Matrix Metalloproteinases in Hepatocellular Carcinoma: Mechanistic Roles and Emerging Inhibitory Strategies for...

Area of Science:

• Oncology
• Biochemistry
• Molecular Biology

Background:

• Hepatocellular carcinoma (HCC) presents a significant global health challenge due to late diagnosis and treatment resistance.
• Matrix metalloproteinases (MMPs) are key enzymes involved in extracellular matrix remodeling, influencing tumor growth, invasion, and metastasis in liver cancer.
• MMPs also regulate crucial aspects of the tumor microenvironment, including angiogenesis, inflammation, and immune evasion, contributing to HCC progression.

Purpose of the Study:

• To review the multifaceted roles of MMPs in hepatocellular carcinoma (HCC) pathobiology.
• To evaluate emerging therapeutic strategies for targeting MMPs in liver cancer.
• To highlight advancements in MMP inhibition for improved specificity and efficacy.

Main Methods:

• Literature review synthesizing current knowledge on MMPs in HCC.
• Analysis of preclinical data on novel MMP targeting approaches.
• Evaluation of the impact of MMP modulation on tumor progression and therapeutic response.

Main Results:

• Aberrant MMP expression correlates with aggressive HCC features and poor patient survival, marking them as prognostic indicators.
• Previous MMP inhibitor attempts faced challenges with specificity and toxicity.
• Recent advances in drug design and delivery offer potential for selective, context-dependent MMP modulation.

Conclusions:

• Targeting MMPs holds significant promise for improving liver cancer treatment.
• Enhanced specificity and delivery strategies are crucial for overcoming limitations of past MMP-targeted therapies.
• MMP inhibition may enhance the efficacy of existing treatments, including immuno-oncology agents, for HCC.
