Abstract
Xenon and cobalt are representatives of hypoxia-inducible factor (HIF) activators stimulating erythropoiesis and are prohibited by the World Anti-Doping Agency (WADA). The expression profiles of 84 microRNAs circulating in blood plasma and involved in the regulation of the HIF-1α transcription factor and its downstream signaling pathways were analyzed in volunteers before and after intake of cobalt (II) and xenon preparations using quantitative real-time PCR and certified miRCURY LNA miRNA Focus Panel (Qiagen) for analysis of microRNA expression profiles. Intake of cobalt aspartate increased the expression of hsa-miR-15b-5p, while inhalation of the Xe/O2 mixture significantly increased the plasma levels of hsa-miR-378a-3p and hsa-miR-491-5p. Thus, we for the first time revealed differential expression of microRNAs circulating in plasma in response to various HIF activators. Potential microRNA markers for identification of cobalt and xenon abuse for anti-doping control are proposed.
期刊介绍:
Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005.
World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells.
The Russian Volume Year is published in English from April.
