HCC-LM3 Cells

The HCC-LM3 cell line is an established model for studying hepatocellular carcinoma (HCC), particularly due to its high metastatic potential. This cell line has been instrumental in uncovering mechanisms related to tumor proliferation, migration, and treatment resistance. Research on HCC-LM3 cells has revealed their involvement in exploring drug responses and the molecular pathways influencing cancer aggressiveness. For example, circular RNA circMRPS35 has been shown to play an oncogenic role in HCC-LM3, promoting cell proliferation, migration, invasion, and chemoresistance, particularly to cisplatin. Mechanistically, circMRPS35 functions by sponging microRNA-148a-3p, leading to the upregulation of Syntaxin 3 (STX3), which modulates phosphatase and tensin homolog (PTEN) stability through ubiquitination and degradation.

In addition, studies have identified significant metabolic shifts in HCC-LM3 cells that correlate with tumor growth and survival. This cell line, along with other HCC models, demonstrates marked alterations in glucose and lipid metabolism, which support rapid tumor proliferation and are considered hallmarks of liver cancer. Research employing single-cell RNA sequencing has illuminated how metabolic heterogeneity within hepatocyte subpopulations impacts prognosis and therapeutic outcomes. Notably, metabolic pathway analyses in HCC-LM3 have been essential for identifying potential biomarkers and therapeutic targets for improved clinical strategies.
