Physiological hemostatic balance is a coordinated outcome of counteracting coagulation and fibrinolytic systems. An imbalance of procoagulant and anticoagulant factors may result in life threatening thromboembolism. Presently, anticoagulant administration is the first line of therapy for the treatment of these conditions and several anticoagulants have been approved, including various forms of ...

The effect of intracellular trehalose and glycogen on the survival of spores of Dictyostelium discoideum ATCC 25697 after exposure to supraoptimal temperatures was examined. Cells metabolically perturbed by incubation in glucose and inorganic phosphate have intracellular trehalose and glycogen concentrations fivefold and twofold higher, respectively, than those of the controls. These cells were...

The impact of abiotic stress on plant growth and development has been and still is a major research topic. An important pathway that has been linked to abiotic stress tolerance is the trehalose biosynthetic pathway. Recent findings showed that trehalose metabolism is also important for normal plant growth and development. The intermediate compound - trehalose-6-phosphate (T6P) - is now confirme...

Spermatogonial stem cells provide the foundation for continued adult spermatogenesis and their manipulation can facilitate assisted reproductive technologies or the development of transgenic animals. Because the pig is an important agricultural and biomedical research animal, the development of practical application techniques to manipulate the pig Spermatogonial stem cell is needed. The abilit...

The detection of tuberculosis currently relies upon insensitive and unspecific techniques; newer diagnostics would ideally co-opt specific bacterial processes to provide real-time readouts. The trehalose mycolyltransesterase enzymes (antigens 85A, 85B and 85C (Ag85A, Ag85B, Ag85C)) serve as essential mediators of cell envelope function and biogenesis in Mycobacterium tuberculosis. Through the c...

The aim of the study was to investigate the role of trehalose in ethanol induced oxidative stress condition in yeast Pachysolen tannophilus. The laboratory experiments were carried out during 2009 and 2010 at the Yeast Stress Response Study Laboratory of Biochemistry Department in Panjab University at Chandigarh, India. Resistance of the yeast Pachysolen tannophilus to ethanol stress was studie...

Plant abiotic stress tolerance has been modulated by engineering the trehalose synthesis pathway. However, many stress-tolerant plants that have been genetically engineered for the trehalose synthesis pathway also show abnormal development. The metabolic intermediate trehalose 6-phosphate has the potential to cause aberrations in growth. To avoid growth inhibition by trehalose 6-phosphate, we u...

Originally, trehalose was believed to function only as a reserve carbohydrate similar to glycogen. It is now known that the degradation of trehalose yields little energy and whilst it can serve as a source of carbon skeletons for biosynthesis, it mainly functions as a membrane stabiliser and protectant for yeast cells under stress. (O'Connor-Cox et al, 1996). The significance of trehalose as an...

The TPS1 gene from Hansenula polymorpha, which encodes trehalose-6-phosphate (Tre6P) synthase, has been isolated and characterized. The deletion of TPS1 rendered H. polymorpha cells incapable of trehalose synthesis under conditions where wild-type cells normally accumulate high levels of trehalose. Interestingly, the loss of Tre6P synthase did not cause any obvious growth defects on a glucose-c...

Eukaryotes able to withstand desiccation enter a state of suspended animation known as anhydrobiosis, which is thought to require accumulation of the non-reducing disaccharides trehalose (animals, fungi) and sucrose (plants), acting as water replacement molecules and vitrifying agents. We now show that clonal populations of bdelloid rotifers Philodina roseola and Adineta vaga exhibit excellent ...
