Antithrombin attenuates the progression of hepatocellular carcinoma by regulating neutrophil/interleukin-8 signaling

Role of Coagulation Factors in Hepatocellular Carcinoma: A Literature Review

Hepatocyte carcinoma (HCC) is a globally prevalent neoplasm with profound effects on morbidity and mortality rates. This review summarizes the complex interactions between coagulation abnormalities and the pathophysiological mechanisms underlying HCC. Essential coagulation biomarkers, such as P-selectin, thrombomodulin, d-dimer, prothrombin, and von Willebrand factor, are reviewed for their diagnostic, prognostic, and therapeutic significance. The contribution of these biomarkers to tumor progression, metastatic spread, and patient prognosis is highlighted through a synthesis of contemporary research findings. In addition, this review highlights the underlying mechanisms linking coagulation pathways to HCC pathogenesis and explores potential therapeutic targets. An integrative perspective on the role of coagulation markers in HCC may improve clinical management strategies for patients affected by this malignancy.

Recent progress in molecular mechanisms of postoperative recurrence and metastasis of hepatocellular carcinoma

Hepatectomy is currently considered the most effective option for treating patients with early and intermediate hepatocellular carcinoma (HCC). Unfortunately, the postoperative prognosis of patients with HCC remains unsatisfactory, predominantly because of high postoperative metastasis and recurrence rates. Therefore, research on the molecular mechanisms of postoperative HCC metastasis and recurrence will help develop effective intervention measures to prevent or delay HCC metastasis and recurrence and to improve the long-term survival of HCC patients. Herein, we review the latest research progress on the molecular mechanisms underlying postoperative HCC metastasis and recurrence to lay a foundation for improving the understanding of HCC metastasis and recurrence and for developing more precise prevention and intervention strategies.

Serpinc1 Acts as a Tumor Suppressor in Hepatocellular Carcinoma Through Inducing Apoptosis and Blocking Macrophage Polarization in an Ubiquitin-Proteasome Manner

Serpinc1 is a serine protease inhibitor in the coagulation cascade, but its role in tumor biology remains obscure. Here, we report an unexpected role of serpinc1 in suppression of hepatocellular carcinoma (HCC). In HCC patients, the mRNA and protein expression of serpinc1 is upregulated, which is negatively correlated with tumor grade, and has a better prognosis than patients with low serpinc1. In addition, patients with high expression of serpinc1 generally have a better tumor immune microenvironment, accompanied by changes in multiple immune cells and mediators. In particular, tumor-promoting M2 macrophages are negatively correlated with serpinc1 expression and the prognosis of HCC patients. In vitro experiments further show that overexpression of serpinc1 inhibits the growth of HCC cells (HepG2 and SMMC7721) by inducing apoptosis. Accordingly, cell co-culture experiments reveal the direct role of serpinc1-overexpressed HCC cells in inhibiting the formation of M2 macrophages. Subsequent unbiased quantitative proteomic and ubiquitinome analyses identify that multiple poly-ubiquitination of proteins involved in signal pathways (such as autophagy, apoptosis, lactate metabolism, and VEGF signaling) are regulated by serpinc1. Overall, these findings establish a serpinc1-dependent ubiquitin-proteasome system to control apoptosis and antitumor immunity.
