The Relationship of Agmatine Deficiency with the Lung Cancer

WOS: 000388274800006
The polyamines are essential for rapidly growing cells. Polyamines is synthesized by two reactions which begin from arginine. The aim of this study is to examine the serum levels of the enzymes located in the putrescine synthesis pathway and their relationship with lung cancer. In addition, the study also aim determine the oxidant-antioxidant status and the oxidative stress index. This study was performed on 36 lung cancer patients and 36 healthy controls. The arginase activity and the ornithine level were determined spectrophotometrically while the arginine decarboxylase, ornithine decarboxylase and agmatinase levels were determined by using Enzyme Linked Immunosorbent Assay (Elisa kit). The total antioxidant (TAS) and total oxidant status (TOS) were determined using a commercial kit auto analyser, oxidative stress index (OSI) was subsequently estimated. We observed an increase in ornithine decarboxylase, agmatinase and arginase levels in cancer patients (p< 0.05). however, no significant difference was observed between the two groups with regards to orithine and arginase decarboxylase levels (p> 0.05). In the patient group, the TAS values decreased (p< 0.05), while the TOS values increased (p< 0.05). In addition, the OSI values increased (p< 0.05). Reduced agmatine level can cause an increase in polyamine synthesis and cell proliferation. For this reason, lung cancer prognosis may have a relationship with the agmantine levels.
