The most common inactivation mechanism of tumor suppressor genes, RASSF1A and p16INK4a, in lung cancer is hypermethylation. We detected the methylation status of RASSF1A and p16INK4a in serum of lung cancer patients using methylation-specific PCR and analyzed their clinicopathological significance. Each of RASSF1A and p16INK4a hypermethylation was detected in 31.1% cancer patients but not in benign lung lesion patients. Hypermethylation was preferentially observed in small cell lung cancer (SCLC) for RASSF1A (50%), but not for p16INK4a...

Thyroid peroxidase (TPO) is the key enzyme in the biosynthesis of thyroid hormones T3 and T4. Autoimmune thyroiditis is a common disorder affecting 10% of population worldwide. A key feature of autoimmune thyroiditis is the presence of anti TPO antibodies, and some mutation of the TPO gene. Association between autoimmune thyroiditis and other autoimmune disorders has been reported but little is known about association with allergic diseases. In this study, we aimed to evaluate frequency of hidden autoimmune thyroiditis among allergic patient and examine possible relationship between anti-TPO levels and polymorphism at the TPO gene A2173/C exon 12 and different types of allergens...
