Crosstalk between chromatin structure, cohesin activity and transcription
(BMC (part of Springer Nature), 2019)
Background: A complex interplay between chromatin and topological machineries is critical for genome architec‑ ture and function. However, little is known about these reciprocal interactions, even for cohesin, despite its ...

The DNA damage response acts as a safeguardagainst harmful DNA–RNA hybrids ofdifferent origins
(EMBO Press, 2019-07-24)
Despite playing physiological roles in specific situations, DNA–RNA hybrids threat genome integrity. To investigate how cells do counteract spontaneous DNA–RNA hybrids, here we screen an siRNA library covering 240 human ...

Immunohistochemical assessment of Pax8 expression during pancreatic islet development and in human neuroendocrine tumors
(Springer Verlag, 2011)
The paired box transcription factor Pax8 is critical for development of the eye, thyroid gland as well as the urinary and reproductive organs. In adult, Pax8 overexpression is associated with kidney, ovarian and thyroid ...

Generation of a human iPS cell line from a patient with retinitis pigmentosa due to EYS mutation
(Elsevier, 2018-11-16)
Retinitis pigmentosa (RP) is an inherited retinal degenerative disease. Mutations in EYS have been associated with autosomal recessive RP. The human iPS cell line, CABi002-A, derived from peripheral blood mononuclear cells ...

What causes an RNA-DNA hybrid to compromise genome integrity?
(Elsevier, 2019)
Transcription is a source of genome instability that stimulates mutation and recombination. Part of the damage produced by transcription is mediated by R-loops, non-B DNA structures that normally form by the re-annealing ...

Manganese Redistribution by Calcium-stimulated Vesicle Trafficking Bypasses the Need for P-type ATPase Function
(American Society for Biochemistry and Molecular Biology, 2015)
Regulation of intracellular ion homeostasis is essential for eukaryotic cell physiology. An example is provided by loss of ATP2C1 function, which leads to skin ulceration, improper keratinocyte adhesion, and cancer formation ...

Late rDNA Condensation Ensures Timely Cdc14 Release and Coordination of Mitotic Exit Signaling with Nucleolar Segregation
(Elsevier, 2017)
The nucleolus plays a pivotal role in multiple key cellular processes. An illustrative example is the regulation of mitotic exit in Saccharomyces cerevisiae through the nucleolar sequestration of the Cdc14 phosphatase. The ...

miR-7 Modulates hESC Differentiation into Insulin-Producing Beta-like Cells and Contributes to Cell Maturation
(The American Society of Gene and Cell Therapy, 2018-09-07)
Human pluripotent stem cells retain the extraordinary capacity to differentiate into pancreatic beta cells. For this particular lineage, more effort is still required to stress the importance of developing an efficient, ...

Elongation Factor TFIIS Prevents Transcription Stress and R-Loop Accumulation to Maintain Genome Stability
(Elsevier, 2019)
Although correlations between RNA polymerase II (RNAPII) transcription stress, R-loops, and genome instability have been established, the mechanisms underlying these connections remain poorly understood. Here, we used a ...

Expression of TDRD9 in a subset of lung carcinomas by CpG island hypomethylation protects from DNA damage
(Impact Journals, 2018)
Tudor domain containing protein 9 (TDRD9) is a RNA helicase normally expressed in the germline, where it is involved in the biosynthesis of PIWI-interacting RNAs (piRNAs). Here, we show that TDRD9 is highly expressed in ...
