Huntington's disease (HD) is an incurable hereditary neurodegenerative disorder, which manifests itself as a loss of GABAergic medium spiny (GABA MS) neurons in the striatum and caused by expansion CAG repeat exon 1 huntingtin gene. There no cure for HD, existing pharmaceutical can only relieve its symptoms. Here, induced pluripotent stem cells were established from patients with low gene, then efficiently differentiated into GABA MS-like (GMSLNs) under defined culture conditions. The...

Abstract Terahertz (THz) radiation was proposed recently for use in various applications, including medical imaging and security scanners. However, there are concerns regarding the possible biological effects of non-ionising electromagnetic THz range on cells. Human embryonic stem cells (hESCs) extremely sensitive to environmental stimuli we therefore utilised this cell model investigate non-thermal irradiation. We studied DNA damage transcriptome responses hESCs exposed narrow-band (2.3...

Reprogramming of a limited number human cell types has been achieved through ectopic expression four transcription factors to yield induced pluripotent stem (iPS) cells that closely resemble embryonic (ESCs). Here, we determined functional and epigenetic properties iPS generated from umbilical vein endothelial (HUVEC) by conventional method direct reprogramming. Retroviral overexpression resets HUVEC the pluripotency. Human cell-derived (endo-iPS) were similar ESCs in morphology, gene...

Huntington's disease (HD) is a severe autosomal-dominant neurodegenerative disorder caused by mutation within gene, encoding huntingtin protein. Here we have used the induced pluripotent stem cell technology to produce patient-specific terminally differentiated GABA-ergic medium spiny neurons modeling juvenile form of HD (HD76). We shown that calcium signaling dramatically disturbed in HD76 neurons, specifically demonstrating higher levels store-operated and voltage-gated uptakes. However,...

Abstract Background Dozens of transplants generated from pluripotent stem cells are currently in clinical trials. The creation patient-specific iPSCs makes personalized therapy possible due to their main advantage immunotolerance. However, some reports have claimed recently that aberrant gene expression followed by proteome alterations and neoantigen formation can result recognition autologous T-cells. Meanwhile, the possibility NK-cell activation has not been previously considered. This...

<i>Background and aims:</i> Cosmic radiation is one of the main hazards for manned space exploration. Uncertainty in risk estimates crews long-term missions are very high, direct biological measurements necessary. We measured chromosomal aberrations peripheral blood lymphocytes from 33 cosmonauts involved during past 11 years. <i>Methods:</i> Blood were stimulated to grow vitro harvested at their first mitosis. Slides either stained with Giemsa stain dicentrics...

Abstract What strategies do bacteria employ for adaptation to their hosts and are these different varied hosts? To date, many studies on the interaction of bacterium its host have been published. However, global changes in bacterial cell process invasion persistence, remain poorly understood. In this study, we demonstrated phase transition avian pathogen Mycoplasma gallisepticum upon various types eukaryotic cells (human, chicken, mouse) which was stable during several passages after...

DNA-intercalated motifs (iMs) are facile scaffolds for the design of various pH-responsive nanomachines, including biocompatible pH sensors. First, DNA sensors relied on complex intermolecular scaffolds. Here, we used a simple unimolecular dual-labeled iM scaffold and minimized it by replacing redundant loop nucleosides with abasic or alkyl linkers. These modifications improved thermal stability increased rates its pH-induced conformational transitions. The best effects were obtained upon...

G-quadruplex (G4) sites in the human genome frequently colocalize with CCCTC-binding factor (CTCF)-bound CpG islands (CGIs). We aimed to clarify role of G4s CTCF positioning. Molecular modeling data suggested direct interactions, so we performed vitro binding assays quadruplex-forming sequences from CGIs genome. bound Kd values similar that control duplex, while respective i-motifs exhibited no affinity for CTCF. Using ChIP-qPCR assays, showed G4-stabilizing ligands enhance occupancy at a...

About 15% of patients with parkinsonism have a hereditary form Parkinson’s disease (PD). Studies on the early stages PD pathogenesis are challenging due to lack relevant models. The most promising ones models based dopaminergic neurons (DAns) differentiated from induced pluripotent stem cells (iPSCs) forms PD. This work describes highly efficient 2D protocol for obtaining DAns iPSCs. is rather simple, comparable in efficiency previously published protocols, and does not require viral...

The pluripotency of newly developed human induced pluripotent stem cells (iPSCs) is usually characterized by physiological parameters; i.e., their ability to maintain the undifferentiated state and differentiate into derivatives 3 germ layers. Nevertheless, a molecular comparison physiologically normal iPSCs "gold standard" pluripotency, embryonic (ESCs), often reveals set genes with different expression and/or methylation patterns in ESCs.

A bstract Background Prostate adenocarcinoma (PRAD) is the second leading cause of cancer-related deaths in men. High variability DNA methylation and a high rate large genomic rearrangements are often observed PRAD. Results To investigate reasons for such variance, we integrated methylation, RNA-seq, copy number alterations datasets from The Cancer Genome Atlas (TCGA), focusing on PRAD, employed weighted gene co-expression network analysis (WGCNA). Our results show that only single cluster...
