Background and Purpose: Surviving is one of the eight members of the human inhibitors of apoptosis (IAP), which appears to be differentially expressed in cancer cells. This study was conducted to evaluate the clinical usefulness of survivin immunostaining to distinguish between follicular adenoma and carcinoma of thyroid.
Methods and Materials: This study was a cross-sectional descriptive-analytical research. The study population was tissue samples from surgery patients at Shariati Hospital in Tehran, Iran. All samples were studied through immunohistochemical staining for surviving.
Results: Surviving expression was significantly (p

Background and Purpose: Serum soluble Fas (sFas) is found in low concentrations in the sera of healthy subjects and it elevated in patients with autoimmune diseases, malignancy and inflammatory diseases. The Fas molecules play some role in the pathogenesis of Graves’ disease through interfering with the Fas-FasL interaction. Therefore, this study was conducted to evaluate the relationship between soluble Fas serum level and thyroid autoantibodies.
Methods and Materials: In order to determine the association of serum sFas level with thyroid autoantibodies, we evaluated the serum levels of sFas and thyroid antibodies in 31 untreated GD patients and 37 respective healthy controls.
Results: sFas serum level was reported to be higher in patients than in healthy subjects (P

Background and purpose: Vitamin D is an antiproliferative agent against cancer cells and regulates cell differentiation. It acts via Vitamin D Receptor (VDR). The VDR gene contains a Start Colon Polymorphism (SCP) that can be detected with the restriction enzyme Fok I. Previous studies report an association of SCP and some diseases and some suggest that this polymorphism alters VDR function. As no studies so far have reported the association between Fok I genotype in Thyroid cancer, this study is intended to determine the association of Fok I polymorphism of VDR with thyroid cancer risks in Iranian population.
Methods and Materials: 58 patients with papillary carcinoma, 13 patients with follicular carcinoma and 82 controls participated in a case-control study. A PCR-RFLP method used to determine VDR gene polymorphism in start codon characterized by the restriction enzyme Fok I. 95% confidence intervals and odds ratio were calculated for testing the relationship between Fok I polymorphism and thyroid cancer.
Results: The odds ratio for the Fok I polymorphism on thyroid cancer was 0.39 (95% CI, 0.12-1.27), witch signifies no relationship between this polymorphism and the ris of thyroid cancer.
Conclusion: As no relationship was found between this polymorphism and thyroid cancer, other genetic or environmental factors may be considered in thyroid cancer.
