Int J Radiat Biol
. 2022 Nov;
99(5):760-768.
PMID: 36352506
Purpose: We studied the effects of computed tomography (CT) scan irradiation on proliferation and differentiation of human embryonic stem cells (hESCs). It was reported that hESC is extremely radiosensitive; exposure...

Radiat Res
. 2020 Mar;
193(5):460-470.
PMID: 32216708
Human embryonic brain development is highly sensitive to ionizing radiation. However, detailed information on the mechanisms of this sensitivity is not available due to limited experimental data. In this study,...

Int J Mol Sci
. 2019 Aug;
20(16).
PMID: 31405104
We studied the effect of radiation from computed tomography (CT) scans on differentiation of human embryonic stem cells (hESCs) into neuronal lineage. hESCs were divided into three radiation exposure groups:...

Mutat Res
. 2017 Aug;
803-805:22-25.
PMID: 28837838
We assessed single nucleotide variations (SNVs) between individual cells in two cancer cell lines; DU145, from brain metastasis of prostate tumor with deficient mismatch repair; and HT1080, a fibrosarcoma cell...

Sci Rep
. 2017 Mar;
7:43995.
PMID: 28266624
We studied the effect of ionizing radiation (IR) on continuous growth of seven hESC lines. Cells were exposed to 0, 0.2, or 1 Gy of X-rays, and the growth rates...

Int J Mol Sci
. 2016 Jan;
17(1).
PMID: 26729112
Chromatin structure affects the extent of DNA damage and repair. Thus, it has been shown that heterochromatin is more protective against DNA double strand breaks (DSB) formation by ionizing radiation...

Nguyen V, Panyutin I, Panyutin I, Neumann R
Stem Cells Int
. 2015 Dec;
2016:1346521.
PMID: 26709353
Ionizing radiation (IR) is a known mutagen that is widely employed for medical diagnostic and therapeutic purposes. To study the extent of genetic variations in DNA caused by IR, we...

Nucleic Acid Ther
. 2015 Feb;
25(2):78-84.
PMID: 25650982
Guanine (G)-rich DNA sequences can adopt four-stranded quadruplex conformations that may play a role in the regulation of genetic processes. To explore the possibility of targeted molecular recognition of DNA...

World J Stem Cells
. 2014 Nov;
6(5):598-605.
PMID: 25426256
Human pluripotent stem cells (hPSCs) represent heterogeneous populations, including induced pluripotent stem cells (iPSCs), endogenous plastic somatic cells, and embryonic stem cells (ESCs). Human ESCs are derived from the inner...

PMID: 25044379
Recent studies have shown that guanine-rich (G-rich) sequences with the potential to form quadruplexes might play a role in normal transcription as well as overexpression of oncogenes. Chemical tools that...
