A single step ion-exchange chromatography on a sulfo-propyl (SP)- Sepharose column was performed to separate both the high molecular weight (HMW)- and low molecular weight (LMW)- forms of enzymatically active urokinase type plasminogen activator from human kidney (HT1080) cell culture media. The level of urokinase secreted by the cell line reached to about 145 Plough units/ml culture broth with...

Marker assisted selection (MAS) is a tool for breeding, screening, and genetic characterization of germplasm. Allelic variation of both high and low molecular weight glutenin subunits (HMW/LMW-GS) is associated with the rheological properties of wheat flour. In this study, we investigated glutenin pattern using SDS-PAGE and their PCR based on DNA markers in 60 advanced wheat lines and cultivars...

The antidiabetic hormone adiponectin circulates in blood as several oligomeric complexes, and the ratios between them are critical in determining insulin sensitivity. In this study we investigated the role of testosterone in regulating the oligomeric complex distribution of adiponectin. Gel filtration analysis revealed that circulating adiponectin existed as the forms of high molecular weight (...

BACKGROUND AND AIMS The trafficking of proteins in the endoplasmic reticulum (ER) of plant cells is a topic of considerable interest since this organelle serves as an entry point for proteins destined for other organelles, as well as for the ER itself. In the current work, transgenic rice was used to study the pattern and pathway of deposition of the wheat high molecular weight (HMW) glutenin s...

To detect integration of a transgene in genetically modified plants that have a native copy of the gene, a simple and reliable PCR-based method has been established. This method is then used to screen for transgenic wheat plants that have been transformed with the high molecular weight glutenin subunit Dy10 gene. Two PCR primers were designed, the forward one matched upstream flanking nucleotid...

Cyclic nucleotide phosphodiesterase 3A (PDE3) regulates cAMP-mediated signaling in the heart, and PDE3 inhibitors augment contractility in patients with heart failure. Studies in mice showed that PDE3A, not PDE3B, is the subfamily responsible for these inotropic effects and that murine PDE3A1 associates with sarcoplasmic reticulum Ca(2+) ATPase 2 (SERCA2), phospholamban (PLB), and AKAP18 in a m...

Genetic and environmental factors that affect the formation of glutenin macropolymer (GMP) particles were investigated by growing Lance 5C 10, Lance 2C12, Warigal 5C10 and Warigal 2C12 lines under widely differing temperature regimes in greenhouse conditions. The GMP characteristics and mixing properties of flour extracted from mature wheat kernels were systematically studied. The amount of GMP...
