PURPOSE To establish a rat flexor tendon laceration and repair model to investigate the molecular mechanisms of flexor tendon healing. METHODS Surgery was performed on rat flexor digitorum longus tendons from both hind feet. Repaired tendons were harvested at 0, 3, 7, 14, 21, 28, 42, 56, and 84 days after surgery. Histologic study (first 84 days) and gene expression study (first 28 days) of s...
Matrix metalloproteinases have a range of biological functions, including the liberation of cytokines and membrane-bound receptors, with roles in promotion of tumor invasion and angiogenesis. Several polymorphisms in MMPs have been implicated in the development of cancer as well as other diseases. Since their frequency distributions in the general North Indian population is not known the presen...
The matrix metalloproteinases (MMP) function as regulators of the dynamic tissue remodeling that occurs in the endometrial lining of the uterus during the normal human menstrual cycle; dysregulation of the MMPs is thought to contribute to the development of both endometriosis and endometrial cancer (1). MMP-1 expression was found to be significantly higher in endometriotic lesions than in surro...
Neutrophil elastase is the most significant predictor of bronchiectasis in early-life cystic fibrosis; however, the causal link between neutrophil elastase and airway damage is not well understood. Matrix metalloproteinases (MMPs) play a crucial role in extracellular matrix modelling and are activated by neutrophil elastase. The aim of this study was to assess if MMP activation positively corre...
BACKGROUND The levonorgestrel-releasing intrauterine system (LNG-IUS) is an effective contraceptive and has many non-contraceptive health benefits. However, it is commonly associated with irregular endometrial bleeding. Metalloproteinases contribute to extracellular matrix (ECM) remodelling and regulate bleeding during the menstrual cycle. Enhanced metalloproteinase expression participates in t...
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a rare lung disease of unknown origin leading rapidly to death. This paper addresses the issue of whether sputum induction is a suitable tool to study respiratory tract inflammation and potential biomarkers in IPF compared to COPD, a fibrosing airway wall disease. METHODS In a cross-sectional analysis, 15 IPF patients, 32 COPD and 30 healthy s...
Background and Objective: liver disease is highly prevalent in type 2 diabetes mellitus (T2DM) and exercise training is effective in preventing and treating diabetes-induced hepatic injury. Therefore, the aim of this study was to assess the effect of chronic swimming exercise on the hepatic matrix metalloproteinase 2 (MMP-2) activity and tumor necrosis factor-α (TNF-α) level of live...
The cyclic growth, differentiation, and cell death of endometrium represents the most dynamic example of steroid-driven tissue turnover in human adults. Key effectors in these processes-matrix metalloproteinases (MMPs) and their specific inhibitors (TIMPs)-are regulated by ovarian steroids and, locally, by cytokines. We used reverse transcription-polymerase chain reaction to evaluate the expres...
BACKGROUND Matrix metalloproteinases (MMPs) and their inhibitors are key-players in extracellular matrix and basement membrane degradation, and are involved in both physiological and malignant processes. The aim of this study was to examine MMP-2, -7 and -9 and TIMP-1 and -2 expression in normal, hyperplastic and malignant endometrium, and their relation to clinical and histological prognostic ...
آندومتریوز یکی از بیماری های تهاجمی اما خوش خیم زنان است که به صورت حضور غدد و استرومای آندومتریال در خارج از حفره ی رحم شکل می گیرد. برای چسبیدن، تهاجم و گسترش قطعات آندومتریال، باید تغییر وضع وسیعی در لایه مزوتلیال صفاقی وجود داشته باشد، که همانند قاعدگی نرمال، این تغییر وضع نیازمند فعال شدن ماتریکس متالوپروتئیناز ها (mmps) است. ماتریکس متالوپروتئیناز ها خانواده ای از اندوپپتیدازهای وابسته به...
