DNA methylation of human endogenous retrovirus in systemic lupus erythematosus.

Previous studies have reported that T cells from active systemic lupus erythematosus (SLE) patients contained global hypomethylation and demethylation at the promoter of several genes, which may contribute to the pathogenesis of the disease. Currently there are scarce data on methylation of retroelements in patients with SLE. We estimated and compared the methylated levels of human endogenous retroviruses (HERV)-E and HERV-K in normal and SLE CD3+CD4+ T lymphocytes, CD8+ T and B lymphocytes by using combined bisulfite restriction analysis-interspersed repetitive sequences (COBRA-IRS).

Phylogenetic analysis of serine proteases from Russell's viper (Daboia russelli siamensis) and Agkistrodon piscivorus leucostoma venom.

Serine proteases are widely found in snake venoms. They have variety of functions including contributions to hemostasis. In this study, five serine proteases were cloned and characterized from two different cDNA libraries: factor V activator (RVV-V), alpha fibrinogenase (RVAF) and beta fibrinogenase (RVBF) from Russell's viper (Daboia russelli siamensis), and plasminogen activator (APL-PA) and protein C activator (APL-C) from Agkistrodon piscivorus leucostoma.
