The effects of the nonsteroidal antiandrogen bicalutamide (Casodex(TM)) and the luteinizing hormone releasing hormone agonist leuprolide depot (Procren Depot(TM), Lupron Depot(TM)) on serum prostate-specific antigen (PSA), acid phosphatase (ACP), and prostatic acid phosphatase (PAP) in patients with
The effect of 5alpha-dihydrotestosterone (DHT) on the level of human prostatic acid phosphatase (hPAP) mRNA was studied using tissue slices from various benign prostatic hyperplastic glands. The absence of DHT in the incubation medium led to a gradual, significant decrease of the hPAP mRNA level.
Accurate phosphorylation of tyrosine residues in proteins plays a central role in regulation of cellular function. Although connections between aberrant tyrosine kinase activity and malignancy are well-established, significantly less is known about the roles of protein tyrosine phosphatases
We examined the incidence of prostatic cancer in patients with an elevated radioimmunoassay for prostatic acid phosphatase and clinical benign prostatic hyperplasia on digital rectal examination. Of 295 patients screened with prostatic acid phosphatase tests 17 fulfilled the criteria of having an
Acid phosphatase activity biochemically in the primary tumor of 20 patients with prostatic carcinoma, was studied in an attempt to understand the basis for a correlation or lack of correlation between serum and/or bone marrow acid phosphatase levels and the presence and/or clinical behavior of
Studies were made on the urinary bladder of 66 BALB/c mice of both sexes; 21 were fed a normal diet and 45, a diet containing 100-500 parts per million (ppm) of 2-acetylaminofluorene (2-AAF). Bladder epithelial hyperplasia was noted in 22 of 24 mice given 2-AAF for 7 months and in 20 of 21 given
Prostate specific acid phosphatase (PAP) (Abbott, solid-phase enzyme immunoassay) and prostate specific antigen (PSA) (Hybritech, immunoradiometric assay) were determined in 162 newly diagnosed prostatic carcinoma patients, 187 patients with benign prostatic hyperplasia (BPH) and 127 controls. The
Serum acid phosphatase levels were determined in 247 men with surgically confirmed intracapsular prostatic cancer (30 patients), benign prostatic hyperplasia (BPH) (114 patients) or palpably normal prostates (103 men). Both radioimmunoassay (245 cases) and an enzymatic method (218 cases) were used.
Acid phosphatase isozymes were investigated in cancerous prostatic tissue (4 cases) and benign prostatic hyperplasia (6 cases). Electron-microscopic histochemical examination of cancer tissue revealed irregular acid beta-glycerophosphatase staining in various cell organelles, including the plasma
Phosphate load accelerates the progression of secondary hyperparathyroidism (sHPT). In advanced stages of sHPT, there is a marked hyperplasia and resistance to classical regulatory endocrine factors such as calcium, calcitriol, or fibroblast growth factor 23 (FGF23), which suppresses PTH secretion
The objective of our study was to evaluate the phosphatase and tensin homologue deleted on chromosome 10 (PTEN), p27, and mammalian target of rapamycin (mTOR) expressions in women with progesterone-responsive and refractory endometrial hyperplasia (EH) samples and to determine if these markers could
Prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA) are the markers of human prostatic gland. However, it is still not completely understood if and how, steroid hormones and growth factors affect their expression and metabolism in the respect to the major pathologies of the gland.
The significance of glucose-6-phosphatase (G6P) expression by bile duct-like cells proliferating during hepatocarcinogenesis in the histogenesis of hepatocellular carcinoma is not clear. To this end, we measured the histochemical and biochemical activity of G6P in normal rat liver, and in rat livers
OBJECTIVE
We previously found that Dual-specificity phosphatase 6 (Dusp6) over-expression enhanced the growth-promoting effect of estrogen in endometrial adenocarcinoma cells. The aim of this study was to explore the correlation of Dusp6 expression with progestin sensitivity in atypical endometrial
Changes in the levels of serine dehydratase and glucose-6-phosphatase induced by dietary stimuli or starvation in hyperplastic nodules of rat liver during diethylnitrosamine or N-2-fluorenylacetamide feeding were studied by immuno- and enzyme histochemical methods. The study was performed during
