After Warburg stated his hypothesis on tumor cell metabolism about 80 years ago, the field of carbohydrate metabolism of cancer cells and solid tumors is experiencing a boom for the past few years. Numerous studies have been focused on the characteristics of cancer metabolism and its accessibility to novel therapeutic interventions. Malignant transformation is associated with an increase in glycolytic flux, mainly caused Read More

In addition to the key role of thrombin in blood coagulation, this multifunctional serine protease activates platelets and regulates the behavior of other cells through G-protein coupled protease activated receptors (PARs). PAR-1 is the principal thrombin-activated receptor involved in platelet aggregation and in endothelial and tumor cell proliferation. PAR-1 is overexpressed in invasive and metastatic tumors and the expressio Read More

The aim of this study was to evaluate the potential anticancer properties and modulatory effect of selected Aloe vera (A. vera) active principles on antioxidant enzyme activities. Thus, three anthraquinones (Namely: aloesin, aloeemodin and barbaloin) were extracted from A. vera leaves by supercritical fluid extraction and subsequently purified by high performance liquid chromatography. Additionally, the N-terminal octapep Read More

The farnesoid X receptor (FXRα) is a metabolic nuclear receptor and bile acid sensor expressed in the liver and intestine. Physiological studies have shown that FXR.. exerts regulatory roles in bile acids, lipid and glucose homeostasis. FXR ligands of steroidal and non-steroidal structure have been described. Both ligand groups have shown limitations in preclinical studies regarding their absorption, metabolism, target interactions an Read More

Since its discovery in 2000, neuroglobin (Nb) has been demonstrated to have an essential and conserved function in vertebrates with the consequential discovery of a neuroprotective role. Nb is a member of the globin superfamily and is predominantly expressed in neurons of the central and peripheral nervous system. Thorough studies have been performed to elucidate the molecular structure of Nb and its ligand Read More

DNA exhibits many attractive features in the development of drug design and disease treatment, and there are some successful events for drugs targeting to DNA in clinic use. Nowadays, the specific recognition of DNA by small molecules is the crucial factor of the sustainable development of DNA-target drugs, for the serious side-effects of existing drugs. In this review, we discussed the current efforts of DNA-drug specific inte Read More
