Bente Benedict et al.
Developmental cell, 52(6), 683-698 (2020-02-23)
Premature loss of sister chromatid cohesion at metaphase is a diagnostic marker for different cohesinopathies. Here, we report that metaphase spreads of many cancer cell lines also show premature loss of sister chromatid cohesion. Cohesion loss occurs independently of mutations...

DNA double-strand breaks (DSBs) are deleterious and tumorigenic but could also be essential for DNA-based processes. Yet the landscape of physiological DSBs and their role and repair are still elusive. Here, we mapped DSBs at high resolution in cancer and...

Telomeres are essential for genome stability. Oxidative stress caused by excess reactive oxygen species (ROS) accelerates telomere shortening. Although telomeres are hypersensitive to ROS-mediated 8-oxoguanine (8-oxoG) formation, the biological effect of this common lesion at telomeres is poorly understood because...

The primary function of the UBE2T ubiquitin conjugase is in the monoubiquitination of the FANCI-FANCD2 heterodimer, a central step in the Fanconi anemia (FA) pathway. Genetic inactivation of UBE2T is responsible for the phenotypes of FANCT patients; however, a FANCT...
An engineered thermal-shift screen reveals specific lipid preferences of eukaryotic and prokaryotic membrane proteins

X Chen et al.
Oncogene, 35(1), 22-34 (2015-04-22)
Fanconi anemia (FA) is a genetic disease of bone marrow failure, cancer susceptibility, and sensitivity to DNA crosslinking agents. FANCD2, the central protein of the FA pathway, is monoubiquitinated upon DNA damage, such as crosslinkers and replication blockers such as...
Zuzana Nascakova et al.
International journal of molecular sciences, 22(7) (2021-05-01)
R-loops are three-stranded structures generated by annealing of nascent transcripts to the template DNA strand, leaving the non-template DNA strand exposed as a single-stranded loop. Although R-loops play important roles in physiological processes such as regulation of gene expression, mitochondrial...

Reproduction (Cambridge, England), 157(3), 223-234 (2019-03-01)
Homologous recombination (HR) plays a critical role in facilitating replication fork progression when the polymerase complex encounters a blocking DNA lesion, and it also serves as the primary mechanism for error-free DNA repair of double-stranded breaks. DNA repair protein RAD51...
RAD51 maintains chromosome integrity and mitochondrial distribution during porcine oocyte maturation in vitro

Local intravitreal or intra-arterial chemotherapy has improved therapeutic success for the pediatric cancer retinoblastoma (RB), but toxicity remains a major caveat. RB initiates primarily with RB1 loss or, rarely, MYCN amplification, but the critical downstream networks are incompletely understood. We...
Inhibition of DNA repair protein RAD51 affects porcine preimplantation embryo development
Jin ZL, et al.
Reproduction (Cambridge, England), 157(3) (2019)
A small-molecule inhibitor of RAD51 reduces homologous recombination and sensitizes multiple myeloma cells to doxorubicin
Alagpulinsa DA, et al.

The Journal of reproduction and development, 63(5), 489-496 (2017-08-02)
DNA repair protein RAD51 homolog 1 (RAD51) plays a central role in homologous recombination (HR) repair of DNA breaks. HR depends on the formation of a RAD51 recombinase filament that facilitates strand invasion. However, the role of RAD51 during porcine...

Under conditions of genotoxic stress, cancer cells strongly rely on efficient DNA repair to survive and proliferate. The human BRCA2 tumor suppressor protein is indispensable for the repair of DNA double-strand breaks by homologous recombination (HR) by virtue of its...

In checkpoint-deficient cells, DNA double-strand breaks (DSBs) are produced during replication by the structure-specific endonuclease MUS81. The mechanism underlying MUS81-dependent cleavage, and the effect on chromosome integrity and viability of checkpoint deficient cells is only partly understood, especially in human...
