eEF1G Orchestrates Translation to Ensure Meiotic Progression in Transcriptionally Quiescent Spermatocytes

Advanced Science, EarlyView.
eEF1G supports translation elongation of meiotic mRNAs in transcriptionally quiescent leptotene and zygotene spermatocytes. Its depletion in germ cells causes meiotic arrest at the zygotene stage, with defective homologous synapsis and unstable recombination intermediates.

Fission yeast Rad54 prevents intergenerational buildup of Rad51 aggregates in proliferating cells

Life Science Alliance
Live imaging of Rad51 revealed that rad54 mutant cells not only accumulate Rad51 but also transmit Rad51 aggregates to daughter cells, which likely causes intergenerational genome instability.

PFKFB4 Deubiquitination by USP10 Enhances Fumarate Metabolism to Orchestrate the KDM1A/Rad51 Axis and Confer Radioresistance in Lung Cancer

Advanced Science, EarlyView.
USP10 binds to and stabilizes PFKFB4, enhancing glycolytic ATP production, which activates the urea cycle and elevates fumarate. This inhibits histone demethylase KDM1A, leading to increased H3K4me1 enrichment at the Rad51 promoter and direct activation of Rad51 transcription, which confers lung cancer radioresistance. The PFKFB4 inhibitor 5MPN targets

Loss of CYLD on Chromosome 16q Impairs Homologous Recombination and Genomic Stability Through TIRR Degradation

Advanced Science, EarlyView.
Chromosome 16q loss drives genomic instability through disruption of the CYLD–TIRR–53BP1 axis. CYLD preserves homologous recombination by stabilizing TIRR and limiting 53BP1 accumulation at DNA double‐strand breaks. CYLD deficiency redirects repair toward error‐prone non‐homologous end joining, promotes mutational burden and homologous recombination ...

The Homozygous p.(Arg215Ter) Variant in XRCC2 Is Associated With Atypical Fanconi Anemia Without Major Hematological Abnormalities in Childhood

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Fanconi Anemia (FA) is the most frequent inherited bone marrow failure syndrome. A role for the XRCC2 gene in FA was suspected in 2012 and confirmed in 2016, but only two affected individuals have been described thus far, and no long‐term follow‐up is available.

RAD51AP1 is a versatile RAD51 modulator. [PDF]

Proc Natl Acad Sci U S A
RAD51AP1 is an emergent key factor in homologous recombination (HR), the major pathway for accurate repair of DNA double-strand breaks, and in alternative lengthening of telomeres (ALT). Depletion of RAD51AP1 diminishes HR and overexpression is common in cancer, where it is associated with malignancy.

Quantum‐Level Influences on Enzyme Reactions and Their Ripple Effects on Biological Phenomena

Advanced Physics Research, EarlyView.
Because living organisms are ultimately composed of atoms and molecules, quantum‐mechanical effects are expected to contribute to biological phenomena. Quantum biology seeks to elucidate life processes from a quantum‐mechanical perspective. This review discusses how quantum‐level effects, including quantum tunneling, may propagate from enzymatic proton‐

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

A novel small molecule RAD51 inactivator overcomes imatinib‐resistance in chronic myeloid leukaemia

EMBO Molecular Medicine, 2013
RAD51 recombinase activity plays a critical role for cancer cell proliferation and survival, and often contributes to drug‐resistance. Abnormally elevated RAD51 function and hyperactive homologous recombination (HR) rates have been found in a panel of ...

The epistatic relationship between BRCA2 and the other RAD51 mediators in homologous recombination. [PDF]

PLoS Genetics, 2011
RAD51 recombinase polymerizes at the site of double-strand breaks (DSBs) where it performs DSB repair. The loss of RAD51 causes extensive chromosomal breaks, leading to apoptosis.
