tsRNA, cell death and disease: Connecting the dots

Area of Science:

• Molecular Biology
• Genetics
• Cell Biology

Background:

• Cell death is vital for physiological homeostasis and disease regulation.
• tRNA-derived small RNAs (tsRNAs) are emerging non-coding RNAs with significant roles in various cell death forms.
• Understanding tsRNA involvement in cell death and disease is a growing research area.

Purpose of the Study:

• To review the generation and classification of tsRNAs.
• To elucidate the roles of tsRNAs in diverse cell death pathways including ferroptosis, apoptosis, necroptosis, autophagy, and pyroptosis.
• To discuss the dysregulation of tsRNAs in neurological disorders, metabolic diseases, and cancer.

Main Methods:

• Literature review and synthesis of existing research on tsRNAs and cell death.
• Analysis of tsRNA generation and classification mechanisms.
• Examination of tsRNA dysregulation in various disease contexts.

Main Results:

• tsRNAs are implicated in multiple cell death modalities.
• Dysregulated tsRNA expression is observed in neurological disorders, metabolic diseases, and cancer.
• tsRNAs demonstrate potential as biomarkers and therapeutic targets.

Conclusions:

• tsRNAs play multifaceted roles in regulating cell death processes.
• Aberrant tsRNA expression is linked to significant human diseases.
• Further research into tsRNAs offers promising avenues for diagnostics and therapeutics.
