Exploring the microRNA-mitochondrial nexus in hepatocellular carcinoma

Area of Science:

• Oncology
• Molecular Biology
• Mitochondrial Biology

Background:

• MicroRNAs (miRNAs) exhibit dual roles in hepatocellular carcinoma (HCC) progression and suppression.
• Mitochondria are critical for cellular processes central to HCC, including energy production and apoptosis.
• The interplay between miRNAs and mitochondrial function is vital for understanding HCC pathogenesis.

Purpose of the Study:

• To comprehensively review the multifaceted roles of miRNAs in modulating mitochondrial function in HCC.
• To explore the impact of miRNAs on mitochondrial biogenesis, dynamics, apoptosis, and key metabolic pathways.
• To investigate the intricate relationship between miRNAs, mitochondrial function, mitophagy, and ferroptosis in HCC.

Main Methods:

• Literature review of studies investigating microRNA and mitochondrial interactions in hepatocellular carcinoma.
• Analysis of miRNA roles in regulating mitochondrial biogenesis, dynamics, and apoptosis.
• Examination of miRNA influence on cellular metabolism, oxidative stress, mitophagy, and ferroptosis.

Main Results:

• MiRNAs significantly regulate mitochondrial biogenesis, dynamics, and apoptosis in HCC.
• MiRNAs impact critical metabolic pathways, including energy and fatty acid metabolism, and oxidative stress.
• The microRNA-mitochondrial axis influences mitophagy and ferroptosis, key processes in HCC.

Conclusions:

• MiRNAs are pivotal regulators of mitochondrial function with a dual role in HCC.
• Understanding the microRNA-mitochondrial axis provides insights into HCC progression.
• This axis presents potential novel diagnostic and therapeutic targets for hepatocellular carcinoma.
