This technology involves studying the role of the Tumor-Associated Calcium Signal Transducer 2 (TACSTD2) gene in Hepatitis C Virus (HCV) infection and hepatocellular carcinoma. Researchers perform transcriptomics analysis on liver specimens from HCV-infected patients, identify TACSTD2 as a key gene, and create a stable cell line that overexpresses TACSTD2 to investigate its impact on HCV infection and replication. This technology aims to provide insights into the molecular mechanisms of HCV infection and its association with liver cancer.
