In this study Escherichia coli DE3 containing expression vector (pET21a) with cloned Persian sturgeon growth hormone (psGH) gene was grown in 10 mL LB broth on a 150 rpm shaker, at the temperature of 37 °C. At the late log phase (determined by OD standard curve) 100 &muL isopropyl &beta-D-1-thiogalactopyranoside (IPTG) was added for induction of GH synthesis. Samples were taken every 2 hours an...

Protein aggregation is phenomenon wherein protein loses its native structure and aggregates due to the adaption of non-native conformation. Amyloid aggregation formed by the accumulation of various proteins causes many diseases in humans and other organisms. Antioxidants can prevent proteins aggregation. Pulicaria undulata  extract along with phenolic compounds can increase protein stability an...

Neonatal purpura fulminans is a rare and life threatening disease that can be inherited or acquired in etiology. It manifests as DIC and extensive subcutaneous thrombosis. The condition is often fatal unless there is prompt diagnosis, and judicious therapy. The most important causes of this condition are infections and congenital deficiency of anticoagulant proteins C and S.In the case of PC (p...

The interaction between proteins and membranes has an important role in biological pro-cesses.We have calculated energies of interaction between Melittin and DMPC bilayer in differenttemperatures. We have used the CHARMM software for MD simulation under the canonical (N,V, E) ensemble at different temperatures. The computations have shown that water moleculeshave more penetration into the bilay...

We investigated protein and gene expression in the lag phase of Lactococcus lactis subsp. lactis CNRZ 157 and compared it to the exponential and stationary phases. By means of two-dimensional polyacrylamide gel electrophoresis, 28 highly expressed lag-phase proteins, implicated in nucleotide metabolism, glycolysis, stress response, translation, transcription, cell division, amino acid metabolis...

Objective: The effects of 6-MSITC on cell cycle progression were investigated in quiescent mouse epidermal JB6 cells.
 Background: 6-Methylsulfinylhexyl isothiocyanate (6-MSITC) derived from wasabi (Wasabia japonica) has been reported to prevent tumor development vivo.
 Material and methods: Treatment with growth factor (EGF) cells, which serum-starved for 36 h, promoted the G0/G1 pha...

Abstract Understanding the kinetics, thermodynamics, and molecular mechanisms of liquid–liquid phase separation (LLPS) is paramount importance in cell biology, requiring reproducible methods for studying often severely aggregation-prone proteins. Frequently applied approaches inducing LLPS, such as dilution protein from an urea-containing solution or cleavage its fused solubility tag, lead to v...

A solution of the nonionic detergent Triton X-114 is homogeneous at 0 degrees C but separates in an aqueous phase and a detergent phase above 20 degrees C. The extent of this detergent phase separation increases with the temperature and is sensitive to the presence of other surfactants. The partition of proteins during phase separation in solutions of Triton X-114 is investigated. Hydrophilic p...
