Luciferase reporter stable cell line HEK293 is engineered to express a luciferase reporter gene for studying gene regulation and signal transduction pathways. The firefly-derived luciferase reporter gene produces an enzyme that catalyzes the oxidation of luciferin, which releases light. It is possible to quantify this emission in order to assess the activity of particular cell signaling pathways or promoters.
Because of their strong proliferation and transfectability, human embryonic kidney cells, or HEK293 cells, are often utilized in scientific research. Since these cells are adherent, they may be grown under normal cell culture conditions with the right supplements and medium. They develop in a monolayer and have an epithelial shape, which makes them appropriate for experiments and high-throughput screening.
Progranulin plays a variety of roles in both physiological and pathological processes, such as neurodegeneration, inflammation, cancer, wound healing, and embryonic development. The HEK293 cells were used to create a stable cell line for the luciferase reporter to study the transcriptional regulation of the PGRN gene. The luciferase gene was integrated into the genome using CRISPR/Cas9, with the native PGRN promoter serving as its master regulator. The luciferase gene's site-specific integration was validated by PCR findings. Applying a CRISPR/Cas9 transcription activation/repression system and treating the cells with phorbol ester (phorbol 12-myristate, 13-acetate), which is known to activate PGRN expression, allowed them to validate this approach. The direct correlation between the luciferase activity and the PGRN promoter activity suggests that the approach is useful for investigating the transcriptional regulation of PGRN and may have applications in drug screening that targets PGRN.
