Mitochondrial ribosomal proteins in metastasis and their potential use as prognostic and therapeutic targets

Area of Science:

• Cell Biology
• Molecular Oncology
• Biochemistry

Background:

• Mitochondria, the cell's powerhouse, rely on nuclear-encoded mitochondrial ribosomal proteins (MRPs).
• MRPs are crucial for mitochondrial functions including translation, transcription, and cell death regulation.
• Altered MRP expression is linked to cancer survival, progression, metastasis, and serves as a potential prognostic marker.

Purpose of the Study:

• To review the role of key MRPs as molecular drivers in various advanced cancer types.
• To explore the potential of MRPs as precision therapeutic targets in late-stage cancers.
• To identify opportunities for repurposing FDA/EMA-approved MRP-targeting therapies for cancer treatment.

Main Methods:

• Literature review of scientific articles and clinical trial data.
• Analysis of studies investigating MRP expression in different cancer types.
• Examination of existing therapies targeting MRPs for other diseases.

Main Results:

• MRPs play a central role in cell survival and progression in multiple advanced cancers.
• Evidence supports specific MRPs as molecular drivers of metastasis and disease advancement.
• Approved MRP-targeting therapies for other conditions present repurposing opportunities.

Conclusions:

• Key MRPs are significant molecular drivers in advanced and metastatic cancers.
• Repurposing existing MRP-targeting drugs is a promising strategy for late-stage cancer treatment.
• MRPs represent viable precision targets for novel oncological therapies.
