The Genetic Basis of Color Polymorphism in the Orb‐Web Spider Gasteracantha cancriformis
Ecology and Evolution, Volume 16, Issue 3, March 2026.This study investigates the genetic basis of coloration in the polymorphic spider Gasteracantha cancriformis using RNA‐seq data from different female color morphs. We assembled a reference transcriptome and identified differentially expressed genes associated with known pigmentation pathways, including carotenoids, melanin, ommochromes, and pteridines.

Structural basis for human mitochondrial tRNA maturation
Nature CommunicationsThe human mitochondrial genome is transcribed into two RNAs, containing mRNAs, rRNAs and tRNAs, all dedicated to produce essential proteins of the respiratory chain. The precise excision of tRNAs by the mitochondrial endoribonucleases (mt-RNase), P and Z,

Type 2 Diabetes From the Perspective of Telomere Biology
Endocrinology, Diabetes &Metabolism, Volume 9, Issue 2, March 2026.This graphical abstract illustrates the bidirectional relationship between the telomere/telomerase system and T2DM: telomere attrition contributes to pancreatic β‐cell dysfunction and insulin resistance through mechanisms such as oxidative stress and apoptosis, while T2DM‐related hyperglycemia and chronic inflammation further exacerbate telomere damage.

The role of ribonucleases in regulating global mRNA levels in the model organism Thermus thermophilus HB8 [PDF]
, 2014 BACKGROUND: RNA metabolism, including RNA synthesis and RNA degradation, is one of the most conserved biological systems and has been intensively studied; however, the degradation network of ribonucleases (RNases) and RNA substrates is not fully ...

Coupling immunity and programmed cell suicide in prokaryotes: Life-or-death choices [PDF]
, 2017 Host-pathogen arms race is a universal, central aspect of the evolution of life. Most organisms evolved several distinct yet interacting strategies of anti-pathogen defense including resistance to parasite invasion, innate and adaptive immunity, and ...

RNA/aTNA chimeras: RNAi effects and nucleases resistance of single and double stranded RNAs [PDF]
, 2014 The RNA interference pathway (RNAi) is a specific and powerful biological process, triggered by small non-coding RNA molecules and involved in gene expression regulation. In this work, we explored the possibility of increasing the biological stability of

YoeB-ribosome structure: a canonical RNase that requires the ribosome for its specific activity [PDF]
, 2017 As a typical endoribonuclease, YoeB mediates cellular adaptation in diverse bacteria by degrading mRNAs on its activation. Although the catalytic core of YoeB is thought to be identical to well-studied nucleases, this enzyme specifically targets mRNA ...

The endoribonuclease YbeY is linked to proper cellular morphology and virulence in 2 Brucella abortus [PDF]
, 2018 The endoribonuclease YbeY is one of the most well conserved proteins across the kingdoms of life. In the present study, we demonstrate that YbeY in Brucella abortus is linked to a variety of important activities, including proper cellular morphology ...
