Inactivation of CDK12 Enhances Mitochondrial Efficiency to Suppress DNA Damage

Journal of Cellular and Molecular Medicine, Volume 30, Issue 7, April 2026.
ABSTRACT Inactivation of cyclin‐dependent kinase 12 (CDK12) characterizes a subset of prostate cancers but it is not understood how cells adapt to declining activity of this major transcription elongation kinase. To probe this response, we developed a cell line resistant to an inhibitor targeting CDK12 and its paralog, CDK13.

MCM8-9 complex promotes resection of double-strand break ends by MRE11-RAD50-NBS1 complex. [PDF]

, 2015
MCM8-9 complex is required for homologous recombination (HR)-mediated repair of double-strand breaks (DSBs). Here we report that MCM8-9 is required for DNA resection by MRN (MRE11-RAD50-NBS1) at DSBs to generate ssDNA.

Stabilisation of Tomato Yellow Leaf Curl China Virus Infectious Clones Through Micro‐Homology Mediated End Joining

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2187-2200, April 2026.
ABSTRACT Tomato yellow leaf curl China virus (TYLCCNV) is a major agricultural pathogen and primary model for circular single‐stranded DNA (cssDNA) virus studies. The infectious clones of TYLCCNV and other cssDNA viruses are usually constructed as two tandem copies of the small viral genomes in Agrobacterium‐mediated T‐DNA vectors.

Glu-108 in Saccharomyces cerevisiae Rad51 Is Critical for DNA Damage-Induced Nuclear Function

mSphere, 2019
DNA damage-induced Rad51 focus formation is the hallmark of homologous recombination-mediated DNA repair. Earlier, we reported that Rad51 physically interacts with Hsp90, and under the condition of Hsp90 inhibition, it undergoes proteasomal degradation ...

UBR2 of the N-end rule pathway is required for chromosome stability via histone ubiquitylation in spermatocytes and somatic cells [PDF]

, 2012
The N-end rule pathway is a proteolytic system in which its recognition components (N-recognins) recognize destabilizing N-terminal residues of short-lived proteins as an essential element of specific degrons, called N-degrons.

Olaparib for patients with tumors harboring alterations in homologous recombination repair genes: Results from the drug rediscovery protocol

International Journal of Cancer, Volume 158, Issue 6, Page 1617-1627, 15 March 2026.
What's new? PARP inhibitors are effective in patients with inactivating alterations in the BRCA1/2 genes across tumor types. However, the efficacy of PARP inhibitors in patients with other inactivated homologous recombination repair genes remains unclear. This knowledge gap and discrepancies in EMA/FDA approvals highlight the need for better biomarkers.

BRCA2 Coordinates the Activities of Cell-Cycle Kinases to Promote Genome Stability

Cell Reports, 2014
Numerous human genome instability syndromes, including cancer, are closely associated with events arising from malfunction of the essential recombinase Rad51. However, little is known about how Rad51 is dynamically regulated in human cells. Here, we show

Positive regulation of meiotic DNA double-strand break formation by activation of the DNA damage checkpoint kinase Mec1(ATR) [PDF]

, 2013
During meiosis, formation and repair of programmed DNA double-strand breaks (DSBs) create genetic exchange between homologous chromosomes-a process that is critical for reductional meiotic chromosome segregation and the production of genetically diverse ...
