Toll Like Receptor 3 Polymorphisms in Hepatitis B Virus Infection.

Hepatitis B virus (HBV) is the one of the major causes of chronic liver disease. Individuals exposed to HBV show wide spectrum outcomes including immunized persons, asymptomatic carrier, chronic active hepatitis, cirrhosis and HCC. The outcome of HBV infection and the severity of associated liver diseases are determined by the nature and strength of host immune responses against the virus.

Diagnostic Role of RASSF1A and p16INK4a Promoter Gene Hypermethylation in Serum DNA of Lung Cancer Patients: Clinicopathological Significance.

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.

Single nucleotide polymorphism T869C of transforming growth factor-beta 1 gene and systemic lupus erythematosus: association with disease susceptibility and lupus nephritis.

Transforming growth factor β1 (TGF-β1) has a large role in the control of autoimmunity. Single nucleotide polymorphisms (SNP) in the promoter of TGF-β1 cytokine gene are known to alter the production of this important cytokine. Decreased levels of TGF-β1 may contribute to systemic lupus erythematosus (SLE) susceptibility, activity and organ damage.
