Objects: To investigate the effect of CXCL13 (C-X-C motif chemokine 13) on hepatocellular carcinoma and clarify the potential mechanisms.
Methods: 32 patients with hepatocellular carcinoma and 12 healthy controls were recruited for analyzing the expression of CXCL13 by RT-PCR (reverse transcription-polymerase chain reaction). ELISA (enzyme-linked immune-sorbent assay) was used to test the concentration of serum CXCL13. The interaction between CXCL13 and Wnt signaling was analyzed by western blot. In vitro PBMCs cultured with HepG2 supernatant, the levels of IL-12, IL4, IL-6, and IL-17, and four IgG subclasses were detected by ELISA.
Results: The rate of high expression CXCL13 was 63.4% in advanced HCC patients, and the serum CXCL13 was also at a high level in stage IV HCC patients. Meanwhile CXCL13 level was positively correlated with serum ALT (Alanine Transaminase) and AST (Aspartate Aminotransferase). CXCL13 and Wnt/β-catenin signaling shared a positive feedback loop. Furthermore, CXCL13 could obviously promote the expressions of IL-12 and IL-17, and induce IgG4 secreted by B cells.
Conclusions: The effect of CXCL13 on promoting liver cancer is related to the activation of Wnt/β-catenin pathway and the facilitation of IL-12, IL-17 and IgG4. CXCL13 plays an important role in the progression of HCC, and it may act as a potential target for the diagnosis and treatment of HCC.
Due to current challenges in the early detection, less than 40% of individuals diagnosed with hepatocellular carcinoma (HCC) are viable candidates for surgical intervention. Therefore, validating and launching of a novel precise diagnostic approach is essential for early diagnosis. Based on developing evidence using circulating tumor cells and their derivatives, circulating miRNAs, and extracellular vesicles (EVs), liquid biopsy may offer a reliable platform for the HCC's early diagnosis.
Background: Abnormal expression of six-transmembrane epithelial antigen of prostate 4 (STEAP4) has been implicated in the carcinogenesis of hepatocellular carcinoma (HCC). However, the biological role and regulatory mechanisms of STEAP4 in HCC remain unclear.
Methods And Results: Here, we analyzed STEAP4 expression levels and differentially expressed genes (DEGs) between STEAP4 high- and low-expression groups using multiple databases.
Alcohol-associated liver disease (ALD), primarily caused by chronic excessive alcohol consumption, is a leading cause of chronic liver disease worldwide. ALD includes alcohol-associated steatotic liver, alcohol-associated hepatitis (AH), fibrosis, cirrhosis, and can even progress to hepatocellular carcinoma (HCC). Existing research indicates that the risk factors of ALD are quite numerous.
