Prophylactic inhalation of L-alanyl-L-glutamine enhances heat shock protein 72 and attenuates endotoxin-induced lung injury in rats.
Studies have demonstrated that heat shock protein 70 (HSP70) plays an important role in the protection of stressed organisms. The development of strategies for enhancing HSPs expression may provide novel means of minimizing inflammatory lung conditions, such as acute lung injury. This study aimed to examine the effect of L-alanyl-L-glutamine (GLN) inhalation in enhancing pulmonary HSP72 (induci...
متن کاملHypertension, aging, and myocardial synthesis of heat-shock protein 72.
We determined the temperature-induced synthesis of the 72-kD heat-shock protein (hsp72) in hearts of normotensive and spontaneously hypertensive rats (SHR) subjected to whole-body hyperthermia (42.0 +/- 0.5 degrees C for 15 minutes). The animals were studied at three different ages: young (2 months), adult (6 months), and old (18 months). The hsp72 was determined by Western blot analysis using ...
متن کاملPAD4-deficiency does not affect bacteremia in polymicrobial sepsis and ameliorates endotoxemic shock.
Neutrophil extracellular traps (NETs), consisting of nuclear DNA with histones and microbicidal proteins, are expelled from activated neutrophils during sepsis. NETs were shown to trap microbes, but they also fuel cardiovascular, thrombotic, and autoimmune disease. The role of NETs in sepsis, particularly the balance between their antimicrobial and cytotoxic actions, remains unclear. Neutrophil...
متن کاملAlanyl-glutamine and glutamine plus alanine supplements improve skeletal redox status in trained rats: involvement of heat shock protein pathways.
AIMS We hypothesized that oral l-glutamine supplementations could attenuate muscle damage and oxidative stress, mediated by glutathione (GSH) in high-intensity aerobic exercise by increasing the 70-kDa heat shock proteins (HSP70) and heat shock factor 1 (HSF1). MAIN METHODS Adult male Wistar rats were 8-week trained (60-min/day, 5 days/week) on a treadmill. During the last 21 days, the animal...
متن کاملContrast Ultrasound Imaging Does Not Affect Heat Shock Protein 70 Expression in Cholesterol-Fed Rabbit Aorta.
OBJECTIVES Diagnostic ultrasound imaging is enhanced by the use of circulating microbubble contrast agents (UCAs), but the interactions between ultrasound, UCAs, and vascular tissue are not fully understood. We hypothesized that ultrasound with a UCA would stress the vascular tissue and increase levels of heat shock protein 70 (Hsp70), a cellular stress protein. METHODS Male New Zealand White...
