| Organism |

Expression profiling by high throughput sequencing

| Summary |
In our work, we uncovered a critical role for cholesterol homeostasis in terminal erythropoiesis. The master transcriptional factor GATA1 binds to Sterol-regulatory element binding protein 2 (SREBP2) to downregulate cholesterol biosynthesis, leading to a gradual reduction in intracellular cholesterol levels. To reveal genetic interactions and epistatic relations between GATA1 and SREBP2 on depth at the whole genome level, we performed RNA sequencing to analyze the gene expression profiles change between treated with Vehicle or β-estradiol in overexpressing active SREBP2 G1E-ER4 cells.

| Overall design |
G1E-ER4 cells were transduced with retrovirus to express active SREBP2 (1-468aa), cells were then treated with Vehicle or β-estradiol (200nM) for 6 h, and total RNA was extracted using the TRIzol reagent. RNA sequencing was conducted using the BGIseq500 platform (Shenzhen, China) in triplicate.
