Preclinical Models of Hepatocellular Carcinoma: Current Utility, Limitations, and Challenges

Area of Science:

• Oncology
• Hepatology
• Translational Research

Background:

• Hepatocellular carcinoma (HCC) is a leading cause of cancer death globally.
• Despite therapeutic advances, HCC remains a significant clinical challenge.
• Novel preclinical models are crucial for advancing liver cancer research.

Purpose of the Study:

• To review and discuss commonly used preclinical models for Hepatocellular Carcinoma (HCC).
• To evaluate the strengths and weaknesses of various HCC preclinical models.
• To highlight the role of novel technologies in HCC research.

Main Methods:

• Review of existing literature on HCC preclinical models.
• Categorization of models based on technology (chemical, dietary, transgenic, transposon, organoid, in silico).
• Comparative analysis of model efficacy, limitations, and applications.

Main Results:

• Traditional chemical and dietary models have limitations in reflecting human HCC complexity.
• Transgenic, transposon, organoid, and in silico models offer advanced tools for studying HCC.
• Each model type presents unique advantages for specific research questions in liver cancer.

Conclusions:

• Preclinical models are essential for unraveling HCC molecular pathogenesis.
• Novel models significantly enhance the development of new therapeutic strategies for liver cancer.
• Careful selection of appropriate HCC models is critical for successful preclinical research.
