TM9 proteins constitute a well defined family, characterized by the presence of a large variable extracellular domain and nine putative transmembrane domains. This family is highly conserved throughout evolution and comprises three members in Dictyostelium discoideum and Saccharomyces cerevisiae and four in humans and mice. In Dictyostelium, previous analysis demonstrated that TM9 proteins are ...

Ferulic acid (FA), a naturally occurring polyphenol abundant in vegetables and rice bran, is known to possess a potent antioxidant activity, thereby protecting cells from oxidative stress. In the present study, we show that in addition to its known anti-oxidant activity, ferulic acid exerts substantial inhibitory activity on cellular mammalian target of rapamycin (mTor)-signaling pathways. In H...

background: recombinant proteins overexpressed in e. coli are usually deposited in inclusion bodies. cysteines in the protein contribute to this process. inter- and intra- molecular disulfide bonds in chitinase, a cysteine-rich protein, cause aggregation when the recombinant protein is overexpressed in e. coli. hence, aggregated proteins should be solubilized and allowed to refold to obtain nat...

background : boophilus annulatus is an obligate blood feeder tick that can cause great losses in animals due to anemia and its ability to injure its host skin directly. the aim of this study was identification of cattle humoral immune response to some tick proteins during experimental infestation. methods : immune sera against tick were collected from experimentally infested cattle with ticks. ...

Cells must regulate the abundance and activity of numerous nutrient transporters in different organelle membranes to achieve nutrient homeostasis. As the recycling center and major storage organelle, lysosomes are essential for maintaining nutrient homeostasis. However, very little is known about mechanisms that govern the regulation of its membrane proteins. In this study, we demonstrated that...

Nutrient and water uptake from the soil is essential for plant growth and development. In the root, absorption and radial transport of nutrients and water toward the vascular tissues is achieved by a battery of specialized transporters and channels. Modulating the amount and the localization of these membrane transport proteins appears as a way to drive their activity and is essential to mainta...

This study explores the methodology of various experimental vaccines and their immunogenicity outcome in detail. The idea is to give to the reader a picture of the research methodology behind vaccine development that was used in this research. The novelty of this study bases on the demonstration of the cause and effect of antibodies produced against bacterial and viral proteins (immunogens) as ...
