Serum levels of insulin-like growth factors (IGF-1 and IGF-2), IGF-binding proteins (IGFBP-1, IGFBP-2, and IGFBP-3) and vascular endothelial growth factor (VEGF) were measured by standard ELISA technique in 95 primary colorectal cancer patients and 48 healthy individuals. Significant increase in serum levels of IGF-1, IGFBP-2, and VEGF and decrease in(More)
The content of MMP-8 and MMP-9 in oral fluid of 145 patients (95 women and 50 men, 18-52 years) was measured by enzyme immunoassay. We examined 63 subjects with the intact periodontium and 82 patients with chronic generalized periodontitis (25 patients with mild disease, 45 patients with moderate disease, and 12 patients with severe disease). All patients(More)
The levels of EGFR and its ligands have been assayed in tumor and adjacent lung tissues in NSCLC patients. Both EGFR and EGF-like peptides were found in tumor more frequently than in unaltered tissue. It was shown (Kaplan-Meyer) that simultaneous expression of EGFR and its ligands in tumor and adjacent lung tissues was associated with lower overall and(More)
Radioligand assay demonstrated that in patients with non-small-cell lung cancer, expression of epidermal growth factor receptors in the tumor is higher than in non-tumor tissue. Expression of epidermal growth factor receptors in tumor and non-tumor lung tissue does not correlate with the stage and metastasizing of the disease and tumor histology. It is also(More)
Estradiol and progesterone cytosol receptors, tamoxifen relative binding capacity in endometrial tissue samples, serum estradiol and progesterone levels were studied in 60 postmenopausal patients with hyperplastic processes in the endometrium. Estradiol and progesterone receptor levels were increased in glandular cystic polyp tissue, in atypical(More)
Investigators and clinicians have recently called attention not only to the clinical and morphological parameters, but to the parameters characterizing the biological activity of nonsmall-cell carcinoma of the lung (NSCCL) from biochemical and molecular biological points of view. These include production of epidermal growth factor (EGF) receptors (EGFR) and(More)
The content of receptors for the epidermal growth factor and estrogens is studied in primary human bone tumors: osteogenic sarcoma, chondrosarcoma, malignant fibrous histiocytoma, and giant cell tumor. In all of these tumors, radioligand analysis reveals receptors for epidermal growth factor in the membrane fraction and receptors for estrogens in the(More)
The content of components of the RANK/RANKL/OPG system, the key regulator of homeostasis in the bone tissue, in blood serum samples from 199 patients with primary bone neoplasms and 131 practically healthy volunteers was measured by ELISA. Borderline giantcell tumor of the bone with high osteoclastogenic and osteolytic activity is characterized by an(More)
