Peptidyl transferase center activity observed in single ribosomes

Journal of Molecular Biology, 1999
We demonstrate the functional activity of single ribosomal complexes, opening the way for detailed studies of the trajectories of protein synthesis. Our approach employs a single-molecule detection system, capable of picoseconds to minutes resolution, to observe a growing peptide labeled at its N terminus with the fluorophore tetramethylrhodamine (TMR).

Biomarkers for the estimation of isoproterenol‐induced myocardial infarction: A review of key parameters

Journal of Intelligent Medicine, Volume 3, Issue 1, Page 47-68, March 2026.
Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory ...

Treg cells retain stable lineage commitment during pregnancy in mice after late gestation inflammatory challenge

Immunology &Cell Biology, Volume 104, Issue 3, Page 276-311, March 2026.
In this study, we used Foxp3‐fatemapping mice to examine the cell lineage stability of Treg cells in pregnancy. Ex‐Foxp3 cells were identified in gestational tissues. However, Treg cells retained lineage stability with no increased ex‐Foxp3 generation, regardless of inflammatory challenges that induce preterm birth.

Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

New Phytologist, Volume 249, Issue 5, Page 2515-2530, March 2026.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

Deciphering mRNA Translation During Sperm Capacitation: A New Frontier in Fertility Research

Molecular Reproduction and Development, Volume 93, Issue 2, February 2026.
ABSTRACT Male infertility accounts for approximately 50% of infertility cases, with nearly 30% remaining unexplained after standard evaluations. This highlights the need for a better understanding of sperm function to advance diagnostic and therapeutic strategies. Sperm were long considered translationally quiescent; however, emerging evidence suggests

Transforming Fragile Hydrogel Chips Into Standardized Cartridges via Contact Line Pinning for Robust Microfluidics

Small, Volume 22, Issue 11, 20 February 2026.
Hydrogel‐based microfluidic chips revolutionize drug delivery, tissue engineering, and biosensing, yet face challenges due to fragility and connection difficulty. This study introduces a novel cartridge design that enhances usability through a hydrogel–plastic hybrid design and a contactless connection method.

Genome‐Wide Association Study and RNA Sequencing Identify Candidate Genes Regulating Nitrogen Use Efficiency and Associated Traits in Sorghum (Sorghum bicolor (L.) Moench)

Food and Energy Security, Volume 15, Issue 1, January/February 2026.
ABSTRACT Sorghum (Sorghum bicolor L. Moench) is a resilient cereal crop with remarkable adaptability to diverse environments. Nitrogen use efficiency (NUE) is critical for improving sorghum yields, resource utilization, livelihood security, and environmental sustainability of the target ecologies.

RNA aptamers to the peptidyl transferase inhibitor chloramphenicol

Chemistry & Biology, 1997
The problem of how macromolecules adopt specific shapes to recognize small molecules in their environment is readily addressed through in vitro selections (the SELEX protocol). RNA-antibiotic interactions are particularly attractive systems for study because they provide an opportunity to expand our understanding of molecular recognition by RNA and to ...

Deep Learning Can Predict the Overall Survival of Cervical Cancer Based on Histopathological Image, Gene Mutation and Clinical Information

IET Systems Biology, Volume 20, Issue 1, January/December 2026.
This study aims to develop a novel prediction model for the overall survival of patients with cervical cancer by incorporating a comprehensive range of data, including pathology images, clinical data and molecular data. The model was trained using data from The Cancer Genome Atlas (TCGA) and subsequently validated using a dataset from Peking Union ...

Protein engineering strategies to optimise recombinant product synthesis and accumulation in Nicotiana benthamiana

Plant Biotechnology Journal, Volume 24, Issue 1, Page 31-43, January 2026.
Summary In plant molecular farming, recombinant products include traditional protein targets, such as antibodies, antigens, and enzymes, but also increasingly refers to high‐value peptides, and small molecules produced by heterologous enzymatic pathways.
