Luciferase reporter cell line Huh7 is a cellular model engineered to study gene expression regulation, featuring a luciferase reporter system integrated into the genome. The Huh7 cell line was obtained in 1982 from a Japanese male patient who was 57 years old and had hepatocellular carcinoma. It is an important resource for a variety of research projects. The characteristics of these cells include adherent proliferation, strong differentiation, epithelial shape, and AFP positive. Notably, they are susceptible to hepatitis C virus (HCV) but do not carry the hepatitis B virus (HBV), which makes them perfect for researching the connection between HCV infection and liver cancer.
Huh7 cells are used not only to study carcinogenesis but also to clarify metabolic pathways, gene expression regulation mechanisms, and very-low-density lipoprotein (VLDL) production. Their flexibility includes being used as a model system to research dengue virus replication within liver cells, as well as producing recombinant proteins such as erythropoietin. Additionally, they are often used in xenograft animal models.
More than 70 million people globally are chronically infected with the hepatitis C virus (HCV), which is the main cause of liver cancer in the majority of those nations. The Luciferase Reporter Cell Line - Huh7 was employed by the researchers to examine the dynamics of Hepatitis C virus (HCV) infection. By utilizing gene expression profiling on several Huh7 variants, 34 potential host variables that impact HCV permissiveness were discovered. Seven candidates, including THAP7 and NR0B2, were validated by knock-down tests that demonstrated increased HCV replication upon overexpression. Notably, the ideal expression level of NR0B2 in highly permissive cells indicates a delicate balance impacting the metabolism of cholesterol and bile acid, which is essential for the regulation of HCV replication. Our knowledge of viral pathogenesis and possible treatment targets is advanced by these findings, which clarify important host genes influencing HCV tropism in Huh7 cells.

1. Liver cancer research: The Huh7 cell line originated from a Japanese male hepatocellular carcinoma patient in 1982. By introducing the Luciferase reporter system, it can be used to study the gene expression regulation mechanism and explore the occurrence and development of liver cancer.
2. Virus infection mechanism research: Huh7 cells are susceptible to hepatitis B virus (HCV) infection, but do not carry hepatitis B virus (HBV), making it an ideal model for studying the association between HCV infection and liver cancer.
3. Metabolic pathway and gene regulation research: It is used to clarify metabolic pathways, gene expression regulation mechanisms, and very low-density lipoprotein (VLDL) production, providing important support for liver biology research.
4. Disease model and protein production: Huh7 cells are flexibly used in the study of erysipelas virus replication in hepatocytes, as well as the production of recombinant proteins such as erythropoietin, providing a reliable platform for disease model construction and protein production.
5. Transplant animal model: It is often used in xenotransplant animal models to provide a deeper understanding of liver cancer research.
Customer Q&As
Luciferase Reporter Cell Line - How does the Huh7 reporter cell line perform in terms of luciferase activity and expression stability?
A: The Huh7 Luciferase reporter cell line is known for its high level and stable luciferase activity and is suitable for a variety of research applications. This cell line has been carefully selected and optimized to ensure stable expression of luciferase within cells. Whether it is a short-term experiment or a long-term culture, the luciferase activity remains consistent and will not decrease significantly as the number of passages increases. This stability is crucial to ensure the reliability and reproducibility of experimental data. In addition, each batch of cell lines undergoes strict quality control and verification to ensure high quality and consistency.
How to optimize experimental conditions to obtain reliable results when conducting drug screening experiments using the Huh7 Luciferase reporter cell line?
A: When conducting drug screening experiments using Huh7 Luciferase reporter cell lines, it is crucial to optimize experimental conditions. First, ensure that the cells are growing in optimal conditions and select appropriate culture media and culture conditions, including temperature, CO2 concentration, etc. Secondly, the addition time and concentration of the drug must be precisely controlled. It is recommended to use the gradient dilution method to determine the optimal working concentration. At the same time, use high-quality luminescent substrates (such as D-luciferin) and perform detection at appropriate time points to ensure the peak of the luminescent signal. For the measurement of luminescence signals, use a luminescence detector with high sensitivity and low background noise, and set reasonable measurement parameters (such as integration time). Additionally, ensure that each experiment has appropriate positive and negative controls to verify the actual effect of the drug and the accuracy of the experiment.
How to ensure the accuracy and reproducibility of results when analyzing luminescence data from Huh7 Luciferase reporter cell lines?
A: When analyzing luminescence data from a Huh7 Luciferase reporter cell line, ensuring the accuracy and reproducibility of your results requires several critical steps. First, perform data preprocessing, including removing outliers and background noise. Secondly, perform normalization processing and use internal standard or standard curve method to eliminate systematic errors between experiments. Then, the experimental data were statistically analyzed and the mean and standard deviation were calculated to evaluate the variability of the data. In order to improve the reliability of the data, it is recommended to repeat the experiment multiple times and use charts or images to visually display the data for easy observation and comparison. Additionally, experimental conditions and parameters were recorded in detail to allow for experimental replication and result verification when needed.
