Transcriptomic analysis of hepatocellular carcinoma cell lines HepG2 treated with Sorafenib and transfected with miR-200c-3p inhibitor, and miR-222-5p and miR-512-3p mimics

Hepatocellular carcinoma (HCC) is one of the most common causes of death worldwide and the fourth most prevalent type of cancer. Whereas curative treatments such as liver transplantation, ablation or surgery are optimal for early stages, only paliative treatments are given to intermediate and advanced stages of the disease. Despite the introduction of immune regulators as first-line treatments for advanced stages, Sorafenib is still the standard of care in the clinical practice. In cell lysates, anti-tumoral properties of Sorafenib were related to upregulation of miR-200c-3p (anti-tumoral miRNA) at 6 hours of treatment and downregulation of miR-222-5p and miR-512-3p (pro-tumoral miRNAs) at 24 hours. We have identified these miRNA biomarkers of Sorafenib treatment response in plasma of patients with advanced HCC treated with Sorafenib. In particular, miR-200c-3p has been related to increased survival benefit whereas miR-222-5p and miR-512-3p have been related to worse prognosis. Our study has sequenced HepG2 cells treated with Sorafenib and miR-200c-3p inhibitor, and transfected with miR-222-5p and miR-512-3p mimics to unravel the molecular pathways governing Sorafenib response Transcriptomic analysis of hepatocellular carcinoma cell lines HepG2 treated with Sorafenib and transfected with miR-200c-3p inhibitor, and miR-222-5p and miR-512-3p mimics. Three biological replicates are provided for miRNA and control transfected cells, as well as Sorafenib and control treated cells.
