Proteins are likely to organize into complexes that assemble and disassemble depending on cellular needs. When approximately 800 yeast strains expressing GFP-tagged proteins were grown to stationary phase, a surprising number of proteins involved in intermediary metabolism and stress response were observed to form punctate cytoplasmic foci. The formation of these discrete physical structures wa...

Vascular endothelial growth factors (VEGFs) are the family of extracellular signaling proteins involved in processes angiogenesis. VEGFA overexpression and altered regulation pathways lead to pathological angiogenesis, which contributes progression various diseases, such as age-related macular degeneration cancer. Monoclonal antibodies decoy receptors have been extensively used anti-angiogenic ...

Accumulating lines of evidence suggest a possibility that glycine is useful as an immuno-modulating amino acid. Glycine most likely prevents the lipopolysaccharide (LPS)-induced elevation of intracellular Ca(2+) concentration in Kupffer cells, thereby minimizing LPS receptor signaling and cytokine production. Moreover, it was reported that dietary glycine inhibits the growth of tumors. Vascular...

The raptor-mTOR protein complex is a key component of a nutrient-sensitive signaling pathway that regulates cell size by controlling the accumulation of cellular mass. How nutrients regulate signaling through the raptor-mTOR complex is not well known. Here we show that a redox-sensitive mechanism regulates the phosphorylation of the raptor-mTOR effector S6K1, the interaction between raptor and ...

this study was carried out to determine the protein and carbohydrate molecular structure of sorghum cultivars using fourier transform infrared spectroscopy (ftir) with multivariate molecular spectroscopy analyses. sorghum cultivars included: 1- kimia, 2- sepideh, 3- m2 and 4- m8. protein and carbohydrate molecular functional groups studied included: peak area and height amide i, amide ii, α-hel...

A majority of oral cancers is squamous cell carcinoma and tongue carcinomas comprise 30% of all oral cancers. Phytochemicals, herbal and dietary antioxidants have been reported to prevent cancers. A nutrient mixture containing, ascorbic acid, lysine, proline and green tea extract, among other nutrients, has previously been shown to exhibit a broad spectrum chemo preventative and therapeutic ant...

Bacteria and their associated bacteriophages are in a continuous battle, co-evolving defence, offence mechanisms. Bacterial xenogeneic silencers, H-NS family proteins, play important roles bacterial phage defence evolution by silencing incoming genes acquired through horizontal gene transfer. It is anticipated that the repression of these directly dependent on DNA binding modes proteins. protei...
