Abstract Background Patellar instability (PI) often increases the possibility of lateral patellar dislocation and early osteoarthritis. The molecular mechanism articular cartilage degeneration during patellofemoral osteoarthritis (PFOA) still requires further investigation. However, it is known that NF-κB signaling pathway plays an important role in degeneration. aim this study was to investiga...

A promising method for transforming lignin derivatives into high-value chemicals and biofuels is hydrodeoxygenation (HDO), which anticipated to be a viable feasible protocol the biorefinery. Nonetheless, requirements of high temperature H2 pressure are two main hurdles in HDO process. Herein, we developed highly active Pd-decorated Bi2MoO6 nanoflakes complete selective vanillin (a typical ligni...

Inhaled corticosteroids (ICS) are the key component of asthma treatment. However, it is unclear whether they could control the activity and level of matrix metalloproteinase (MMP)-9, which is an important factor in asthma-associated inflammation and airway remodeling. Therefore, the aim of this proof of concept study was to analyze the influence of increased doses of ICS on MMP-9 in exhaled bre...

PURPOSE To evaluate the level of matrix metalloproteinase (MMP)-2 and MMP-9 activities in patients with steroid induced posterior subcapsular cataract (PSC). METHODS This prospective, observational study comprised of 156 patients having either steroid induced PSC (n=50) or non-steroidal PSC (n=106) were performed to evaluate the level of MMP-2 and MMP-9 activities in the lens epithelial cells...

Introduction: Glioblastoma is an aggressive malignancy of human brain with poorly understood pathogenesis. Voltage-gated potassium (Kv) channels and Matrix metalloproteinases (MMPs) are highly expressed in malignant tumors and involved in the progression and metastasis of glioblastoma. The purpose of this study was to determine whether a voltage-dependent potassium channel blocker could modulat...

BACKGROUND Broad inhibition of matrix metalloproteinases (MMPs) attenuates left ventricular remodeling after myocardial infarction (MI). However, it is not clear if selective MMP inhibition strategies will be effective or if MMP inhibition will impair angiogenesis after MI. METHODS AND RESULTS We used a selective MMP inhibitor (MMPi) that does not inhibit MMP-1 in rabbits, which, like humans ...

Tumor cells use membrane type 1 matrix metalloproteinase (MT1-MMP) for invasion and metastasis. However, the signaling mechanisms that underlie MT1-MMP regulation in cancer have remained unclear. Using a systematic gain-of-function kinome screen for MT1-MMP activity, we have here identified kinases that significantly enhance MT1-MMP activity in tumor cells. In particular, we discovered an MT1-M...

Objective Matrix Metalloproteinase (MMPs) play important roles in the structural and functional properties of reproductive organs. The aim of this study is to determine the prevalence of C-1562T Matrix Metalloproteinase-9 (rs3918242) gene polymorphism in fertile and infertile men. In addition, we aimed to determine the association between C-1562T MMP-9 and G-1575A MMP-2 gene polymorphisms. Mate...

BACKGROUND Cutaneous wound healing results in scar formation. Matrix metalloproteinases (MMP) transform extracellular matrix proteins and modulate inflammation and cell signaling, thus determining scar outcome. To provide rapid wound closure and reduced scarring, dermal scaffolds were introduced. Little is known about the influence of these materials on MMPs levels. MATERIAL AND METHODS In th...

The main pathological characteristic of osteoarthritis (OA) is cartilage damage. We explored cartilage oligomeric matrix protein (COMP) and matrix metalloproteinase-3 (MMP-3) changes during articular cartilage injury and repair. Rabbits were randomly divided into the following: a blank control group; groups M1, M2, and M3, in which breaking was performed for 2, 4, and 6 weeks, respectively; and...
