OBJECTIVE
To determine if the intestinal isoenzymes of alkaline phosphatase (ALP) are biochemical markers of bowel necrosis in neonates.
METHODS
Plasma ALP isoenzymes were measured in 22 babies with bowel necrosis, histologically confirmed, and in 22 matched controls. The isoenzymes were also
Tumor necrosis factor-alpha (TNF alpha), a product of activated monocytes, induces tissue wasting in certain solid tumors in vivo and in in vitro model systems. Recent studies indicate that TNF alpha also regulates cell replication and expression of differentiated function in a variety of
Tumor necrosis factor (TNF) alpha and TNF beta both inhibited proliferation of cultured human osteoblastic SaOS-2 cells. TNF alpha also inhibited alkaline phosphatase (ALP) activity in the cells. The TNF alpha-induced inhibition of proliferation and ALP activity was further potentiated by interferon
This study examines the molecular mechanisms of interaction between tumor necrosis factor alpha (TNF alpha) and retinoic acid on the expression of the alkaline phosphatase gene by rat clonal preosteoblastic cells. In this cell line, alkaline phosphatase mRNA was not constitutively expressed but was
METHODS
The present study analyzed the restriction fragment length polymorphism patterns of alpha 2(XI) collagen, bone morphogenetic protein-2, alkaline phosphatase, and tumor necrosis factor-alpha genes in patients with ossification of the posterior longitudinal ligament. This study investigates
Retinoic acid has a specific role in cellular differentiation and is believed to act by regulating the transcription of specific genes. In the present work, evidence is provided to show that alkaline phosphatase (ALP) gene expression is mediated by retinoic acid in a model clonal cell line (UMR 201)
BACKGROUND
In osteosarcoma the histological response, measured by the percentage of tumor necrosis, constitutes one of the most significant predictive factors, with better survival in patients whose tumor necrosis is > or = 90%.
OBJECTIVE
To determine if the decrease rate of serum alkaline
A novel immunosensor for sensitive detection of tumor necrosis factor α was reported. First of all, gold nanoparticles were uniformly assembled on the surface of poly (styrene-acrylic acid) nanospheres, which was used as the matrix to conjugate alkaline phosphatase (ALP). And then, the obtained
Vascular calcification is implicated in many diseases including atherosclerosis and diabetes. Tumor necrosis factor-alpha (TNF-alpha) has been shown to promote vascular calcification both in vitro and in vivo. However, the molecular mechanism of TNF-alpha-mediated vascular calcification has not yet
Inflammatory cells such as macrophages and T lymphocytes play an important role in vascular calcification associated with atherosclerosis and cardiac valvular disease. In particular, macrophages activated with cytokines derived from T lymphocytes such as interferon-gamma (IFN-gamma) may contribute
The modulatory effects of interleukin (IL)-1 beta and tumor necrosis factor (TNF)-alpha on bone morphogenetic protein (BMP)-2- and -4-induced alkaline phosphatase (ALP) activity were examined in cultures of mouse MC3T3-E1 osteoblastic cells. Both BMP-2 and -4 significantly induced ALP in these
OBJECTIVE
Rheumatoid arthritis (RA) and psoriatic arthritis (PsA) are characterized by periarticular bone erosion; periarticular bone formation is a feature in PsA. The effect of anti-tumor necrosis factor-α (TNF-α) on periarticular bone remodeling is unclear in both diseases. Our aim was to assess
Tumor necrosis factor (TNF) -α plays a crucial role in rheumatoid arthritis (RA)-related bone loss disease. The main mechanism of action of RA induced bone loss is the significant inhibitory effect of TNF-α on osteoblast differentiation. TNF-α inhibits osteoblast differentiation mainly by activating
OBJECTIVE
To compare clinicopathological features of acute presentation of type 1 autoimmune hepatitis (AIH) with or without centrilobular necrosis (CN).
METHODS
Our study comprised 41 patients with biopsy-proven acute presentation (acute exacerbation phase 36, acute hepatitis phase 5) of type 1 AIH
