OBJECTIVE To determine if serum amyloid A (A-SAA) could be detected in human osteoarthritic (OA) joints and further clarify if high A-SAA level in joints result from a local production or from a diffusion process from abnormally elevated plasma concentration. Regulatory mechanism of A-SAA expression and its pro-inflammatory properties were also investigated. METHODS A-SAA levels in serum and ...
The impact of immune system stimulation (ISS) on the ileal nutrient digestibility and utilisation of dietary methionine plus cysteine (SAA) intake for whole-body protein deposition (PD) was evaluated in growing pigs. For this purpose, sixty barrows were used in two experiments: thirty-six pigs in Expt I and twenty-four pigs in Expt II. Pigs were feed restricted and assigned to five levels of di...
AIMS High-density lipoproteins (HDLs) are considered as anti-atherogenic. Recent experimental findings suggest that their biological properties can be modified in certain clinical conditions by accumulation of serum amyloid A (SAA). The effect of SAA on the association between HDL-cholesterol (HDL-C) and cardiovascular outcome remains unknown. METHODS AND RESULTS We examined the association o...
New tools are needed to detect chronic sub-clinical mastitis, especially in automatic milking systems. Haptoglobin and serum amyloid A (SAA) are the two most sensitive bovine acute phase proteins, and their concentrations increase in milk from cows with clinical mastitis and in milk from cows with experimentally induced chronic sub-clinical Staphylococcus aureus mastitis. The aim of this study ...
BACKGROUND Acute-serum Amyloid A (A-SAA), one of the major acute-phase proteins, is mainly produced in the liver but extra-hepatic synthesis involving the skin has been reported. Its expression is regulated by the transcription factors NF-κB, C/EBPβ, STAT3 activated by proinflammatory cytokines. OBJECTIVES We investigated A-SAA synthesis by resting and cytokine-activated Normal Human Epiderma...
Amyloid fibrils deposited in secondary amyloidosis contain a unique protein (AA) as the major constituent (1-3). An antigenically related serum protein (SAA) (4, 5), present in normal sera in low concentration (6), is elevated in amyloidosis and in diseases which predispose to amyloidosis, such as rheumatoid arthritis, leprosy, and tuberculosis (4-8). The finding that SAA has a monomeric form a...
The objective of this study was to evaluate the effect of storage under various conditions on the concentrations of major bovine acute phase protein-serum amyloid A, and its mammary isoform. Blood samples were taken from seven clinically healthy calves, and milk samples from six clinically healthy dairy cows. The harvested blood serum and the milk samples were fractioned into aliquots. One aliq...
BACKGROUND Elevated C-reactive protein (CRP) is associated with adverse outcomes in non-ST-segment elevation acute coronary syndromes (NSTE-ACS); however, the prognostic significance of serum amyloid A (SAA), also an important inflammatory marker, remains unclear. METHODS AND RESULTS The ability of SAA, in combination with CRP, to predict clinical outcomes was evaluated in 277 patients with N...
The acute-phase protein serum amyloid A (SAA) is commonly considered a marker for inflammatory diseases; however, its precise role in inflammation and infection, which often result in neutrophilia, remains ambiguous. In this study, we demonstrate that SAA is a potent endogenous stimulator of granulocyte colony-stimulated factor (G-CSF), a principal cytokine-regulating granulocytosis. This effec...
