BACKGROUND: Matrix metalloproteinases (MMPs) have been implicated in the pathogenesis of arterial aneurysms through increased proteolysis of extracellular matrix proteins. Increased proteolysis due to elevated matrix degrading enzyme activity in the arterial wall may act as a susceptibility factor for the development of coronary aneurysms. The aim of this study was to investigate the associatio...

Although TroA (Tromp1) was initially reported to be a Treponema pallidum outer membrane protein with porin-like properties, subsequent studies have suggested that it actually is a periplasmic substrate-binding protein involved in the transport of metals across the treponemal cytoplasmic membrane. Here we conducted additional physicochemical studies to address the divergent viewpoints concerning...

Experimental data for the unfolding of cytochrome c and azurin by guanidinium chloride (GuHCl) are used to construct free-energy diagrams for the folding of the oxidized and reduced proteins. With cytochrome c, the driving force for folding the reduced protein is larger than that for the oxidized form. Both the oxidized and the reduced folded forms of yeast cytochrome c are less stable than the...

The hyp operon encodes accessory proteins that are required for the maturation of the [NiFe] hydrogenase enzymes and, in some organisms, for the production of urease enzymes as well. HypA or a homologous protein is required for nickel insertion into the hydrogenase precursor proteins. In this study, recombinant HypA from Escherichia coli was purified and characterized in vitro. Metal analysis w...

Beans (Phaseolus vulgaris L.) are among the main sources of protein and minerals. The cooking of the grains is imperative, due to reduction of the effect of some toxic and antinutritional substances, as well as increase of protein digestibility. In this study, the effects of cooking on albumins, globulins, prolamins, and glutelins concentration and determination of Fe associated with proteins f...

Multiple myeloma (MM) is incurable cancer in the blood system. Magnolol an effective component against various cancers. This study tried to investigate effect and mechanism of magnolol on MM via regulating miR-129. Human normal plasma cells (nPCs) U266 LP1 were used this study, accompanied by treatment magnolol. The miR-129 inhibitor was transfected into during experiments. Cell viability detec...

Long non?coding RNAs (lncRNAs) are involved in the occurrence and progression of numerous types cancer. The aim present study was to evaluate effect lncRNA maternally expressed gene 3 (MEG3) on migration invasion non?small cell lung cancer (NSCLC) H1299 PC9 cells. Reverse transcription?quantitative (RT?q)PCR analysis showed that MEG3 downregulated NSCLC Additionally, bioinformatics indicated sp...
