Molecular Mechanisms of the Therapeutic Effect of Selenium Nanoparticles in Hepatocellular Carcinoma

Area of Science:

• Biochemistry
• Nanotechnology
• Oncology

Background:

• Hepatocellular carcinoma remains a leading cause of cancer death globally.
• Current treatments for hepatocellular carcinoma have limitations, necessitating novel therapeutic strategies.
• Understanding molecular mechanisms of novel agents is crucial for advancing cancer therapy.

Purpose of the Study:

• To review the molecular mechanisms underlying the cytotoxic effects of selenium nanoparticles on hepatocellular carcinoma cells.
• To consolidate recent findings on how selenium nanoparticles modulate signaling pathways and induce cell death in liver cancer.
• To highlight the role of specific selenoproteins in these processes.

Main Methods:

• Comprehensive literature search of recent studies on selenium nanoparticles and hepatocellular carcinoma.
• Analysis of molecular pathways, including endoplasmic reticulum stress and cell death signaling.
• Focus on the involvement of selenoproteins, glutathione peroxidases, and thioredoxin reductases.

Main Results:

• Selenium nanoparticles induce cytotoxicity in hepatocellular carcinoma cells through diverse molecular mechanisms.
• Regulation of key signaling pathways and induction of endoplasmic reticulum stress are implicated.
• Selenoproteins, glutathione peroxidases, and thioredoxin reductases play significant roles in mediating these effects.

Conclusions:

• Selenium nanoparticles represent a promising therapeutic avenue for hepatocellular carcinoma.
• Further research into their specific molecular targets and pathways is warranted.
• This review provides a foundational understanding for developing selenium nanoparticle-based liver cancer therapies.
