Hepatocellular carcinoma: insight from animal models

Area of Science:

• Hepatocellular carcinoma (HCC) research
• Animal modeling in oncology
• Liver cancer pathogenesis

Background:

• Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality globally.
• Key risk factors for HCC are known, but carcinogenesis and metastasis mechanisms require further elucidation.
• Advanced animal models are vital for studying HCC's molecular, cellular, and pathophysiological aspects.

Purpose of the Study:

• To review existing animal models relevant to hepatocellular carcinoma (HCC) development, metastasis, and treatment.
• To highlight the utility of these models in understanding HCC pathogenesis and evaluating therapeutic strategies.

Main Methods:

• Overview of transgenic mouse models for Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infection.
• Discussion of animal models designed to study HCC metastasis mechanisms and microenvironment interactions.
• Examination of animal models used for investigating novel HCC treatment modalities.

Main Results:

• Transgenic models demonstrate that viral genes (HBV, HCV) can initiate or promote liver carcinogenesis.
• Metastasis models offer platforms for elucidating invasion mechanisms and testing interventions.
• Various models are available for assessing the efficacy of new therapeutic approaches for HCC.

Conclusions:

• Animal models are indispensable tools for advancing the understanding and treatment of hepatocellular carcinoma (HCC).
• The review discusses criteria for ideal HCC animal models to guide future research.
• Continued development and application of animal models are essential for combating HCC.
