The expression of Fas in thyroid tumours and Graves' disease was analysed by mRNA transcript expression. As compared with unaffected thyroid tissue, Fas expression was enhanced in Graves' disease, adenomas, and papillary and follicular carcinomas. This pattern was also reflected in immunohistochemical studies. The PCR single-strand conformational polymorphism (SSCP) method and DNA sequencing we...
In addition to their capacity for template-directed 5' --> 3' DNA synthesis at the polymerase (pol) site, DNA polymerases have a separate 3' --> 5' exonuclease (exo) editing activity that is involved in assuring the fidelity of DNA replication. Upon misincorporation of an incorrect nucleotide residue, the 3' terminus of the primer strand at the primer-template (P/T) junction is preferentially t...
مطالعات گذشته اثر محافظتی ویتامین d در برابر سرطان پستان را گزارش کردند که این اثر توسط گیرنده ویتامین d (vdr) میانجی گری می شود. شواهد زیادی وجود دارد که نشان می دهد که شیوع سرطان پستان با انواع پلی مورفیسم روی ژن vdr ارتباط دارد. هدف این مطالعه، بررسی ارتباط بین پلی مورفیسم در توالی poly(a) ژن vdr با سطح ویتامین d (25-هیدروکسی ویتامین d) سرم و خطر ابتلا به سرطان پستان می باشد. واکنش چند شکلی ...
Methodology: Seven hypercholesterolemic families were chosen for this study. Case history was taken and pedigree was created in person by visiting every family. Exon3 and exon4 regions of ApoE cistron were amplified using polymerase chain reaction (PCR).After successful amplification, both citrons were sequenced. Single strand conformation polymorphism (SSCP) results were obtained to support th...
