Familial Mediterranean fever (FMF) is a recessively inherited disorder that is common in patients of Armenian ancestry. To date, its diagnosis, which can be made only retrospectively, is one of exclusion, based entirely on nonspecific clinical signs that result from serosal inflammation and that may lead to unnecessary surgery. Renal amyloidosis, prevented(More)
FGFR3 and TP53 mutations are frequent in superficial papillary and invasive disease, respectively. We used denaturing high-performance liquid chromatography and sequencing to screen for FGFR3 and TP53 mutations in 81 newly diagnosed urothelial cell carcinomas. Tumors were classified as follows: 31 pTa, 1 carcinoma in situ, 30 pT1, and 19 pT2-T4. Tumor(More)
Familial Mediterranean fever (FMF) is a recessively inherited disorder predisposing to renal amyloidosis and associated with mutations in MEFV, a gene encoding a protein of unknown function. Differences in clinical expression have been attributed to MEFV-allelic heterogeneity, with the M694V/M694V genotype associated with a high prevalence of renal(More)
BACKGROUND Detection of p53 antibodies in serum might be an effective indirect procedure to detect alterations of the p53 gene. AIMS To assess the prevalence and the variation under treatment of p53 antibodies in patients with colorectal cancer. PATIENTS AND METHODS Fifty four patients with colorectal cancer (26 men and 28 women, mean age 65, range(More)
Clinical observations and experimental data suggest that sex hormones influence the development of systemic lupus erythematosus (SLE). An imbalance between androgen and estrogen plasma levels may suggest an abnormality in the aromatase activity involved in estradiol synthesis. Aromatase activity in skin and subcutaneous tissue and plasma sex-hormone levels(More)
The aim of this preliminary study was to evaluate retrospectively sestamibi scintigraphy in relation to the presence of the 170-kDa P-glycoprotein (Pgp), which represents an expression of multidrug resistance in patients with primary breast cancer. Fifteen women (age range 37-76 years) were referred for technetium-99m sestamibi scintigraphy because of(More)
Established human mammary tumor cell lines constitute an important tool in the study of breast cancer. The aim of this work was to isolate and characterize two new mammary tumor cell lines, JCK and GCS, which were obtained from the pleural effusion and ascitic fluid, respectively, from two breast cancer patients. Both cell lines had some properties of(More)
UNLABELLED It was reported recently that 99mTc-hexakis-2-methoxyisobutyl isonitrile (MIBI) uptake is drastically reduced in cancer cells that express the multidrug resistance (MDR) product, Pgp 170 kDa (Pgp), suggesting that 99mTc-MIBI is a transport substrate for this transmembrane glycoprotein. In our study, we explored if another pump, a multidrug(More)
Polyphenols extracted from many plants have shown antiproliferative and antitumor activities in a wide range of carcinogenesis models. The antiproliferative effects of polyphenols purified from the Brazilian aroeira plant (Schinus terebinthifolius, Raddi) were investigated on the androgen-insensitive DU145 human prostatic carcinoma cell line. A F3 fraction(More)
UNLABELLED Early diagnosis of multidrug-resistance (MDR) development is extremely important for the judicious choice of treatment protocols in breast cancer chemotherapy. In this study, the mechanism of 99mTc-sestamibi uptake by nine human breast tumor cell lines was analyzed as a function of P-glycoprotein (PgP) expression. METHODS(More)
