Human embryonic stem cells are capable of executing G1/S checkpoint activation

T Bárta, V Vinarský, Z Holubcová, D Doležalová… - Stem Cells, 2010 - academic.oup.com
Embryonic stem cells progress very rapidly through the cell cycle, allowing limited time for cell
cycle regulatory circuits that typically function in somatic cells. Mechanisms that inhibit cell …

RNF43 inhibits WNT5A-driven signaling and suppresses melanoma invasion and resistance to the targeted therapy

…, T Gybeľ, K Kaiser, L Demková, L Kučerová, T Bárta… - Elife, 2021 - elifesciences.org
RNF43 is an E3 ubiquitin ligase and known negative regulator of WNT/β-catenin signaling.
We demonstrate that RNF43 is also a regulator of noncanonical WNT5A-induced signaling in …

Human embryonic stem cells suffer from centrosomal amplification

…, M Sedláčková, V Vinarský, D Doležalová, T Bárta… - Stem …, 2011 - academic.oup.com
Propagation of human embryonic stem cells (hESCs) in culture tends to alter karyotype,
potentially limiting the prospective use of these cells in patients. The chromosomal instability of …

Every ordinary differential equation with a strict Lyapunov function is a gradient system

T Bárta, R Chill, E Fašangová - Monatshefte für Mathematik, 2012 - Springer
We explain and prove the statement from the title. This allows us to formulate a new type of
gradient inequality and to obtain a new stabilization result for gradient-like ordinary …

Conducting composite films based on chitosan or sodium hyaluronate. Properties and cytocompatibility with human induced pluripotent stem cells

…, M Trchová, A Minařík, J Vajďák, T Bárta… - Carbohydrate …, 2021 - Elsevier
Novel composite films combining biocompatible polysaccharides with conducting polyaniline
(PANI) were prepared via the in-situ polymerization of aniline hydrochloride in the …

MicroRNAs Regulate p21Waf1/Cip1 Protein Expression and the DNA Damage Response in Human Embryonic Stem Cells

D Dolezalova, M Mraz, T Barta, K Plevova… - Stem …, 2012 - academic.oup.com
Studies of human embryonic stem cells (hESCs) commonly describe the nonfunctional p53-p21
axis of the G1/S checkpoint pathway with subsequent relevance for cell cycle regulation …

[HTML][HTML] Prenylated Flavonoids from Morus alba L. Cause Inhibition of G1/S Transition in THP-1 Human Leukemia Cells and Prevent the Lipopolysaccharide-Induced …

P Kollar, T Bárta, J Hošek, K Souček… - Evidence-Based …, 2013 - hindawi.com

P Kollár, T Bárta, V Závalová… - British Journal of …, 2011 - Wiley Online Library
BACKGROUND AND PURPOSE Paulownia tomentosa is a rich source of geranylated
flavanones, some of which we have previously shown to have cytotoxic activity. To identify …

Decrease in abundance of apurinic/apyrimidinic endonuclease causes failure of base excision repair in culture-adapted human embryonic stem cells

…, Z Dobšáková, L Eiselleová, K Matulka, T Bárta… - Stem Cells, 2013 - academic.oup.com
The inevitable accumulation of chromosomal abnormalities in human embryonic stem cells (hESCs)
during in vitro expansion represents a considerable obstacle for cell replacement …
