Mitochondrial dynamics: A promising tool for personalized TNBC management

Area of Science:

• Oncology
• Molecular Biology
• Metabolic Research

Background:

• Triple-negative breast cancer (TNBC) is an aggressive subtype with poor prognosis due to limited targeted therapies.
• Mitochondrial dysfunction significantly contributes to TNBC growth, metastasis, and chemoresistance.
• Dysregulated mitochondrial dynamics and altered energetics provide metabolic advantages for TNBC survival.

Purpose of the Study:

• To review recent advancements in understanding mitochondrial dynamics and energetics in TNBC.
• To explore the molecular mechanisms behind mitochondrial dysregulation in TNBC.
• To discuss the therapeutic potential of targeting mitochondrial function for TNBC management.

Main Methods:

• Literature review of studies on mitochondrial dynamics and energetics in TNBC.
• Analysis of molecular mechanisms underlying mitochondrial dysfunction in TNBC.
• Evaluation of emerging therapeutic strategies targeting mitochondrial pathways.

Main Results:

• Mitochondrial dynamics inhibitors (e.g., Mdivi-1) restore homeostasis and induce apoptosis.
• Energetics inhibitors (e.g., 2DG) disrupt metabolic pathways, reducing TNBC growth.
• Targeting mitochondrial vulnerabilities presents promising avenues for TNBC treatment.

Conclusions:

• Mitochondrial dysfunction is a key driver of TNBC aggressiveness and chemoresistance.
• Targeting mitochondrial dynamics and energetics shows therapeutic potential for TNBC.
• Personalized strategies focused on mitochondrial function could improve TNBC clinical management.
