Matrix metalloproteinases (MMPs) are a family of peptidases that possess the ability to break down extracellular matrix macromolecules associated with tissue turnover in various physiological and pathological conditions. Their activity is largely regulated by specific tissue inhibitors of MMPs (...

BackgroundDoxorubicin (DOX) is a highly effective anti-cancer drug with limited clinical use due to its serious cardiotoxicity. Recent studies reported that erythropoietin (EPO) could exert a cardioprotective effect by non-erythropoietic effects. This study was to investigate fibrosis of DOX-ind...

ObjectiveTo investigate effects of Saikosaponin D (SSd) on syndecan-2, matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases-2 (TIMP-2) in livers of rat with hepatocellular carcinoma (HCC).

In this study, the predictive roles of matrix metalloproteinase (MMP)-9 and tissue inhibitor of matrix metalloproteinase (TIMP)-1 and 2 in invasive and noninvasive prolactinomas were examined. Prognostic biomarkers to distinguish between invasive and noninvasive pituitary adenomas are required f...

ObjectiveTo study the effect of Lichong decoction (LD) on expression of matrix metalloproteinase-2 (MMP-2) and metalloproteinase-2 (TIMP-2) in a rat model of uterine leiomyoma (UL).

IntroductionAutosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive cyst formation and variable renal function decline that frequently leads to end-stage renal failure. With the advent of renoprotective treatment, there is renewed interest in noninvasive biomarkers t...

Hevea rubber tree (Hevea brasiliensis) is the only plant species being cultivated for commercial production of rubber in the world. In order to meet ever increasing rubber demand, it is a prerequisite to identify and characterize a key gene involved in rubber biosynthesis and over-expression of ...

Background: Allergy to latex-containing articles is becoming more and more important because it can result in unexpected life-threatening anaphylactic reactions in sensitized individuals.Methods: A protein of 58 kd with an isoelectric point of 8.45 was purified from raw latex and from latex glov...

It is still a challenge to achieve simultaneous improvements in aging resistance, mechanical strength, thermal conductivity and dielectric constant of rubber composites via incorporation of graphene obtained by conventional methods. Herein, an effective and green method was proposed to simultane...

The analysis of rubber-accelerated aging test data provides a scientific basis for the prediction of rubber component storage life, optimal maintenance cycle development, equipment operation status monitoring and health management, and the identification of the acceleration factor is the key ste...

This paper presents the characterization of the mechanical properties, of the ability to crystallize thermally or under strain, and of the Elastically Active Chains (EAC) network of Natural Rubber elastomer, whose EAC average density and length distribution were modified by thermo-oxidative agei...

Rubber-filler interaction is one of the important factors that determine final properties of a composite materials. However, the process of making a homogeneous and stable dispersion of reduced graphene oxide (rGO) or graphene in the natural rubber latex matrix remains a major challenge. In this...

Small rubber particle protein (SRPP) is a major rubber particle-associated protein in latex from rubber tree (Hevea brasiliensis Muell. Arg.), and it implicated in the natural rubber biosynthesis. However, the regulatory mechanism of H. brasiliensis SRPP gene (HbSRPP) is incompletely understood....

A protein named TbREF that is localized on rubber particles of the rubber producing dandelion species Taraxacum brevicorniculatum was expressed in tobacco leaves and in yeast. TbREF fused to fluorescence proteins colocalized on globular, hydrophobic structures, most likely lipid droplets. Furthe...

Rubber elongation factor (REF) is the most abundant protein found on the rubber particles or latex from Hevea brasiliensis (the Para rubber tree) and is considered to play important roles in natural rubber (cis-polyisoprene) biosynthesis. 16 BAC (benzyldimethyl-n-hexadecylammonium chloride)/SDS-...

The common proteins rubber elongation factor (REF) and small rubber particle protein (SRPP) are associated with Hevea brasiliensis (Hb) rubber particles. They are involved in the stability of rubber particles and natural rubber biosynthesis. Recently, we cloned cDNAs encoding REF and SRPP from l...

The region of the maxicircle of Trypanosoma brucei kinetoplast DNA which hybridizes at low stringency with the apocytochrome b gene of Saccharomyces cerevisiae has been identified and cloned. The nucleotide sequence of a 1.7 kb segment of this region is reported. This segment contains a single l...

Cell adhesion molecules (CAMs) implement the process of axon guidance by promoting specific selection and attachment to substrates. We show that, in Drosophila, loss-of-function conditions of either the Neuroglian CAM, the FGF receptor coded by the gene heartless, or the EGF receptor coded by DE...

Engrailed is expressed in subsets of interneurons that do not express Connectin or appreciable Neuroglian, whereas other neurons that are Engrailed negative strongly express these adhesion molecules. Connectin and Neuroglian expression are virtually eliminated in interneurons when engrailed expr...

To further investigate the role of the Drosophila cell adhesion molecules (CAMs), we have developed an in vitro assay that allows us to test the contribution individual CAMs make to promote outgrowth of specific Drosophila neurons. The extension of primary cultured neurons on a substrate of puri...
