Pharmacogenomics of thymidylate synthase in cancer treatment.
Cancer drugs such as 5-fluorouracil (5-FU) that target the enzyme thymidylate synthase (TS) have been and are still being widely used in cancer treatment, but as with other anti-cancer drugs, the majority of tumors do not respond to the treatment, whereas the patients still suffer drug-related toxicity. The most recent attempts at improving cancer treatment have taken the pharmacogenetic approa...
متن کاملDickkopf-1 enhances migration of HEK293 cell by beta-catenin/E-cadherin degradation.
Migration is an important process during cellular activity and embryo development. We recently showed that Dickkopf-1(Dkk-1), an antagonist of Wnt/ beta-catenin signaling pathway, could promote trophoblast cell invasion during murine placentation. However, mechanism of Dkk-1 action on cell migration was not clear. The objective of this study was to further evaluate the effect of Dkk-1 on cell m...
متن کاملRole of nitric oxide in shock: the large animal perspective.
Excessive nitric oxide (NO) formation plays important roles in the pathogenesis of shock and multiple organ failure in sepsis and acute lung injury (ALI). Evidence from studies in large animal models of shock provide further insight into the role of NO and the varying nitric oxide synthase (NOS) isoforms. Nonselective NOS inhibition in sepsis models reversed sepsis-induced derangements in hemod...
متن کاملNon-prostaglandin eicosanoids in fever and anapyrexia.
Until recently, studies on the role of the metabolites of arachidonic acid (AA), eicosanoids in fever have primarily focused on prostaglandins, prostaglandin E2 (PGE2) in particular, derived from the pathway related to cyclooxygenases (COX). COX exists in two known isoforms; a constitutive COX-1, and COX-2, which is inducible upon the action of pyrogens. Data accumulated in our laboratories sug...
متن کاملThe biological evaluation of ADMA/SDMA and eNOS in patients with ACHF.
The aim of this study was to investigate the effects of acute pharmacological treatment on the plasma levels of l-arginine, asymmetrical dimethylarginine (ADMA), and symmetrical dimethylarginine (SDMA). We also investigated the related effects on endothelial nitric oxide synthase (eNOS) expression and activity and cytochrome c oxidase activity in the primary blood mononuclear cells (PBMCs) isol...
