Summary

This review systematically covers tRNA-derived small RNAs (tsRNAs) as stress-responsive noncoding RNAs and discusses their roles as biomarkers and therapeutic targets across organ injuries including lung, liver, cardiac, neuronal, and skeletal muscle injuries.

tRNA-derived small RNAs (tsRNAs) are a novel class of small noncoding RNAs, precisely cleaved from tRNA, functioning as regulatory molecules. The topic of tsRNAs in injuries has not been extensively discussed, and studies on tsRNAs are entering a new era. Here, we provide a fresh perspective on this topic. We systematically reviewed the classification, generation, and biological functions of tsRNAs in response to stress, as well as their potential as biomarkers and therapeutic targets in various injuries, including lung injury, liver injury, renal injury, cardiac injury, neuronal injury, vascular injury, skeletal muscle injury, and skin injury. We also provided a fresh perspective on the association between stress-induced tsRNAs and organ injury from a clinical perspective.

Dynamic non-coding RNA biomarker reveals lung injury and repair induced by polystyrene nanoplastics

Researchers found that mice and lung organoids (lab-grown mini-organs) repeatedly exposed to polystyrene nanoplastics suffered lung tissue damage, impaired repair processes, and changes in non-coding RNA molecules that could serve as early warning biomarkers for nanoplastic-induced lung injury.

A study on the roles of long non-coding RNA and circular RNA in the pulmonary injuries induced by polystyrene microplastics

Researchers exposed rats to polystyrene microplastics through the airways and found evidence of lung tissue damage, including destroyed air sacs and inflammation. The study identified changes in the activity of long non-coding RNAs and circular RNAs, types of genetic regulators that may help explain how microplastics cause lung injury at the molecular level. These findings provide new insight into the biological mechanisms behind potential respiratory harm from inhaling microplastic particles.

A novel tiRNA-Glu-CTC induces nanoplastics accelerated vascular smooth muscle cell phenotypic switching and vascular injury through mitochondrial damage

Researchers discovered that nanoplastic exposure activates a specific small RNA molecule called tiRNA-Glu-CTC, which accelerates harmful changes in blood vessel smooth muscle cells. This molecular mechanism caused mitochondrial damage and promoted the kind of cell behavior associated with vascular injury and disease. The study identifies a new biological pathway through which nanoplastics may contribute to cardiovascular harm.
