Neuropilins are expressed in tumors vasculature and cells. Their expression is thought to be correlated with tumor angiogenesis and progression. In this study, we analyzed NRP-1 expression level in 40 acute leukemia patients [20 acute myeloid leukemia (AML) and 20 acute lymphoblastic leukemia (ALL)] and 10 healthy controls using Real-Time Quantitative(More)
Background: Genetic variation influencing individual susceptibility to chemical carcinogens is one of the main factors leading to cancer development. The glutathione S-transferases (GSTs) are a family of enzymes belonging to phase II enzymes involved in detoxification of xenobiotics. A significant relationship is observed between the risk of developing(More)
Lung cancer is the second most common malignancy in the USA, and it is the leading cause of cancer-related deaths among men and women. Regulatory T cells (Tregs) in peripheral blood play crucial roles in suppressing antitumor immune responses in cancer patients. A defect in the immune response may contribute to tumor growth. This study was conducted to test(More)
Vitamin D is critical for calcium, phosphate homeostasis and for mineralization of the skeleton, especially during periods of rapid growth. Vitamin D Deficiency leads to rickets (in children) and osteomalacia (in adults). Expression and activation of the vitamin D receptor (VDR) are necessary for the effects of vitamin D, in which several single nucleotide(More)
BACKGROUND Type 1 insulin like growth factor receptor (IGF-IR) is over expressed in many tumors including hematological cancers. It is a critical signaling molecule for tumor cell proliferation and survival. Data suggest that IGF-IR antibodies can effectively and specifically inhibit cancer cell growth in vitro and in vivo. Blockage of IGF-IR expression(More)
Immune thrombocytopenic purpura (ITP) is an autoimmune syndrome involving platelets destruction and suppression of platelet production that may predispose to bleeding. Protein tyrosine phosphatase non-receptor 22 gene (PTPN22) is an important negative regulator of signal transduction through the T-cell receptors (TCR). A single nucleotide polymorphism (SNP)(More)
