Wild-type Wilms' tumor gene WT1 is highly expressed not only in hematopoietic malignancies, including leukemia and myelodysplastic syndromes (MDS), but also in various kinds of solid tumors. Human cytotoxic T lymphocytes (CTLs) which could specifically lyse WT1-expressing tumor cells with HLA class I restriction were generated in vitro. We have also demonstrated that mice immunized with the WT1 peptide or WT1 cDN Read More

Mammalian terminal deoxyribonucleotidyl transferase (TDT) catalyzes the non-template-directed polymerization of deoxyribonucleoside triphosphates and has a key role in V(D)J recombination during lymphocyte and repertoire development. Over 90% of leukemic cells in acute lymphocytic leukemia and approximately 30% of leukemic cells in the chronic myelogenous leukemia crisis show elevated TDT activity. T Read More

Enfuvirtide (Fuzeon®, Roche), is the first member of a novel class of antiretroviral agents, the socalled fusion inhibitors, which act against HIV with a completely novel (extra cellular) mechanism of action, and can therefore be easily added to all anti-HIV association therapies including all other antiretroviral agents belonging to nucleoside/nucleotide reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, Read More

The enzyme protein:geranylgeranyl transferase-1 (PGGT-1 or GGTase-I) catalyzes the geranylgeranylation of cysteine residues near the C-termini of a variety of proteins, including most monomeric GTP binding precursor proteins belonging to the Rho, Rac and Rap subfamilies. These proteins are involved in signaling pathways controlling important processes such as cell differentiation and growth. In the framework of the develop Read More

The arsenal of drugs in the fight against AIDS is rapidly diminishing as the HIV becomes resistant to the available reverse transcriptase and protease inhibitors. After killing millions all over the world, the virus is still on the rampage and hence the pharmaceutical industry is resorting to the development of inhibitors of integrase. This seems to be the last arrow in the quiver of potential drug leads to combat the deadly infecti Read More

Cardiovascular disease (CVD) is the leading cause of death among patients with end-stage renal disease (ESRD). Vitamin D deficiency accompanies the loss of kidney function and is extremely common. Treatment with active vitamin D has improved survival rate in dialysis patients. The relationship between vitamin D and CVD has been reported in the literature. Genetic factors have been known to cause both vitamin D d Read More

Despite the fact that they have been used for a century to treat several kinds of diseases, peptides and short proteins are now considered the new generation of biologically active tools. Indeed, recent findings suggest a wide range of novel applications in medicine, biotechnology, and surgery. The efficacy of native peptides has been greatly enhanced by introducing structural modifications in the original sequences, giving rise t Read More
