AIM To show the existence of a structural formative role of magnetic fields (MFs) with respect to biological objects by using our proposed model of an acupoint. METHODS We introduced a magnetised 10-100 μT metal rod (needle) into culture dishes with a negatively charged working surface and observed during 24 h how cells were arranged by MFs and by electrical fields (EFs) when attached. Rat an...

BACKGROUND Zfx is a zinc finger protein of the Zfy family, whose members are highly conserved in vertebrates. Zfx is a shared transcriptional regulator of both embryonic stem cells (ESC) and hematopoietic stem cells (HSC), which suggests a common genetic basis of self-renewal in embryonic and adult stem cells. The level of Zfx expression correlates with aggressiveness and severity in many cance...


 Purpose: To examine the role of miR-557 in pathogenesis and development glioblastoma (GBM) its potential regulatory mechanism.
 Methods: Dysregulation GBM cells was determined using quantitative (real-time) PCR (qPCR). Cell proliferative ability, migratory activity invasive ability were measured MTT colorimetric assay, wound healing assay Transwell chambers assay. The direct target ...

Nestin, a class VI intermediate filament protein, was originally described as a neuronal stem cell marker during central nervous system development. Nestin is expressed in gliomas, and its expression levels are higher in gliomas with high WHO histopathological classification grades than in those with low grades. In the present study, we examined whether nestin regulates the biological activitie...

a-Difluoromethylornithine (DFMO), an irreversible inhibitor of the polyamine biosynthetic enzyme ornithine decarboxylase, inhibits the growth of brain tumor cell lines and is undergoing clinical trials as a treatment for brain tumors. Platelet-derived growth factor (PDGF) is thought to regulate the growth and development of precursors of both normal and neoplastic astrocytic cells; calcium sign...
