SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

open access: yesCell Proliferation, EarlyView.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...

Laser-UV-microirradiation of interphase nuclei and posttreatment with caffeine: a new approach to establish the arrangement of interphase chromosomes [PDF]

open access: yes, 1976
Laser UV microirradiation of Chinese hamster interphase cells combined with caffeine post-treatment produced different patterns of chromosome damage in mitosis following irradiation of a small area of the nucleus that may be classified in three ...

A Water‐Saving Drought Survival Phenotype in a Wheat TILLING Mutant Involves Survival‐Biased Metabolic and Phosphorylation Reprogramming

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Drought tolerance in crops often involves trade‐offs between water conservation, growth and reproduction. Understanding how water‐saving strategies are implemented at physiological and metabolic levels remains critical for improving crop performance under water‐limited conditions.

A study of sister chromatid exchange in patients with dental amalgam restorations

open access: yesIndian Journal of Dental Research, 2014
Study Background: Dental amalgam is still widely used as a restorative material in developing countries due to its low cost and ease of manipulation. The health risks associated with the components of this restorative material has always been a matter of

ID3 deficiency alters chromatin accessibility at DSB sites and enhances vulnerability to HDAC inhibition

open access: yesInternational Journal of Cancer, Volume 158, Issue 12, Page 3173-3186, 15 June 2026.
What's new? Errors in DNA double‐strand break (DSB) repair can lead to mutations, chromosomal instability, and ultimately cancer. Inhibitor of DNA‐binding 3 (ID3), a transcriptional repressor, is crucial to promoting DSB repair and helping maintain genome stability. Here, the authors investigated ID3 regulation of DNA repair via chromatin accessibility

The genoprotective activity of resveratrol on permethrin-induced genotoxic damage in cultured human lymphocytes

open access: yesBrazilian Archives of Biology and Technology, 2013
The aim of this work was to investigate the genetic effects of resveratrol (RSV) at concentrations of 10, 15, 25, 40, 75 and 100 µM and its activities on the genotoxicity induced by the permethrin (PM) (200 µM).

Chromosome segregation in a minimal bacterial cell driven by SMC protein complexes

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Minimal bacterial cells such as JCVI‐Syn3A provide a powerful system for uncovering the essential mechanisms of chromosome organization and segregation. Lacking canonical systems such as Min and ParABS, JCVI‐Syn3A relies primarily on structural maintenance of chromosomes (SMC) protein complexes for partitioning.

Caenorhabditis elegans RMI2 functional homolog-2 (RMIF-2) and RMI1 (RMH-1) have both overlapping and distinct meiotic functions within the BTR complex.

open access: yesPLoS Genetics, 2021
Homologous recombination is a high-fidelity repair pathway for DNA double-strand breaks employed during both mitotic and meiotic cell divisions. Such repair can lead to genetic exchange, originating from crossover (CO) generation.
