth factor beta 1 (TGFβ1), Smad family member 3 (Smad3), and microRNA 21...

EGFR-mediated epidermal stem cell motility drives skin regeneration through COL17A1 proteolysis.
