Abstract
It has been established that blood element homeostasis is related to gliomagenesis which increases the attractiveness of the analysis of its components as a promising preoperative mediated characteristics of the molecular genetic profile of gliomas. The aim of this work is to analyze the relationship between mineral metabolism parameters and immunohistochemical characteristics of glial tumors and evaluate the clinical significance of blood element homeostasis analysis for preoperative assessment of the molecular profile of gliomas. The levels of cancer specific markers MGMT, Ki-67, p-53, IDH1 were determined immunohistochemically using the corresponding antibody clones. Micronutrient levels were analyzed by inductively coupled plasma atomic emission spectrometry recalculating the results per 1 g of protein which was determined by the Lowry method. The data on cancer-specific marker levels obtained in primary brain tumors (20) and in blood plasma of gliomas patients (20) and practically healthy subjects (5) were compared using a number of statistical programs. We found significant differences in the levels of sodium, potassium, zinc and copper depending on the value of the mitotic index Ki-67 and IDH1 isocitrate dehydrogenase gene mutation. For the first time, a significant correlation showing the consistency between the level of glial tumor cancer-specific markers and blood mineral metabolism was observed. The revealed correlations provide new insights into understanding of gliomagenesis mechanisms and can be used as a predictive preoperative assessment of molecular genetic markers of gliomas.
