Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling

Angewandte Chemie International Edition, Volume 65, Issue 23, 1 June 2026.
Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

Stability and Expression of Selected miRNAs, circRNAs, and rRNAs in Swiss Albino Mice Tissues to Preditc Port-Mortem Interval

Brazilian Journal of Forensic Sciences, Medical Law and Bioethics
In forensics, post-mortem interval (PMI) estimation is essential. Researchers have devised various approaches to accurately determine PMI, consequently, ribonucleic acid (RNA) molecules could be useful PMI estimation tool.

Chromosomal diversification in ribosomal DNA sites in Ancistrus Kner, 1854 (Loricariidae, Ancistrini) from three hydrographic basins of Mato Grosso, Brazil

Comparative Cytogenetics, 2011
Populations of seven Ancistrus species were analyzed from streams and rivers of three hydrographic Brazilian basins. All populations showed different diploid numbers (2n), fundamental numbers (FNs), and karyotypes.

Ribosomal Proteins in Cell Biology and Cancer

MedComm – Oncology, Volume 5, Issue 2, June 2026.
The functions of ribosomal proteins (RPs) extend beyond the conventional translation process, as they also regulate gene expression, stress responses, and disease progression. Dysregulation of RPs contributes to the onset and progression of various diseases, including cancer and ribosomopathies, underscoring their dual role as critical disease ...

Highly heterozygous Citrus changshan‐huyou Y. B. Chang originated from ancient hybridization between mandarin and pummelo and displayed distinct tissue‐specific allelic imbalance

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract The genus Citrus is characterized by a reticulate evolutionary history with frequent hybridization, making it an intriguing subject for genome evolution investigation. Citrus changshan‐huyou Y. B. Chang (Huyou) is a unique landrace first discovered in Zhejiang Province, China, with premium fruit quality.

Interplay of 'induced fit' and preorganization in the ligand induced folding of the aptamer domain of the guanine binding riboswitch

, 2006
Riboswitches are highly structured elements in the 50-untranslated regions (50-UTRs) of messenger RNA that control gene expression by specifically binding to small metabolite molecules. They consist of an aptamer domain responsible for ligand binding and
