Dereplicative Combination of HPLC/DAD/MS and 2D NMR to Identify Lichexanthone Isomers in Lichen Extracts

Phytochemical Analysis, Volume 37, Issue 2, Page 330-343, March 2026.
ABSTRACT Introduction Lichexanthones are the major xanthones found in lichens. They present a high degree of isomerism, which makes their identification tedious. Xanthones are known to occur in lichens according to chemosyndromes, and these compounds act as chemotaxonomic markers.

DNA methylation meets lineage tracing: History, recent progress, and future directions

Quantitative Biology, Volume 14, Issue 1, March 2026.
Abstract Lineage tracing techniques have been developed rapidly in the past decades by employing new genetic engineering tools. However, due to their invasive nature, these are difficult to apply to humans. Although endogenous DNA mutations can be used for in vivo lineage tracing in humans, their extremely low mutation rate presents substantial ...

Epigenetic modifications regulate peg elongation and underground fruiting in peanut in response to environmental cues

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Epigenetic regulation plays a central role in coordinating peanut (Arachis hypogaea L.) fruit pegging, a unique developmental process in which fertilized ovaries transition from aerial growth to subterranean pod formation. This review synthesizes current evidence demonstrating that dynamic interactions among DNA methylation, histone ...

The mirage of DNA methylation in transcriptional regulation of plants

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract “Cytosine methylation plays an important role in the regulation of gene expression in plants.” Some iteration of this statement can be found in most papers centered on plant epigenetics and has become a widely accepted textbook claim. However, our generalized understanding of how DNA methylation exerts control over transcription is now ...

Ageing Through the Looking‐Glass: The Different Flavours of Clonal Haematopoiesis

Aging Cell, Volume 25, Issue 3, March 2026.
Different forms of CH share common germline and environmental risk factors and have overlapping prevalence and disease associations, suggesting common underlying ageing processes. We explore intersections of different forms of CH, clinical implications of these, and how this enhances our understanding of the biology of ageing.

Decreased Glucose Metabolism and Declined Chaperones Are Unique Features Required for the Survival of Senescent Fibroblasts and Pyruvate Dehydrogenase Is a Potent Senolytic Target

Aging Cell, Volume 25, Issue 3, March 2026.
By a global proteomic profiling of senescent human BJ fibroblasts induced by ionizing radiation, key cellular features required for the survival of senescent fibroblasts were revealed, and pyruvate dehydrogenase was demonstrated as a potent senolytic target for selectively eliminating senescent normal cells, particularly the therapy‐induced senescent ...
