  • Clinical and biological characteristics of clear cell carcinomas of the ovary in FIGO stages I-II
  • 2005
  • Ingår i: International Journal of Oncology. - Athens, Greece : Spandidos Publications. - 1019-6439 .- 1791-2423. ; 26:1, s. 177-183

    • Clear cell carcinoma of the ovary is considered to be a specific subtype among the epithelial ovarian malignancies. To characterize clear cell carcinomas in early FIGO stages (I-II) with regard to clinical and biological properties, a retrospective study was performed to compare these tumors with other histological subtypes. From a complete series of 226 patients with epithelial ovarian carcinomas in FIGO stages I-II, 28 patients with clear cell carcinomas were selected and the clinical and biological characteristics of these tumors were compared with the remaining non-clear cell carcinomas. All patients underwent primary staging laparotomy followed by adjuvant radiotherapy or chemotherapy. The apoptosis regulators p53, bcl-2 and bax, and the growth factor receptors EGFR and HER-2/neu were analyzed by immunohistochemical techniques and DNA analysis was performed by flow cytometry. Clear cell carcinomas stained negative for p53 significantly more often than other histological subtypes. Positive EGFR staining was seen more frequently in serous carcinomas than in the clear cell carcinomas. Aneuploid DNA status was seen more frequently in clear cell carcinomas than in other histological subtypes and tetraploid tumors made up 50% of the non-diploid tumors. Clear cell tumors were frequently (64%) found in FIGO stages IC and IIC and this was more common than for non-clear cell tumors. No difference was found in the rate of tumor recurrences or survival for patients with clear cell and non-clear cell carcinomas. Clear cell carcinomas of the ovary should be regarded as a separate entity among the epithelial ovarian carcinomas and they differ with regard to both clinical and biological characteristics when compared with non-clear cell tumors.

  • Calcium activation of tissue transglutaminase in radioligand binding and enzyme-linked autoantibody immunoassays in childhood celiac disease.
  • 2005
  • Ingår i: Clinica Chimica Acta. - : Elsevier BV. - 0009-8981. ; 358:1-2, s. 95-103
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Conflicting data have been published concerning the effect of calcium on binding of autoantibodies to tissue transglutaminase (tTG) in celiac disease (CD). Methods IgA-tTG and IgG-tTG were measured with radioligand binding assays (RBA) using human recombinant (hr) 35S-tTG produced in lysate of rabbit reticulocytes and with guinea pig (gp) tTG ELISA in 51 CD children (median: 5.7 years) and 35 controls (median: 2.2 years). Assays were performed with and without calcium. Results In hr-tTG RBA, IgA-tTG levels remained unchanged after calcium detecting 50/51 CD children and 1/35 controls (p < 0.0001). IgG-tTG levels decreased with calcium (p < 0.0001) in CD children and detected 48/51 with and 49/51 without calcium as compared to 1/35 controls (p < 0.0001). In gp-tTG ELISA, levels increased with calcium (p < 0.0001) making it possible to detect an additional three to a total of 50/51 with IgA-tTG and 13 to 39/51 CD children with IgG-tTG compared to 4/35 and 8/35 controls (respectively, p < 0.0001). Rabbit reticulocytes displayed calcium-dependent tTG activity. Conclusions Calcium increased binding of IgA-tTG and IgG-tTG in the ELISA test. The reverse effect observed in RBA may be explained by competitive binding between calcium activated native rabbit reticulocyte tTG and hr 35S-tTG. tTG autoantibody assays may need taking calcium into account for accurate diagnostic sensitivity and specificity for CD.

  • Advanced glycation end product is implicated in amyloid-related kidney complications
  • 2005
  • Ingår i: Scandinavian Journal of Clinical and Laboratory Investigation. - : Informa Healthcare. - 0036-5513 .- 1502-7686. ; 65:4, s. 263-272
  • Tidskriftsartikel (refereegranskat)abstract
    • Background. Kidney failure is a common complication in familial amyloidotic polyneuropathy (FAP). It has been suggested that advanced glycation end products (AGEs) play an important role in the development and pathogenesis of FAP.Material and methods. To evaluate the impact of AGEs on FAP patients' kidney dysfunction, we measured AGE in serum and urine of 28 FAP patients and 18 healthy controls by AGE-specific enzyme-linked immunosorbent assay (ELISA). Immunohistochemistry utilizing antibodies to AGE and the receptor for AGE (RAGE) were used on kidney tissue from 3 FAP patients and 3 diabetic patients to disclose a correlation between amyloid deposits and AGE -RAGE.Results. The glomeruli of FAP patients were heavily deposited with amyloid and the glomerular size was enlarged. The space between Bowman's capsule and glomerulus was totally covered by the enlarged glomerulus. AGE and RAGE were deposited in glomeruli and tubuli and correlated with amyloid deposits. Decreased AGE levels in the liver-transplanted FAP patients' serum compared with that of non-transplanted patients were noted, and AGE concentration in serum tended to be higher in non-transplanted FAP patients compared with normal control subjects. There were no differences in the AGE urine levels in FAP patients compared with controls. No correlation could be found between AGE in urine and serum compared with serum albumin, serum creatinine and creatinine clearance.Conclusions. The accumulation of AGE, RAGE and amyloid in the kidney of FAP patients suggests that these molecules play an important role in the origin and pathogenesis of renal failure in FAP patients.
