Human trophoblast stem cells (hTSCs) can be derived from embryonic (hESCs) or induced somatic by OCT4, SOX2, KLF4 and MYC (OSKM). Here we explore whether the hTSC state independently of pluripotency, what are mechanisms underlying its acquisition. We identify GATA3, (GOKM) as a combination factors that generate functional hiTSCs fibroblasts. Transcriptomic analysis stable GOKM- OSKM-hiTSCs reveals 94 hTSC-specific genes aberrant specifically in OSKM-derived hiTSCs. Through...
Dravet syndrome (DRVT) is a rare form of neurodevelopmental disorder with high risk sudden unexpected death in epilepsy (SUDEP), caused mainly (>80% cases) by mutations the SCN1A gene, coding Nav1.1 protein (alfa-subunit voltage-sensitive sodium channel). Mutations are linked to heterogenous epileptic phenotypes various types, severity, and patient prognosis. Here we generated iPSC lines from fibroblasts obtained three individuals affected DRVT carrying distinct gene (nonsense mutation...
HAX-1 is a multi-functional protein that involved in the regulation of apoptosis, cell motility and calcium homeostasis. It also reported to bind RNA: it associates with structural motifs present 3' untranslated regions at least two transcripts, but functional significance this binding remains unknown. Although has been detected various cellular compartments, predominantly cytoplasmic. Our detailed localization studies isoforms revealed partial nuclear localization, extent which depends on...

In present study, influence small molecules representing epigenetic modulators (histone deacetylase inhibitor Trichostatin A DNA methyltransferase RG-108) on process reverting neural progenitors HUCB-NSC (Human Umbilical Cord Blood Neural Stem Cell) line to...
HAX-1, a multifunctional protein involved in the regulation of apoptosis, cell migration, and calcium homeostasis, binds 3′ untranslated region motifs specific transcripts. This suggests that HAX-1 plays role post-transcriptional regulation, at level mRNA stability/transport or translation. In this study, we analyze detail colocalization with processing bodies (P-bodies) its dependence on availability. Endogenous P-body markers DCP1 Rck/p54 were shown to colocalize endogenous but case...
In the context of cell therapy, epigenetic status core stemness transcription factor (STF) genes regulating proliferation/differentiation program is primary interest. Our results confirmed that in vitro differentiation umbilicalcord-blood-derived-neural-stem-cells (HUCB-NSC) coincides with progressive down-regulation Oct3/4 and Nanog gene expression. Consistently parallel repression transcription, a substantial increase mosaic cytosine methylation CpG dinucleotide was observed promoter...

SUMMARY Recent studies demonstrated that human trophoblast stem-like cells (hTS-like cells) can be derived from naïve embryonic stem or induced somatic by the pluripotency factors, OSKM. This raises two main questions; (i) whether TSCs (hiTSCs) generated independently to pluripotent state factors and (ii) what are mechanisms which hTSC is established during reprogramming. Here, we identify GATA3, OCT4, KLF4 MYC (GOKM) as a pluripotency-independent combination of generate stable functional...
