ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

20th Anniversary of human‐induced pluripotent stem cells and the role of microscopy

Journal of Microscopy, EarlyView.
Abstract It has been 20 years since the pioneering work of Shinya Yamanaka and Kazutoshi Takahashi at Kyoto University led to the first successful generation of induced pluripotent stem cells (iPSCs) from mouse embryonic and adult fibroblast cells. iPSCs have the capacity to differentiate into any type of cell in the human body, and as such, they have ...

A multi‐omics investigation of sarcopenia and frailty: Integrating genomic, epigenomic and telomere length data

Experimental Physiology, EarlyView.
Abstract Sarcopenia and frailty are complex geriatric syndromes influenced by a combination of genetic and environmental factors. Recent studies suggest that specific genetic variants, DNA methylation patterns and shortened telomeres are associated with age‐related diseases and might contribute to the development of both sarcopenia and frailty. In this

Senolytics and exercise: Dual modalities for rejuvenating muscle

The Journal of Physiology, EarlyView.
Abstract figure legend The role of senolytics on the heart and skeletal muscle. Senescent cell burden increases with ageing, disuse and disease. The senolytics dasatinib+quercetin (D+Q), navitoclax and fisetin, as well as exercise, eliminate senescent cells, reducing senescent cell burden and their senescence‐associated secretory phenotype (SASP ...

Heterochromatin structure and organization.

Heterochromatin comprises a highly condensed string of canonical and H2A.Z nucleosomes surrounded by K9 and K27 trimethyl H3 histones as well as the HP1α heterochromatin protein.

Technologies for engineering repetitive DNA

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Repetitive DNA, a fundamental architectural element of genomes, is widespread across organisms and comprises about 54% of the human genome. With advances in long‐read sequencing and bioinformatics approaches, highly repetitive sequences can now be characterized in depth.

Differentiating the Clinical and Variant Spectrum of Hardikar Syndrome From Other MED12 ‐Related Developmental Disorders

American Journal of Medical Genetics Part A, Volume 200, Issue 7, Page 1619-1650, July 2026.
ABSTRACT The rare X‐linked female‐restricted Hardikar syndrome (HDKR, OMIM # 301068) is characterized by multiple congenital anomalies including orofacial clefts, gastrointestinal, genitourinary, and cardiac anomalies, but cognitive and neurobehavioral development is rarely impaired.

The nuclear poly(A)-binding protein Pab2/PABPN1 promotes heterochromatin assembly through the formation of Pab2 nuclear condensates.

PLoS Genetics
The assembly of constitutive heterochromatin is a prerequisite for maintaining genome stability. However, the mechanism of heterochromatin formation has yet to be completely understood.

Epigenetic‐Based Evidence for Distinct Effects of Age, Sex, and Experience in Developmental Critical Period Learning

Developmental Neurobiology, Volume 86, Issue 3, July 2026.
ABSTRACT Although much is known about the encoding of experience, how the brain organizes neural circuits capable of learning and memory formation is largely unstudied. Canonical critical periods emerge from a convergence of maturation‐ and experience‐dependent processes.

Genome‐wide analysis of DNA methyltransferases in a model extremophyte, Schrenkiella parvula: Transcriptional dynamics during development and under salt stress

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Classification of DMTs into 4 subfamilies: two METs, three CMTs, three DRMs, and one DNMT2. The cis‐elements are associated with stress‐response, hormonal regulation, light‐response, and development. RNA‐seq analysis revealed differential expression of DMTs under NaCl stress.
