Progress in basic and clinical research of targeted drugs for primary hepatocellular carcinoma

Influence of tumor microenvironment on angiogenesis in hepatocellular carcinoma

Liver cancer is one of the main malignant tumors that endanger human health, and hepatocellular carcinoma (HCC) is the most common histological type of this heterogeneous cancer. The tumor microenvironment (TME) is a dynamic system composed of tumor cells and tumor-related stroma. HCC can form tumor-related blood vessels through a variety of angiogenesis modes. Previous studies have shown that various components of TME mediate HCC angiogenesis in multiple ways, which brings big challenges to clinical anti-angiogenesis therapy. This article reviews the research progress of HCC angiogenesis model and the role of TME in the regulation of HCC angiogenesis, with an aim to provide a reference for basic and clinical research of liver cancer.

Progress in research on association between cell signal transduction pathways and hepatocellular carcinoma

Cell signal transduction refers to the process by which a signal molecule induces signal transduction in a cell by stimulating the cell membrane or intracellular receptor, thereby affecting the biological function of the cell. In recent years, studies have found that the activation or inhibition of certain cell signal transduction pathways plays an important role in the development and progression of hepatocellular carcinoma. This article will review the recent research progress in the understanding of the role of some common signal transduction pathways in hepatocellular carcinoma.
