Using immunochemical techniques, alkaline phosphatase isoenzymes were determined in tissue samples of breast carcinomas and carcinomas of the gastrointestinal tract. In breast carcinomas only 19% of the patients expressed significant placental alkaline phosphatase activity, compared with 78% in gastrointestinal tumours. The intestinal isoenzyme was found in 50% of the breast carcinomas and in n...

AIMS AND BACKGROUND Metastatic colorectal cancer has a heterogeneous behavior, and a set of patients will have minimal response and rapid disease progression. To understand this heterogeneity, studies have evaluated biological and clinical prognostic factors. Alkaline phosphatase seems to be a key prognostic factor, so we have reviewed the outcomes of our patients with respect to alkaline phosp...

We have isolated a set of complementary DNA (cDNA) clones that together encode the alkaline phosphatase of human colon cancer LS174T cells. These clones include two cDNAs isolated from a conventionally prepared oligodeoxythymidylate-primed lambda ZAP cDNA library and three cDNA clones prepared by using the polymerase chain reaction. The deduced amino acid sequence of the alkaline phosphatase pr...

To determine whether decreased alkaline phosphatase activity in the granules from neutrophils of patients with chronic myelogenous leukemia (CML) was due to an absence of enzyme or the production of defective enzyme, we compared the immunologic properties of granule alkaline phosphatase derived from patients with CML with that of normal subjects and patients with polycythemia vera (PRV). Antise...

Alkaline phosphatase prepared from mammalian cell cultures was found to have alkaline inorganic pyrophosphatase activity. Both of these activities appear to be associated with a single protein, as demonstrated by: (1) concomitant purification of alkaline phosphatase and alkaline inorganic pyrophosphatase; (2) proportional precipitation of alkaline phosphatase and inorganic pyrophosphatase activ...

To determine whether decreased alkaline phosphatase activity in the granules from neutrophils of patients with chronic myelogenous leukemia (CML) was due to an absence of enzyme or the production of defective enzyme, we compared the immunologic properties of granule alkaline phosphatase derived from patients with CML with that of normal subjects and patients with polycythemia vera (PRy). Antise...

RATIONALE Decreased alkaline phosphatase activity after infant cardiac surgery is associated with increased post-operative cardiovascular support requirements. In adults undergoing coronary artery bypass grafting, alkaline phosphatase infusion may reduce inflammation. Mechanisms underlying these effects have not been explored but may include decreased conversion of extracellular adenine nucleot...

Plasma alkaline phosphatase and inorganic phosphorus levels were determined for 52 nestling Spanish imperial eagles from two wild populations and 22 captive adults and subadults (10 adults and 12 subadults). The exact age was known for all birds. Mean alkaline phosphatase and inorganic phosphorus were higher in chicks than in the captive adults and subadults. Sex differences were not observed, ...
