PGK, mammalian promoter

Promoter for expression of genes in mammalian cells

Contribution: NUDT_CHINA 2019

Summary：in this part, we made contributions to the quantitative characterization data of mammalian PGK Promoter. We measured the strength of this promoter by expression change of firefly luciferase at different time.

Characterization: To characterize the PGK promoter at different time, we used firefly luciferase as its reporter gene. For method, we transfected equal quantity of pmirGLO into liver carcinoma cell line HepG2. Cells were cultured in High Glucose Dulbecco's Modified Eagle Medium with 10% FBS and under condition of 37℃, 5% CO2. 0, 6, 12 and 24h after transfection, cells were dissociated for luciferases (both firefly and renilla). Data was collected by Beyotime™ RG027 Dual Luciferase Reporter Gene Assay Kit and analyzed by ImageJ. Results are shown below.

Figure 1. PGK-drived firefly luciferase RLU in HepG2 cell line after transfection and culturing for 0, 6, 12 and 24 hours.

Conclusions drawn from the results that within 24h, initiation strength of the mammalian PGK promoter keeps rising and reached maximum at 24h after transfection. Sequence and Features

-Summary：in this part, we made contributions to the quantitative characterization data of mammalian PGK Promoter. We measured the strength of this promoter by expression change of firefly luciferase at continous time set after transfection of 6, 18, 30, 42 and 54 hours in HepG2 cell line, and made a curve showing how the strength of PGK promoter changes within 48 hours.
